Talking circles, as a unique instructional approach, can be used to stimulate multicultural awareness while fostering respect for individual differences and facilitating group cohesion. A brief history of the talking circle is followed by detailed instructions, talking circle process questions, ideas for classroom discussion after the activity, and teaching strategies. Círculos de conversación, como un método singular de pedagogía, se puede utilizar para estimular consciencia multicultural, mientras a la vez promueve el respeto para las diferencias individuales, y facilita cohesión grupal. Le sigue a una breve historia del círculo de conversación unas instrucciones detalladas, preguntas para procesar el círculo, ideas para discusión en clase despues de la actividad, y estrategias pedagógicas. 相似文献

Epigenetic testing is one of the most significant new technologies to provide insight into the behavioral and environmental factors that influence the development and reconfiguration of the human genetic code. This technology allows us to identify structural changes in the genome that occur due to exposure to a wide variety of substances including alcohol, tobacco, and cannabis. The information gained can be used to promote health but it also raises a variety of ethical, legal, and social issues. As society progresses in understanding the epigenetic mechanisms of substance use and addiction, there is an opportunity to use these use this knowledge to enable medical, behavioral, and environmental interventions to alleviate the burden of addiction. This article describes the ethical issues associated with use of epigenetic testing for alcohol, tobacco, and cannabis and the implications of this technology. A further review of the scientific basis for the relevance of epigenetics is found in the accompanying article by Philibert and Erwin in this issue. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

Complex motor learning, but not mere motor activity, has been previously shown to induce structural modifications within the cerebellar cortex. The present experiment examined whether similar changes occur within one of the primary output targets of the region of the cerebellar cortex in which these structural changes were described, the lateral cerebellar nucleus (LCN; dentate nucleus). Adult female rats were randomly allocated to one of three training conditions. Acrobatic condition (AC) rats were trained to complete a complex motor learning task consisting of a series of elevated obstacles while motor control (MC) condition animals were forced to traverse a flat obstacle-free runway equal in length to the AC task. Inactive condition (IC) animals received no motor training. Unbiased stereological techniques and electron microscopy were used to obtain estimates of synapse number and postsynaptic density (PSD) length within the LCN. Results showed that neither synapse number nor PSD length was significantly altered as a function of training condition. These results indicate that complex motor skill learning is associated with structural plasticity within the cerebellar cortex and with structural stability within the lateral cerebellar nucleus. 相似文献

Forty college students were taught facilitated communication via a commercially available training videotape. They were then asked to facilitate the communication of a confederate, who was described as developmentally disabled and unable to speak. All 40 participants produced responses that they attributed at least partially to the confederate, and most attributed all of the communication entirely to her. Eighty-nine percent produced responses corresponding to information they had received, most of which was unknown to the confederate. Responding was significantly correlated with simple ideomotor responses with a pendulum and was not affected by information about the controversy surrounding facilitated communication. These data support the hypothesis that facilitated communication is an instance of automatic writing, akin to that observed in hypothesis and with Ouija boards, and that the ability to produce automatic writing is more common than previously thought. 相似文献

The "pre-delinquent" behaviors of six boys at Achievement Place, a community based family style behavior modification center for delinquents, were modified using token (points) reinforcement procedures. In Exp. I, point losses contingent on each minute late were effective in producing promptness at the evening meal. During the reversal phase, threats (which were not backed up with point losses) to reinstate the point consequences initially improved promptness but the last two of five threats were ineffective. In Exp. II, point consequences effectively maintained the boys' room-cleaning behavior and, during a fading condition where the percentage of days when the contingency occurred was decreased, the point consequences remained effective for over six months, even when they were delivered on only 8% of the days. Experiment III showed that the boys saved considerable amounts of money when point consequences were available for deposits but saved little money when no points were available. Also, when points were given only for deposits that occurred on specific days the boys deposited their money almost exclusively on those days. In Exp. IV, point consequences contingent on the number of correct answers on a news quiz produced the greatest increase in the percentage of boys who watched the news and, to a lesser extent, increased the percentage of correct answers for the boys who watched the news. The results indicate that "pre-delinquent" behaviors are amenable to modification procedures and that a token reinforcement system provides a practical means of modifying these behaviors. 相似文献

Six 4-year-old Ss were presented with a textual program consisting of 26 words arranged so the word stimuli were gradually combined into sentences and then short “stories.” Three Ss were given the No-Reinforcement condition first, and only social reinforcers were presented. They were switched to the Reinforcement condition as soon as they requested discontinuance of the activity. The other three Ss were given Reinforcement—No Reinforcement—Reinforcement treatments. The No-Reinforcement treatment in this case lasted until S requested discontinuance of the activity. The reinforcers were mixed edibles and trinkets, as well as tokens backed up by small plastic toys on a 1:24 ratio. The unit of response was the number of new texts acquired as a result of each of the 45-min experimental sessions. It was demonstrated that the program, procedure, and reinforcement conditions produced curves which are analogous to those produced in common operant-conditioning procedures. The results indicate that other operant principles may be studied in this significant area of human behavior, with important practical consequences. 相似文献
