Discrimination by rats of conspecific odors of reward and nonreward.
The hypothesis that, after receiving reward and nonreward, rats excrete differential odors perceptible to other rats was tested by making the correct turn in a T-maze contingent on discrimination of any such odors. Clear evidence for an "odor of nonreward or frustration" was obtained, and there was the suggestion of a transistory odor after early reward trials.
