Experiment 1)Murdock (1962) Experiment Procedure Murdock asked participants to learn a list of words that varied in length from 10 to 40 words and free recall them. Each word was presented for one to two seconds. Results He found that the probability of recalling any word depended on its position in the list (its serial position). Words presented either early in the list or at the end were more often recalled, but the ones in the middle were more often forgotten. This is known as serial position effect.
Serial Position Effect Example
The improved recall of words at the beginning of the list is called the primary effect; that at the end of the list, the recency effect. This recency effect exists even when the list is lengthened to 40 words. Serial position effect Conclusion Murdock suggested that words early in the list were put into long term memory (primacy effect) because the person has time to rehearse each word acoustically. Words from the end of the list went into short term memory (recency effect) which can typically hold about 7 items. Words in the middle of the list had been there too long to be held in short term memory (STM) (due to displacement) and not long enough to be put into long term memory (LTM). This is referred as a asymptote.
The Recency Effect
In a nutshell, when participants remember primary and recent information, it is thought that they are recalling information from two separate stores (STM and LTM)./p Explanation The reason for serial Position effect? A widely accepted reason is that if recall happens immediately the items are still in STM and the first items are in LTM. The items in the middle are presented too late to be rehearsed.

Word list Procedure Glanzer and Cunitz presented two groups of participants with the same list of words. One group recalled the words immediately after presentation, while the other group recalled the words after waiting 30 seconds. These participants had to count backwards in threes (the Brown-Peterson technique), which prevented rehearsal and caused the recency effect to disappear. Both groups could free recall the words in any order. Results The words at the end of the list are only remembered if recalled first and tested immediately. Delaying recall by 30 seconds prevented the recency effect.

Then fill the rows with participants. Everyone has 2 minutes(30 seconds to read their list and 30 seconds to right) to affirm(read out the list of words describing themselves) the person in front of them. After 2 minutes all participants must move to the left on seat. This continues until the limit of either time is reached or till participant met their starting partner. “Speed Dating” modified.
