Visual reinforcement: operant acquisition in the presence of a free mirror
Animal Learning and Behavior, 1 (4):
302--306 (November 1973)Abstract
In Exp I 10 male Siamese fighting fish performed operant responses that produced a mirror image to which the S could display. Consistent detectable display was not necessary for maintenance of operant performance. In Exp II, 6 Ss acquired and continued to perform an operant response that produced a mirror, although a "free" mirror was continually present. Display rate to the contingent mirror increased while display rate to the free mirror was decreasing. An interpretation of these and previous data in terms of sensory reinforcement is suggested.
