Presented successive stimuli to 63 undergraduates who had to make a binary choice response classifying each stimulus. Each such response was followed by a rating which indicated S's confidence in the correctness of that choice response. Confidence in the correctness of a choice response which followed a correct response (AC) was greater than confidence in a response which followed an error. Confidence in the correctness of choice responses increased over presolution trials but this increase was only found for successive AC trials; ratings sharply decreased over a run of errors. Confidence in the correctness of responses increased in a curvilinear manner during the solution state. Results are interpreted with reference to a hypothesis-testing formulation of concept identification. (PsycINFO Database Record (c) 2006 APA, all rights reserved).
