How interference affects memory recall

Extracts from this document...

Introduction

Introduction Background research Some study's that are similar to the experiment are the Baddeley and hitch (1997), McGeoch and McDonald (1931) and Peterson and Peterson (1959). The Baddeley and Hicth study was a study about rugby players forgetting the names of the teams they had played and that it depended more on the number of teams they had played rather than the amount of time and so the interference of all the different teams they had played had caused them to forget. McGeoch and McDonalds study showed interference of using different lists of words to remember and to recall. The participants had to learn various list of words with various types of list to learn for ten minutes afterwards. Recall of the original words was then tested and the participants that were given a second list of words with similar meaning to the first recalled less than those given unrelated words or nonsense syllables, the participants given no second list of words to recall had the best memory recall. The third study that is similar to the experiment is the Peterson and Peterson (1959) In this study participants were asked remember a single nonsense trigram then had an interpolated task to stop them from rehearsing the trigram such as counting backwards in three's from one hundred. ...read more.

For the second group of participants they will also have the same controls as the group one, and they will have the same song to listen to as there interference for the same amount of time. Ethics The experiment had participants consent and so was aware they were in an experiment. The participants are also allowed to withdraw at ant time during the experiment if they wish to. Results Table of results of words recalled on average Interference Non interference Mean of words recalled 6.8 11.9 Median of words recalled 7 12 Mode of words recalled 7 12 Range of words recalled 6 12 Table commentary Participants who had no interference recalled a mean of 11.9 words this is higher compared to participants that had interference which recalled a mean of just 6.8 words participants with no interference recalled higher than participants with interference in all of the measurements, the mean, median, and mode. The median and mode in both situations of the non interference group and the interference group are both always the same e.g non interference has 12 for median and mode and in interference the recall is 7 for median and mode. Therefore interference seems to lower recall. ...read more.

Conclusion

Genralisation of Findings I can genralise to my target population that I tested as I used 20 participants that were randomly selected and have different backgrounds. But I cannot genralise outside my target population as the age group was only of 16-17yrs old and so wasn't a very wide range of age. And as these students are in a school there brain is much more active than someone who is over 60 perhaps and so results would differ. Application of study to every day life My study can relate to every day life as every day we are using our memory especially in my study as I was focused in a school where participants are constantly using there memory recall to remember things they have learnt recently and so if the participants have just came out of a lesson and decide they wanted to listen to music then this would have an affect of there memory recall on what they have just learnt. And so it would be advisable for students not to listen to music whilst revising or straight after as the music will interfere with what they have just been studying and so they are likely not to remember as much as they could potentially without interference of music. ...read more.

  1. SHORT TERM MEMORY

    background theories listed above which help explain the findings of the investigation. The experimenter ensured that participants were treated and explained to clearly and equally. Random sample was used and it is strength of this experiment because its representative of the target population and everyone has an equal chance of being chosen.

  2. An experiment to investigate the effect of interference on memory recall

    There are also theories to explain forgetting. One of which is the interference theory. This theory suggests that other information that we have previously stored or things we experience whilst trying to remember new information, can weaken our ability to store the new information.

  1. Investigate the effects of Imagery on Memory recall: Visual Aid & Memory Recall

    The observed value (new value of U) is greater than the critical value. The probability of these results occurring through chance would have been greater than 5%. In this case, the null hypothesis is accepted and rejects the experimental hypothesis. Calculations and table can be found in the appendices (20 & 21).

  2. Psychology Retrospective Interference coursework

    This means that each participant in each group experiences only one condition of the independent variable, therefore, controlling individual differences is left to chance. However, it was not considered as a significant confounding variable that needed to be eliminated because independent groups design avoids order effects.

  1. Investigating the short-term memory

    in the 2nd condition the standard deviation was high which refers to the mean not being reliable and therefore results being far from it. A less wide spread of data would help us come to more detailed conclusion in which less mistakes would have occurred.

  2. The effect of primacy and recency on recall

    Although Pieters and Bijmolt's study presented evidence to support the primacy/ recency effect, the procedure allowed participants a delay before recall, which makes the results of this experiment less relevant to the study described in previous sections. Also, their study was carried out as a field experiment, which means that

    Bottom up (or stimulus driven) processing, where only one process occurs at one time, called serial processing. And with more research and investigations another theory arouse, top down processing, which suggests that your expectations can actually dominate the stimulus. So you spot spelling mistakes etc.
