The present experiments investigated the effects of several classical conditioning manipulations on the performance of young children in an instrumental discrimination learning situation. Two predictions from general conditioning-extinction theory were tested: (1) acquisition of an instrumental response to a stimulus for a positive reinforcer in a…

The results of a group of studies, the objective of which was to clarify the conditions that account for the effectiveness of verbal approbation, are reported. Among the most significant findings were: (1) that the reinforcement properties of verbal approval are susceptible to distortion, misinterpretation or enhancement and must be applied in a…

Three studies, using handicapped children, investigated: effects of three different reinforcement contingencies (positive reinforcement, removal of positive reinforcement, and combination of positive reinforcement and removal of positive reinforcement) on a steady-state discrimination task; effect of a conditioned emotional response procedure on a…

Response and reinforcement features of operant discrimination paradigms used in audiometric assessment were investigated with normal 17-month-old children. Findings indicated more responses prior to onset of habituation when response tasks involved complex central processing skills and a twofold increase in number of subject responses when…

An institutionalized, retarded, adult male's response to verbal commands was increased through the use of positive control of a discriminative stimulus. Operant conditioning was noted as a possible means of enabling retarded individuals to acquire behaviors fundamental to a self-help repetoire. (Editor)

Several 3- to 5-year-old children participated in this study designed to discover the necessary procedures to establish nonresponding in preschool children during delay of reinforcement. The children were divided into two groups: (1) the programed group (PG), to which a 60-second delay period was introduced gradually and (2) the baseline group…

Two 4-year-old children were shown the use of an apparatus whereby they could obtain toys and candy by making certain responses. The apparatus was a matching-to-sample device on which were arranged five response buttons in a circle and one in the middle. Each response button had a display window for the stimulus. Four of the five windows on the…

This study investigated the effects of availability of a familiar human attachment object (the mother) and familiar inanimate attachment object (the child's blanket) on a child's emotionality and learning of a discrimination task. A total of 64, 2- and 3-year-old children were assigned to groups (nonattached, mother-attached, or blanket-attached),…

Using a conditioned suppression task, we investigated extinction and renewal of Pavlovian modulation in human sequential Feature Positive (FP) discrimination learning. In Experiment 1, in context a participants were first trained on two FP discriminations, X[right arrow]A+/A- and Y[right arrow]B+/B-. Extinction treatment was administered in the…
