Introduction

Investigating the effects of Context-dependent Forgetting Project brief for psychology coursework PB1: Identify the aim of the research and state the experimental/alternative Aim: to investigate recall of words within the same environment, in which they are learnt, and in a different environment. Consequently, we will see if context affects recall. Alternative hypothesis: Participants who carry out recall within the same room as they are learnt, will be more successful than the contrary group. Null hypothesis: There will be no difference in word recall between the two groups. Any difference will do due to chance alone. PB2: Explain why a directional or a non-directional experimental/alternative hypothesis has been selected. (1 mark) A directional hypothesis was chosen, as there is previous research to support the idea that context influences recall of information, for example: the work of Abernathy (1940) and Godden and Baddeley (1975). PB3: Identify the chosen research method (experimental, quasi-experimental, natural experiment, survey, observation, content analysis or correlation research) and, if appropriate, the design used. (1 mark) The chosen research method is a laboratory experiment, enabling control over confounding variables. Additionally, my chosen research design is an independent groups, which prevents any possibility of the 'order effect'. Participants were an opportunist sample. PB4: Identify the advantages and disadvantages of the chosen research method. (2 marks) Advantages: it is easy to replicate, as potential confounding variables are easier to control, compared to other settings. Disadvantages: a laboratory experiment is an artificial setting and significantly different to real-life situations, due to the high levels of control. Demand characteristics can also occur, when participants try to act accordingly to the situation. Although independent measures prevents the 'order effect', finding twice as many participants can be time consuming. PB5: Identify potential sources of bias in the investigation and any possible confounding variables. (2 marks) Potential sources of bias: 1) Results could be affected by communication between participants. ...read more.

The independent variable was the room where recall took place, e.g. either in the same room as where the words were learnt or in a different room. The dependent variable was the amount of words recalled by participants. The controlled confounding variables include the wordlist given to all participants. Wordlists have to be the same for all participants to ensure that the results of the study are not affected by any differences in the wordlists. Furthermore, the task to prevent rehearsal for the two groups had to be constant, as did the noise and temperature within the environment. Consequently, this would make any impact on the results unlikely. Participants: Thirty-two participants were involved altogether, consisting of 16 work colleagues in each condition. Each group was divided equally into eight men and eight women, ensuring that the results were not influenced by any difference in performance between the sexes. Participants' ages ranged from 25 - 45 and were accordingly divided fairly amongst the two test groups. The sampling method was an opportunist sample, whereby selection was based on anyone who was available for testing at the required time. Apparatus/materials: > Consent forms (Appendix A) > Task instructions (Appendix B) > Wordlists (Appendix C) > Crossword puzzles (Appendix D) > A stopwatch > Plain paper & Pencils Procedures: All participants were taken to Room 1, where all equipment had been previously given out. Wordlists were faced down. There were two pencils on each desk and a piece of plain paper. Participants were asked to enter the room, sit down, not to touch any of the equipment on their desk and not to communicate with anyone until told to do so. Instructions were then read to participants and I made sure that all involved fully comprehended what was being asked of them. As soon as participants were ready, they had two minutes to remember as many words as possible from the given wordlist. ...read more.

Conclusion

If a well published and credit worthy reliable research study was carried on this topic, then it would help to raise the profile of this important subject matter and, would be extremely beneficial to the world of education and may instigate a positive change to the testing of students. Conclusion The null hypothesis, which stated that there would be no difference in word recall between the two conditions, but any difference would be due to chance alone, was rejected and the alternative hypothesis was accepted. This supports the fact that any absence of external cues would result in context-dependent forgetting, meaning poorer recall. References Abernathy, E.M.

  1. Memory is an important area of study in Psychology because it underpins our other ...

    In the experiment a certain gender may find it easier to recall a category of words. For example, males may have found it easier to recall 'car types' than females, as generally males have more interest in that area. A positive aspect of the study is that the subjects used

  2. Images are recalled better than words

    The more often an experiment is repeated, with the same results obtained, the more confident we can be that the theory being tested is valid. The experimental method consists of standardised procedures and measures which allow it to be easily repeated.

  1. This study is based on the theory of cue dependent forgetting - more specifically, ...

    Rationale Like Godden and Baddeley, this investigation uses location as a context for recall. The basis for this investigation is Godden and Baddeley's study of divers, which is replicated with the use of a classroom as the environment for learning. Like Godden and Baddeley, an experimental method has been used.

  2. Memory: Rote Rehearsal and Mental Imagery.

    Distractions were avoided by conducting the experiment in a quiet room. All the participants were given the same amounts of time for the learning and distracter tasks, and also the same amount of time for each word pair wheather using imagery or rote rehersal as the memorisation technique.

  1. Cue dependent Forgetting. This experiment investigates Tulvings theory of cue dependent forgetting, with ...

    They are also internal cues, examples include being tired, alert, nausea, or emotional states such as happy, sad, angry...etc (Cox 2001) The other part refers to Context dependent forgetting, also the part being tested in this study, which points to the external circumstances or environment setting during the time of information being encoded or retrieved.

  2. Investigating the short-term memory

    Same target population was used, and a small sample size of participants was used when conducting this experiment, so the experiment cannot be generalised. If the investigation was to be made better for a 2nd attempt it would be given some thought to how different distractions affect memory recall.

  1. Carry out an experiment on participants to investigate proactive interference on memory recall, using ...

    They then signed the participant consent form (Appendix 4) but did not give their name as the experiment was anonymous and it was unnecessary information. RESULTS Raw data - My response/stimulus sheets can be found in Appendix 7. Collated data tables - (Appendix 6) The data collected was a score out of ten.

  2. Evaluate 3 Approaches to treating Mental Disorders: Psychodynamic, Biological and Behavioural Approach.

    However, such maladaptive learning can be treated by changing the environment so that un-learning could take place. Behaviour therapies: These are often used to treat phobias and involve the patient learning to associate their phobic stimulus spider or whatever with relaxation.
