The available empirical literature suggests that anger may be characteristic of posttraumatic stress disorder (PTSD). Meta-analytic strategies were used to evaluate the extent to which the experience of anger is specific to PTSD rather than anxiety disorders in general. Thirty-four anxiety disorder patient samples (n = 2,169) from 28 separate studies were included in the analysis. Results yielded a large effect size indicating greater anger difficulties among anxiety disorder patients versus controls. Compared to control samples, a diagnosis of PTSD was associated with significantly greater difficulties with anger than was any other anxiety disorder diagnosis. Other anxiety disorder diagnoses did not differ significantly from each other. However, the specific association between PTSD and anger did vary depending on the anger domain assessed. Difficulties with anger control, anger in, and anger out significantly differentiated PTSD from non-PTSD anxiety disorder samples, whereas difficulties with anger expression, state anger, and trait anger did not. These findings are discussed in the context of future research on the role of anger in PTSD. 相似文献

Emotion and psychopathology researchers have described the fear response as consisting of four main components--subjective affect, physiology, cognition, and behavior. The current study provides evidence for an additional component in the domain of height fear (perception) and shows that it is distinct from measures of cognitive processing. Individuals High (N = 35) and Low (N = 36) in acrophobic symptoms looked over a two-story balcony ledge and estimated its vertical extent using a direct height estimation task (visual matching), and an indirect task (size estimation); the latter task seems to exhibit little influence from cognitive factors. In addition, implicit and explicit measures of cognitive processing were obtained. Results indicated that, as expected, the High Fear group showed greater relative, implicit height fear associations and explicit threat cognitions. Of primary interest, the High (compared to Low) Fear group estimated the vertical extent to be higher, and judged target sizes to be greater, even when controlling for the cognitive bias measures. These results suggest that emotional factors such as fear are related to perception. 相似文献

Binary multinomial processing tree (MPT) models parameterize the multinomial distribution over a set of J categories, such that each of its parameters, θ1,θ2,…,θS, is functionally independent and free to vary in the interval [0,1]. This paper analyzes binary MPT models subject to parametric order-constraints of the form 0?θs?θt?1. Such constraints arise naturally in multi-trial learning and memory paradigms, where some parameters representing cognitive processes would naturally be expected to be non-decreasing over learning trials or non-increasing over forgetting trials. The paper considers the case of one or more, non-overlapping linear orders of parametric constraints. Several ways to reparameterize the model to reflect the constraints are presented, and for each it is shown how to construct a new binary MPT that has the same number of parameters and is statistically equivalent to the original model with the order constraints. The results both extend the mathematical analysis of the MPT class as well as offering an approach to order restricted inference at the level of the entire class. An empirical example of this approach is provided. 相似文献

The authors investigated whether different campus environment factors were related to eating disorder symptomatology at two distinctly different colleges. The first campus was conservative, placing an emphasis on appearance and dress, whereas the second campus was liberal, placing an emphasis on political activism and intellectual talent. As hypothesized, the two schools did not differ in regard to overall levels of eating disorders, yet different factors were associated with eating disorder symptomatology at each school. Implications for eating disorder interventions on college campuses are discussed. 相似文献

Subjects were required to describe line drawings of two-dimensional shapes at two levels of verbal codability, with and without using hand gestures. Elimination of gesture affected speech performance by changing the semantic content of utterances and the proportion of speaking time spent pausing; numbers of words, numbers of pauses, mean pause length and semantic content were found to be related to the verbal codability of the stimulus material; and the number of hesitations was related to both gesture and level of codability. 相似文献

Mathematics textbooks sometimes present worked examples as being generated by particular fictitious students (i.e., person-presentation). However, there are indicators that person-presentation of worked examples may harm generalization of the presented strategies to new problems. In the context of comparing and discussing worked examples during extended classroom instruction, the current study compared the impact of person-presentation to strategy labels on students' posttest accuracy and ratings of strategy generalizability. Five algebra teachers and their 168 students used worked examples either presented using fictitious students or with a strategy label during a multiweek unit on equation solving, with teachers randomly assigned to condition. All students compared and discussed the worked examples. In this context, we found no effect of condition on student accuracy at posttest, nor on their ratings of the generalizability of the presented strategies. We discuss why previously found negative effects of person-presentation may not have extended to this context. 相似文献

The relationship between aging and negative affect is dynamic and complex. Although prior studies have often cited lower prevalence rates of anxiety and mood disorders among older individuals, these studies may miss the dynamic relationship between symptoms and aging. To evaluate a nonlinear model of the relationship between aging and negative affect, the author examined measures of neuroticism, anxiety, and depression symptoms in a cross-sectional, community sample (N = 335), ages 18 to 93. Results indicated a curvilinear relationship, with mean symptom levels increasing during early adulthood (until the mid-30s) and then showing a small decline until older adulthood (the mid-70s), when symptoms again increase with age. 相似文献

Two experiments were performed to test a psychophysical account of parallels between biases in risky choice and intertemporal choice. Experiment 1 demonstrated the common difference effect in intertemporal choice and the common ratio effect in risky choice. As was predicted, these two biases were uncorrelated with each other, although each was correlated across monetary/health domains. This result is consistent with the supposition that these two biases result from psychophysical properties of two different dimensions (time and probability, respectively). Experiment 2 examined the magnitude effect in intertemporal choice and the peanuts effect in risky choice. These two biases were correlated with each other but were uncorrelated across monetary/health domains. This result is consistent with the supposition that these two biases result from psychophysical properties of the same dimension (utility of money or health). 相似文献

In recognition memory experiments, Nosofsky and Zaki (2003) found that adding discrete distinctive features to continuous-dimension color stimuli helped participants to identify old items as old (the old-item distinctiveness effect), as well as to identify new items as new. The present study tests the extent to which these results generalize to the domain of face recognition. Two experiments were conducted, one using artificial faces and one using natural faces. Artificial faces were used to test memory for faces with discrete distinctive features while controlling the similarity of the faces themselves on more continuous dimensions. The natural-face experiment used the faces of 40 bald men categorized into three groups (typical, isolated, and distinctive) based on experimental ratings of distinctiveness. In both experiments, there were strong effects of the distinctive features on recognition performance. The data were accounted for reasonably well by a hybrid-similarity version of an exemplar recognition model (Nosofsky and Zaki, 2003), which includes a feature-matching mechanism that can provide boosts to an item's self-similarity. 相似文献
