Imagery is defined by Martens (1987) as:
“An experience similar to a sensory experience (seeing, feeling, hearing), but arising in the absence of the usual external stimuli” (Martens, 1987 pp.78)
Cox, (1990) explains imagery as a cognitive intervention technique used prior to competition and Cashmore (2002) iterates the subjects need to be able to construct clear and real images which control their content and outcome. The evidence of mental imagery effectiveness will be further examined throughout the study.
2.5.1 Internal Imagery
It is important in this study to distinguish between the two types of imagery. Mental Imagery involves two separate approaches, external imagery and internal imagery. Jeannerod, (1994) and Smyth & Waller, (1998) refers internal imagery to a kinaesthetic approach; it involves two keys components, feelings of movement and sensations of force or effort. White, Hardy (1995) & Callow (1999) created assumptions upon internal visual imagery as being effective when used with kinaesthetic imagery and also with both visual perspectives. Research by Mahoney, Avener (1977) & Orlick, Partington et al (1980) has shown that elite athletes are more likely to practice imagery from an internal perspective as compared to non-elite athletes, who are more likely to practice imagery from an external perspective.
2.5.2 External Imagery
External imagery is seen as the second method involved in mental imagery. Callow and Hardy (1999) described external imagery as:
“A person viewing himself from the perspective of an external observer” (Callow & Hardy, 1999)
Also Woods (1998) and Owens (2000) describe external imagery as seeing yourself from the outside, as though watching yourself on videotape. The external imagery method allows the athletes to gain quality feedback to ensure performance enhancement throughout the training. (Weinburg & Gould, 1995)
2.6 Mental Imagery Effectiveness
Mental imagery has been widely accepted as providing positive effects towards performance in sport. These suggestions have been both supported both by world performing athletes and research findings within the subject area. (Howe, 1999). A study conducted in 1988 by Orlick and Partington found that 99% of the Canadian Athletic team used mental imagery prior to the 1984 Olympics. The authors found imagery to be highly effective in enhancing the athlete’s performance, which is also supported through similar research carried out by Murphy, Jowdy & Durtschi, (1990) concluding that 100% of sports psychology consultants and 90% of Olympic athletes use some form of imagery, whereby 97% of athletes find the method to be very effective. (Weinberg, Gould, 1995, p275)
Numerous studies have revealed that imagery has been used effectively by performers in various sports (Martin, Moritz, & Hall, 1999) and in a variety of ways (Rushall, 1997). Cumming, Shambrook & Hall, (2002) revealed a study on the influence of imagery. The evidence showed imagery ability proved a factor in the different imagery use between each participant. Also each participant’s competitive level proved a factor on the effectiveness of imagery.
Some later studies have demonstrated the effectiveness of imagery such as one using a golfer (Thompson, Bell, 2005) and (Nicholls, Polman, 2004). More significantly earlier studies by Feltz and Landers (1983) have provided the most comprehensive review of mental imagery literature. The two authors have concluded from numerous studies:
- Mental imagery effects are primarily associated with cognitive-symbolic rather than motor elements of the task.
- Mental imagery effects are not limited to early learning; later stages prove to produce more effectiveness.
- It is doubtful that mental imagery effects are produced by low-gain innervations of muscles to be used during actual performance
- Mental imagery functions to assist the performer in psychologically preparing for the skill to be performed.
(Gill, 2000, p67)
Since Feltz and Landers (1983) research, many authors have not been able to provide sufficient evidence to challenge Feltz and Landers (1983) insights within imagery literature. More recently however, a reasonable amount of past research by Holmes, Collins & (1996), , (2001) Weinberg, Butt, Knight, Burke & Jackson, (2003) and also Callow & Hardy (2001) have concentrated their studies towards effectiveness of mental imagery between numerous sports, from netball to golf. Weinberg, Butt, et al (2003) revealed that athletes used imagery most during difficult situations where pressure is high. The Sports Imagery Questionnaire created by SIQ Hall, Mack, Paivio & Hausenblas (1998) was developed to gather primary information from the athlete. Weinberg, Butt et al (2003) revealed from this questionnaire that athletes predominantly use imagery before competition. Callow
and Hardy (2001) found similar findings as well as discovering oriented imagery was the only significant predictor of variance in confidence. Although Ryan & Simons (2001) stated physical practice was more effective than mental imagery, while both were better than no practice.
Corbin (1972) has suggested that research through the subject area has revealed inconclusive evidence. He claims results examining different tasks with different individual characteristics can not provided reliable findings to establish a formative conclusion. Martens (1987) also stated how it is uncertain how much motor imagery helps athletes learn an entirely new motor skill. Evidence has indicated that motor imagery is most helpful for complex sports skills once athletes have a reasonable idea of what the skill looks like and feels like.
2.7 Internal Vs External
Many authors have revealed that internal imagery is used more often by top athletes than external imagery. (Elton, 1994) Steve Elton agrees that internal imagery is more effective than external imagery in improving an athlete’s competitive performance. On the other hand, Sugarman (2007) describes external imagery as being an effective tool when using for error correction. The method allows the participant to see what their actually doing wrong as a coach would.
Both types of imagery are beneficial, however it is useful for the athletes to be able to see images from behind a camera, in their mind. External visual imagery is more effective for the acquisition and performance of skills that rely on form for their successful execution. Cheadle (2002). On the other hand, internal imagery is referred to a kinaesthetic aspect; it involves two key components, which are explained by Jeannerod, (1994); Smyth & Waller, (1998) as feelings of movement and sensations of force or effort. Internal imagery has also been proven to produce more neuromuscular activity than external imagery (Hale, 1982; Harris & Robinson, 1986). Past research has shown that top athletes are more likely to practice imagery from an internal perspective; this is compared with non-elite athletes who are more likely to practice external imagery (Mahoney & Avener, 1977; Orlick & Partington, 1986, Rotella et al, 1980). Although Gordon, Weinberg & Jackson (1994) conducted a study on the ‘Effect of Internal and External Imagery on Cricket Performance’ and proved no significant performance differences between external and internal imagery groups. There are many studies involving external versus external imagery with contradicting results. Hall et al, (1990) also found similar results to Gordon, Weinberg & Jack (1994) with additional information towards athletes indicating that they switch between each type of imagery. The athlete tends to switch between each type of imagery depending on the task and difficulty.
2.8 Mental Imagery Theories
A number of past authors have generated proposed theories towards the function and process of mental imagery. The theories have been proposed by sport psychologists in order to explain the complex process. The theories include The Bioninformational Theory (Lang, 1977), The Psychoneuromuscular Theory (Carpenter, 1894), and The Symbolic Learning Theory (Sackett 1934), which all emphasize that mental imagery can help an athletes performance physically and mentally.
2.8.1 The Bioinformational Theory
The Bioinformational theory is claimed to be the best-developed theoretical explanation of mental imagery. (Weinberg.R & Gould.D, 1995). Developed by Lang (1977, 1979, 1985), he describe the model as a cognitive and emotional change produced by efficient desensitization (decrease of anxiety) and exposure therapy using an informal cognitive-emotional-behavioral method. (Tyron, 2004) Weinberg and Gould explain that an image within the brain can have two main types of propositions.
- Response Propositions
- Stimulus Propositions
Stimulus propositions are images and statements that portray specific stimulus features of any situation to be imagined. On the other hand response propositions are statements that describe the imager’s response to the actual scenario, which are intended to create physiological activity. (Weinberg & Gould, 1995). Lang’s theory involving the imagery process has been backed up by various authors. Drobes (1995), Hall (1999) and Morris (1998) have all studied the imagery process and gathered similar evaluations as Lang.
2.8.2 The Psychoneuromuscular Theory
The second theory developed by Carpenter (1894) describes the imaginary movements created muscle enervation similar to those used in actual movement. (Cashmore, 2000). The Psychoneuromuscular theory suggests that subliminal efferent commands are sent from the brain to the muscles. (Cox, 2002) There have been a variety of studies conducted with the Psychoneuromuscular theory being examined. Jowdy and Harris (1990) reemphasized Carpenters (1894) theory by explaining an increase in electrical activity within the muscles is related with imagery. Jacobson (1931), Suinn (1972, 1976), Martin, Slade & Landers (2002), Decety (1996) and more recently Murphy (2005) all have conducted similar research to Jowdy and Harris (1990). Decety (1996) discovered that when an athlete imagines starting a movement, various areas of the brain become active. Although Martin, Slade & Landers (2002) noted that electrical activity produced by the muscles does not mirror the actual pattern of activity when performing a certain movement. (Weinberg & Gould, 1995). Cox (2002) claims the Psychoneuromuscular theory is the most believable theory for why imagery facilitates physical performance and learning although Cashmore (2000) states there proves to be weak support to back this theory.
2.8.3 Symbolic Learning Theory
The Symbolic learning theory developed by Sackett (1934) holds opposing views to Carpenters (1894) Psychoneuromuscular theory. The symbolic theory differs in that subliminal electrical activity in the musculature is not vital. (Cox, 2002) The theory examines imagery working as a “mental blueprint” that can be used later through the process (Cashmore, 2000) as well as providing a function as a coding system to aid athletes to understand competitive movement patterns. (Weinberg & Gould, 1995). Driskell, Cooper (1994) and Feltz & Landers (1983) have all studied the symbolic theory in relation to participants performing imagery constantly superior on tasks that were more cognitive than motoric activities. Although these authors have concluded positive results Cashmore, (2000) illustrates there is still weak support with the theory process.
There have been a variety of theories relating to the actual imagery process involved through an athlete’s brain. Bioinformational theory Lang (1977), the Psychoneuromuscular theory, Carpenter (1894) and the Symbolic learning theory Sackett (1934) are just a few of proposed theories, others include the Triple-Code, Attention and Arousal Set theory and the Sensory Mode. Overall, a high majority that imagery has been recognised to work at a cognition level proposed by Martin & Hall (1995) as well as acting as a motivational tool when performing. This theory is also back up by Paivio (1985) explaining also the
“The motivational function of imagery is the use of imagery to experience goal attainment”. (Cox, 2002, p267)
2.9 Imagery types
Five main types (Motivational Specific, Motivational general Mastery, Motional general mastery, Motivational general Arousal, Cognitive Specific and Cognitive General)
Recent research has suggested that, for maximum effectiveness, the participant should match the type of imagery with their required outcome. There are five main categories of imagery:
- Motivational-specific (MS)
- Motivational general-mastery (MG-M)
- Motivational general-arousal (MG-A)
- Cognitive specific (CS)
-
Cognitive general (CG)
Each separate category creates different methods for improving overall performance and confidence. Motivational-specific imagery involves seeing yourself winning an actual event. This image’s helps to boost motivation and overall effort during training and competition. Motivational general-mastery is a similar motivational strategy, although the athlete is creating images from past circumstances were there have been difficult circumstances. Motivational general-arousal reflects feeling of relaxation and stress, there has been strong evidence to suggest MG-A controls an athlete’s heart rate. (Martens, 1987) Cognitive specific is seen as the most common type of imagery. The method involves seeing yourself perform specific skills, such as a cover drive cricket shot. Each separate method has the ability to overlap with one another, for example using imagery towards a specific skill, such as a cricket shot (CS), overlapping with a positive outcome during a competitive match (MS). Past research by Bell &.Thompson (2004) claims cognitive specific imagery to be more effective than any other method, it also suggests that if you choose the wrong type of imagery, there may not be any effect. Although research conducted by Salmon & Hall (1994), on the use of imagery on soccer players, reported players used imagery more for its motivational function rather than its cognitive function.
2.9.1 Pavio’s Two Dimensional Model
Pavio (1985) revealed that cognitive and motivational functions are involved within the imagery process. The diagram below explains that the cognitive function could be either situation-specific or general, and the motivational function could be either situation-specific or general. (Cox, 2002, p267)
Purpose
Motivational Cognitive
(Hall et all, 1998, Cox, 2002, p268) Figure-2.9 Pavio’s Two Dimensional Model
The model shows that athletes will select a different imagery types depending on the sporting situation at the time. The model provides illustration for each sporting situation and shows the potential outcome and enhancement of a specific skill. Pavio’s two dimensional model was utilised by Hall, Mack, and Hausenblas (1998) to develop the Sport Imagery Questionnaire (SIQ). The SIQ is a 30 item questionnaire that outlines imagery characteristics into the five subscales. Invented by Hall et al (1998), the scoring systems indicates a motivational subscale of the SIQ which has been suggested to be more expressive when used with elite high school athletes than using average ability high school athletes. (Hall et al, 1998). Hall concluded that the SIQ enables coaches to assess athlete’s cognitive and motivational imagery abilities.
2.10 Experience Level and Attentional Focus
Weinberg and Gould (1999) have recognised experience level as a major factor affecting the effectiveness of imagery upon an athlete. Since imagery experiments have begun, authors have spent less attention to the individual differences relating to effectiveness of imagery. (Gill, 2000) Many authors have concentrated upon the mental imagery process rather then the external or internal influences which cause differences in effectiveness.
2.10.1 Experience Level
The skill level of the performer is an important factor contributing to the effectiveness of imagery. Many authors have established that experienced performers benefit far more than novice performers. (Cox, 2002) Feltz and Lenders, (1983) produced a journal on ‘Effects of mental practice on motor skill learning and performance: A meta-analysis’ which concluded that elite athletes benefit more from imagery then average athletes.
Although Clack (1960) and Cobrin (1967) discovered results which stated novice learning benefit more from imagery than experienced. This was backed up by Schmidt (1982) by suggesting mental imagery is more beneficial during the early stages of learning. (Driskell et al, 1994) Hird, Landers, Thomas, & Horan, (1991) as well as Ryan & Simons (1981) also have suggested practice is most effective for activities that require some thinking and planning. Overall it has been seen that imagery will benefit novice performers during the learning of cognitive elements whereas experienced performers utilise imagery more during refined skill training. (Weinberg and Gould, 1999)
2.10.2 Attentional Focus
Attentional focus is defined as:
“As the influence of instructions to consciously attend to specific information during the production of action”. (Ceccato et al, 2003, p593, issue 21)
Numerous recent studies have proved that athlete’s focus of attention has an important influence on the overall performance and learning of specific skills. (Wulf, Landers, Mercer and Tonner, 2004). Different factors are thought to contribute to different types of attentional focus. (Woods, 1998) From this theory, Robert Nideffer created a model based on four types of attentional focus. External, internal, broad and narrow are claimed to be the proposed different types which can be combined together to create four dissimilar attentional focuses. Below is the model showing the four different types, Nideffer (1976):
Analysing the model it explains that an athlete’s focus of concentration can be broad or narrow, external or internal. For example arousal is predicted to narrow the window of attention surrounding a point of focus. (Tracy.J et al, 2000). Broad-external focus is thought to be used by top athletes anticipating opponent’s movements. On the other hand, broad-internal focus is dealt by analysing and planning a situation. Narrow-internal focus allows for a systematic approach while a narrow-external focus is attention whereby the person is avoiding distraction during an important situation. Overall each different type will come into reality for each separate subject. Some athletes will be more internal than external and other will be more narrow than broad. (Woods, 1998)
2.11 Summary of Literature Review
Mental preparation has been seen as an important aspect for any athlete, whether used for internal motivation or creating an edge over competitive opposition. (Morris & Summers, 1995) Throughout the literature review, the study has examined mental preparation through to mental imagery in comprehensive depth. Many authors and elite athletes have acknowledged that competitive sport involves a high percentage of mental activity.
“In training everyone focuses on 90% physical and 10% mental, but in the races its 90% mental because there's very little that separates us physically at the elite level” (E. Graham 2003)
Throughout conducting secondary research, it has become apparent when examining authors collective reviews over mental practice research, many results have been seen to contradict one another. A selective number of authors have evaluated mental practice as an effective tool to increase individual performance on any athlete. On the other hand, different authors have strongly questioned the actual effectiveness of mental practice through a number an influential factors. (Beasley, 1979) Although research is still being evaluated throughout the area, there haven’t been any recently published studies with regards to the overall effectiveness of mental preparation techniques. Sport psychologists have been providing athletes with a variety of methods throughout the years, but very few have provided reliable results when under examination.
The most relevant publication towards the study is the ‘Effect of Internal and External Imagery on Cricket Performance’ By Sandy, Weinberg & Allen, (1994). The results showed no apparent difference between each imagery group. Although it is known
Elton, 1994 and Smyth & Waller, (1998) concluded contrasting results. The examination of secondary research has strongly justified any reasoning for further primary research within the area.
This Study will focus on the examination of internal and external imagery as well as trying to complement previous imagery studies. The methods used within Sandy, Weinberg & Allen, (1994) study, has been adapted to develop an answer throughout this study, for which mental imagery is more effective than none.
3.0 Methodology
A methodology is a body of text which outlines the methods of conducting the experimental research of the study. The section will describe the key measuring tools being used throughout the experiment and also describe exactly how the research is going to be carried out. (Finn et al, 2000)
“The importance of this section cannot be over-emphasised” (Finn et al, 2000, p 235)
3.1 Objectives
Throughout the study it will aim to discover three main objectives, which are:
Objective 1: To establish which imagery perspective is the most effective through a series of cricket related tests.
Objective 2: To find out if there is any correlation between the effectiveness of the imagery perspectives among County standard cricket players against none County Standard with external influences.
Objective 3: To discover if imagery training is more beneficial than none imagery training and establish if the test results and findings compliment or contradict previous studies within the area.
3.2 Subjects
Eighteen (N=18) trained cricketers aged between 18-23 (20.2) took part in the study. All eighteen participants are members of the Lincoln University Cricket Society who train at least once a week throughout the winter and spring semesters and twice during the BUSA (British Universities Sports Association) season (March-May).
Each participant within the sample size contains different levels of skill and experience. All eighteen subjects have been chosen according to their level of batting ability. The sample size contains a variety of standards; from county opening batsmen to club level tail-enders.
All eighteen subjects completed a consent form (appendix A) prior to the study and were checked for any medical problems. The participants also filled out a pre study questionnaire (Appendix D) to gather information of standard of ability and past experiences with imagery training.
3.3 Equipment
- Cricket Bat
- 5 ½ ozs Senior Cricket Ball
- 6 plastic cones
- Batting Mat
- Bowling Machine
3.4 Pre-Test
Prior to the test, each subject within groups A and B were given imagery scripts according to their training method. Each participant then conducted a practice test in order to familiarise themselves with the procedure. The participants were also given consent forms, and as each subject were over eighteen, no parental approval was needed. The Mental Skills Questionnaire (MSQ) was also handed out to assess a number of external factors contributing towards imagery utilisation.
The eighteen participants were randomly designated into three groups before the study test. Internal imagery training, external imagery training and no imagery training were the designed programme groups with six members in each.
-
(Group A) The Internal Imagery Group conducted their training with a kinaesthetic approach. All six subjects were provided with a written script (appendix….) that was handed out one week before the test. The script was then performed 10 minutes before the test and repeated every day until the final experiment, 6 weeks later.
-
(Group B) The External Imagery Group conducted their training through the perspective of an external observer. All six subjects were provided with a written script (appendix….) that was handed out one week before the test. The script was then performed 10 minutes before the test and repeated every day until the final experiment, 6 weeks later.
-
(Group C) The no imagery Group, conducted neither Internal nor External training. All six subjects were given a thorough explanation of the test procedure and a practice before conducting the test in week one. The subjects then performed the same test 6 weeks later with no cognitive specific training.
3.5 Experimental Protocol
3.5.1 Study Design
Participants were required to perform a “cover drive” cricket shot from a stationary ball position in order to score the highest tariff score. The test was performed twice, with the second test involving a bowling machine to progress the test into real life sporting situations. Each test involved one practice shot and then 4 recorded cover drive shots. During the bowling machine test, the speed was consistently at 60mph for each batsman.
The cover drive is an aggressive and attacking shot which is played to a delivery which is pitched up or just a bit full of a good length, the participants were aiming to hit the ball along the ground towards the cover position. (Section 1)
Below is the intended set up for the test procedure. The diagram shows the test for right-handed batsmen, for lefthanders the test will be the opposite. Each participant will be given four tries at the test and the score will be given an average from all four attempts. Each cone will represent a different score; if the batsman strikes the ball correctly through the intended marker they will receive maximum points. Each shot will be analysed on the accuracy, technique and height. This test will carried out two times throughout the study to able the participants to improve their performance through imagery training.
In order to categorise the cricketers into beginner or advance, the subjects were asked to indicate their perceived cricketing ability from 1 to 10, 10 being county standard or higher.
3.5.2 Questionnaire
The Mental Skills Questionnaire (Bull, 2003) is used to identify mental strengths and weaknesses within athletes. The questionnaire analyses seven key factors towards the influence upon imagery effectiveness. These are: Imagery Ability, Mental Preparation, Self-confidence, Anxiety and Worry Management, Concentration Ability, Relaxation Ability and Motivation. Once the questionnaire has been completed the score of each section is divided by 24 and then times by 100 to give an overall percentage. For example:
18/24= 0.75 _ 0.75 x 100 = 75%
3.5.3 Textbook Cover Drive Shot
The cover drive shot in cricket is one of the hardest skills to perform in the game. The shot is normally played off a ball that is very full in length and just outside the off stump. The face of the bat must be slightly open and the batsmen must watch the ball all the way. The front shoulder is lead into the shot and the left foot is place beside the pitch of the ball. With a high elbow and straight bat the shot should be followed through naturally for an aesthetically pleasing shot and positive results. (Cricket Secrets, 2008)
There are also four main factors which can go wrong through the movement of the shot. Batsmen can over step a lot of the times with their front foot causing the deliver to pitch more of a Yorker length then a cover drive shot length. The next factor involves many cricketers not controlling their anxiety and panicking when the ball is released meaning for a rash decision and a not timed finish. Leaning back too far is also another problem many cricketers have while performing the shot. Leaning back can open the face of the bat and provide an easy edge to the slips. The weight must be balanced on the front foot to allow a strong balancing position. The final factor is foot placement. If the batsman plants his foot too far across to the off-side, then he/she may not be able to get inside the line of the ball to play the ball square of the wicket. (Cricket Secrets, 2008)

3.6 Statistical Analysis
Once all the data has been collected, a mean will be taken for each separate group with a standard deviation. Then the data will be examined using Ronald.A.Fisher’s (1890-1962) a one way analysis of variance (ANOVA) which is a collection of statistical models. This method compares the differences between the means of a number of samples to see whether they are larger than the differences expected by chance alone. (Williams.C & Wragg.C, 2004) The data will also be recorded within tables and graphs to make an overall comparison of the results.
4.0 Findings
4.1 Introduction
The results section will present the studies primary research findings. Throughout this section, data will be analysed to distinguish any relevancy towards the proposed study objectives. This section is an essential part of the study as it allows for added primary research which can be later compared, contradict or even complement previous studies.
Throughout the results section each imagery group will be analysed for improvement, consistency and comparison upon one another. Each group has a variety of experience and ability level. The internal (IN) imagery group (Group A,) has two county standard players with an overall batting ability average of M=6.3. The no (NI) imagery group (Group B), has no county standard batsmen although all the subjects are either 5 or above with an overall average M= 5.8. The final external (EX) imagery group (Group C) has a total of two county players with a batting average of M=7.3. All of the subjects are the same gender and within the same age range between 18-22, M= 20.2.
Through the first three graphs, the subjects are displayed on the ‘x’ axis with the test score scale along the ‘y’ axis. Once each imagery group is analysed, data will then be compared with questionnaire results relating to imagery ability and concentration.
4.2 Individual Group Scores, Internal Imagery Group (Group A)
Figure 4.2 Internal Imagery Test Scores
Descriptive Statistics
Table 4.2- Descriptive Statistics on Individual Group Scores, Internal Imagery
As can be seen above, performance scores were generally improved as a result of internal imagery training. The most significant increase was experienced from subject 5, contributing to the overall mean. (M=11.083) Overall each subject either increased their performance or maintained the same, no subjects decreased in performance.
4.2.1 No Imagery Group (Group B)
Figure 4.2.2-No Imagery Test Scores
Descriptive Statistics
Table 4.2.1- Descriptive Statistics on No Imagery Group
As seen above, comparison between group A, shows a decrease for the majority of subjects involved. Although the average mean through pre test M=8.667 is slightly lower than test 2 average M=8.750, there is an improved gap shown through standard deviation. One factor which could of determined any improvement, may be the experience level, as none of the six subjects an ability level of 10.
4.2.2 External Imagery Group (Group C)
Figure 4.2.2 External Imagery Test Scores
Descriptive Statistics
Table 4.2.2- Descriptive Statistics on External Imagery Group
As seen above, similar outcomes have been produced through external imagery as internal imagery. There shows a considerable difference between pre-test mean, M=7.833 and test 2 mean, M=11.167 with nearly all subjects improving in test scores.
Although no significant difference can be seen between the two imagery groups, there is a clear trend for improved performance as a result of imagery training within both groups.
4.2.3 Internal Vs External Vs No Imagery
Figure 4.2.3 Overall Mean Imagery Group’s Test Scores
Figure 6.4 displays the three imagery group’s average mean time through, pre-test, test 1 and test 2. (8.9 vs. 9.3 vs. 9.5) The results conclude an improvement in performance scores between IN and NI, EX groups. When subjected to the ANVOA statistical testing protocol, results showed no significant difference. (F=0.65, P= 0.938). Post Hoc Testing was also used, showing multiple comparisons between each separate group. (Additional data analysis is found in appendix G)

4.3 Individual Analysis
Through examining the imagery groups test results, it became apparent specific individuals scores stood out from the rest. One subject was taken from each group and analysed further with reference to the mental skills questionnaire.
4.3.1 Group A - Subject 5
Figure 4.3.1- Subject 5’s Questionnaire Results
Subject 5 (Age=19, Batsmen) within group A was seen as the highest performer of improvement through all three tests. (PT= 7, 1st = 8.5, 2nd = 15) These test results have seen to compliment subject 5’s mental skills questionnaire results. An imagery score of 83% brings justification to the overall improvement. Subject 5 also had one of the lowest pre test scores, explaining a low questionnaire score on confidence, anxiety and concentration, although this seems to contradict subject 5’s experience level.
4.3.2 Group B – Subject 6
Figure 4.3.2- Subject 6’s Questionnaire Results
Subject 6 (Age= 22, Bowler) within group B showed a dramatic decrease within test scores. (PT= 8 1st =7.5 2nd=6.5). The questionnaire results show a low score within concentration, anxiety and imagery, although imagery wasn’t a factor within subject 6’s test. An experience level of 6 out of 10 and an overall average of 7.3 compared with the group’s average of 9.0 may explain any diminish within all test procedures.
Mental Skills Questionnaire Results
(Subject 6 Group B)
Table 4.3.2 Mental Skills Questionnaire Results (Subject 6 Group B)
4.3.3 Group C – Subject 5
Figure 4.3.3 Subject 5’s Questionnaire Results
Subject 5 (Age= 19, Bowler) within group C produced an improvement within test scores. (PT= 6, 1st = 10, 2nd= 10). With only an experience level of 5 compared with the average of 6.5, it shows a positive correlation for a subject with low self-confidence and concentration. An imagery score of 75% is deemed to be high, although relaxation is a key factor of mental preparation of which subject 5’s scored a low percentage of 54. Overall it has been seen with a relatively high imagery score, results will have an impact of progression throughout the test procedures.

As displayed above, a major factor influencing test average scores is seen to be the imagery questionnaire results. Subjects 4 (IS= 96, AS=69), 11 (IS= 92, AS=74), and 18 (IS= 88, AS=67), all from separate groups have presented both high imagery scores and high average test scores. On the other hand subject 6’s imagery score P=50, correlates to the average test score of P= 37, being the lowest subject within all groups. The average imagery score for all 18 subjects is 76.5% with a total of nine subjects all showing below average scores. One major factor concerning a majority of the imagery subjects was anxiety and worry. (P= 61.8%) Every individual factor has an influence upon a subjects overall performance. If a subjects motivation and concentration scores are low, this will have a knock on effect upon test results and the overall utilisation on imagery itself. Pearson Correlation Confirms this influences upon one another within appendix D.
4.5 Ability level Analysis
Through all 18 subjects, four are currently county standard and are given a 10 out of 10 score on ability. The overall average came to 6.5 with only 6 subjects being above average. The highest score obtain was through subject 11 within group B (NI) and only a 6 for ability level.
Table 4.5 County players average test scores.
Within the table four county standard players are displayed with the average test score shown as well. Two county players are within group A and the other two are in group C. An average of only 51% for county standard internal subjects against an average of 65% for county standard external subjects shows a correlation with the rest of the group’s scores. The overall group mean equalled 51.6%, meaning all bar one of the top players produced scores above average.
4.5.1 County Standard Vs None County Standard
Figure 4.5.1- County players average test scores against the none County subjects
As seen from the graph, four none county standard players exceeded over the County standard average. Subjects, 4 (TSA = 69), 8 (TSA= 66), 11 (TSA= 74) and 18 (TSA= 67) all produced high scores throughout the duration on the test procedure. Subject 11 noted the highest individual even being within group B (NI) and with a batting ability of only 6. Subject 8 also had an ability of 6 while subject 4 and 18 had an ability of 7 and 9 respectively. There does seem to be a slight correlation between batting ability and test average scores, although four of the subjects listed above contradicted the theory. Additional data relating to Pearsons correlation can be found within appendix H.
4.6 Concentration Ability: County Standard Vs None County Standard
Figure 4.6 County player’s concentration ability Vs none County players
As the graph illustrates the County standard players are highlighted in black with the rest of the subjects displayed in blue. Subjects 1,5,13 and 14 contributed to the County group with scores of 92, 54, 92 and 66 producing a mean of 76, while none county players generated a mean of 62.6 although there are larger number of subjects throughout the group. Overall the Figure 6.10 and 6.11 demonstrate a correlation between concentration levels and overall test score averages. For example subject 13’s concentration level totalled to 92 while influencing the test score of 63 from an average of 51.7.
4.7 Summary of Results
Through the testing procedure the study has collected numerous results relating to the study’s overall objectives. The findings towards analysing the most effective imagery perspective came through the testing procedures: pre test, 1st test and the 2nd test. The results discovered that the two imagery groups had a slightly better improvement rate than group B. The most positive performance was by subject 5 within group A with over a 100% improvement from the first pre test. The findings also showed no significance difference between external scores and internal scores, Group A (M=11.083), Group C (M=11.167).
When analysing data upon County standard players against none County standard players, there does seem to be a slight correlation, although subject 1 in group A scored a below average score in the entire test while subject 11 (NI) produced the highest score with no imagery involved.
Overall groups A (IN) and C (EX) produced higher average test mean scores than group B (NI), as shown in Figure 6.4. This may be due to a number of factors including, batting ability or age, although the highest scoring subject was from group B (NI) with a batting ability of 6. The data collocated has very much complimented many studies throughout the area, but also some aspects of the study have contradicted previous studies through mental imagery. Through the next section the study will analysis the data findings with relation to past research to see any contribution, contradiction or even complementation.
5.0 Discussion
5.1 Introduction
A discussion is a body of text that aims to analyse the final findings to produce propositions and justifications for the study’s outcomes with relation to previous sport psychologists’ theories and experiments.
“The Discussion chapter is an opportunity to move beyond the data and integrate, creatively, the results of the study with existing theory and research” (Rudestam.K & Newton.R, 2001, p167)
Through this chapter, the three main objectives will be analysed intensively with specific reference to past research. The objectives are as follows:
- Establish which imagery perspective is the most effective through a series of cricket related tests.
- Find out if there is any correlation between the effectiveness of the imagery perspectives among County standard cricket players against none County Standard with external influences.
- To discover if imagery training is more beneficial than non-imagery training and establish if the test results and findings complement or contradict previous studies within the area.
The aim of the study was to assess the effectiveness of external and internal imagery among University cricket players during a number of batting ability tests. The results of the analysis of variance (ANOVA), demonstrated no significant difference between all three test groups. (F=0.65, P= 0.938). Through this next section, the objectives will be analysed intensively with relation to previous author’s research.
5.2 Analysis Objective 1
Objective one stated, “To establish which imagery perspective is the most effective through a series of cricket related tests”. Through this objective, the study was determining if internal imagery was more effective than external. The average test results showed a slight difference (9.3 vs. 9.5) in favour of external subjects while the ANOVA analysis displayed no significant difference between both perspectives. (F=0.23, P=0.882) The F-prob is the probability that the differences are due to chance.
Therefore, while test performances increased through all three test procedures, the expected dominance of one imagery perspective was not established.
Sandy, Allen & Weinberg’s (1994) study on ‘The Effect of internal and external imagery on cricket performance’ between 64 subjects also concluded no significant difference between either imagery perspectives. These results seem to complement the current findings as well those of Skelham.M (2006) during a study on ‘the effect of imagery an amateur cricketers during a bowling accuracy test’ in which he stated that the lack of significant results might be due to the short period of time provided for the subjects to perform the imagery training. However, other studies have contradicted the current findings, for example Elton (1994) has described internal imagery as the only effective method within mental imagery to enhance an athlete’s performance. This is also backed up by Jeannerod (1994) and Smyth et al (1998) explaining that internal imagery is the superior perspective due to its production of more neuromuscular activity than external imagery. On the other hand while still contradicting the study’s results, Sugarman (2007), Mahoney & Avener, (1977) and Rotella et al, (1980) all agree that external imagery is more successful in improving performance than internal. The perspective allows the cricketers to gain quality feedback to ensure an improvement throughout training. (Weinburg & Gould, 1995) This quality of external imagery is reiterated by subject 1 within group C (EX) during a focussed interview which can be found in appendix K. The subject states that, he uses both types of imagery and finds them both as effective in different situations. Cheadle (2002) explains, external imagery is more effective for the acquisition of skills that rely on form for their execution, while Orlick & Partington (1986) make clear that internal imagery is generally used by top athletes and external is more suitable for non-elite athletes. (Mahoney, Avener, 1977)
From this statement, subject 5 (IN), a County standard cricketer, declared he used internal imagery the most while training, while subject 1 (EX) also a County standard batsman’ explains both types of imagery are used in different situations. Gordon, Weinberg & Jack (1994) also contribute to subject 1’s (EX) comments by explaining, athletes will tend to switch the type of imagery depending on the type of task and difficulty. The results from the interview indicated that most of the subjects only used imagery in conjunction with training rather than competition.
Past research and experiments suggest the effect of mental imagery has yielded indecisive results. The current findings revealed that, the two imagery groups (EX) & (IN) showed a greater improvement level than group B (NI) but proved no significance between the two separate perspectives. Salmon & Hall (1994) also found the same results when they carried out an investigation on ‘The use of imagery by soccer players’ among national, provincial and local level athletes. The participants were also split up into a control internal and external group. The subjects undertook six one hour training sessions per a week for a total of six weeks. The results showed no difference in the imagery perspectives, however the elite performers reported to use imagery more than non-elite athletes. Many authors have tried to differentiate between each perspective and the effectiveness of each one, but no one has concluded a set of reliable results to distinguish one consistent theory.
5.2.1 Summary of Objective 1
The results from the study reported no significant differences between the internal group (IN) and the external imagery group (EX). When relating these results to past authors’ research, the results complement one another. However not all the authors agree, and there might be key factors which determine the reliability of the outcome.
The timescale of the test procedure is a key element in ensuring consistent results throughout each subject. Weinberg (1995) suggests the practice sessions should only last 10 minutes through a six day training week due to participant’s attention and concentration span. Also the length of the whole test should start at the beginning of a season and conclude during the end of the season. (Murphy, 1990). Overall the results gathered have provided additional confirmation of the uncertain and inconclusive nature of results provided by past researchers.
5.3 Analysis Objective 2
Objective two stated, “To find out if there is any correlation between the effectiveness of the imagery perspectives among County standard cricket players against none County Standard with external influences”. To discover the outcome of objective 2, each subject wrote down their own perceived batting ability from one to ten, ten being County Standard. Overall the study included four County standard batsmen (CSB) with a mean age of 20.75. All four County standard players were split up equally into the two internal (IN) and external (EX) imagery groups. The CSB scored an average test of 58, while non CSB produced a mean of 49.8, concluding a better performance by the more experienced sector. (Related information found within appendix H)
These results are accepted by Weinberg and Gould (1999) as they agree that experience level is a major influence on the effectiveness of mental imagery. Feltz and Lenders, (1983) also produced similar findings when conducting an experiment on the ‘Effects of mental practice on motor skill learning and performance: A meta-analysis’. Feltz and Lenders (1983) also discovered that mental imagery benefits elite athletes more than non-elite. However, Clack (1960) and Corbin (1967) feel that novice athletes will utilise the imagery method greater than experienced players. It is claimed imagery is at its optimal effectiveness during the early stages of learning. (Driskell et al, 1994).
All the authors have stated contradictory and complementary views towards the studies end results, although Weinberg and Gould (1999) provide the final understanding, explaining novice performers benefit from imagery during the learning of cognitive elements, whereas experienced athletes utilise imagery more during refined skill training. The ‘Cover Drive’ shot test throughout the study is recognised as a refined skill which may explain the improving results from the County Standard Batsmen. The correlations and results on County Standard Players are described in appendix H.
The mental skills questionnaire results seemed to provide a correlation of imagery ability and test score averages. As seen in Figure 6.5, subject 5’s imagery score proved to be one of the highest with all subjects. The CSB’s mean imagery ability totaled to 81.25 whereas non-County standard players produced a mean of 75.1.
Imagery ability is judged as the most powerful factor when influencing the effectiveness of imagery upon an athlete. Issac (1992) confirms the current findings by explaining that imagery is more effective when participants have a higher ability to imagine. During a study by Murphy (1994) he illustrates the main factor of distinguishing between novice and elite performers is the imagery ability as well. The current test results clearly complement this theory which is further backed up with subject 4’s (IN) imagery ability and test scores. (IA=96 TSA=69). However there do seem to be exceptions to this rule as subject 15 within group C (EX) produced a relatively high imagery ability but a low test score average. (IA=71 TSA=42).
Another key factor influencing test average scores among CSB and non-CSB is seen to be the concentration ability within each subject. As the results are shown through figure 6.11, numerous authors have firmly established that athlete’s concentration ability has a decisive impact on the overall performance of learning specific skills. (Wulf, Landers, Mercer and Tonner, 2004).
Cashmore (2002) adds further explanation to this theory by stating:
“Usually, the more adept athletes become at their sport, the more able they are to concentrate efficiently” (Cashmore, 2002, p70)
This presumption is clearly justified through the study with County standard batsmen having an overall concentration ability average above the rest of the subjects. The mean concentration ability for CSB = 76 compared with non-CSB= 62.6. The average test scores reflect these results and demonstrate the effectiveness of concentration ability upon performances. After the post test interviews, subject 15 (scoring a 42% in the test and with 41 concentration ability) explained how distractions around him caused a lack of concentration at times. Subject 15 goes on to say that he believes imagery is an effective method of enhancing performance although some people will benefit from it more than others. (Appendix J)
5.3.1 Summary of Objective 2
The results from the study concluded a correlation between concentration abilities and average test scores. The County standard batsmen proved their concentration and imagery levels had an impact upon performance scores. These results are complemented by numerous authors explaining that experience, imagery ability and concentration have a positive impact on scores. One factor which may have determined the results is the uneven numbers with County players and non-County players. An even distribution may have obtained more accurate results although it is clear County players perform at a higher level due to their experience throughout the game.
5.4 Analysis Objective 3
Objective three stated, “To discover if imagery training is more beneficial than none imagery training and establish if the test results and findings complement or contradict previous studies within the area”. Throughout the investigation of objective three the main comparisons were through test scores from group B (NI) against groups A (IN) and C (EX). All three tests produced an average score of 8.9 for group B (NI) and 9.4 for groups A (IN) and C (EX), although no County standard players were present within group B (NI). (Results shown on figure 6.4- Overall Mean Imagery Group’s Test Scores).
Previous studies have strongly agreed that imagery training is far more beneficial than no imagery training at all. Martin, Moritz & Hall, (1999) used imagery within a variety of tests on a selection of sports. The results revealed that imagery was used effectively through each sport and contributed to each participant’s overall performance score.
Other authors have further complemented the study’s results in 2002. Cumming, Shambrook & Hall (2002) conducted an experiment that revealed the influence of mental imagery. The competitive level of each individual was proved to be the main factor on the performance of imagery. However, Subject 11 (NI) with a batting ability of 6 produced the highest scores out of any participant involved, (TSA= 74) contradicted studies from Jordet, (2005) using a field goal kicker through imagery training. The results indicated a positive impact on performance and confirmed a difference between non-imagery training and both internal and external training. The experiment was multiple baseline, with a small sample of subjects over a long period which could validate the outcome, although it doesn’t say if the subjects were elite or non-elite performers. Even though it seems imagery is far more effective than none, not all authors have agreed with this theory. Corbin (1972) has suggested that research through the subject area has revealed inconclusive evidence. Corbin explains that the variety of tests through different sports cannot provide reliable findings to establish a decisive conclusion. Martens (1987) also agrees with this statement when explaining the unknown effectiveness of imagery when an individual is learning a certain skill. It only seems Feltz and Landers (1983) have produced the most dependable findings concluding mental imagery effects are primarily associated with the cognitive-symbolic rather than the motor elements of a task. (Gill, 2000)
Overall it has been proven that mental imagery is far more effective than no imagery at all, but there are some determining factors that let imagery work effectively upon each individual. The relationship between imagery ability and test scores showed a correlation between numerous subjects, but it is possible that the relationship between these variables is not that simple.
The Psychoneuromuscular Theory (Carpenter, 1894) describes the imagery process as when movements activate the brain into thought process. The electrical activity in the brain is closely connected to the kinaesthetic aspect of imagery, meaning the majority of group A (IN) were processing through the psychoneuromuscular theory. The process is thought to be more effective for elite performers, which is justified with subjects 4 and 5 scoring the highest test average out of the internal group. (TSA= 69 & 56). The process imagines the next movement within a skill before it is performed. A variety of studies have analysed this theory, with Cox (2002) explaining that psychoneuromuscular theory is the most reliable theory of how the imagery process works, however Cashmore (2000) believes there is weak evidence to support this theory.
Another method strongly involved within the imagery process is described as the symbolic learning theory Sackett (1934). The theory holds opposing views to the Carpenters psychoneuromuscular theory as the electrical activity is not vital (Cox, 2002). The process is more related to the external and novice performers as they are imagining from an outside perspective with error correction in mind. The theory suggests advance performers don’t utilise the method as well as novice athletes. This is thought to be due to advanced performers feeling the movements coming naturally into their brain as they have practised the skill before. The theory complements the results as all the novice batsmen within group C (EX) showed improvement from the Pre-test, although Cashmore (2000) once again concludes that there is insufficient evidence to suggest the theory is correct.
Overall each participant will use imagery in different methods. If an external user has been selected to perform internal imagery throughout the test, it is not going to be ensured that the subject will use their least preferred method.
5.4.1 Objective 3 Summary
The results from the study concluded both imagery groups produced higher overall improvement scores although each imagery group did have two County players. However the overall improvement justified the third objective with complementary studies from a variety of authors within the area. Each participant will use imagery in their own personal method although we do know that elite performers will benefit from imagery more than the novice performers.
5.5 Discussion Summary
The study’s objectives have concluded complementary and contradictory results when set against past sport physiologists’ research. The results on objective one suggested there is no significant difference between the internal and external imagery perspectives, although external test scores proved slightly higher. The results seem to agree with the majority of authors, however Jeannerod (1994) and Smyth et al (1998) explain that internal imagery is only seen as the more effective. The final findings suggest different experience levels will determine which imagery perspective is beneficial for the participant.
Through objective two, the findings proposed County players found imagery more effective than non-county players. These results were agreed by the majority of authors with Feltz and Lenders (1983) acknowledging that mental imagery benefits elite athletes more than non-elite. Experience level was found not to be the only determining factor. The concentration levels clearly showed correlation between test scores through the County standard players.
Objective three shows the impact of mental imagery compared with group B’s (NI) overall improvement. The two imagery groups showed constant improvement throughout, however only one subject from group B (NI) showed any improvement at all. Overall the three objectives of the study have been fully examined using internal and external imagery techniques. The results showed a variety of external factors which can influence the effectiveness of imagery upon a University cricket squad. The final chapter will discuss the final outcomes of the study and analyse the techniques and methods used throughout the investigation.
6.0 Conclusion
6.1 Introduction
A conclusion is a body of text which evaluates the accomplishment of the objectives throughout the duration of the study. The chapter will refer back to the introduction and provide a critical analysis on the studies overall methods of investigation. The development of the study will be examined with future research in particular reference.
The results from the investigation concluded imagery training an effective method to mentally prepare athletes before competition. The differences in age, ability, concentration or self-confidence may have a slight influence on the success of the training, although the results have shown improvement for the majority of imagery subjects.
The increasing participation rates throughout the game will create a more competitive environment making professional athletes and coaches find additional techniques to increase the standard of performance. The information on mental preparation methods has been analysed intensively for years and Feltz and Landers (1983) realised that mental rehearsal provides numerous benefits towards physical performance. Many authors have complemented these theories although some authors haven’t. The contribution of the studies results will be analysed through the three main objectives below, with reference to past research to show clarification towards previous theories within the area.
6.2 Evaluation of Objective 1
The results on the current study showed how valuable imagery training is upon young cricketers and proved more consistency and reliability evaluations throughout the area. These results have provided extra support towards Sandy, Jackson & Weinberg (1994) and Skelham.M (2006) investigations within the effectiveness of imagery upon cricket players. The current results showed a slight improvement difference in favour of the external group, however, when under ANOVA analysis the results showed no significant difference. These results have been seen to be a common occurrence when internal imagery is compared with external imagery. Gordon, Weinberg & Jackson (1994) and Hall et al, also found no significant differences between each perspective, although it was established that athletes are able to switch between each type depending on the task. On the other hand Elton (1994) finds internal imagery more effective while Sugarman (2007) describes external imagery as the only effective tool when using it for error correction. These contradicting results reveal the inconclusiveness evidence provided through the area. Each previous study has used different size samples, different experience levels and different age ranges which may explain why each author is experiencing contrasting results.
6.3 Evaluation of Objective 2
The results on the current study proved how experience level can have an influence on the effectiveness of imagery. All four County players experienced an improvement in performance which demonstrated a strong correlation between the two variables. These current results are seen to compliment Weinberg and Gould’s (1999) conclusions that experience level is a major influence on the effectiveness of mental imagery. Two of the most well- known sport psychologist, Feltz and Lenders (1983), also have agreed with this theory by adding, the elite performers will experience the full impact of mental imagery more than the novice performers. On the other hand Clack (1960) and Corbin (1967) feel that novice athletes will utilise imagery greater than experienced players. Overall Weinberg & Gould (1999) produce the final understanding by explaining, imagery will benefit novice performers during leaning of cognitive elements whereas experienced performers utilise imagery more during refined skill training.
6.4 Evaluation of Objective 3
The results on the current study show how effective imagery training is among University cricket players. Corbin (1972) & Martens (1987) have always suggested that imagery studies have always concluded indecisive results due to the uncertainty of different individual characteristics. However, many years have past since 1987 and numerous authors have established that mental imagery techniques are far more effective than no imagery training at all. Every individual will not experience the same effect, however it is known when imagery is done properly an athlete’s performance will be enhanced. These current results are seen to compliment Martin, Moritz & Hall (1999) studies through a variety of sports, although it is unknown the size of the sample or if the participants were elite or novice performers. The examination of mental imagery perspectives will be ongoing, until a dependable sport psychologist produces a set of trustworthy results.
6.5 Overall Evaluation
From the current studies results of mental imagery, it can only be said that it’s shown positive results for mental preparation techniques. The study has helped educate numerous cricketers on the advantages of using mental imagery which has helped the participants to enhance their performance through a particular skill.
Overall, whilst it is known that the mental side of cricket is 90% of the game, professional athletes and coaches will continue to use mental imagery as a method of preparation prior to competition. The investigation of Internal Versus External Imagery has concluded many indecisive results through numerous authors. Some authors claim Internal Imagery is far more beneficial than External Imagery, and then others claim the opposite. Imagery can benefit both novice and elite performers, although maybe not in the same situation. Internal imagery has been said to help aid the novice performers, while external imagery seems to benefit the elite performers within a group. Many other external factors contribute towards the effectiveness of mental imagery which include: concentration, imagery ability and anxiety. Through the results it is seen, if a subject has high levels of concentration and imagery abilities, this will have a knock on affect towards the individuals overall performance. Overall this form of mental rehearsal will be continually examined until a set of consistent and reliable results are established within the area.
7.0 Recommendations
Through this section the study will recommend what can be done to improve the accuracy and reliability of results:
- An increase of sample size would be beneficial for the results. The current sample size of 18 was quite short, especially when the subjects are split into three groups. If the sample size is increased through all three testing groups, then the results would prove to be more dependable and data analysing would show more accuracy.
- The testing time of only six weeks may be another factor which could have influenced the results. An individual’s performance needs to be assessed throughout the year with imagery training done every session.
- The ability level of the sample size may have also determined the outcome of the study. Only four County players were involved, with none being in group B (NI). An equal amount of ability throughout all the groups may have produced different outcomes.
- The testing procedure was brand new and had never been used before. This could suggest the method of experimentation may not have provided accurate outcomes and reflected the individual’s true ability.

Internal Imagery
Introduction
Imagery for a cover drive shot
“Imagine that the Umpire is calling the bowlers action type. You are waiting on the crease. You can see with your own eyes and smell the freshly cut grass. You look down at your feet and check your stance. You glance around the ground towards the fielders, looking for gaps as you take time to adjust your pads and helmet. The Umpire signals ‘Play’ as you raise your bat and focus towards the bowler. The bowler pitches the ball in as you adjust yourself. The ball is full and towards the offside as you plant your foot towards the predicted area. You grip the bat and begin your backswing as you watch the ball rotate and travel towards you. You keep your head still and over the pitch of the ball as you strike it with an open the face bat. You feel completely immersed as the ball fly’s off with the sound of ball to bat. The ball finds a gap through the covers as you powerfully push off towards the other wicket………………………………………………………………….”

Introduction
Imagery for a cover drive shot
“Imagine that the Umpire is calling the bowlers action type. You can see yourself standing on the crease. It is like you are watching yourself on TV. The bowler is walking back to his mark as you are adjusting your pads and helmet. The Umpire commands ‘Play’ and the bowler starts his run up. You lift up your bat as all the fielders begin the walk in. The bowler is charging in as he plants his foot on the crease. The ball is thrown down. You will be completely immersed. All you can see of yourself is your head down and your front foot ready to plant next to the ball.
You realise the ball is pitched very full and you re-adjust to play the ball through the square point position. You slightly open the face of the bat and strike the ball with total balance and control. The ball is sweetly struck on the middle of the bat as it fly’s off with velocity and precision. You see the ball find a gap in the field and you set off to run……………………………………….”
