We previously reported that college students who indicated engaging in frequent dream-enacting behaviors also scored high on a new measure of mirror behaviors, which is the propensity to imitate another person’s emotions or actions. Since dream-enacting behaviors are frequently the culmination of nightmares, one explanation for the observed relationship is that individuals who frequently display mirror behaviors are also prone to nightmares. We used the Mirror Behavior Questionnaire (MBQ) and self-reported frequencies of nightmares to assess this possibility.A sample of 480 students, consisting of 188 males (19.2 ± 1.73 years) and 292 females (19.0 ± 1.55 years) enrolled in a first-year university psychology course, participated for course credit. They completed a battery of questionnaires that included the 16-item MBQ, plus an item about nightmare frequency (NMF) in the past 30 days. NMF scores were split to create low, medium, and high NMF groups.MBQ total scores were significantly higher for female than for male subjects, but an interaction revealed that this was true only for Hi-NMF subjects. MBQ Factor 4, Motor Skill Imitation, paralleled this global interaction for females, whereas MBQ Factor 3, Sleepiness/Anger Contagion, was elevated only for Hi-NMF males. Item analyses indicated that Hi- and Med-NMF females scored higher than Lo-NMF females on the 3 items of Factor 4 that reflect voluntary imitation (imitating famous/cartoon voices, being a physically active spectator, and learning new skills by observing), as well as on 2 other items that reflect involuntary imitation (contagious yawning and self-rated empathy). Although Hi- and Lo-NMF males differed most clearly on the sleepiness item of Factor 3, all 3 items on this factor (including anger contagion and contagious yawning) are plausibly associated with perception of and response to social threat.Results provide evidence that among females nightmares are associated with voluntary and involuntary mirror behaviors during wakefulness, while among males nightmares are associated with threat-related mirror behaviors during wakefulness. They thus support the possibility that the association between mirror behaviors and dream-enacting behaviors is due to a common mirror neuron mechanism that underlies mirror behaviors and nightmares and that involves motor, rather than emotional, resonance. These results have implications for understanding the comorbidity of nightmares and other pathological symptoms such as imitative suicidal behaviors, the influence of observational learning on dissociative symptomatology, and the predominance of threat and aggression in the dream enacting behaviors of REM sleep behavior disorder. 相似文献

We examine the theoretical basis for the evolutionary narrative common to the target papers by Saad (this issue) and by Griskevicius and Kenrick (this issue) and identify areas of controversy that have sparked debate about evolutionary psychology [EP] among biologists and behavioral ecologists. The two main areas of disagreement are over (1) the role of genetic adaptations resulting from natural selection in ancient times compared to other forces leading to current behavior; and (2) the likelihood that evolution resulted in a set of highly specialized mental modules or information-processing circuits thought to be instrumental in determining present-day behavior. We review the EP research discussed by the authors of the target papers as a means of evaluating the evidence in support of the theory and of suggesting future directions of research. 相似文献

An acute leukemia diagnosis can be an extremely stressful experience for most patients. Posttraumatic growth (PTG) is positive psychological change experienced following a struggle with highly challenging life circumstances. The current study is the first longitudinal investigation of predictors of PTG and distress in adult acute leukemia patients undergoing induction chemotherapy. Findings suggest that these patients report PTG, and levels of PTG appear to increase over the weeks following leukemia diagnosis and induction chemotherapy. Variables associated with higher total PTG scores over time included greater number of days from baseline, younger age, and greater challenge to core beliefs. Variables associated with higher distress included greater number of days from baseline, greater perceived cancer threat, higher symptom severity, and lower spiritual well-being. Results underscore the critical role that examination of one’s core beliefs may play in the development of PTG over time. 相似文献

Professionals, celebrities, and media frequently suggest to parents the possible treatment options for their children with autism. Some treatment recommendations advocate for scientifically supported treatments whereas others suggest novel, untested interventions, or potentially ineffective or harmful treatments. The current study examined the print media's coverage of applied behavior analysis (ABA) and non‐scientifically supported autism treatments. Over the last 10 years, print media have increasingly published articles referring to autism treatments with little scientific support and a decreased coverage of ABA. Print media's positive statements about non‐scientifically supported treatments also increased over the last decade, whereas positive statements about ABA decreased. ABA received two times as many positive comments as negative; however, non‐scientifically supported treatments as a group received four times as many positive comments as negative. These results could contribute to parents' decisions to implement treatments for their children with autism. To contribute to future positive perception of ABA, we provided suggestions for the dissemination of information to increase positive reporting of ABA in print media.

Links between gun enthusiasm, hypermasculinity, manhood honor maintenance, trait antagonism, and lifetime aggression were examined in this national sample of American men (N = 861). Regression analysis identified honor ideology for manhood and emotion devaluation as the factors that accounted best for gun enthusiasm. Large effect sizes (d > .70 in more than half of the contrasts) were found between cohorts harboring extreme positive versus negative gun attitudes. Gun owners (26.7% of sample) also showed elevations in most of these same trait dimensions, but not lifetime aggression. Gun owners and enthusiasts did not show evidence of childhood maltreatment or current emotional distress. Gun enthusiasts instead seemed to convey a sense of self-assurance and preparedness to respond aggressively to perceived affronts, particularly as they pertained to maintenance of their masculine ideals. 相似文献

Changes to a scene that occur during an eye movement, image flicker, or movie cut are difficult to detect. One way to measure change detection performance is with the flicker paradigm, where changes between two images are introduced during a brief blank screen, which causes the images to “flicker”. Ro, Russell, and Lavie (2001) presented flickering displays consisting of one face and five different common objects. They found that changes to faces were detected both more rapidly and more accurately than changes to objects and suggested that faces capture attention due to their biological significance. In the present studies, we found that changes to objects were more readily detected than changes to faces when displays consisted of an object among a number of faces. That is, a change detection advantage was observed for the “odd-one-out” in the array, regardless of its significance. Therefore, faces may not have a special status for change detection. 相似文献

Much is known about the attractiveness of physical attributes, such as symmetry and averageness. Here we examine the effect of a social cue, eye-gaze direction, on facial attractiveness. Given that direct gaze signals social engagement, we predicted that faces showing direct gaze would be preferred to faces showing averted gaze. Thirty-two males completed two tasks designed to assess preferences for female faces displaying a neutral expression. Participants were more likely to select the face with direct gaze, when choosing the more attractive face from direct- and averted-gaze versions of the same face. This direct-gaze preference was stronger for high-attractive than low-attractive face sets, but was present for both. Attractiveness ratings were also higher for faces with direct than averted gaze. Interestingly, stimulus inversion weakened the preference for inverted faces, which suggests the preference does not simply reflect a bilateral symmetry bias. 相似文献

AbstractUsing a nationally representative sample (N?=?507) from Singapore, this study examined whether personality, financial satisfaction, and autonomy were important to subjective well-being (SWB), and how the importance of these predictors varied across different SWB facets—life satisfaction, happiness, positive feelings, and negative feelings. The findings indicated that neuroticism, financial satisfaction, and autonomy, were important predictors of happiness. Personality was most important for affective well-being (i.e., positive and negative feelings), whereas financial satisfaction was most important for life satisfaction. Specifically, neuroticism accounted for substantial variance in positive and negative feelings, and was the strongest correlate among the Big Five traits. In contrast, financial satisfaction explained most of the variance in life satisfaction. This highlights that the importance of well-being predictors depended on the facet of well-being examined. The findings suggest that residents in an affluent nation like Singapore do not emphasize only postmaterialist values (e.g., autonomy) and disregard materialist concerns (e.g., financial satisfaction). Though certain SWB facets (positive and negative affect) are largely influenced by dispositional factors, other facets (life satisfaction and happiness) are closely related to factors (e.g., financial satisfaction, autonomy) that may be affected by social policies. Policymakers can thus target those aspects to enhance people’s SWB. 相似文献

James Bogen misinterprets what Kierkegaard (or more accurately, Johannes de Silentio) meant by the ethical in Fear and Trembling (see Inquiry, 5 [1962], pp. 305–17). Kierkegaard did not intend to depict morality as a system of duties where moral duties derive from the particular position(s) one holds in society. Kierkegaard thought that moral duties were based on universal principles that were divine commands. Although Kierkegaard thought that it was necessary for an action to be moral that it be done in accord with such universal principles, he did not think that this was sufficient. In order to be a moral action, the action must be done not only in accord with certain universal principles but in a certain way. Kierkegaard notes the appropriate way by saying the agent must reveal himself in his action. Thus revelation by the agent and acting in accordance with certain principles are jointly sufficient and singly necessary conditions for an action to be moral. 相似文献

We conducted a meta‐analysis to determine whether the within‐person self‐efficacy/performance relationship is positive, negative, or null and to compare the strength of the self‐efficacy/performance and past performance/self‐efficacy within‐person relationships. The self‐efficacy/performance within‐person corrected correlation was .23 but was weak and nonsignificant (ρ = .06) when controlling for the linear trajectory, revealing that the main effect was spurious. The past performance/self‐efficacy within‐person corrected correlation was .40 and remained positive and significant (ρ = .30) when controlling for the linear trajectory. The moderator results revealed that at the within‐person level of analysis: (a) self‐efficacy had at best a moderate, positive effect on performance and a null effect under other moderating conditions (ρ ranged from –.02 to .33); (b) the main effect of past performance on self‐efficacy was stronger than the effect of self‐efficacy on performance, even in the moderating conditions that produced the strongest self‐efficacy/performance relationship; (c) the effect of past performance on self‐efficacy ranged from moderate to strong across moderating conditions and was statistically significant across performance tasks, contextual factors, and methodological moderators (ρ ranged from .18 to .52). Overall, this suggests that self‐efficacy is primarily a product of past performance rather than the driving force affecting future performance. 相似文献
