Characteristically arising in response to overwhelmingly terrifying events, post-traumatic stress disorder (PTSD) is a disorder of memory: sufferers seemingly relive their trauma in the form of involuntary recollection. Prominent cognitive abnormalities, especially in memory functioning, have motivated research designed to elucidate the mediating mechanisms that produce PTSD symptoms, especially those involving involuntary recollection. Recent developments suggest a pathophysiological model of PTSD which includes hyporesponsive prefrontal cortical regions and/or a hyper-responsive amygdala. Other work has also identified above-average cognitive ability as a protective factor and below-average hippocampal volume as a vulnerability factor for PTSD among the trauma-exposed. These attempts to elucidate the mediating mechanisms of PTSD have been both cognitive and, more recently, cognitive-neuroscientific in emphasis. 相似文献

In this qualitative study the authors examine the Scriptural images that 10 Lutheran pastors employed in describing the ethical challenges in the pastor-congregant relationship. The analysis of Scriptural images is part of a larger study on pastors' experiences of a mandatory workshop, "Crossing the Boundaries (CTB),"which is required of Evangelical Lutheran Church in Canada (ELCIC) seminarians. The pastors' images were analyzed from the four perspectives of depth psychology, theology, social ethics, and sociology. In commenting on tensions in the pastors' Scriptural images the authors note commonalities among the four theoretical perspectives and discuss implications for practice and future research. 相似文献

It has been shown in previous work [Action figures and men. Sex Roles 53, 877–885] that male participants who handled extremely muscular action figures had lower body esteem than those who did not handle action figures or a Ken doll. However, the internal mechanisms that dictated this effect are unclear. Therefore, the current study extended this previous work by having male participants handle action figures of varying muscularity and completing a lexical decision task with target words that consisted of both positive and negative body words and feeling words in order to determine if males would be primed to think negatively about their bodies and self or if positive thoughts about their bodies and self would be interfered with. The results show that those participants who handled the extremely muscular action figures responded significantly more slowly to feeling positive words (e.g., content, confident) and marginally more slowly to body positive words (e.g., muscle, bicep) than those who did not handle any action figures. Overall, this suggests that the interference of positive words, not the priming of negative words, is the internal mechanism that produces the decreased body image satisfaction after exposure to muscular stimuli. Implications and future research are discussed. 相似文献

Preference reversals are diminished when gambles are presented as relative frequencies 总被引:1,自引:0,他引:1
Tunney RJ 《Quarterly journal of experimental psychology (2006)》2006,59(9):1516-1523
Preference reversals are a well-documented example of suboptimal decision making. Typical preference reversals experiments have involved monetary bets presented in probability format. Research on other examples of decision making have shown that irrational or suboptimal choices are diminished or eliminated entirely when the probabilities are presented as relative frequencies (e.g., Gigerenzer & Hoffrage, 1995). The aim of the present experiment was to determine if the way in which information is presented to participants affects participants' preferences. When the options were presented in the standard probability format 59% of participants' preferences were reversed. However, reversals were significantly decreased in the frequency format group, with only 40% of participants' responses being inconsistent. Although preference reversals were not eliminated when the gambles were presented as frequencies they were significantly diminished and may not be such a robust example of irrational decision making after all. 相似文献

Using an experimentally based, computer-presented task, this study assessed cognitive inhibition and interference in individuals from the dissociative identity disorder (DID; n=12), generalized anxiety disorder (GAD; n=12) and non-clinical (n=12) populations. Participants were assessed in a neutral and emotionally negative (anxiety provoking) context, manipulated by experimental instructions and word stimuli. The DID sample displayed effective cognitive inhibition in the neutral but not the anxious context. The GAD sample displayed the opposite findings. However, the interaction between group and context failed to reach significance. There was no indication of an attentional bias to non-schema specific negative words in any sample. Results are discussed in terms of the potential benefit of weakened cognitive inhibition during anxious arousal in dissociative individuals. 相似文献

Exposure to panic symptoms (interoceptive exposure) is often included as part of treatment for panic disorder (PD), although little is known about the relative effects of particular symptom induction exercises. This study describes responses of individuals with PD and nonclinical controls to 13 standard symptom induction exercises and 3 control exercises. Generally, individuals with PD responded more strongly to symptom induction exercises than did controls. The exercises producing the most fear included spinning, hyperventilation, breathing through a straw, and using a tongue depressor. This study also reports findings regarding specific symptoms triggered by each exercise, the percentage of participants reporting fear during each exercise, and predictors of fear. 相似文献

Understanding knowledge effects on attitude-behavior consistency: the role of relevance, complexity, and amount of knowledge 总被引:4,自引:0,他引:4
Fabrigar LR Petty RE Smith SM Crites SL 《Journal of personality and social psychology》2006,90(4):556-577
The role of properties of attitude-relevant knowledge in attitude- behavior consistency was explored in 3 experiments. In Experiment 1, attitudes based on behaviorally relevant knowledge predicted behavior better than attitudes based on low-relevance knowledge, especially when people had time to deliberate. Relevance, complexity, and amount of knowledge were investigated in Experiment 2. It was found that complexity increased attitude- behavior consistency when knowledge was of low-behavioral relevance. Under high-behavioral relevance, attitudes predicted behavior well regardless of complexity. Amount of knowledge had no effect on attitude- behavior consistency. In Experiment 3, the findings of Experiment 2 were replicated, and the complexity effect was extended to behaviors of ambiguous relevance. Together, these experiments support an attitude inference perspective, which holds that under high deliberation conditions, people consider the behavioral relevance and dimensional complexity of knowledge underlying their attitudes before deciding to act on them. 相似文献

Animals readily acquire positive odor-taste hedonic associations, but evidence for this in humans remains weak and was explored further. Retronasal pairing of odors with sucrose or salty stimuli (Experiment 1) increased the rated sweetness of sucrose-paired odors without altering liking, although changes in odor pleasantness correlated with sucrose liking. Experience of odors with sucrose or quinine by sweet likers (Experiment 2) found increased pleasantness and sweetness for sucrose-paired odors, whereas quinine-paired odors became less liked and more bitter. Odor-sucrose pairings in sweet likers and dislikers (Experiment 3) found increased sweetness in both groups but increased odor liking only in likers. These data suggest that evaluative and sensory learning are dissociable and that evaluative changes are sensitive to individual differences in sweet liking. 相似文献

The self-regulatory strength model maintains that all acts of self-regulation, self-control, and choice result in a state of fatigue called ego-depletion. Self-determination theory differentiates between autonomous regulation and controlled regulation. Because making decisions represents one instance of self-regulation, the authors also differentiate between autonomous choice and controlled choice. Three experiments support the hypothesis that whereas conditions representing controlled choice would be egodepleting, conditions that represented autonomous choice would not. In Experiment 3, the authors found significant mediation by perceived self-determination of the relation between the choice condition (autonomous vs. controlled) and ego-depletion as measured by performance. 相似文献
