title: Single-trial free recall from temporal search sets in long-term memory.
abstract: The notion that the primacy effect, which is found in single-trial free-recall experiments, is partly a function of a selective-search component (Shiffrin, 1970) is contingent upon the ability of subjects to retrieve information via a distinctive temporal cue. The beginning of a list may be such a cue which defines a restricted temporal search set within a list as a whole. To test this theory, a second list-half primacy effect was generated in some 26 "unrelated" words lists by associating one color with each word in the first list half and another color with each word in the second list half. As predicted by the two-process theory, retrieval of the words which were presented around the color shift was differentially facilitated as measured by the difference between the probabilities of recall and recognition at each serial position and as compared to that of lists where the color codes were randomly presented.
