Experiment 1. Pavlovian conditioning and outcome-specific transfer. The left panel displays the mean number of magazine entries during the CS presentations and during the pre-CS intervals across days of pavlovian training for the three lesioned groups. The right panels display the mean number of lever presses per minute during the pavlovian-instrumental transfer test (±1 SE of the difference of the means). The number of responses during the baseline period was subtracted from the number of responses during the stimulus presentations to reveal the net excitatory effect of the stimuli. Same refers to the stimulus that predicts the same outcome as that delivered by the lever, whereas Different refers to the stimulus paired with the other outcome.
