ABSTRACTPrevious research has found that individuals vary greatly in emotion differentiation, that is, the extent to which they distinguish between different emotions when reporting on their own feelings. Building on previous work that has shown that emotion differentiation is associated with individual differences in intrapersonal functions, the current study asks whether emotion differentiation is also related to interpersonal skills. Specifically, we examined whether individuals who are high in emotion differentiation would be more accurate in recognising others’ emotional expressions. We report two studies in which we used an established paradigm tapping negative emotion differentiation and several emotion recognition tasks. In Study 1 (N?=?363), we found that individuals high in emotion differentiation were more accurate in recognising others’ emotional facial expressions. Study 2 (N?=?217), replicated this finding using emotion recognition tasks with varying amounts of emotional information. These findings suggest that the knowledge we use to understand our own emotional experience also helps us understand the emotions of others. 相似文献

Precession electron diffraction (PED) has been carried out on a fully ordered Fe–40at.%Al solid solution in order to explore its suitability for determining the state of order. The integrated intensity ratio of a superlattice reflection with respect to a fundamental reflection was measured as a function of the sample thickness and the results are well fitted by dynamical simulations. It is proposed that, in addition to conventional X-ray diffraction, PED may provide access to the state of order at microscopic and nanoscopic scales. 相似文献

Since the late nineties, computerized neurocognitive testing has become a central component of sport-related concussion (SRC) management at all levels of sport. In 2005, a review of the available evidence on the psychometric properties of four computerized neuropsychological test batteries concluded that the tests did not possess the necessary criteria to warrant clinical application. Since the publication of that review, several more computerized neurocognitive tests have entered the market place. The purpose of this review is to summarize the body of published studies on psychometric properties and clinical utility of computerized neurocognitive tests available for use in the assessment of SRC. A review of the literature from 2005 to 2013 was conducted to gather evidence of test-retest reliability and clinical validity of these instruments. Reviewed articles included both prospective and retrospective studies of primarily sport-based adult and pediatric samples. Summaries are provided regarding the available evidence of reliability and validity for the most commonly used computerized neurocognitive tests in sports settings. 相似文献

Gains in mobility, balance, and gait quality have been observed in clinical populations after treadmill training. In our laboratory, we introduce healthy adults to treadmill training programs in an effort to boost their adaptive generalization skills. We hypothesized that some individuals are more naturally predisposed to gait adaptation than others. Stride-time data from 20 healthy adults were collected while they walked on a laterally oscillating treadmill for the first time. We predicted that the more plastic adapters would rapidly synchronize their stride frequencies to the treadmill's oscillation frequency. A treadmill mounted on a 6-degrees-of-freedom motion base platform was programmed to move laterally in a continuous, sinusoidal pattern for 20 min while participants walked at 1.1 m/s. Twenty-five percent of our participants showed a prolonged uninstructed entrained response. Those who did not entrain were still able to adapt to the novel locomotor challenge by applying various alternative strategies. Although entrainment was not required for adaptation, we report compelling evidence that the frequency of the support-surface motion influenced the adapted strategies of 80% of our participants. 相似文献

Background and Objectives: This study evaluated the effectiveness of a web-based stress management program among community college students that focused on increasing perceived control over stressful events. Design: Students (N = 257) were randomly assigned to a Present Control Intervention or a Stress-information only comparison group. Methods: Primary outcomes were perceived stress and stress symptoms; secondary outcomes were depression and anxiety. Self-report measures were completed online at preintervention, postintervention, and three-week follow-up. Intervention effects were estimated using linear mixed models. Seventy-five percent of the sample (n = 194) completed the pretest and comprised the intent-to-treat sample. Results: Participants in the intervention group reported significant increases in present control, and significant decreases in all four primary and secondary outcome measures from baseline to postintervention and follow-up. Within-group effect sizes were small to medium at postintervention (mean d = –.34) and follow-up (mean d = –.49). The mean between-group effect size on the four outcome measures was d = .35 at postintervention but d = .12 at follow-up, due to unexpected decreases in distress in the comparison group. Conclusions: Our online program is a cost-effective mental health program for college students. Limitations and future direction are discussed. 相似文献

Abstract Obsessive-compulsive disorder (OCD) is a debilitating psychiatric condition with a heterogeneous array of obsessions and compulsions. Although factor analytic studies have identified symptom dimensions comprising the clinical presentation of OCD, many frequently reported miscellaneous symptoms are not considered in factor analytic studies because they do not fit conceptually within a particular symptom category, despite being functionally related. In the present study, we examined the associations between miscellaneous symptoms and OCD symptom dimensions in a sample of 111 adults with OCD. Overall, most miscellaneous symptoms were associated with one or more symptom dimensions in previously identified four- (14 of the 22 symptoms) and five-factor models (12 of the 22 symptoms). In both models, Contamination/Cleaning was the only dimension not related to any miscellaneous symptom. The present results provide information about which miscellaneous symptoms may be related to particular symptom dimensions, which will assist in clinical evaluations and help planning behavioral psychotherapy (e.g., hierarchy development). 相似文献
