An operant conditioning technique was used to study visual discrimination of simple patterns by infants aged 6-12 weeks. The appropriate direction of head turning to the patterns was developed and maintained by social reinforcement. Results showed that visual discriminative control of the direction of head turning can be achieved. (WY)

Results of this study indicate that learning occurred only under immediate reinforcement and that there was no developmental trend in the ability to withstand the detrimental effects of delayed reinforcement. (WY)

One mildly and two borderline mentally retarded children (10 to 12 years old) were treated for spelling deficits using either overcorrection or overcorrection plus reinforcement. Overcorrection with reinforcement proved to be more effective than overcorrection alone for two of the three children. (Author)

Both the directions and the directions plus reinforcement groups increased subjects' time on the task during the experimental phases. When extrinsic reinforcement and directions were removed, they maintained intrinsically motivated behaviors at levels significantly above levels observed during the baseline phase and significantly higher than the…

It is through the selection of responses that are to serve as the organism's guests that many of the organism's characteristics and outcomes are determined. (MS)

This study assessed the adequacy of Gewirtz's interpretation of vicarious reinforcement and examined the development of responsiveness to vicarious reinforcement in an experiment in which 98 children (21/2-5 years) performed a discrimination problem while being exposed to a model who was either rewarded or punished on each trial.

Explains a simple classroom demonstration of the modern view of classical conditioning. Suggests that the exercise is a useful demonstration of the view that classical conditioning helps prepare an organism for an upcoming event. Argues that the demonstration can show students that classical conditioning is broader and more intriguing than…
