Fan Size and Foil Type in Recognition Memory.
Walls, Richard T.; And Others
An experiment involving 20 graduate and undergraduate students (7 males and 13 females) at West Virginia University (Morgantown) assessed "fan network structures" of recognition memory. A fan in network memory structure occurs when several facts are connected into a single node (concept). The more links from that concept to various discrete facts (the larger the fan), the slower the retrieval time (fan effect). The experimental design of this study, which used a fact retrieval paradigm, was a three-way, mixed design with one between-subjects independent variable (the number of times a conversation was heard by a learner) and two within-subjects independent variables (fan size and type of test statement). Subjects listened either one time or three times to a 2.5-minute conversation between Sherlock Holmes and Doctor Watson that was taped from a radio program. The subjects were tested, using a timing program, for recognition of target probes and three types of foils (within-fan, cross-fan, and outside-story) associated with large versus small fans. Twenty-four test statements were administered. Fan size, type of test statement (target probes and foils or distractors), and number of times heard all had significant effects on recognition memory. There was also evidence that semantic and episodic themes were operating to influence performance. The text of the conversation used in the study is included. A 20-item list of references and three data tables are provided. (TJH)
