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.
