Individuals with high intolerance of uncertainty (IU) have been shown to exhibit abnormal threat responding, which may be mediated by hyperactive anterior insula (aINS) response to uncertainty. Research has indicated that individuals with high IU also exhibit abnormal positive valence responding, suggesting that IU may impact responding to uncertainty regardless of the valence of the potential outcome. To date, no study has investigated the neural processes associated with IU and response to uncertain positive stimuli, such as rewards. Therefore, this study was designed to examine the association between individual differences in IU and neural activation during uncertain reward using functional magnetic resonance imaging (fMRI). Thirty-seven adults completed a self-report measure of IU and a reward task during fMRI. Consistent with the threat literature, greater IU was associated with increased aINS activation during uncertain reward. This association was more robust for the prospective IU subscale, a dimension characterized by worry about future events. Together with prior studies, these findings provide evidence that IU is related to abnormal threat and reward responding, and that these deficits may be similarly linked to hyperactive aINS response to uncertainty. 相似文献

This study was aimed at assessing a new computer-based system to promote task performance in three adults with severe developmental disabilities. The new system, which was small and battery powered, could provide auditory and vibratory prompts in addition to pictorial instructions concerning the task steps. To control for the effects of the computer-based system, the subjects were also exposed to a card system. The results showed that the subjects had a significantly higher level of correct performance on the tasks presented with the computer-based system than on the tasks presented with the card system. Two of the subjects, moreover, seemed to prefer the computer-based system to the card system. © 1998 John Wiley & Sons, Ltd. 相似文献

Since the 1970s mental health consumer-run organizations have come to offer not only mutual support, but they have also adopted
agendas for broader social change. Despite an awareness of the need for system level efforts that create supportive environments
for their members, there has been limited research demonstrating how their system level activities can be documented or their
impacts evaluated. The purpose of this paper is to feature a method of evaluating systems change activities and impacts. The
paper is based on a longitudinal study evaluating four mental health consumer-run organizations in Ontario, Canada. The study
tracked system level activities and impacts using both qualitative and quantitative methodologies. The article begins by describing
the development and implementation of these methods. Next it offers a critical analysis of the methods used. It concludes
by reflecting on three lessons learned about capturing system level activities and impacts of mental health consumer-run organizations. 相似文献

The present study sought to explore how women's life experiences influenced their beliefs, and how those beliefs in turn influenced feminist self-identification. Additionally, we sought to determine whether feminist self-identification led to increased collective action on behalf of women. Female participants (N?=?282) from two US college campuses and online listservs completed an online survey assessing feminist self-identification, collective action, and life experiences. Conservative, liberal, and radical beliefs were assessed as were evaluations of feminists. A structural equation model was used to explore these relationships; life experiences were found to influence women's beliefs, which in turn influenced feminist self-identification, which influenced collective action. We found that life experiences may serve as a catalyst for both feminist self-identification and collective action. 相似文献
