Abstract

Hooded rats were trained to choose the larger of two circles in order to obtain a liquid reward. Recipients of brain extract from these trained donors showed a significant preference for an even larger circle when given a nonreinforced test for several days after the injection of extract. The substrate for relational learning may be biochemically transferred.
