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. In this kind of experiment, subjects are presented a list of to-be-remembered items, which could be digits, words, or nonsense syllables.

For instance, a very common method used to study memory was the free recall experiment. (Revised April 2010).Ī variety of different memory tasks have revealed that not all items in a list were equally likely to be remembered. Quarterly journal of experimental psychology, 17, 132-138. Short-term temporal changes in free recall. 'The serial position effect of free recall'. Journal of Verbal Learning and Verbal Behavior, 5(4), 351-360. The behavior of these two effects provided support to the hypothesis that the free recall task called upon both a short-term and a long-term memory. This curve exhibited a recency effect and a primacy effect. This is because the results of a free recall task were typically plotted as a serial position curve. The free recall task is of interest to cognitive science because it provided some of the basic information used to decompose the mental state term 'memory' into simpler subfunctions ('primary memory', 'secondary memory'). 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). In a free recall task, a subject is presented a list of to-be-remembered items, one at at time.įor example, an experimenter might read a list of 20 words aloud, presenting a new word to the subject every 4 seconds. Glanzer & Cunitz, 1966 Murdock, 1962 Postman & Phillips, 1965). The serial position effect of 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. He found that the probability of recalling any word depended on its position in the list (its serial.
