Differences Between Stm and Ltm

Q1. Describe two differences between Short term retrospection (STM) and Long term shop (LTM) in term of continuation and capacity (3 marks)

STM has time of 3-18 seconds whereas the duration of LTM memory contribute last anything from a few minutes to a lifetime. The STM theory was supported by Peterson and Petersons Study (1959), which was their Trigram audition. They achieve this evidence by asking the participants to remember a unmarried nonsense syllable of three consonants i.e. KPD. They were then given another travail to do to stop them rehearsing the trigram. Their recollect was tested after 3,6,9,12,15,18 seconds and the call in had to be in correct order to count. They discovered that 80% of participants recalled the trigrams very well after 3 seconds, but this dropped dramatically to 10 % after 18 seconds. The supporting evidence for the duration of LTM was brought about by Ebbinghaus who tested his memory victimization nonsense syllables after delays ranging from 20 minutes to 31 long time by and by and found that a large proportion of the tuition in LTM was lost comparatively quickly, i.e. in the outgrowth hour and thereafter stabilised to a much dilatory rate of loss. Linton used a diary to record at least 2 every twenty-four hour period all the samets from her life each day for 6 years and then she had to aimlessly test her later recall of them.



The results were that there was a much more even and gradual loss of data over time.

STM has a limited storage capacity; whereas the capacity of LTM is impractical to measure therefore it is enormous. Many early researchers such as Ebbinghaus proposed the capacity of STM and Miller (1956) investigated this limited capacity experimentally. The experiment was known as the magical number seven, plus or minus two and he found out that the amount of schooling that could be reserved could be increased by the cover of lump (packaging the information into larger units). However the STM can only retain 7+ or -2 of the chunks. Also chunking can be improved if the...If you want to get a full essay, order it on our website: Orderessay
