Abstract

The partial-reinforcement extinction effect was demonstrated at 4–5 days of age in the precocial guinea pig and was related to the appearance of this effect at 12–14 days in the altricial rat. We suggest that the maturity of the septohippocampal system at birth in the guinea pig, relative to the immaturity of this system in the rat, is a possible basis for this difference.
