Saccadic reaction time distributions follow the matching law in a concurrent variable interval reinforcement schedule

A dynamic foraging task On each trial, the subject makes a saccade toward a target. Rewards are assigned to fast and slow latencies at rates that are independent and stochastic. Once assigned, a reward remains available until collected. Saccadic reaction time distributions are strongly affected by reinforcement (Madelain et al, 2007); we now ask whether saccade latencies could match reinforcement proportions in a concurrent schedule.
