Abstract
Pigeons were trained in two experiments that used the concurrent-chains proce-dure. These experiments sought to identify the variables controlling the prefer-ence of pigeons for a constant duration over a variable duration of exposure to an aperiodic, time-based, terminal-link schedule. The results indicated that two variables correlated with the constant-duration terminal link combined to con-trol preference: (a) a shorter initial delay to a rein forcer; and (b) the probabilistic occurrence of multiple rein forcers.
