Animal 1	75.0±0.4	74.7±1.4	66.2±1.9	53.8±0.8	10.9±0.6
Animal 2	74.4±0.5	76.9±1.1	72.7±0.9	52.2±0.5	11.9±0.8
Animal 3	72.5±0.6	71.6±2.3	79.3±1.9	52.2±0.4	10.2±0.8
All	74.0±0.3	74.9±0.9	72.4±1.1	52.6±0.3	11.1±0.5

Choice (high), Percentage of choosing the higher reward probability goal in each block; Win-stay, percentage of repeating the same goal choice following a rewarded trial; Lose-switch, percentage of switching the goal choice following an unrewarded trial; Choice bias, percentage of the choice for a preferential goal in a given session; Latency to steady state, the number of trials after block transition to reach 90% of the steady-state choice rate (mean choice rate for the last 20 trials in each block). The latency was determined for each block based on a 10-trial moving average curve of the animal's goal choice (Fig. 1C). Data are mean ± SEM.
