Abstract

Thirty-six college subjects who had taken a memory test from the Wechsler series were chosen from an introductory psychology class and divided into three memory levels (high, medium, and low). Twelve subjects from each of the memory groups were required to categorized geometrical stimulus patterns into positive and negative instances according to an unknown conceptual rule that prescribed a relationship between two known attributes. Each subject was assigned to one of three postfeedback delay intervals of 1.5, 20, or 30 seconds. Performance among the three memory levels was not statistically different even though differences from best to worst were apparent for high, medium, and low memory subjects, respectively. Analyses of variance for both trials and errors to criterion demonstrated a statistically significant postfeedback delay effect on performance. Specifically, a significant difference was found between the shortest and longest delay for all three memory groups. Performance continued to improve as the postfeedback delay was extended to 30 seconds.
