Data from a large survey of 1,561 professionals were used to examine the relationship between power and infidelity and the process underlying this relationship. Results showed that elevated power is positively associated with infidelity because power increases confidence in the ability to attract partners. This association was found for both actual infidelity and intentions to engage in infidelity in the future. Gender did not moderate these results: The relationship between power and infidelity was the same for women as for men, and for the same reason. These findings suggest that the common assumption (and often-found effect) that women are less likely than men to engage in infidelity is, at least partially, a reflection of traditional gender-based differences in power that exist in society. 相似文献

Anxiety is typically considered an impediment to cognition. We propose anxiety-related impairments in cognitive-behavioral performance are the consequences of enhanced stimulus-driven attention. Accordingly, reflexive, habitual behaviors that rely on stimulus-driven mechanisms should be facilitated in an anxious state, while novel, flexible behaviors that compete with the former should be impaired. To test these predictions, healthy adults (N=17) performed a mixed-saccade task, which pits habitual actions (pro-saccades) against atypical ones (anti-saccades), under anxiety-inducing threat of shock and safe conditions. Whole-head magnetoencephalography (MEG) captured oscillatory responses in the preparatory interval preceding target onset and saccade execution. Results showed threat-induced anxiety differentially impacted response times based on the type of saccade initiated, slowing anti-saccades but facilitating erroneous pro-saccades on anti-saccade trials. MEG source analyses revealed that successful suppression of reflexive pro-saccades and correct initiation of anti-saccades during threat was marked by increased theta power in right ventrolateral prefrontal cortical and midbrain regions (superior colliculi) implicated in stimulus-driven attention. Theta activity may delay stimulus-driven processes to enable generation of an anti-saccade. Moreover, compared to safety, threat reduced beta desynchronization in inferior parietal cortices during anti-saccade preparation but increased it during pro-saccade preparation. Differential effects in inferior parietal cortices indicate a greater readiness to execute anti-saccades during safety and to execute pro-saccades during threat. These findings suggest that, in an anxiety state, reduced cognitive-behavioral flexibility may stem from enhanced stimulus-driven attention, which may serve the adaptive function of optimizing threat detection. 相似文献

According to the Proust phenomenon, olfactory memory triggers are more evocative than other-modality triggers resulting in more emotional and detailed memories. An experimental paradigm was used to investigate this in aversive memories, similar to those experienced by patients with posttraumatic stress disorder. Seventy healthy participants watched an aversive film, while simultaneously being exposed to olfactory, auditory and visual triggers, which were matched on intensity, valence, arousal and salience. During a second session one week later, participants were randomly exposed to one of the three triggers, and asked to think back about the film and to rate the resulting memory. Results revealed that odour-evoked memories of aversive events were more detailed, unpleasant and arousing than memories evoked by auditory, but not visual, triggers. 相似文献

The time-course of changes in vividness and emotionality of unpleasant autobiographical memories associated with making eye movements (eye movement desensitisation and reprocessing, EMDR) was investigated. Participants retrieved unpleasant autobiographical memories and rated their vividness and emotionality prior to and following 96 seconds of making eye movements (EM) or keeping eyes stationary (ES); at 2, 4, 6, and 10 seconds into the intervention; then followed by regular larger intervals throughout the 96-second intervention. Results revealed a significant drop compared to the ES group in emotionality after 74 seconds compared to a significant drop in vividness at only 2 seconds into the intervention. These results support that emotionality becomes reduced only after vividness has dropped. The results are discussed in light of working memory theory and visual imagery theory, following which the regular refreshment of the visual memory needed to maintain it in working memory is interfered with by eye movements that also tax working memory, which affects vividness first. 相似文献

The corpus callosum (CC) is the largest white matter tract in the brain. It enables interhemispheric communication, particularly with respect to bimanual coordination. Here, we use diffusion tensor imaging (DTI) in healthy humans to determine the extent to which structural organization of subregions within the CC would predict how well subjects learn a novel bimanual task. A single DTI scan was taken prior to training. Participants then practiced a bimanual visuomotor task over the course of 2 wk, consisting of multiple coordination patterns. Findings revealed that the predictive power of fractional anisotropy (FA) was a function of CC subregion and practice. That is, FA of the anterior CC, which projects to the prefrontal cortex, predicted bimanual learning rather than the middle CC regions, which connect primary motor cortex. This correlation was specific in that FA correlated significantly with performance of the most difficult frequency ratios tested and not the innately preferred, isochronous frequency ratio. Moreover, the effect was only evident after training and not at initiation of practice. This is the first DTI study in healthy adults which demonstrates that white matter organization of the interhemispheric connections between the prefrontal structures is strongly correlated with motor learning capability. 相似文献

Despite the importance of health information seeking, not all people engage in such behaviors, especially when thinking about the disease is distressing. The focus of this paper is to examine the antecedents of information seeking and retention. Based on individuals’ risk perception and efficacy beliefs, the risk perception attitude framework is used to formulate four groups: responsive (high risk, high efficacy), avoidance (high risk, low efficacy), proactive (low risk, high efficacy), and indifference (low risk, low efficacy). In Study 1, a 2 (risk) × 2 (efficacy) between‐subjects experiment, participants’ perceived risk to skin cancer and skin cancer–related efficacy beliefs were induced to determine their information seeking, retention, and intentions to engage in future seeking. The responsive group, as predicted, was associated with the most information‐seeking behaviors and information‐seeking intentions. The avoidance group, however, sought information but exhibited the lowest retention scores. These results were used to derive two predictions—the incredulity hypothesis and the anxiety‐reduction hypothesis—that were then tested in Study 2. Study 2, also a 2 (risk) × 2 (efficacy) between‐subjects experiment dealing with diabetes, found support for the anxiety‐reduction hypothesis, which argues that the high‐risk, low‐efficacy group experiences more anxiety, which leads to high motivations to seek, but lower ability to retain information. 相似文献

ABSTRACTThe philosophical foundations of interpretative phenomenological analysis (IPA)—phenomenology, hermeneutics, and idiography—guide its practice and use. However, this foundation is often at odds with cultural practices of disciplines that value post-positivist perspectives emphasizing that reality can be objectively known. The conflict between the philosophical underpinnings of the methodology and the cultural practices of particular disciplines can serve to limit the use and acceptance of IPA. This article highlights ways researchers can use IPA even when the underlying tenets of that methodological approach may be in conflict with disciplinary norms. As such, we have set out to explore the tensions that accompany the choice to use IPA in the context of engineering education research within the United States. As a group of engineering education researchers, we drew upon collaborative inquiry to systematically examine our use of IPA. Our exploration of using IPA, as connected to everyday practice in a discipline that takes a postpositivist stance toward knowledge generation, provides examples for the use of IPA in tension with these disciplinary norms. 相似文献
