The effects of isolation and handling on the reactivity of rats to two tactile stimuli were assessed in two experiments. In the first experiment, reactivity to more intense footshock was increased in rats raised in isolation but was not affected by handling by an experimenter. In the second experiment, increased reactivity to airpuff stimuli presented to the dorsal surface of isolation-reared rats was reduced by handling. The data suggest that the effects of handling on shock-motivated behaviors are not due to altered reactivity to shock and that the effect of housing or handling must be considered in behavioral tests in which reactivity to tactile stimulation might play a role as dependent or independent variables. 相似文献

Even though behavior management is a very high priority of teachers of young children, systems of behavior management receive less attention than do methods of teaching academic content. Even when there are well developed sytems of behavior management, they do not necessarily reflect the same philosophy and methods of teaching that are used to teach content. The authors report on “cognitive-mediational behavior management”, a system designed to be consistent with a cognitive early education program, the Cognitive Curriculum for Young Children. In both behavior management and all their other teaching, teachers use in this program a mediational teaching style. Teachers emphasize thinking processes rather than correct answers, take a problem-solving approach to learning, help children to acquire generalizable strategies of thinking and problem-solving rather than using trial-and-error learning, are optimistic about children’s abilities to learn, and facilitate children’s acquisition of fundamental thinking modes. This system is seen as basically incompatible with a behaviorist, contingent reinforcement system. Behavior sequences are suggested for working with unacceptable behavior so as to produce both behavior change and cognitive change. 相似文献
