Abstract
Examination of pigeons’ key-pecking performance, reinforced on concurrent variable-interval 1-min variable-interval 3-min schedules, as a function of the changeover delay revealed the following relationships. As the changeover delay was increased from 0 through 20 sec (1) relative response frequency on the key color associated with the 1-min schedule increased, (2) relative time spent in the 1-min schedule increased, (3) obtained relative frequency of reinforcement in the 1-min schedule increased, and (4) changeover rate decreased.
