Suppression of running times by olfactory stimuli

Abstract

Thirsty rats running a straight-way for water were exposed to the odor of rats which had received foot-shock, a perfumed spray deodorant, and the essence of cat. Running times of Ss increased when they first encountered each of the odors. The odor of cat was particularly effective in suppressing Ss’ approach. The first encounter with the odors seemed to function as a mild punishment. Control for odors such as those left by rats which have received foot-shock may be important in many experimental situations. © 1968, Psychonomic Journals. All rights reserved.
