Eight isopods, Porcellio scaber, were trained with water reinforcement to turn in a T-maze to criterion of correct responses. They were then tested through nine reversals of the turning response. An analysis of variance indicated that mean errors to criterion declined significantly over reversals (F = 4.78, d.f. = 9/63, P < .001).
