In Exp 1, pigeons were exposed to a fixed-time 30-sec schedule of food or water deliveries with a brightening keylight stimulus signaling time to the unconditioned stimulus/stimuli (UCS) on each trial. Food and water presentations both produced terminal autoshaped keypecking that was similarly distributed in the trial but differed in response topography and persistence. Locomotor interim behavior (LIB) was different in the 2 motivational conditions. With food presentations, it consisted of a "retreat" to the rear of the chamber after UCS termination, followed by "pacing" in the midportion of trials. The water schedule produced very little locomotor activity with no regular distribution in the trial. Exp 2, using a random-time 30-sec schedule, showed that the differences in LIB persisted in the absence of temporal predictability of the UCS and the keypecking terminal response.
