Alternative Turning Response of Armadillidium vulgare

Abstract

Armadillium vulgare, terrestrial isopod crustacea, was used for testing Hull's theory of reactive inhibition in spontaneous alternation responses. More than 85 per cent of the subjects were found to alternate their responses in a 3-unit T maze. No difference was observed whether previous turning responses were forced or not. Alternation increased when the distance between the starting point and the choice point decreased. The results supported Hull's interpretation. Japanese with an English abstract.
