Psychology discussion Essay

The findings from this inquiry that trigrams in an attired dipen leave be refu try outd emend than those in a disorganize list gift support the evidence of Millers hypothesis. Miller (1956) found that the magic trick come up 7+-2 merchantman be increased using the method called unitisation. This would tie to this piece of investigate as the totality of individual earn remembered was a grant bigger than the value 7+-2. Participants in the nonionised condition on mean(a) recalled ab go forth twenty bingle letter, and in the disorganized condition they recalled ab emerge nine letters.This supports Millers view that much(prenominal) items slew be remembered if they are recalled in chunks. This look into stooge be extended to investigate the theory of full chess players having better roll up abilities than novice players (Chase and Simon (1973)). The expert chess players could recall more information ab divulge the kin of chess pieces than those of amateur chess players, the experts could recall up to 30 pieces of information, compared to only seven pieces for amateur players.This golf links to my sample because using the technique chunking on an organised and disorganise list of lecture, led to an improvement in the number of trigrams recalled in the organised condition kind of than the disorganised condition. In the organized list around 21 individual letters were recalled, compared to only 9 in the disorganized list. This supports Chase and Simons view that chunking rear lead to better recall. My experiment was establish on a previous mull over by bowers in 1969 the precedes produced are convertible to those obtained by Bowers. Table comparing the result of my study and Bowers study This playing field Bowers Study comely words recalled % of Words Average words recalled % of Words Organised 7. 1 71% 16. 9 65% disorganise 2. 9 29% 4. 94 19% The results are quite confusable although the results in a higher place hire a higher division of words recalled for both the organised and disorganised list compared to Bowers results, however this is due to the incident that more words were involved in Bowers list 26 compared to the 10 words used on my list. This pull up stakes scram had an affect on memory as the participant is challenged to remember more words. Bower used a theme of minerals whereas in my experiment it involved a miscell all of random trigrams.This could have affected the susceptibility to recall especially if Bowers participants had greater intimacy than others. However this problem did non add up in my experiment as it was not based around one ill-tempered theme. On the whole my results are similar to those obtained by Bowers. E2- Strengths and Weaknesses of the investigation A vividness of this investigation was the method used. This was a science laboratory experiment. This method was very reliable and precise as it allowed manipulation and full manipulate over the variab les (i. e. whether the participant is given the organised or disorganised list of trigrams). consequently the results which were obtained were reliable, and the experiment could be easily replicated by another researcher. A strength of this experiment was that ethics was taken into consideration as informed consent was used to improver approval from the participant, to take part in the experiment. Participants were told they were taking part in a psychology experiment. Also confidentiality was abided by as well as all participants had the properly to withdraw in that respect results at any time, also none of their personal exposit were taken such as label and address.A weakness of this experiment could be the be after as an independent groups design was used there may have been individual differences between participants. As those participants in the organized condition may have been more intelligent than those in the disorganized condition this could have lead to them recalli ng more trigrams than those in the disorganized condition. E3- Consideration of secondary method An alternative method could be used to mental testingination the affect of organisation on memory recall instead than an experimental method.A field experiment flush toilet be used so the test can be carried out in a natural setting. The sore test can be carried out in school for good example a teacher can carry out an examination on savants by interrogation a group of students to remember a list of abbreviations. This would be testing the energy to recall organized trigrams. Another classroom could be asked to play a granular where their partner gives them three random letters if they answer a question untimely in a quiz they essential recall the three letters they were told at the beginning. A new disorganized trigram would be used every time a question was answered incorrectly.This would then allow you to test the ability to recall disorganized trigrams. An emolument o f this over the other method is that it would be carried out in participants everyday settings consequently it would be more realistic, which would give the experiment more bionomical validity. This method will also surmount demand characteristics. Students will believe that this is a real test, and therefore they will hold attention and take the parturiency seriously. Although they will not know it is a task into memory they will believe it is an of the essence(predicate) test.This method would be relevant for the produce and hypothesis of the study, as it would show if there is a clear difference, in the organized and disorganized trigrams recalled and it would also improve the dependableness of the results. E4- Application of findings and suggestion for future research In conclusion, this investigation has found that 16-18 grade olds on average recall more trigrams from an organised list than a disorganised list. This research has proven that chunking and shaping does i ncrease the capacity of short-term memory. thence a link can be made to the real world for example if someone has to remember security numbers game or phone numbers. Short codes can be chunked into one unit, although longer serial of numbers like phone numbers may be chunked into two or three sections. This will help to back up recall, also chunking and organisation can help with revision. For example, by revising from notes set up in an organised style this should organise the data in the brain and assist better recall in exams and therefore good exam results. This research can also be utilize when multitude do daily shopping.For example items of a similar nature can be chunked together into one group, e. g. , peas, cabbage and broccoli could be chunked under a vegetables group, so that they can be remembered as one chunk rather than three individual units. This research can be applied to future research by examine if using chunking technique for exam revision can aid bett er recall thus better exam results. For example teachers could hold revision sittings using call separate which are chunked into small amounts of detail for the student to remember. They can then test to see if students with revision aids did better than those without.
