Cognitive aspects of information processing: I. The familiarity of S-R sets and subsets.

Abstract
"The investigation concerned S's ability to reduce his reaction time (RT) on the basis of knowledge that only a small subset of a larger, familiar alphabet would occur as stimuli in a particular experiment. It was predicted that Ss could make effective use of this knowledge only when the smaller subset itself constituted a highly familiar group . . ‥ The results of three experiments were in agreement with the predictions . . ‥ These results support the view that information-handling rate is in part a function of cognitive sets which reflect the preparation which S makes, in advance, for responding to any one of a group of stimuli. Some characteristics of these cognitive sets are discussed, and the notion is related to recent theories of choice behavior."--(29 ref.) (PsycINFO Database Record (c) 2006 APA, all rights reserved)
