Experiments show that when participants are presented with a list of words, they tend to remember the first few and last few words and are more likely to forget those in the middle of the list. Two storage mechanisms in free recall. This is referred as a asymptote.
These participants had to count backwards in threes the Brown-Peterson techniquewhich prevented rehearsal and caused the recency effect to disappear. The tendency to recall earlier words is called the primacy effect; the tendency to recall the later words is called the recency effect.
Saul McLeodpublished Journal of Verbal Learning and Verbal Behavior5 4 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.
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.
Serial Position Effect
A proposed system and its control processes. He found that the probability of recalling any word depended on its position in the list its serial position. Both groups could free recall the words in any order.
Delaying recall by 30 seconds prevented the recency effect. Murdock asked participants to learn a list of words glajzer varied in length from 10 to 40 words and free recall them. One group recalled the words immediately after presentation, while the other group recalled the words after waiting 30 seconds.

The serial position effect of free recall. Words from the end of the list went into short term memory recency effect which can typically hold about 7 items. 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. The psychology of learning and motivation Volume 2.
STM Capacity: Glanzer & Cunitz ()
This is known as the serial position effect. 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 recency effect exists even when the list is lengthened to 40 words. Journal of Experimental Psychology64 5— The words at the end of the list are only remembered if recalled first and tested immediately.
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. Glanzer and Cunitz presented two groups of participants with the same list of words.
Each word was presented for one to two seconds.
