Interval Functions

Human Ss were given differential eyelid conditioning at CS-UCS intervals of 400, 600, and 800 msec. to visual CSs separated by 1.25 and 2.50 in. The CS outlines were not visible to S during the intertrial interval as they customarily are in spatial discrimination tasks. CS+ response levels increased with interval throughout the range employed with CS− levels increasing only through 600 msec. No differentiation was observed at 400 and 600 msec. intervals at either level of separation. These results indicate that CS-UCS interval functions in differential conditioning cannot be generally defined and must be related to the conditions employed in a given experiment.

Automated Procedures

4 stumptail monkeys and 4 albino rats were trained in a discrete-trials latency-correlated reinforcement (DRL) situation. Phenomena investigated were: (a) acquisition of temporal discriminations, (b) effects of within- S intertrial interval variations, (c) disinhibition of responses by novel extraneous stimuli, (d) effects of reinforcement magnitude, and (e) differential conditioning based upon reinforcement of short vs long latencies. Detailed quantitative descriptions of these phenomena were obtained by automated procedures permitting direct species comparisons.
