In attentional bias modification programs, individuals are trained to attend away from threat in order to reduce emotional reactivity to stressful situations. However, attending towards threat is considered to be a prerequisite for fear reduction in other models of anxiety. We compared both views by manipulating attention towards or away from an acquired signal of threat. The strength of extinction and reacquisition was assessed with threat and US-expectancy ratings. We found more extinction in the attend towards threat group, compared to both the attend away from threat group and a control group in which attention was not manipulated. The results are in line with the Emotional Processing Theory and cognitive accounts of classical conditioning.  相似文献

Ribeiro, L. A. & Fearon, P. (2010). Theory of mind and attentional bias to facial emotional expressions: A preliminary study. Scandinavian Journal of Psychology. Theory of mind ability has been associated with performance in interpersonal interactions and has been found to influence aspects such as emotion recognition, social competence, and social anxiety. Being able to attribute mental states to others requires attention to subtle communication cues such as facial emotional expressions. Decoding and interpreting emotions expressed by the face, especially those with negative valence, are essential skills to successful social interaction. The current study explored the association between theory of mind skills and attentional bias to facial emotional expressions. According to the study hypothesis, individuals with poor theory of mind skills showed preferential attention to negative faces over both non‐negative faces and neutral objects. Tentative explanations for the findings are offered emphasizing the potential adaptive role of vigilance for threat as a way of allocating a limited capacity to interpret others’ mental states to obtain as much information as possible about potential danger in the social environment.  相似文献

Managers often must assess singular strategic options. Four studies of such assessments demonstrate a tunnel vision effect: Focal managerial options often are favored in an evidentially unjustifiable manner. Study 1 concerns new product development, and demonstrates that a prototype that has become focal tends to be judged overly favorably, and is chosen for launch with unwarranted enthusiasm. Study 2 shows that this tunnel vision effect generalizes to judgments and decisions about general strategy. Study 3 focuses on the information search patterns underlying the effect, and Study 4 replicates the tunnel vision effect among experienced executives, and demonstrates the utility of a debiasing procedure. Data in all of the studies implicate selective processing as the driver of the tunnel vision effect, and further understanding of how selective processing affects choice. Several alternative operationalizations of the empirically tested debiasing procedure are discussed.  相似文献

关于低出生体重儿生长模式的思考   总被引:2,自引:0,他引:2  
低出生体重儿发生率是衡量社会发展和妇幼保健状况的重要指标。低出生体重不仅直接增加新生儿死亡率和儿童早期的患病率,而且与儿童的远期预后密切相关。本文从低出生体重儿的生长特点、生长追赶的利弊以及营养管理等方面,探讨适于低出生体重儿的最佳生长模式,以求改善这一特殊群体的近期健康和远期生活质量。  相似文献

Attentional bias for threat has been implicated in the contamination fear (CF) subtype of obsessive-compulsive disorder, but the components of the bias (facilitated attention versus difficulty in disengagement) and the stage of processing during which the bias occurs (early versus late stage of processing) remains unclear. Further, it is unclear whether attentional biases in CF are towards fear or disgust-related stimuli. The present study examined attentional biases in a group of individuals selected to have elevated CF (n = 23) and a control group (n = 28) using the spatial cueing task. Stimuli were neutral, disgusting, or frightening pictures presented for either 100 or 500 ms. Results revealed evidence for delayed disengagement from both fear and disgust stimuli in the CF group, but not in the control group. The effect appeared to be greater at 500 ms stimulus presentation, but did not appear to differ between fear and disgust stimuli. The CF group was associated with delayed disengagement from threat even when controlling for generic response slowing. Theoretical and clinical implications are discussed.  相似文献

Informed by social identity theory, we developed a model to examine the antecedents and consequences of perceptions of personal gender discrimination. In the model, gender, gender identity, and perceived gender bias against women are considered as salient predictors of perceived personal gender discrimination, and organizational commitment and intentions to leave are considered as the outcome variables. Structural equation modeling (SEM) was used to analyze the data collected from a sample of practicing solicitors in Hong Kong. We found that (a) women perceived more personal gender discrimination and gender bias against women than did men, (b) gender moderated the relationship between perceived gender bias against women and perceived personal gender discrimination, (c) the positive effect of gender bias against women on gender discrimination was more strongly positive for women than for men, and (d) perceived personal gender discrimination affected organizational commitment and intentions to leave. Theoretical and practical implications are discussed.  相似文献

Despite significant advancements in the research of subjective well-being (SWB), little is known about its connection with basic cognitive processes. The present study explores the association between selective attention to emotional stimuli (i.e. emotional faces) and both the emotional and cognitive components of SWB (i.e. emotional well-being and satisfaction in life, respectively). Participants (N?=?83) were asked to freely watch a series of 84 pairs of emotional (happy, angry, or sad) and neutral faces from the Karolinska Directed Emotional Faces database. Eye-tracking methodology measured first fixations, number of fixations, and the time spent looking at emotional faces. Results showed that both the emotional and cognitive components of SWB were related to a general bias to attend to happy faces and avoid sad faces. Yet, bootstrapping analyses showed that positive emotions, rather than life satisfaction, were responsible for the positive information-processing bias. We discuss the potential functionality of these biases and their implications for research on positive emotions.  相似文献

Objective: Attrition is a common problem in health behaviour change (HBC) trials. When the degree of attrition differs between treatment conditions, then this is called differential attrition and is regarded as a major threat to internal validity. The primary research question of this study was: how often and to what degree does differential attrition occur in HBC trials?

Design: A systematic review and meta-analysis of a random selection of HBC trials (k = 60). We meta-analysed the relative attrition rates using a random-effects model and examined the relationship between the relative attrition rates and the potential moderators: the amount of human contact in delivery and the intensity of the intervention/control condition, the type of control condition, and the follow-up intensity and duration.

Main outcome measures: Relative attrition rates.

Results: The average attrition rate was 18% (SD = .15; M = .15) in the intervention and 17% (SD = .13; M = .13) in the control conditions. The estimated average relative attrition rate was 1.10 (95% CI: 1.01–1.20, p = .02), suggesting an overall higher attrition rate of 10% in the intervention conditions. This relative attrition rate was not related to any of the potential moderators.

Conclusion: There is indication of a slightly higher amount of attrition on average in the intervention conditions of HBC trials.  相似文献
