Data from the last five sessions of Phase 1 are shown.

Data from the last session of Phase 2 are shown.

Data from the first session of Phase 3 are shown.

Note: “Sr/Min” refers to the number of reinforcement periods per min earned by each group, while “Pellets/Min” is this value multiplied by the magnitude of reinforcement each group earned.
