Using albino rats and a right-angle cross runway apparatus, it was possible to independently vary place and turn by alternating starting boxes at extreme ends of one arm of the cross in massed or staggered order. Animals were rewarded for all choices. Results indicated that alternation of place occurred above chance level when the starting position was shifted in the counter-balanced order, but that alternation of turn remained at a chance level. The results are interpreted as not confirmatory of the prediction from a reactive inhibition hypothesis, but supportive of an exploratory-tendency hypothesis.
