Responding in the peak procedure has long been utilized as a prototypical model of timing behavior in animals (Church, 2002). Part and parcel to this approach has been the assumption that peak intervals and peak rates are representative measures of two independent constructs, timing and motivation respectively. However, recent investigations into motivational influences and the biological underpinnings of timing behavior have resulted in converging models that indicate responding in the peak procedure may actually be a combination of motivational and timing factors (Kirkpatrick, 2014). In pursuit of this, the present study utilized two experimental manipulations to examine the impact of pavlovian conditioned cues on timing and the role of fluoxetine in mediating pavlovian cue effects. The results provided evidence for pavlovian to instrumental transfer effects within the peak procedure and further outlined the role of fluoxetine in impacting response processes.
