The aim of the experiment was to measure the percentage of correct recalling of letters when they appear in a list of ten letters and each letter is presented for one second. Based on a past research done by Murdock (1962) the hypothesizes of this experiment was that the letters that was presented at the beginning of the list will be recalled better that the letters that were presented in the middle of the list and also the letters that was presented at the end of the list will be recalled better than the letters presented the beginning of the list.
Results
The results of the experiment showed that the percentage of recalling for the letters at the beginning of the list were 62% and the percentage of recalling for the litters presented in the middle of the list were 50% and the percentage of recalling for the letters at the end of the list were 65%.
Discussion
As shown in the section above the results of the experiment were as expected and the two hypothesizes of were supported. Based on the previous research that was made by Murdock (1962) about the serial position effect. The expectation were that the letters at the beginning of the list will be remembered better that the letters in the middle of the list and that is because the participants will start to rehearse the letters they see at first and rehearsing the letters can move them from the short term memory to the long term memory to be recalled again when needed (primacy effect). And the other expectation was that the letters at the end of the list will be remembered better than the letters at the beginning of the list and that’s because and that because the participants will keep the letters they saw last in the short term memory and they will remember it better because it the last thing they saw (recency effect). And the loss of the letters in the middle of the list from the memory can be explained by 'displacement' when the last few letters are presented they displace the letters that were..

Serial position curves also typically reveal a recency effect in which the last three or four items in the list are also better recalled than the middle items (e.g., Glanzer & Cunitz, 1966, Exp. 1; Postman & Phillips, 1965). Wiz khalifa started from the bottom mixtape. The serial position effect is defined as “The tendency for items at the beginning and end of a list to be remembered better in immediate free recall than those in the middle.” (Glazner and Cunitz 1966; Postman and Phillips 1965) The Serial Position effect comprises of two parts: The Primacy effect (when words at the start are remembered.

Abstract
Semantic Network Theory
In-immediate free recall, words recalled successively tend to come from nearby serial positions. https://powerfullistings.weebly.com/augusto-pieroni-leggere-la-fotografia-pdf-to-excel.html. M. J. Kahana (1996) documented this effect and showed that this tendency, which the authors refer to as the lag recency effect, is well described by a variant of the search of associative memory (SAM) model (J. G. W. Raaijmakers & R. M. Shiffrin, 1980, 1981). In 2 experiments, participants performed immediate, delayed, and continuous distractor free recall under conditions designed to minimize rehearsal. The lag recency effect, previously observed in immediate free recall, was also observed in delayed and continuous distractor free recall. Although two-store memory models, such as SAM, readily account for the end-of-list recency effect in immediate free recall, and its attenuation in delayed free recall, these models fail to account for the long-term recency effect. By means of analytic simulations, the authors show that both the end of list recency effect and the lag recency effect, across all distractor conditions, can be explained by a single-store model in which context, retrieved with each recalled item, serves as a cue for subsequent recalls. The recency effect refers to the decline in memory performance with the passage of time or the presence of interfering events. Although recency effects in recognition memory are long lived and resistant to interference (e.g., Strong, 1912), recency effects in free and probed recall are short lived and are extremely vulnerable to interference (e.g., Postman & Phillips, 1965). In this article we analyze the recency effect in free recall, focusing on the details of retrieval under various distractor conditions. https://powerfullistings.weebly.com/download-brosur-daftar-sekolah-cdr.html. In free recall, the recency effect is almost completely eliminated by 15 s of a distractor task (Glanzer & Cunitz, 1966; Postman & Phillips, 1965). The special status of the recency effect in free recall is highlighted by findings that numerous experimental manipulations and participant variables have different effects on recency and prerecency items. For example, list length (Murdock, 1962), interitem similarity
