Although people suffering from generalized anxiety disorder (GAD) often report arousal symptoms, psychophysiological studies show no evidence of autonomic hyperarousal. Hypersensitivity toward and catastrophic interpretation of phasic arousal cues may explain this discrepancy. The authors tested (a) whether GAD sufferers perceive nonspecific skin conductance fluctuations (NSCFs), an indicator of phasic autonomic arousal, better than controls do and (b) whether the conviction to be aroused contributes to the maintenance of worrying and metacognitive beliefs about worrying. Thirty-three GAD sufferers and 34 healthy controls participated in 2 experiments. In Experiment 1, participants were asked to detect their own NSCFs during a signal detection task. GAD sufferers accurately detected more of their NSCFs than did controls, who tended to miss NSCFs. In Experiment 2, participants were instructed to relax following worry induction. While relaxing, they received nonveridical feedback indicating either arousal or relaxation. Arousal feedback conserved negative metacognitive beliefs regarding worrying and also maintained negative mood and worry exclusively in GAD participants. These findings suggest that superior perception of phasic arousal cues and their catastrophic misinterpretation increases worrying, negative metacognitive beliefs about worrying, and anxious mood in GAD. 相似文献

Contemporary theories of Pavlovian conditioning propose a distinction between signal learning (SL), in which a conditioned stimulus (CS) becomes a predictor for a biologically significant unconditioned stimulus (US), and evaluative learning (EL), in which the valence of the US is transferred to the CS. This distinction is based largely on the different susceptibilities of EL and SL to extinction. This study compared the extinction of indices of EL (online valence ratings) and SL (US-expectancy ratings and skin conductance responses, SCRs) in a differential fear conditioning design using complex CSs. Only half of the participants gave online valence ratings, allowing us to confirm that online valence measurement did not influence SCRs. In line with the distinction between EL and SL, SCRs extinguished rapidly while valence ratings showed resistance to extinction. US-expectancy ratings, however, were not distinguishable from valence ratings indicating that verbal indicators of EL and SL share a similar time course. 相似文献

Given that parenthood is considered a central adult status with developmental implications, and an increasing number of adults are childless, we assessed whether adult development is structured differently for parents and non-parents. This study’s main goal was to assess and compare the connection between generativity development—a key task of middle adulthood—and psychological well-being for childless adults (N = 289) and parents (N = 2,218), ages 35–74, using the 1995 MIDUS dataset. We also examined differences in these associations for women and men by parental status, because childlessness is often assumed to be more critical for females’ than males’ development. Structural equation modeling indicated a positive association between generativity and psychological well-being. Differences in this association for parents and childless adults were not evident, nor were there significant differences for childless women and mothers, and childless men and fathers. Implications of these findings are discussed. 相似文献

This paper examined the psychometric properties of the German version of the Body Appreciation Scale (BAS), a novel scale for the assessment of positive body image. Based on a community sample of 156 women and 144 men in Austria, results showed good internal reliability and construct validity for the BAS scores, as well as a unidimensional factor structure for both women and men. Specifically, Cronbach's alpha was high for both women ( = .90) and men ( = .85), and the BAS was correlated with the body esteem scale and self-esteem. In addition, women with lower BMIs reported greater body appreciation, but no such association was found for men. Finally, there were small sex differences in BAS scores, with men scoring more positively than women (Cohen's d = 0.26). The German BAS, a useful indicator of positive body image among Austrian adults, should prove valuable for the assessment of body image in German-speaking countries. 相似文献

In this study we investigated whether infant characteristics play a causal role in the occurrence of maternal abuse of offspring in rhesus macaques )Macaca mulatta) and whether abusive mothers differ from controls in their tendency to adopt alien infants in a cross‐fostering procedure. To this end, 13 infants born to mothers with a previous history of infant abuse were cross‐fostered shortly after birth with infants born to nonabusive mothers and subsequently observed for 12 weeks. Abusive mothers were significantly more likely to reject foster infants than control mothers were. When adoption was successful, all of the abusive mothers maltreated their foster infants whereas none of the control mothers exhibited infant abuse. These findings suggest that infant characteristics do not play an important causal role in the occurrence of infant abuse and that abusive mothers may differ from nonabusive ones in maternal motivation or reactivity to stressful procedures. 相似文献

Knowledge of factors affecting eyewitness accuracy was examined in a sample of jurors, judges and law enforcement professionals. Participants completed a survey in which they were asked to agree or disagree with 30 statements about eyewitness issues, and their responses were compared to a sample of eyewitness experts who completed the same survey. Participant responses differed significantly from responses of eyewitness experts. Jurors disagreed with the experts on 87% of the issues, while judges and law enforcement disagreed with the experts on 60% of the issues. The findings show a large deficiency in knowledge of eyewitness memory amongst jurors, judges and law enforcement personnel, indicating that the legal system may benefit from expert assistance in the evaluation of eyewitness evidence.
