Discriminación condicional: efectos de las condiciones de adquisición

Abstract

In order to evaluate the effects of acquisition conditions on conditional discrimination, pigeons were trained in a matching to sample task with response-dependent (contingent) and response-independent (non-contingent) reinforcement. Subsequently the reinforcement conditions were reversed: subjects trained with contingent reinforcement were exposed, to non contingent reinforcement, and vice versa. Results show a best acquisition of the conditional discrimination by subjets trained initially with contingent reinforcement, in comparison to the subjets trained with non contingent reinforcement. In all the subjects the performance was un affected by the change in the reinforcement conditions.
