Abstract
Septally lesioned and normal rats were trained on a DRL 20 schedule, utilizing an IBM-1800 data acquisition and control system to program the reinforcement contingency and record responses. Normal animals developed a temporal discrimination (as measured by the IRTs/opportunity statistic), while septals did not. Training did not lead to any change in the frequency of reinforcements obtained by either group. These results were discussed in terms of differences in the locus of stimulation (i.e., internal or external) controlling performance.
