The interconnection of repertoires is a behavioral process related to problem solving and the origins of new behavior. The present study observed the effects of concomitant and successive training of (a) dig, and; (b) climb, upon the interconnection of repertoires in rats (Rattus norvegicus). Pairs of rats received different trainings before testing. In the first condition, a pair of rats received two sessions per day, one of dig and the other of climbing (concomitant condition, n=2). A second pair of subjects first learned to dig, and then to climb (successive condition, n=2). In a third condition (n=2), rats learned the two repertoires in a successive manner, and had retraining sessions of the first trained repertoire before testing. To test the interconnection, rats were exposed to a new task that required a sequence of behaviors never trained: the animals had to dig and find a tunnel, which leaded to a flight of stairs containing food at its end. All subjects solved the final task, but with different topographies of problem solving. Rats of the concomitant condition solved the problem in less time than rats in other conditions. A discussion is offered regarding the general effects of different training variables upon the interconnection of repertoires and the criteria used to evaluate different problem solving topographies.
