Abstract

The present experiment was conducted to investigate the effects of varying degrees of task consistency on the performance and maintenance of skill in a semanticcategory visual search task. Four groups of participants first received 6000 trials of consistent mapping (CM) training on two different categories. The participants then performed 4000 trials in which one of the previously trained categories remained 100% consistent, whereas the other previously trained category became either 100%, 67%, 50%, or 33% consistent. This second phase of the experiment allowed for the examination of disruption of the search skill as a function of degree of consistency. Subsequent to the degree of consistency manipulation, 100% consistency was restored and participants performed another 4200 CM trials. Results indicate that performance was disrupted by inconsistency and that disruption increased as consistency decreased. On the return of task consistency, performance improved rapidly to predisruption levels, though some performance disruption was evident. Theoretical and practical implications are discussed.
