Contextual control of conditional discrimination of the own behavior in pigeons

Description

Se llevó a cabo un experimento en el que se entrenó a una paloma en una discriminación contextual de su propia conducta. Cuando estaba iluminada la luz general de la cámara experimental de manera constante, la paloma tenía que picar una tecla roja (o verde) tras haber estado picoteando a la izquierda (o derecha) en el componente de muestra. Cuando la luz general de la cámara se iluminaba de manera parpadeante, las secuencias reforzadas muestra-comparación fueron las contrarias. El sujeto aprendió la tarea en unas 40 sesiones y siguió manteniendo unos altos índices de acierto a pesar de bajar la probabilidad de reforzamiento tras cada ensayo correcto de 1 a 0.2. Los resultados se discuten en relación con el tipo de regla discriminativa y de estructura jerárquica involucradas en esta tarea.

Abstract

An experiment in which a pigeon was trained in contextual discrimination of its own behavior was carried out. When the experimental chamber was illuminated with a constant light, the pigeon had to peck on a red (or green) key in the sample component after having been pecking to the left (or to the right). When the chamber was illuminated with an intermittent light, the reinforced sample-comparison sequences were the opposite. The subject learned the task in about 40 sessions and maintained high correct response ratios even though the reinforcement probability decreased from 1 to 0.2 after each correct trial. The results are discussed in terms of the kind of discriminative rule and the kind of hierarchic structure involved in the task.
