Individuals with anxiety disorders show deficits in the discrimination between a cue that predicts an aversive outcome and a safe stimulus that predicts the absence of that outcome. This impairment has been linked to increased spontaneous recovery of fear following extinction, however it is unknown if there is a link between discrimination and return of fear in a novel context (i.e. context renewal). It is also unknown if impaired discrimination mediates the relationship between trait anxiety and either spontaneous recovery or context renewal. The present study used a differential fear conditioning paradigm to examine the relationships between trait anxiety, discrimination learning, spontaneous recovery and context renewal in healthy volunteers. Fear learning was assessed using continuous ratings of US expectancy and subjective ratings of fear. Discrimination mediated the relationships between trait anxiety and both spontaneous recovery and context renewal such that elevated trait anxiety was associated with poorer discrimination, which in turn was associated with increased fear at test phases. Results are discussed in terms of the genesis and maintenance of anxiety disorders.  相似文献

Previous studies have shown that punishing people through a large penalty for volunteering incorrect information typically leads them to withhold more information (metacognitive response bias), but it does not appear to influence their ability to distinguish between their own correct and incorrect answers (metacognitive accuracy discrimination). The goal of the current study was to demonstrate that punishing people for volunteering incorrect information—versus rewarding volunteering correct information—produces more effective metacognitive accuracy discrimination. All participants completed three different general-knowledge tests: a reward test (high points for correct volunteered answers), a baseline test (equal points/penalties for volunteered correct/incorrect answers) and a punishment test (high penalty for incorrect volunteered answers). Participants were significantly better at distinguishing between their own correct and incorrect answers on the punishment than reward test, which has implications for situations requiring effective accuracy monitoring.  相似文献

Why does the public have such polarizing views on the poor? This paper attempts to understand this issue by examining and exploring what predicts attitudes towards the poor. The exploration of this issue begins with a reference to the Moral Foundations Theory (MFT) and how this particular framework has been used to explain polarizing issues such as abortion, gay marriage and stem cell research, among others. This paper argues that the MFT can provide a similar insight on attitudes towards the poor. With the MFT as a backdrop, the current study tested out the hypothesis using hierarchical multiple regression and explored the results further by using dominance analysis. Results showed that the Moral Foundations were good predictors of attitudes towards the poor. While Harm emerged as the only significant predictor, dominance analysis revealed the importance of each foundation as predictors. Harm is the strongest predictor followed by Fairness, Authority, Ingroup, and Purity. All five foundations appear to be better predictors as compared to one’s political affiliation.  相似文献

A bidirectional relationship between sleep and anxiety is well-established whereby difficulties in one domain predict problems in the other. Interventions for childhood sleep-related problems also share considerable overlap with interventions for anxiety. Although anxious youth report high rates of sleep-related problems, it is relatively unknown whether anxiety-focused interventions for children produce improvements in sleep-related problems. The current study included N = 25 youth ages 7–16 (13 female; mean age 9.92 years ± 2.6) who participated in an early intervention program for anxiety as part of the Arizona Anxiety Resilience Building Project. Child and parent measures of sleep and anxiety symptoms were examined before and after the 12-week cognitive-behavioral intervention program. Statistically significant decreases in total sleep-related problems, bedtime resistance, sleep anxiety, and pre-sleep arousal were observed at post-intervention, though clinically meaningful change was apparent in only a small portion of the sample. Results suggest that purely anxiety-focused interventions may be useful for reducing certain types of sleep-related problems in anxious children, specifically those that occur during the bedtime/pre-sleep period. However, a lack of clinically meaningful change, in addition to post-intervention sleep-related problem scores above the clinical cut-off in a large proportion of the sample, suggest that the sleep-related problems of anxious youth may require direct attention as part of treatment.  相似文献

This study sought to validate the Intrinsic Work Rewards Scale (IWRS) using a transnational sample. Respondents were 486 non-profit employees from Australia, South Africa and the United States of America (females = 72.0%; managerial/ supervisory job level employees = 57.4%). Data analysis included reliability testing, exploratory and confirmatory factor analysis, and concurrent validity testing with established measures to which the IWRS is theoretically linked. The scores from the IWRS obtained an overall acceptable reliability coefficient of 0.86. Factor analysis confirmed its five factor structure, and correlations indicated that intrinsic rewards are positively related to work engagement, and negatively related to intention to quit. The IWRS appears to yield reliable scores for human resource managers advising in the non-profit employment sector.  相似文献

Blatt's (2004 Blatt, S. J. (2004). Experiences of depression: Theoretical, clinical, and research perspectives. Washington, DC: American Psychological Association.[Crossref] [Google Scholar], 2008 Blatt, S. J. (2008). Polarities of experience: Relatedness and self-definition in personality development, psychopathology, and the therapeutic process. Washington, DC: American Psychological Association.[Crossref] [Google Scholar]) conceptualization of self-criticism is consistent with a state–trait model that postulates meaningful variation in self-criticism both between persons (traits) and within person (states). We tested the state–trait model in a 7-day diary study with 99 college student participants. Each evening they completed a 6-item measure of self-criticism, as well as measures of perceived social support, positive and negative affect, compassionate and self-image goals during interactions with others, and interpersonal behavior, including overt self-criticism and given social support. As predicted, self-criticism displayed both trait-like variance between persons and daily fluctuations around individuals' mean scores for the week; slightly more than half of the total variance was between persons (ICC = .56). Numerous associations at both the between-persons and within-person levels were found between self-criticism and the other variables, indicating that individuals' mean levels of self-criticism over the week, and level of self-criticism on a given day relative to their personal mean, were related to their cognitions, affect, interpersonal goals, and behavior. The results supported the construct validity of the daily self-criticism measure. Moreover, the findings were consistent with the state–trait model and with Blatt's theoretical analysis of self-critical personality.  相似文献

With a few exceptions, the problem of linking item response model parameters from different item calibrations has been conceptualized as an instance of the problem of test equating scores on different test forms. This paper argues, however, that the use of item response models does not require any test score equating. Instead, it involves the necessity of parameter linking due to a fundamental problem inherent in the formal nature of these models—their general lack of identifiability. More specifically, item response model parameters need to be linked to adjust for the different effects of the identifiability restrictions used in separate item calibrations. Our main theorems characterize the formal nature of these linking functions for monotone, continuous response models, derive their specific shapes for different parameterizations of the 3PL model, and show how to identify them from the parameter values of the common items or persons in different linking designs.  相似文献
