Abstract
The peak procedure is widely used in the study of interval timing with animals. Multiple timing measures can be derived from peak responding. These measures are typically presented as averages across many trials based on the implicit assumption that peak responding is stable throughout the session. We tested this assumption by examining whether peak responding changed over the course of the session in 45 mice that were trained on a fixed-interval 30-s schedule. All common measures of peak responding, except stop times, changed over the course of the session: start times increased, response rates and spreads decreased, and, although less reliably, peak times also shifted rightward. These results are congruent with a motivational interpretation, whereby increased satiety leads to the observed behavioral signature of within-session modulation of timed anticipatory responding.
