The study of short term memory

Extracts from this document...


Peterson and Peterson (1959) Peterson and Peterson wanted to find out how long memory is stored into the short term memory when there was no rehearsal. Participants were found at a university and were tested with trigrams they were shown three letters e.g. YXB. They were also told a number from that number they had to count backwards in threes. After this test was carried out on the participant they were asked the three letters they were told in the beginning. Peterson and Peterson found out that information stay in the short term memory for only 18 seconds. The results for this experiment were not reliable enough because the participants were university students are different to the general population. The experiment was carried out in a laboratory this does not reflect to the things we do in everyday life. Long-term memory is where the information is stored for a long period of time this could last from a few seconds to a life time everything we know is stored into the LTM. ...read more.


Recognition is when you are given a clue to help u find the memory in your LTM. The pictures used for the yearbook of students did not give permission to the researchers to show the participants this is ethical infringement for the researchers. The participants that were tested might of rehearsed the name of students and tried to memorise the faces of students this could not be reliable because the LTM could have been found because this was regular rehearsal so there results are unreliable. Murdock (1962) Murdock carried out an investigation called the serial position effect. He asked participants to remember a list of words the participants found it easy to remember the first few words ( the primary effect ) and the last few words ( the recency effect ) . The multi store model shows that the words in the beginning of the list were rehearsed and put into the LTM and the words at the end of the list were still in the STM. ...read more.


The working memory holds new information and takes knowledge from the LTM to put with the new information. The memory model holds all the information you are thinking for most psychologists they believe it is your conscious. When we do tasks such as mental arithmetic the working memory is being used. The information in the working memory is fragile and could be easily lost. The central executive controls what happens in the working memory it manages what goes on. The phonological loop is an auditory store it has two parts Phonological Store is known as the inner ear it deals with perception of sounds Articulatory loop this has a link between speech productions also known as the inner voice it has a verbal rehearsal system. Goodman and schaff (1997) Children would not be able to understand adult type questions e.g. the pirate engaged in blowing bubbles during the course of the puppet show is that not true? The child would find this hard to answer. The pirate blew bubbles didn't he? Child would find this easier to answer. Good man and reed found out children at the age of three have better details of an incident then others. ...read more.
