• Serial Position Effect Test

A variety of different memory tasks have revealed that not all items in a list were equally likely to be remembered. For instance, a very common method used to study memory was the free recall experiment. In this kind of experiment, subjects are presented a list of to-be-remembered items, which could be digits, words, or nonsense syllables. At the end of the list, subjects are given a set period of time (e.g., two minutes) in which they write down as many of the presented items as they recall. They can write these items down in any order, which is why the method is called free recall. While the subject can recall items in any order that he or she pleases, the experimenter generally plots the probability that an item is correctly recalled as a function of its position in the list, producing what is known as a serial position curve (see Figure 5-1). All things being equal, serial position curves routinely demonstrate, regardless of list length, a primacy effect in which the first three or four items in the list are better recalled than the middle items of the list.

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).

Abstract In-immediate free recall, words recalled successively tend to come from nearby serial positions. 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.

Raaijmakers & R. 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.

Serial Position Effect Test

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. 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.
