Lateralized audiogenic seizure: motor asymmetries exhibited and the effects of interrupted stimulation 总被引:2,自引:0,他引:2
Sensitized SJL/J mice were monaurally tested for susceptibility to sound-induced seizure. The acoustic stimulation was interrupted for 15 s at various points during the biphasic pattern of running which these mice characteristically exhibit before seizing. Asymmetries of run directions and side of fall were noted. In addition, a dramatic reduction in seizure incidence was found when the interruption either extended into the period when the later burst of running would have occurred or began during this running burst. Finally, the results indicate that the latencies to the later running burst and the subsequent seizure are determined at or about the time of the onset of the first burst of running. 相似文献

A helpful component for comprehensive residential services for developmentally disabled persons is volunteer assistance. This investigation involved the evaluation of a program developed to increase the amount of volunteer assistance provided to a public residential facility. The program consisted of three types of related procedures: systematic volunteer recruitment steps, specific volunteer activities at the facility, and consequence/recognition for the volunteer assistance. The program was successively implemented to involve students as volunteers from two local universities, and resulted in an increase in new students volunteering from both universities. Additionally, the frequency with which the students volunteered at the residential facility increased substantially from both universities relative to control periods during which the volunteer program was not in effect. Results are discussed in terms of the benefits of volunteers and continued research to increase involvement of other prospective groups of volunteers. 相似文献

Self-meaningfulness, a concept arising from personal construct theory research, has been defined in terms of the importance of the self in the personal construct system Forty-two undergraduate volunteers completed Repertory Grid ratings of the self and 15 individuals (five liked, five disliked, and five toward whom the subject was neutral) It was found that high self-meaningfulness individuals' ratings of attraction were more strongly associated with the perception of similarity than were the ratings of low self-meaningfulness subjects High self-meaningfulness subjects saw liked individuals as significantly more similar to the self than did low self-meaningfulness subjects In addition, liked, neutral, and disliked figures were seen as significantly different from one another on the similarity to self-measure for high self-meaningfulness subjects Only disliked figures were judged as more distant from the self for low self-meaningfulness subjects These findings were discussed in terms of the importance of investigating individual differences in similarity-attraction 相似文献

A developmental model of antisocial behaviour is presented in this paper. Arguments and evidence are presented for the position that although many factors such as parent criminality, social and economic disadvantage, child temperament, and marital discord systematically affect the development of antisocial child behaviour, their influence is mediated by the extent to which they disrupt day-to-day parenting practices. Particularly, it is argued that irritable, ineffective discipline and poor parental monitoring are the most proximal determinants of the early development and maintenance of antisocial behaviour. The implications of this model for prevention and intervention in child conduct problems are discussed, using examples of promising clinical work that focuses on direct parent training. 相似文献

In this study we attempted to operationalize, measure, and increase happiness among people with profound disabilities. Happiness indices were defined and observed among 5 individuals. Validation measures indicated that (a) increases in happiness indices were observed when individuals were presented with most preferred stimuli relative to least preferred stimuli, (b) increases in unhappiness indices were observed when they were presented with least preferred relative to most preferred stimuli, and (c) practitioner ratings of participant happiness coincided with observed indices. Subsequently, classroom staff increased happiness indices through presentation and contingent withdrawal of activities. Results suggested that a behavioral approach can enhance happiness as one aspect of quality of life among people with profound disabilities. Research directions are offered that focus on using a behavioral approach to investigate other private events that are important among people with disabilities. 相似文献
