The purpose of the present study was to examine whether coping mechanisms predict physical health, after controlling for posttraumatic stress disorder (PTSD) symptom clusters in a non-clinical sample of adults. Data were collected from 483 adults through an online survey. Most of the participants (66.7%) reported lifetime exposure to at least one traumatic event. The final sample of this study included 319 trauma-exposed individuals. Results indicated that PTSD symptoms on the avoidance and hyperarousal clusters had significant positive relationships with self-reported physical health symptoms. After controlling for gender and PTSD, denial, behavioral disengagement, and self-blame significantly and positively predicted physical health symptoms. 相似文献

How does one find objects in scenes? For decades, visual search models have been built on experiments in which observers search for targets, presented among distractor items, isolated and randomly arranged on blank backgrounds. Are these models relevant to search in continuous scenes? This article argues that the mechanisms that govern artificial, laboratory search tasks do play a role in visual search in scenes. However, scene-based information is used to guide search in ways that had no place in earlier models. Search in scenes might be best explained by a dual-path model: a 'selective' path in which candidate objects must be individually selected for recognition and a 'nonselective' path in which information can be extracted from global and/or statistical information. 相似文献

Although authorship policies exist, researchers understand little about their impact on perceptions of authorship scenarios. Graduate students (N=277) at a large university read 1 of 3 vignettes about a graduate student-faculty collaboration. One half of the surveys included the American Psychological Association's statement on authorship. Participants rated (a) the ethics of the professor as first author and (b) the likelihood of a dissatisfied student reporting the authorship result, as well as the effectiveness and negative consequences of reporting. Work arrangements on the project had a consistent main effect. Also, an authorship policy impacted women's ratings of first authorship when the student contributed the idea for a project. For men, a policy impacted only ratings of the likelihood of reporting when a professor was first author on a student's dissertation. Apart from sex, no other demographic variables on participants were predictive. Discussion focuses on the policy's potential for making only some specific issues salient. 相似文献

The present study is an examination of the influence of cultural background on the ways in which the aged cope with loneliness.
Thirty-six participants from Canada and 105 from Portugal (60-83 years old) answered an 86-item questionnaire which examined
thebeneficial strategies which they used to cope with loneliness. The strategies which were examined included Acceptance and Reflection,
Self-Development and Understanding, Social Support Network, Distancing and Denial, Religion and Faith, and Increased Activity.
Results indicated that the elderly of the two cultures differ on three subscales. Gender differences between and within cultures
were also examined. 相似文献

Three studies examined the relative valence and strength of implicit attitudes toward Arab-Muslims using the Implicit Association Test (IAT) while exploring the moderation of such implicit effects. Studies have suggested that repeated exposure to information associating members of a social group (e.g., Arab-Muslims) with evaluative attributes (e.g., terrorism) might create automatic attitudes toward them. Consistent with this notion, the IAT results indicated strong implicit preference for White over Arab-Muslim, whereas the magnitude of such a bias was substantially diminished when assessed by explicit measures (Study 1). It is also interesting to note that participants exhibited implicit preference for Black over Arab-Muslim when measured by the IAT, whereas no difference was found between the 2 groups in stimulus familiarity and in explicit attitudes (Studies 2 and 3). However, such implicit effects were moderated when participants were exposed to positive information about Arab-Muslims (Study 3). Theoretical and practical implications of these findings are further discussed. 相似文献

This study focused on characteristics of the family environment that may mediate the relationship between disaster exposure and the presence of symptoms that met DSM-IV diagnostic criteria for symptom count and duration for an internalizing disorder in children and youth. We also explored how parental history of mental health problems may moderate this mediational model. Approximately 18 months after Hurricane Georges hit Puerto Rico in 1998, participants were randomly selected based on a probability household sample using 1990 US Census block groups. Caregivers and children (N?=?1,886 dyads) were interviewed with the Diagnostic Interview Schedule for Children and other questionnaires in Spanish. Areas of the family environment assessed include parent-child relationship quality, parent-child involvement, parental monitoring, discipline, parents’ relationship quality and parental mental health. SEM models were estimated for parents and children, and by age group. For children (4–10 years old), parenting variables were related to internalizing psychopathology, but did not mediate the exposure-psychopathology relationship. Exposure had a direct relationship to internalizing psychopathology. For youth (11–17 years old), some parenting variables attenuated the relation between exposure and internalizing psychopathology. Family environment factors may play a mediational role in psychopathology post-disaster among youth, compared to an additive role for children. Hurricane exposure had a significant relation to family environment for families without parental history of mental health problems, but no influence for families with a parental history of mental health problems. 相似文献

This article focuses on emergency medical care in black urban populations, suggesting that the classification of a "community" within clinical trial language is problematic. The article references a cultural history of black Americans with pre-hospital emergency medical treatment as relevant to contemporary emergency medicine paradigms. Part I explores a relationship between "autonomy" and "community." The idea of community emerges as a displacement for the ethical principle of autonomy precisely at the moment that institutionalized medicine focuses on diversity. Part II examines a clinical trial for the blood substitute PolyHeme (Northfield Laboratories, Inc., Evanston, IL). It illustrates the ways in which bias in research paradigms and Institutional Review Board decisions attach to the notion and utility of the language of "community." The conclusion's contemporary anecdote makes apparent the vitality of the issues of prehospital emergency medical care and the ways in which decisions and practices fall too easily into a narrative of culturally biased treatment. 相似文献

Studies have suggested attention-free semantic processing of natural scenes in which concurrent tasks leave category detection unimpaired (e.g., F. Li, R. VanRullen, C. Koch, & P. Perona, 2002). Could this ability reflect detection of disjunctive feature sets rather than high-level binding? Participants detected an animal target in a rapid serial visual presentation (RSVP) sequence and then reported its identity and location. They frequently failed to identify or to localize targets that they had correctly detected, suggesting that detection was based only on partial processing. Detection of targets was considerably worse in sequences that also contained humans, presumably because of shared features. When 2 targets were presented in RSVP, a prolonged attentional blink appeared that was almost eliminated when both targets were detected without being identified. The results suggest rapid feature analysis mediating detection, followed by attention-demanding binding for identification and localization. 相似文献

It is well established that the cerebellum and its associated circuitry are essential for classical conditioning of the eyeblink response and other discrete motor responses (e.g., limb flexion, head turn, etc.) learned with an aversive unconditioned stimulus (US). However, brain mechanisms underlying extinction of these responses are still relatively unclear. Behavioral studies have demonstrated extinction as an active learning process distinct from acquisition. Experimental data in eyeblink conditioning suggest that plastic changes specific to extinction may play an important role in this process. Both cerebellar and hippocampal systems may be involved in extinction of these memories. The nature of this phenomenon and identification of the neural substrates necessary for extinction of originally learned responses is the topic of this review. 相似文献

Prior person perception studies exposednormative expectations about family size such thatvoluntary childfree and single-child women werestigmatized and large-family mothers were glorified. Incontrast, self-reports find no differences in subjectivewell-being among these non-normative and 2 to 3 child,normative women. To explore mostly white,college-educated, employed women's experiences withtheir real-life family size choices, interviews wereconducted with 15 voluntary childfree, 15 one-child, and15 supernormative mothers of 4+ children, and 15normative mothers completed a comparison survey. Quantitative and qualitative analyses revealedpatterns of universal satisfaction, yet stigmatizationacross the three non-normative groups, such as pressurefrom outsiders (including medical professionals) to stay within normative parameters persisted.One-child and supernormative mothers reported thatothers are critical of their child's well-being,intimating selfishness and neglect, respectively. These findings help coalesce the conclusions ofearlier studies. 相似文献
