![]() ![]() It is called a free recall task because the subject is free to recall the items in any order that he or she desires. At the end of the presentation of the list, the subject is asked to recall the items (e.g., by writing down as many items from the list as possible). ![]() For example, an experimenter might read a list of 20 words aloud, presenting a new word to the subject every 4 seconds. In a free recall task, a subject is presented a list of to-be-remembered items, one at at time. Glanzer & Cunitz, 1966 Murdock, 1962 Postman & Phillips, 1965). ![]() Though not providing an explanation of serial position effects in free recall.įree recall is a basic paradigm that has long been used to study human memory, and which was central to the verbal learning tradition in early cognitive psychology (e.g. (Revised October 2010).Ĭontextual Variability and Serial Position Effects. Quarterly journal of experimental psychology, 17, 132-138. Short-term temporal changes in free recall. ![]() Journal of Verbal Learning and Verbal Behavior, 5(4), 351-360. 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. 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. 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). They can write these items down in any order, which is why the method is called free recall. 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. ![]()
