Two experiments were conducted to investigate the effects of positive and negative reinforcements upon black college students. In the first experiment subjects received either positive or negative reinforcement from a black or a white Evaluator. Behavioral change (compliance) was greater in response to negative reinforcement from a black Evaluator than in response to negative reinforcement from a white Evaluator, while there were no divergent effects of Evaluator's Race upon compliance with positive reinforcement. The same pattern obtained in subjects' self-evaluations. The second experiment offered a test of the hypothesis that the objectivity of black Evaluators was perceived as greater than that of white Evaluators, and that a manipulation aimed at equating the Evaluators on objectivity would attenuate the effects of Evaluator's Race upon compliance and self-evaluation in response to negative reinforcement. These hypotheses were generally supported by the results.  相似文献

A handedness questionnaire was administered to 446 stutterers and a control group. No significant male/female or stutterer/control effects were found, although both males and stutterers tended to be less right handed. The slight sex effect in handedness is consistent with previously reported studies and with cerebral structural and functional asymmetries.  相似文献

Token-mediated access to play and snacks was made contingent on completion of academic tasks in the Baseline Experiment. This contingency produced stable completion rates that were subsequently doubled, and then tripled, for four deviant children in a special preschool. A reversal design demonstrated that the contingency was functional in maintaining the children's rates of task completion. The Guidance Experiment examined the role of a social event, teacher guidance, in the acquisition of task-completion skills, in a multiple-baseline-across-tasks design (with reversals). The analysis demonstrated that teacher guidance was an important supplement to the token-mediated contingency in establishing significant increases in task completions for a second group of three deviant children in the special class. The importance of teacher guidance was related to the difficulty level of the children's tasks.  相似文献

Counterconditioning is a process in which aversive stimuli that ordinarily evoke emotional or avoidance responses are paired with positive stimuli which evoke incompatible activities. Several sets of operations have been employed to induce these incompatible activities (e.g. food, Jones, 1924; relaxation. Grossberg, 1964; positive imagery, Lazarus and Abramowitz, 1962; pharmacological agents, Friedman, 1966; laughter, Ventis, 1973).Although the Counterconditioning process has been successfully applied to a wide variety of emotional disorders, special problems arise when the procedure is applied to the mentally retarded. First, because of the limitations in cognitive abilities, it is generally impossible to train the subject in either relaxation or positive imagery processes. Consequently, it is necessary to place the child in direct contact with the anxiety-inducing situation. Secondly, it is often difficult to find an anxiety-free situation which is incompatible with the anxiety-arousing situation and which can be practically implemented, particularly when the phobia involved is complex.The purpose of this paper is to describe a case whereby a phobic response of physical examination by male doctors in a 7–yr-old mentally retarded boy was extinguished by pairing the examination with an anxiety-free situation, i.e. an extremely comfortable relationship between the patient and a nurse on the ward. Previous research had indicated that parents and people who have positive relationships with a person might possibly serve as effective anxiety reducers in fear-provoking situations (Jersild and Holmes, 1935).  相似文献

Interest in resilience is surging in research, policy and practice as threats from disasters rise and humanity confronts a global pandemic. This commentary highlights the importance of defining resilience for portability across system levels and disciplines in order to integrate knowledge and prepare adequately for the challenges posed to children and youth by multisystem disasters. A scalable definition of resilience is recommended: The capacity of a dynamic system to adapt successfully to challenges that threaten the function, survival or development of the system. Major determinants of adaptation among young people in the context of disaster are highlighted, including variations in adversity exposure dose, developmental timing, individual differences and the socio-ecological systems of children's lives that can be mobilised in response. Adaptation of children in disasters depends on the resilience of interconnected systems, including families, schools, communities and policy sectors. Implications of a multisystem perspective for disaster risk reduction and preparedness are discussed with a focus on nurturing the resilience of children and their societies for challenges in the near term and long into the future.  相似文献

We investigated ADHD symptoms and CU traits as predictors of violent media use in adolescence, controlling for delinquency and ODD symptoms. The effects on of disinhibition and arousal to negative stimuli, core characteristics of ADHD symptoms and CU traits, and of gender were investigated. At age 15, 88 adolescents, 50 % boys reported on CU traits, ADHD symptoms and delinquency. Parents rated the adolescents’ CU traits, ADHD‐ and ODD symptoms. At age 16, adolescents reported on their media habits and performed tests of disinhibition and arousal to negative stimuli. Boys had higher levels of CU traits and violent media use and girls had higher levels of arousal to negative pictures. CU traits and inattention symptoms predicted violent media use, the latter association applying only to boys, with CU traits being the strongest predictor. Low arousal to threat pictures explained variance in violent media use, above CU traits. Attraction to violent media seems affected by problem behaviors, with CU traits coming forth as especially important.  相似文献
