An examination of vicarious reinforcement processes in children

The primary purpose of the present investigation was to examine vicarious reinforcement processes in children. More specifically, the effects on one child of observing another same-sex child receive direct reinforcement were explored across three different age levels. Subjects were 216 children, randomly assigned to experimental or control conditions. For the control condition, neither child in the same-sex, same-age dyad received reinforcement for performance on the experimental task. For the experimental condition, one child in each dyad received direct social reinforcement for performance, while the other child received no social reinforcement for similar performance. Although children who observed other children receive direct social reinforcement initially increased performance (as predicted by vicarious reinforcement hypotheses), their performance soon decreased and was characterized by verbal and nonverbal responses which appeared to interfere with task performance (e.g., “Hey, I can do them too”, “Look at mine”, “There's no use in trying”). It appeared as if these observing children were being punished for their performance. Such effects were more pronounced for older than younger children; however, they were observed equally in boys and girls. Results were discussed in terms of vicarious reinforcement and “implicit punishment” hypotheses. Implications for applied settings were also addressed.     

The relaxation word of the day: A simple technique to measure adherence to relaxation

A new procedure of assessing adherence to home practice of relaxation is presented. The technique involved the subject identifying one of four possible relaxation words of the day at the end of a taped relaxation session. The method was employed to assess the relationship between adherence to relaxation and decline of blood pressure during a 10-session/8-week relaxation program involving 17 hypertensive subjects. No statistically significant relationship was found on either a short-term or a long-term basis. An advantage of the assessment technique is that it appears easily integrated into the overall therapeutic objective for relaxation therapy; a disadvantage is that the subject needs to comply not only with the relaxation schedule but also with the monitoring procedure.This research study was funded by NIH Grant HL27159.     

Effects of arousal on human visual dominance

Human attention research has found that vision controls attention when competing against other sensory modalities, for example, audition, proprioception, taction. Similarly, animal learning experiments have demonstrated visual attentional control when animals are positively motivated but auditory control when aversively motivated. The experiments with animals suggest a way of attenuating visual dominance in humans. Three experiments using human subjects explored the degree of visual versus auditory control exhibited in the presence of different arousal states. In Experiments 1 and 2, an electric shock and a threat of electric shock, respectively, to the subject’s finger resulted in auditory attentional control In Experiment 3, a tactile stimulus resulted in attenuated visual control. The results of these experiments are discussed in relation to the evolutionary advantage conferred by such attentional strategies.     

Food-reinforced inhibition of conditioned salivation in dogs.

Twelve dogs salivated to a tone that was followed by food, but not to a noise for which there was an added response dependency. The noise was followed by food if and only if they did not salivate. The addition of this response dependency vitiated the classically conditioned response to the noise. A yoked-control group of 6 dogs receiving the same sequences of stimuli and food salivated to both the tone and noise stimuli.     

Family therapy in treatment of the deaf: a case report.

Deaf patients with psychological problems have developmental handicaps and clinical characteristics that reduce the effectiveness of traditional modes of psychotherapy. Attempts have been made to utilize individual and group therapy, but family therapy has been largely overlooked as a method of alleviating problems of the deaf. Clinical and research writings provide us with rich insights into the family dynamics of the deaf. These data suggest to the authors that the problems of deaf individuals are largely related to family problems, and therefore merit a family orientation as the focus for treatment. This paper describes an attempt to apply family therapy with a range of deaf patients over a period of two years. From a review of their work, the authors conclude that family therapy can be effective, particularly in the treatment of deaf adolescents and children.
