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