Notes. Food cup entries are percentages of time in the food cup during V2 presentations minus the percentages of time in the food cup prior to V2 presentations. Rear entries are the percentages of observations on which rear behavior was scored during V2 presentations minus the percentages of observations on which rear behavior was scored prior to V2 presentations. Ctl, control groups; ext, extinction groups; n = number of rats, V2, visual stimulus that was reinforced in the reversal training phase and then nonreinforced (ext) or not presented (ctl) in the extinction phase.
