Delay Component

Following 30 sessions of training on a 60-sec. random-interval schedule of reinforcement, 2 pigeons were exposed to a multiple schedule containing non-contingent and variable delay components that provided equal frequencies of reinforcement. The introduction of the multiple schedule resulted in decreased response rare in both components, with a higher rate maintained under the variable delay. Post-reinforcement pauses were systematically increased during the non-contingent schedule, but no systematic increases in pause duration were noted for the variable delay component.

Extinction Component

Three white Carneaux pigeons were trained to respond on a mult VI 1-min. (milo reinforcement), VI 1-min. (pea reinforcement) schedule when each component was associated with a different key, feeder, and reinforcer. The experiment was divided into four phases. In Phases 1 and 3, baseline rates of responding were established. In experimental Phases 2 and 4, one component of the multiple schedule was changed to extinction. During the experimental phases, response rates decreased in the extinction component and increased in the unchanged component (positive behavioral contrast). The increase in responding in the unchanged component was greater when the more valued reinforcer was extinguished. These findings are very similar to those reported by Beninger and Kendall (1975) and extend the positive contrast effect to another species, pigeons.

Schedule Of Reinforcement

Two white Carneaux pigeons were trained to peck for mixed grain according to a multiple fixed-ratio 50, variable-interval 30-sec schedule of reinforcement. After the rate of responding stabilized, the pigeons were given weekly doses of diphenylhydantoin or an equal volume vehicle Diphenylhydantoin produced a lengthening of the pre-ratio pause and general disintegration of responding during the FR component and a decreased rate of responding in the VI component.
