The global neuronal workspace theory [Dehaene, S., & Naccache, L. (2001). Towards a cognitive neuroscience of consciousness: basic evidence and a workspace framework. Cognition, 79, 1–37.] proposes that it is impossible for an unconscious stimulus to be used strategically to enhance task performance (bottom–up effect), while a fully consciously perceived stimulus can be used to improve task performance (top–down effect). Two experiments were designed to investigate these hypotheses. In a first experiment we investigated whether a manipulation of the proportion of Arabic/number word targets had a top–down effect. Since the subjects were fully aware of the target, we expected that this manipulation could be used to enhance task performance. In a second experiment we determined whether a manipulation of the proportion of Arabic/number word primes had a bottom–up effect. Since the subjects were unaware of the prime, we hypothesized that they would be unable to use the manipulation to enhance task performance and therefore the manipulation would have no effect. Both hypotheses were largely confirmed. 相似文献

The present research examined how procedural fairness predicts negative emotions and withdrawal behavior as a function of authority's display of passion. A first study revealed that reinforcing the concept of passion made the concept of justice and fairness more accessible to participants, as such suggesting that authority passion should make people focus more on procedural fairness information. Corroborating this line of reasoning, a scenario experiment and a laboratory experiment thereafter yielded consistent evidence that the effects of procedural fairness (i.e., voice vs. no voice) were stronger on negative emotions and willingness to withdraw when the authority was passionate relative to not being passionate. In addition, the results of both studies also revealed that negative emotions mediated the effect of procedural fairness on withdrawal, but only so when the authority was passionate (i.e., mediated moderation). It is concluded that more research is needed focusing on the interactions between different authority styles/characteristics and procedural fairness effects.

The purpose of this prospective study was to examine whether explicit and implicit vulnerability associations before and after trauma exposure predict the onset and persistence of post-traumatic stress disorder (PTSD) symptoms. The implicit association test (IAT) was modified to assess associations of self with vulnerability related cues. Dutch soldiers completed the IAT 6 weeks before being deployed to Iraq, and again 5 months upon return home. They also rated an explicit vulnerability scale. PTSD symptoms were assessed 5 and 15 months after deployment with a clinical interview and questionnaire. The results showed that (1) the pre-deployment vulnerability measures did not predict PTSD symptoms at 5 months, (2) both explicit and implicit post-deployment vulnerability measures explained unique variance in concurrent PTSD symptoms, over and above pre-existing neuroticism, and (3) only the explicit post-deployment vulnerability measure predicted unique variance in later PTSD symptoms (at 15 months), after controlling for earlier symptoms. This was no longer the case after controlling for neuroticism. The results suggest that strong implicit associations between the self and vulnerability are a consequence rather than a cause of PTSD symptoms. 相似文献

The most familiar emotional signals consist of faces, voices, and whole-body expressions, but so far research on emotions expressed by the whole body is sparse. The authors investigated recognition of whole-body expressions of emotion in three experiments. In the first experiment, participants performed a body expression-matching task. Results indicate good recognition of all emotions, with fear being the hardest to recognize. In the second experiment, two alternative forced choice categorizations of the facial expression of a compound face-body stimulus were strongly influenced by the bodily expression. This effect was a function of the ambiguity of the facial expression. In the third experiment, recognition of emotional tone of voice was similarly influenced by task irrelevant emotional body expressions. Taken together, the findings illustrate the importance of emotional whole-body expressions in communication either when viewed on their own or, as is often the case in realistic circumstances, in combination with facial expressions and emotional voices. 相似文献

Self-schema and social comparison explanations of body dissatisfaction: a laboratory investigation 总被引:1,自引:1,他引:0
The current study was an investigation of the self-schema and social comparison theories of body dissatisfaction. The social comparison manipulation consisted of exposure to one of three levels of comparison figure: upward, downward, or no comparison. Two different imagery exercises served to prime either a participants’ appearance self-schema, or a non-appearance schema. Participants completed state measures of body image and mood at pre- and posttest. Results indicated no significant interaction between priming and social comparison and no significant main effect for priming. However, there was a significant effect of social comparison, such that those in the downward comparison condition showed an increase in body satisfaction and positive mood. Results are discussed in the context of self-schema theory and social comparison, and suggestions are given for future research that might further shed light on these theoretical approaches for understanding body dissatisfaction. 相似文献

This work examines differences between female borderline patients with and without substance abuse problems and between borderline patients from different treatment settings. A total of 64 female borderline patients were recruited from mental health services (n = 34) and addiction treatment services (n = 20); 35 had a substance abuse problem. Patient groups were compared with regard to both clinical and etiological factors using multivariate analysis of variance for 47 continuous variables and logistic regression for 15 dichotomous variables. Borderline patients with substance abuse problems reported less hostility, suspicion, and anger but more anxiety, insufficiency, and suicide attempts. Patients from addiction treatment services reported less avoidant and more antisocial behavior. The differences between borderline patients with and without substance abuse problems are limited in number and size. Therefore, there is no empirical justification for the exclusion of borderline patients with substance abuse problems from general treatment services or clinical trials. 相似文献

Although auditory distractions are prevalent and often seen as a threat to performance, relatively few studies have explored distraction effects in an applied sport context. This field experiment examined expert golfers' (n = 36) competitive performance in a normal and a distracting condition. The results displayed similar performance in the two conditions. Participants' responses to a postcompetition questionnaire generally suggested that they found auditory distractions below moderately disturbing and detrimental to their performance. Overall, our results contradict the popular consensus that distractions are disturbing and detrimental in motor performance contexts. 相似文献
