RESUMEN
Whitaker, Lowe y Wearden reportaron un patrón diferencial de distribución de respuestas en un programa mixto de intervalo fijo de dos componentes, en función de la razón existente entre las duraciones de ambos intervalos. Estos resultados se explicaron aludiendo a la existencia de fuentes diferenciadas de control conductual para ambos componentes. En el presente estudio se pretendía contrastar esta hipótesis incluyendo una señal contextual que señalaba el programa de intervalo activo. Se utilizaron ocho ratas distribuidas en dos grupos con diferente razón y se compararon dos fases, una con discriminativo y otra sin este. Se encontró que la inclusión de la señal alteró la tasa de respuestas en los componentes de menor duración.
ABSTRACT
Whitaker, Lowe and Wearden reported a differential response pattern using a mixed two-component fixed-interval schedule of reinforcement, considering the ratio between the duration of both intervals. These results were explained in regards to the differential behavioral control sources for each component.This study was intended to contrast that hypothesis by including a contextual cue to mark the beginning of each active interval schedule. Eight rats were assigned to two groups with different ratio. In each ratio two conditions were in effect: one with a cue and the other without it. The results showed that the inclusion of the cue changed the response rate in the components with less duration.
