Abstract

The interconnection of repertoires is a behavioral process related to problem solving and creativity. Experiments on this topic have mostly used a single reinforcer type during training. Reinforcers have an integrative effect on the emergence of new behavior; however, this assumption was never directly tested in procedures that result in the emergence of the interconnection of repertoires. To test this, six pigeons learned to: (1) push a box towards a light and (2) climb a box and peck a target. After training, pigeons were exposed to the box displacement test, a problem situation that required both behaviors to be solved. Two birds were trained with food as reinforcer for both repertoires (control condition [CC]), and four birds (experimental condition [EC]) had food as reinforcer for repertoire (1), and water for (2). CC birds solved the test in its first presentation, but EC birds did not. Birds that failed the test twice received a retraining of both repertoires, using only food as reinforcer. Half of the pigeons who received this retraining solved the task in a third trial. All pigeons that solved the task (n = 4) were given variations of the task consisting of introducing new stimuli, which, when physically similar to the functional stimuli, hindered the solution. These data indicate that the reinforcer has a similar integrative and discriminative function during the interconnection of repertoires as observed in other behavioral processes related to emergent behavior. The implications of these findings for research on creativity are discussed.
