Interference in a Paired-Associate Transfer of Training Paradigm as a Function of Breadth of Categorization

Abstract

It was hypothesized that category width could differentially predict interference in an (A-Br) transfer of training paradigm. Pettigrew's Estimation Questionnaire was the measure of category width. 18 college students were tested in each of the three category-width levels of the experimental group (A-B; A-Br), 9 Ss were tested in each of the three category-width levels of the control group (C-D; A-Br). Broad categorizers had significantly fewer correct responses and significantly more errors of intrusion on the second list than did either the narrow or the medium categorizers. There were no significant differences between narrow and medium categorizers on number of correct responses or errors of intrusion.
