Perseveration as a function of degree of learning and percentage of reinforcement in card sorting.

Abstract

"An experiment relating perseveration to percentage of reinforcement and degree of learning was performed using a modified form of the Wisconsin Card Sorting Test. The results showed that there was a significant interaction between these two variables . . . These results were discussed in terms of the similarity of the pattern of reinforcement during the acquisition stage and the nonreinforcement of the same response during the extinction stage. Supposedly, similarity leads to generalization and thus, slower extinction (greater perseveration)." (PsycINFO Database Record (c) 2006 APA, all rights reserved)
