DETECTION AND CRITERION CHANGE ASSOCIATED WITH DIFFERENT TEST CONTEXTS IN RECOGNITION MEMORY

Three groups of physics Ss and three groups of arts Ss viewed 20 physics words (PWs) and 20 common words (CWs) in a randomly ordered inspection sequence. Ss were then assigned to one of three recognition test conditions where the inspection items were embedded in different sequences of 120 additional words (60 PWs + 60 CWs; 100 PWs + 20 CWs, 20 pWs + 100 CWs). Signal-detection and Luce analyses examined the effects of the different test contexts on Ss′ true sensitivity and response bias. While all Ss found detection of PWs easier than CWs, these judgments varied according to the properties of the recognition sequences. This latter finding was interpreted as indicating that Ss adopted a conservative and probabilistic strategy for the recognition task as a whole rather than utilizing different strategies for PWs and the CWs where these would result in superior overall performance. © 1969 Psychonomic Society, Inc.
