The effects of degree of learning and problem difficulty on perseveration.

Abstract

"This study aimed to determine the relative effects of the level of learning and the difficulty of the problem on perseveration time in rats. The results of Exp. I suggest that PT increases early in practice and is then followed by a decrease with further practice. In Exp. II, PT was found to increase with the difficulty of the problem."
