This study examined a representative sample of academically gifted (N = 374) and non-gifted (N = 428) Israeli high-school students in order to compare these different student populations on the Big-Five and adaptive outcomes. Consistent with prior research, gifted students scored higher than non-gifted peers on Openness to Experience but scored lower on Neuroticism. In addition, gifted students scored lower on state anxiety facets and were not reliably different from their nongifted counterparts on mental distress or subjective well being. Overall, the empirical data are consistent with recent research suggesting that when gifted students are compared with nongifted students on various socio-emotional and personality characteristics, the results are not unfavorable to gifted students.  相似文献

Virtual reality (VR) has created opportunities to innovatively re-imagine the way we examine the relations between pressure, competition anxiety and performance. This study aimed to determine the efficacy of VR as a means of measuring the effects of competition anxiety when pressure manipulations are applied while participants bat in a cricket batting VR simulator. The twenty-eight male participants who took part in two experiments were divided into a high (14, mean age: 22.94, SD: 5.4) and a low skill group (14; mean age: 23.55, SD: 9.9). The aim of the first experiment was to validate the VR simulator as a tool that could capture differences in batting performance between a high and low skilled group. The results showed that high skill participants not only scored significantly higher run rates than low skill participants, but they outperformed the low skill group in all performance measures including higher incidences of correct foot placements that reflect better anticipatory responses. Having established the VR batting simulator as being a reliable tool for capturing batting dynamics, experiment 2 aimed to explore the effects of a pressure manipulation on competition anxiety and batting performance. All measures of competition anxiety were significantly greater for both groups in the high-pressure condition compared to the two low-pressure conditions (p < 0.001). The magnitude of this effect was greater in the low skill group for cognitive (0.59) and somatic (0.794) anxiety. Despite anxiety levels significantly increasing in the high-pressure condition, no significant negative changes to batting performance were found for either group, with both groups actually demonstrating performance improvements. Overall, the findings show how a cricket batting virtual reality simulator can be used as a tool to measure the effects of pressure on competition anxiety and batting performance in tasks involving dynamic skill execution.  相似文献

It has long been recognised that depression and anxiety share a common core of negative affect, but research on similarities and differences between these two emotions is growing. The focus of the current study was on whether the timing of a triggering event can determine whether the dominant emotional reaction is depression or anxiety. It was hypothesised that aversive events in the past would elicit more depression than anxiety, whereas the same aversive events in the future would elicit more anxiety than depression. We created temporally varied versions of vignettes describing aversive events occurring at either time, and asked participants to rate the extent to which the events would elicit feelings of depression or anxiety. Results indicated that adverse past events elicited much higher ratings of anticipated depression and adverse future events elicited much higher ratings of anticipated anxiety. Implications for understanding these two emotions and depressive and anxiety disorders are discussed.  相似文献

Adolescent school absenteeism is associated with negative outcomes such as conduct disorders, substance abuse, and dropping out of school. Mental health factors, such as depression and anxiety, have been found to be associated with increased absenteeism from school. Sexual minority youth (youth who are attracted to the same sex or endorse a gay, lesbian, or bisexual identity) are a group at risk for increased absenteeism due to fear, avoidance, and higher rates of depression and anxiety than their heterosexual peers. The present study used longitudinal data to compare sexual minority youth and heterosexual youth on excused and unexcused absences from school and to evaluate differences in the relations between depression and anxiety symptoms and school absences among sexual minority youth and heterosexual youth. A total of 108 14- to 19-years-old adolescents (71% female and 26% sexual minority) completed self-report measures of excused and unexcused absences and depression and anxiety symptoms. Compared to heterosexual youth, sexual minority youth reported more excused and unexcused absences and more depression and anxiety symptoms. Sexual minority status significantly moderated the effects of depression and anxiety symptoms on unexcused absences such that depression and anxiety symptoms were stronger predictors of unexcused absences for sexual minority youth than for heterosexual youth. The results demonstrate that sexual minority status and mental health are important factors to consider when assessing school absenteeism and when developing interventions to prevent or reduce school absenteeism among adolescents.  相似文献

People with anxiety disorders show an attentional bias towards threat or negative emotion words. This exploratory study examined whether people who stutter (PWS), who can be anxious when speaking, show similar bias and whether reactions to threat words also influence speech motor planning and execution. Comparisons were made between 31 PWS and 31 fluent controls in a modified emotional Stroop task where, depending on a visual cue, participants named the colour of threat and neutral words at either a normal or fast articulation rate. In a manual version of the same task participants pressed the corresponding colour button with either a long or short duration. PWS but not controls were slower to respond to threat words than neutral words, however, this emotionality effect was only evident for verbal responding. Emotionality did not interact with speech rate, but the size of the emotionality effect among PWS did correlate with frequency of stuttering. Results suggest PWS show an attentional bias to threat words similar to that found in people with anxiety disorder. In addition, this bias appears to be contingent on engaging the speech production system as a response modality. No evidence was found to indicate that emotional reactivity during the Stroop task constrains or destabilises, perhaps via arousal mechanisms, speech motor adjustment or execution for PWS.Educational objectives: The reader will be able to: (1) explain the importance of cognitive aspects of anxiety, such as attentional biases, in the possible cause and/or maintenance of anxiety in people who stutter, (2) explain how the emotional Stroop task can be used as a measure of attentional bias to threat information, and (3) evaluate the findings with respect to the relationship between attentional bias to threat information and speech production in people who stutter.  相似文献

Anxiety and depression frequently co-occur and may share similar deficits in the processing of emotional stimuli. High anxiety is associated with a failure in the acquisition and extinction of fear conditioning. Despite the supposed common deficits, no research has been conducted on fear acquisition and extinction in depression. The main aim of the present study was to investigate and compare fear acquisition and extinction in anxiety- and depression-prone participants. Non-clinical anxious, depressive, anxious-depressive and control participants performed a fear discrimination task. During acquisition, the CS+ predicted an aversive event (unconditioned stimulus, US) and the CS? safety (no US). During extinction, the CS+ was no longer followed by the US, rendering it (temporarily) into a safety signal. On each CS participants rated their US expectancy; skin conductance responses (SCRs) were measured throughout. The expectancy scores indicated that high anxiety resulted in less safety learning during acquisition and extinction; no effect of depression was observed. SCRs showed that high-anxiety persons displayed less discrimination learning (CS+ minus CS?) during acquisition than low-anxiety persons. During extinction, high-depression persons demonstrated more discriminative SCR than low-depression persons. The observed discrepancies in response patterns of high-anxiety and -depression persons seem to indicate distinctive information processing of emotional stimuli.  相似文献

Several recent studies have investigated relationships between post-traumatic stress disorder (PTSD) and learning and memory problems. These reports have found in general that not only does PTSD affect trauma-related memories, but when patients with PTSD are compared with similar trauma patients without PTSD, general memory impairments have been found. The present paper reports a study in which associative learning, using Pavlovian eyeblink conditioning, was investigated in combat veterans with and without chronic PTSD, using interstimulus intervals of 500 and 1000 msec in two separate experiments. Although several recent reports suggest that larger-magnitude autonomic conditioned responses occur in patients with PTSD during Pavlovian conditoning, the present study found evidence of impaired Pavlovian eyeblink conditioning in combat veterans with and without PTSD, compared to non-combat veterans. Although these data suggest that combat leads to an impaired associative learning process regardless of whether PTSD is apparent, a group of community-dwelling combat veterans not under medical treatment showed normal conditioning, suggesting that variables other than prior combat must also be involved.  相似文献

Bicycles are an environmentally-friendly, energy-saving mode of transportation. Public bike-and-ride is a term used to describe the use of public bicycles combined with transit as a means of transportation. A new stated preference (SP) design scheme based on the factors respondents felt were most important was proposed to augment the traditional SP design under complex multi-factor and multi-level situations. iPads were used to automatically administer the survey under each design scheme and collect the choice behavior data for public bike-and-ride. The concept of perceived psychological distance was further proposed and used to estimate Logit models. Comparative analysis of these models shows for the traditional SP design scheme, some factors, including perceived psychological distance, have reduced statistically significant effects on public bike-and-ride choice relative to the new SP design scheme. This indicates that in scenarios with complex decisions, the decision-makers would reduce their consideration of some factors and simplify their decision process making the new SP survey design scheme more suitable to analyze their choice behavior in those cases. Model analysis showed that perceived psychological distance for each traveler is the most critical factor during the decision process for travel behavior analysis. Finally, sensitivity analysis was conducted to determine which factors in the new survey design were important to increase the share of public bike-and-ride users. Practical findings for promoting public bike-and-ride use are presented in addition to theoretical references for improving the traditional survey methods.  相似文献

The purpose of the present study was to examine anxiety sensitivity, attentional bias to threat (ABT), and the aggregate influence of these constructs as prospective predictors of anxiety. Participants (N = 176) completed a baseline assessment session which included the completion of self-report measures of anxiety and anxiety sensitivity, as well as an eye-tracking task in which eye movements were recorded during the viewing of neutral and threat images. Measures of anxiety and anxiety sensitivity were completed again as part of an online questionnaire battery at a 1-year follow-up session. As predicted, baseline anxiety sensitivity and ABT predicted anxiety at 1-year follow-up even after accounting for baseline anxiety. However, these main effects were qualified by a significant interaction effect such that those high in anxiety sensitivity at baseline reported relatively higher anxiety at the 1-year follow-up, but only if they also exhibited higher levels of ABT at baseline. Results suggest that individuals with this combination of vulnerability factors (high levels of both anxiety sensitivity and ABT) may be at particularly high risk for developing anxiety and may benefit from preemptive efforts to reduce ABT.  相似文献
