Journal of Verbal Learning and Verbal Behavior5 4 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.
Serial Position Effect
The tendency to recall earlier words is called the primacy effect; the tendency to recall the later words is called the recency effect. The psychology of learning and motivation Volume 2.
This is referred as a asymptote.
He found that the probability of recalling any word depended on its position in the list its serial position. This is cuintz as serial position 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.

Journal of Experimental Psychology64 5— Both groups could free recall the words in any order. This lganzer known as the serial position effect. Each word was presented for one to two seconds.
Saul McLeodpublished Murdock suggested that cuniz early in the list were put into long term memory primacy effect because the person has time to rehearse each word acoustically. A proposed system and its control processes. These participants had to count backwards in threes the Brown-Peterson techniquewhich prevented rehearsal and caused the recency effect to disappear.

This recency effect exists even when the list is lengthened to 40 words. Delaying recall by 30 seconds prevented the recency chnitz. Glanzer and Cunitz presented two groups of participants with the same list of words. The words glanzeg the end of the list are only remembered if recalled first and tested immediately. Two storage mechanisms in free recall. Murdock asked participants to learn a list of words that varied in length from 10 to 40 words and free recall them.
Words from the end of the list went into short term memory recency effect which can typically hold about 7 items.
The serial position effect of free recall. One group recalled the words immediately after presentation, while the other group recalled the words after waiting 30 seconds.
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.
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.
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.
