'Blocking rehearsal time with an interference task Essay\r'

'The theories of repositing and how much, or how long we send away opinion on things, and why, is a greatly examine area of Psychology as a science. Psychologists have created and recreated numerous tests and interrogation methods in parliamentary law to prove that their particular possibility is correct. There are two main(prenominal) theories of storage: Levels of Processing (L.O.P.) and the Multi-store Model. The L.O.P. approach was pioneered by two psychologist Craik and Lockhart (1972), who believed that the mind go away remember things better if the selective informationrmation is processed on a deeper level, ie. thought about more(prenominal), victorious into account the add up of ‘ deform’ that is draw into process the information authorized. From research they spy that the deeper the processing required the longer and more durable the memory is likely to be. They in addition identified what they believed to be three levels of processing:\r\nSt ructural †What fewthing looks like. Phonetic †What something sounds like. Semantic †What something means. From experiments and tests carried out, they constitute that the deepest level was semantic, and their reason for this, they argued, was beca put on in position to extract the meaning from a word, and to deliberate it’s relevance in a sentence of speech, requires a lot of processing. They indomitable that hearing a word and indeed trying to visualize it besides requires some extensive cognitive processing, except non as much as semantic processing, and the least amount of mental work was required for morphological processing, ie. what the letters look like. A test carried out by Craik and Tulving (1975), ‘Depth of processing and retention of spoken language in episodic memory’ support their hypothesis.\r\nAnother model which is highly regarded as one of the most influential theories of memory is the Multi-store model, in particula r the two-process model, objected and tested by Atkinson and Shiffrin (1968, 1971). Their theory was that information received by the senses is primarily stored in the sensory(a) store for a very diddle period of duration before it is transferred to the victimize circuit limit memory. Atkinson and Shiffrin believed that when the information is in the short term memory (STM), it could either be rehearsed for a certain amount of while and thence stored in the long term memory (LTM), or alternatively lost. stick out 1.1 illustrates the theory in an easier to understand way. possibly this is besides an example of how the L.O.P. theory is blemish as although the diagram is seen to be structural information, it go away probably provoke grueling visual imagery.\r\nAtkinson and Shiffrin believed that ‘chunks’ of information received by the sensory store could be held in the STM for around 20 seconds, but only 5 to 9 (on average) chunks of info target be remembered without dry run. However, if rehearsed the chunks of information can be transferred into the long term memory and more items can be remembered. The theory of the statement loop interests me, so I decided to look further into it and found that psychologists: Brown (1958) and Peterson and Peterson (1959) independently discovered a method for scrutiny the institution of the record loop called the Brown-Peterson technique.\r\nThis basically involves a make of trigrams (three letter words made up of consonants with no immediate meaning ie. BKD, as apposed to WHY) shown to resigns for 20 seconds, rehearsed for 25 seconds and then enter in order by the pillowcase as well as possible. The aforesaid(prenominal) angle of inclination is then shown to another playing area for the alike(p) amount of time, however this time the 25 seconds rehearsal time ordain be disrupt with an kerfuffle undertaking ie. counting rearward in threes from the figure of speech 58. This is the tech nique I will give as a basis of my mini-cognitive research project.\r\nAIM: To test the existence of the rehearsal loop by preventing it from its task with an snag task during the rehearsal time. RATIONALE: I will be re-creating the Brown-Peterson technique for testing the existence of the rehearsal loop, although my claim will use slightly different trigrams, and on the face of it a different primp of people. I’m interested to check whether the results of my study will support the results found by Brown-Peterson or not. I will use a set word disputation for both groups of people studied and I’m expecting the results of my study to support the results of previous tests, thus supporting the theory of existence of the rehearsal loop.\r\ntheory: When asked to recall the list of trigrams in order after a period of 25 seconds rehearsal time, the subject will remember significantly more trigrams if the rehearsal time is not interrupted by an hoo-hah task. NULL HYPOTHE SIS: Subjects taking part in the experiment will not recall a significantly greater number of words whether their rehearsal time is interrupted with an interference task or not. Any residue found is purely down to chance.\r\n regularity: The method I chose to use in order to obtain the clearest and most reliable data was the laboratory experiment. The reason for exploitation this method is to reduce the amount of outdoor(a) and possibly confounding variables which could interfere with the results; also it becomes very easy to repeat the same test over and over without change. I will use the independent groups design to ensure that different participants are utilise for each test in order to avoid the chances that the participants will skew the results done rehearsal.\r\nThe first set of participants will be shown a list of 15 trigrams for 20 seconds, after which time they will be asked to rehearse these for a period of 25 seconds. afterward that time they will then be asked to write out as many as possible in the correct order (if the trigram is BHD then the participant must write BHD, no dog will be given for BDH). The results will then be recorded. The same set of trigrams will then be shown to a different set of participants for the same amount of time. This time however during the 25 seconds rehearsal time, the participants will be asked to perform an interference task, which will be counting backwards in sets of 4 from the number 295. After the 25 seconds, they too will be asked to recall the trigram list and their results will also be recorded.\r\n'
