Two experiments evaluated differential predictions from two cognitive formulations of anxiety. According to one view, attentional biases for threat reflect vulnerability to anxiety; and as threat inputs increase, high trait anxious individuals should become more vigilant, and low trait individuals more avoidant, of threat (Williams, Watts, MacLeod, & Mathews, 1988, 1997). However, according to a “cognitive-motivational” view, trait anxiety influences the appraisal of stimulus threat value, rather than the direction of attentional bias, and both high and low trait anxious individuals should exhibit greater vigilance for high rather than mild threat stimuli (Mogg & Bradley, 1998). To test these predictions, two experiments examined the effect of manipulating stimulus threat value on the direction of attentional bias. The stimuli included high threat and mild threat pictorial scenes presented in a probe detection task. Results from both studies indicated a significant main effect of stimulus threat value on attentional bias, as there was increased vigilance or reduced avoidance of threat, as threat value increased. This effect was found even within low trait anxious individuals, consistent with the “cognitive-motivational” view. Theoretical and clinical implications are discussed.  相似文献

In this article, we present results from an interdisciplinary research project aimed at assessing consciousness in dreams. For this purpose, we compared lucid dreams with normal non-lucid dreams from REM sleep. Both lucid and non-lucid dreams are an important contrast condition for theories of waking consciousness, giving valuable insights into the structure of conscious experience and its neural correlates during sleep. However, the precise differences between lucid and non-lucid dreams remain poorly understood. The construction of the Lucidity and Consciousness in Dreams scale (LuCiD) was based on theoretical considerations and empirical observations. Exploratory factor analysis of the data from the first survey identified eight factors that were validated in a second survey using confirmatory factor analysis: INSIGHT, CONTROL, THOUGHT, REALISM, MEMORY, DISSOCIATION, NEGATIVE EMOTION, and POSITIVE EMOTION. While all factors are involved in dream consciousness, realism and negative emotion do not differentiate between lucid and non-lucid dreams, suggesting that lucid insight is separable from both bizarreness in dreams and a change in the subjectively experienced realism of the dream.  相似文献

The capacity of psychosocial stressors to provoke the hypothalamic–pituitary–adrenal axis has been demonstrated to vary depending upon a number of psychological factors. Laboratory stressors characterized by social-evaluative threat are proposed to be the most efficacious in the elicitation of a cortisol stress response. Salivary cortisol, cardiovascular, and subjective responses of 16 healthy adults facing a naturalistic stressor characterized by social-evaluative threat (competitive performance auditions) were examined. Audition exposure was sufficient to provoke significant cortisol, arterial blood pressure (systolic and diastolic), and subjective stress responses. Cortisol response reactivity (area under the curve with respect to increase [AUCi]) also correlated with participants' subjective rating of social-evaluative threat. The competitive performance audition context is therefore considered a promising context in which to further explore cortisol responsivity to social-evaluative threat.  相似文献

Abstract

This study seeks to validate the Spanish version of the Dyadic Coping Inventory (DCI) in a Latino population with data from 113 heterosexual couples. Results for both partners confirm the factorial structure for the Spanish version (Subscales: Stress Communication, Emotion- and Problem-Focused Supportive, Delegated, and Negative Dyadic Coping, Emotion- and Problem-Focused Common Dyadic Coping, and Evaluation of Dyadic Coping; Aggregated Scales: Dyadic Coping by Oneself and by Partner) and support the discriminant validity of its subscales and the concurrent, and criterion validity of the subscales and aggregated scales. These results do not only indicate that the Spanish version of the DCI can be used reliably as a measure of coping in Spanish-speaking Latino couples, but they also suggest that this group relies on dyadic coping frequently and that this type of coping is associated with positive relationship functioning and individual coping. Limitations and implications are discussed.  相似文献

A recent study of the override and update operations defined on sets of partial functions placed both operations within the algebraic context of a certain variety of algebras. We show the latter to be term equivalent to the variety of right-handed skew Boolean algebras. Both operations are then studied within the broader context of skew lattices with an eye towards achieving greater insight into their joint algebraic behavior. A decision procedure is given to determine whether an equation in both operations holds for all sets of partial functions.  相似文献

Two experiments investigated the determinants of performance on a go/no-go task by studying the interplay of two executive function components, working memory (WM) and inhibition. Systematically varied task demands on WM and inhibition were used in the analysis of performance together with individual capacity measures of both functions, thereby investigating an interactive view of WM and inhibition. Further analyses were conducted with individual differences in general fluid intelligence (gF), in an attempt to study the role of higher order cognition in handling task demands. The results are new in presenting empirical evidence for interactive effects of the task demand variables in concert with individual WM capacity as well as with gF, suggesting that executive processes common to WM and gF are involved in inhibitory performance, whereas gF appears to reflect a broader function in controlling behaviour in relation to task goals, whether it involves active responding or not.  相似文献

ABSTRACT

The Holy and Great Council of the Orthodox Church (2016) was supposed to be, above all, a demonstration of Orthodox unity. However, four autocephalous Orthodox churches were absent and others were split internally over their stances towards the Council. Ethnophyletism (ecclesiastical nationalism) and disagreements between the Orthodox churches over universal primacy have often been emphasised as the factors which eventually prevented the display of full pan-Orthodox conciliarity. By analysing official documents of the Serbian Orthodox Church (SOC) and the statements of Serbian hierarchs, I assess the role of ethnophyletism and primacy in the SOC’s positioning regarding the Council. I conclude that ethnophyletism and a lack of consensus over primacy were overshadowed by the cleavage between progressive and conservative tendencies within the SOC as well as beyond autocephalous frontiers. The study may thus contribute to a better understanding of the current challenges to pan-Orthodox conciliarity in general.  相似文献

To ensure successful implementation of genetic screening and counselling according to patients best interests, the attitudes and motives of the public are important to consider. The aim of this study was to apply a theoretical framework in order to investigate which individual and disease characteristics might facilitate the uptake of genetic testing. A questionnaire using an extended version of the Theory of Planned Behaviour was developed to assess the predictive value of affective and cognitive expected outcomes, subjective norms, perceived control and uncertainty avoidance on the intention to undergo genetic testing. In addition to these individual characteristics, the predictive power of two disease characteristics was investigated by systematically varying the diseases fatality and penetrance (i.e. the probability of getting ill in case one is a mutation carrier). This resulted in four versions of the questionnaire which was mailed to a random sample of 2400 Norwegians. Results showed genetic test interest to be quite high, and to vary depending on the characteristics of the disease, with participants preferring tests for highly penetrant diseases. The most important individual predictor was uncertainty avoidance.  相似文献

This paper investigates the moderating role of specific Big Five personality traits on the relationship between learner control and training performance in an e-learning environment. Specifically, we examined the role of openness to experience, conscientiousness, and extraversion. Participants completed a video-based e-learning program with either a high or low level of learner control. Results demonstrated that the personality traits of openness to experience and extraversion moderated the relationship between learner control and training performance. Specifically, training performance was higher for trainees higher in openness and extraversion when they were in an environment with high learner control versus low learner control. Conversely, for trainees lower in these traits, performance was higher with low learner control versus high learner control. Future research and practical applications are discussed.  相似文献

Videogames are emerging as an increasingly popular training tool in the military. Given this trend, it is important to investigate factors that maximize the effectiveness of this training medium. The present research analyzed the impact of trainee attributes (i.e., prior videogame experience, videogame self-efficacy, and goal orientation) on game-based training outcomes. Participants completed a game–based tactics training exercise. The training exercise used America's Army, a first-person-perspective videogame with a single-player section to introduce game-specific tasks, followed by a multiplayer section where participants form small teams to conduct collaborative missions. Prior to and after the training exercise, participants completed online questionnaires. Results suggest that the trainee attributes, as a set, had a positive impact on trainee motivation, trainee satisfaction, ease in using the training game interface, metacognitive strategies utilized during training, and time spent engaging in the training game. These findings have implications for instructors using videogames as training tools. Recommendations for future research in this area are provided.  相似文献
