Le renforcement non contingent est en concurrence avec le rendement de la réponse

Aperçu: G.M.
Le renforcement non contingent (Cliquer ICI pour en savoir plus sur le calendrier de renforcement) est une procédure couramment utilisée pour diminuer les niveaux de comportement problématique. Les objectifs de cette intervention sont de diminuer la motivation, la réponse et la relation fonctionnelle entre les comportements et les conséquences, mais cela pourrait aussi concurrencer la performance de réponses alternatives souhaitables.
Dans l'étude en cours, les chercheurs ont évalué les effets du renforcement non -contingent organisé de 0% à 100% des sessions sur la performance de réponses alternatives lors de deux expériences avec des humains et des animaux. 
Les résultats montrent dans l'ensemble, que de plus grandes quantités de renforcement non-contingents viennent en concurrence avec l'acquisition et la maintenance de réponses alternatives.

Abstract

Noncontingent reinforcement is a commonly used procedure to decrease levels of problem behavior. Goals of this intervention are to decrease motivation, responding, and the functional relation between behavior and consequences, but it could also possibly compete with performance of alternative desirable responses. In the current study, we assessed the effects of noncontingent reinforcement arranged from 0% to 100% of sessions on performance of alternative responding across two experiments. Experiment 1 assessed manding (i.e., requests) maintained by attention and tangibles with a child with developmental disabilities and Experiment 2 assessed keypecking maintained by food with six pigeons. We extended previous research by (a) showing that noncontingent reinforcement competes with both the acquisition and maintenance (performance) of an alternative response, (b) extending the generality of the findings across nonhuman and human participants, and (c) eliminating influence of sequence effects through random manipulations of noncontingent value in pigeons. Overall, greater amounts of noncontingent reinforcement competed with both acquisition and maintenance of alternative responding.
