The current study adds to prior research by investigating specific (happiness, sadness, surprise, disgust, anger and fear) and general (corrugator and zygomatic muscle activity) facial reactions to violent and comedy films among individuals with varying levels of callous–unemotional (CU) traits and impulsive aggression (IA). Participants at differential risk of CU traits and IA were selected from a sample of 1225 young adults. In Experiment 1, participants (N?=?82) facial expressions were recorded while they watched violent and comedy films. Video footage of participants' facial expressions was analysed using FaceReader, a facial coding software that classifies facial reactions. Findings suggested that individuals with elevated CU traits showed reduced facial reactions of sadness and disgust to violent films, indicating low empathic concern in response to victims' distress. In contrast, impulsive aggressors produced specifically more angry facial expressions when viewing violent and comedy films. In Experiment 2 (N?=?86), facial reactions were measured by monitoring facial electromyography activity. FaceReader findings were verified by the reduced facial electromyography at the corrugator, but not the zygomatic, muscle in response to violent films shown by individuals high in CU traits. Additional analysis suggested that sympathy to victims explained the association between CU traits and reduced facial reactions to violent films. 相似文献

Recent conceptual work draws meaningful distinctions between experiential and declarative well‐being (Shmotkin, 2005 ), but little has been done to apply such distinctions in organisational psychology. We use this framework to integrate self‐determination theory (Deci & Ryan, 1985 ) and flow theory (Csikszentmihalyi, 1975 ), leading to hypotheses proposing that flow experiences at work (experiential well‐being) lead to declarative well‐being outcomes through their influence on the satisfaction of basic psychological needs for competence and autonomy. Findings from a two‐week experience sampling study of full‐time employees offer support for our hypotheses. This study also shows support for the moderating effect of individual differences in personality on the relationships among flow experiences, need fulfillment, and declarative well‐being. 相似文献

The current research investigated the well-established outgroup homogeneity effect in face memory (worse recognition for outgroup faces than ingroup faces). Because past research has shown that group distinctiveness threat can enhance ingroup homogeneity, of interest in the current research was whether distinctiveness threat affects face recognition. Across two studies, we found that threatening White American participants’ ethnic distinctiveness led to a reduction in same-race face recognition. In other words, distinctiveness threat created ingroup homogeneity in face memory. In both studies, distinctiveness threat led Whites’ same-race recognition to drop to cross-race levels. Implications were discussed in terms of how the structure of intergroup relations may drive intergroup differences in face memory. 相似文献

In everyday life people estimate completion times for projects in the near and distant future. How might the temporal proximity of a project influence prediction? Given that closer events elicit more concrete construals, we proposed that temporal proximity could enhance two kinds of concrete cognitions pertinent to task completion predictions: step-by-step plans and potential obstacles. Although these cognitions have opposite implications for prediction, and thus could cancel each other out, we hypothesized that temporal proximity would have a greater impact on cognitions that were relatively focal. Thus contextual factors that alter the relative focus on plans vs. obstacles should determine whether and how temporal proximity affects prediction. Six studies supported this reasoning. In contexts that elicited a focus on planning, individuals predicted earlier completion times for close than distant projects. In contexts that prompted a focus on obstacles, individuals predicted later completion times for close than distant projects. 相似文献

Social buffering is characterized by attenuation of stress in the presence of others, with supportive individuals providing
superior buffering. We were interested in learning if the implied presence of a supportive entity, God, would reduce acute
stress. Participants were randomly assigned to one of three conditions: prayer, encouraging self-talk, and control. They were
subsequently placed in a stressful situation. Self ratings of stress were lower among the prayer and self-talk conditions
relative to controls. Systolic and diastolic blood pressures only among those who prayed were lower than controls; however,
prayer and self-talk did not differ. Prayer alone did not significantly reduce stress, perhaps because the majority of students
in the prayer condition did not consider reading a prayer to constitute praying. 相似文献

Research suggests that adolescents’ engagement in nonsuicidal self-injurious (NSSI) behaviors may be increasing over time,
yet little is known regarding distal longitudinal factors that may promote engagement in these behaviors. Data from two longitudinal
studies are presented to examine whether NSSI may be associated with peer influence processes. Study 1 included 377 adolescents
from a community-based sample; Study 2 included 140 clinically-referred adolescents recruited from a psychiatric inpatient
facility. In Study 1, adolescents’ NSSI was examined at baseline and one year later. Adolescents’ nominated best friend reported
their own levels of NSSI. In Study 2, adolescents’ NSSI was examined at baseline as well as 9 and 18-months post-baseline.
Adolescents’ perceptions of their friends’ engagement in self-injurious behavior (including suicidality) and depressed mood
also were examined at all three time points. Baseline depressive symptoms were measured in both studies; gender and age were
examined as moderators of peer influence effects. Results from both studies supported longitudinal peer socialization effects
of friends’ self-injurious behavior on adolescents’ own NSSI for girls, but not for boys, even after controlling for depressive
symptoms as a predictor. Study 1 suggested socialization effects mostly for younger youth. Results from Study 2 also suggested
longitudinal socialization effects, as well as peer selection effects; adolescents’ NSSI was associated with increasing perceptions
of their friends’ engagement in depressive/self-injurious thoughts and behavior. Findings contribute to the nascent literature
on longitudinal predictors of NSSI and to work on peer influence. 相似文献

Substantial evidence links perception of others’ bodies and mental representation of the observer’s own body; however, the overwhelming majority of this evidence is unidirectional, showing influence from perception to action. It has been proposed that the influence also runs from action to perception, but to date the evidence is scant. Here we report that ordinary motor actions performed by the subject affect concurrent psychophysical judgments of human-body stimuli. Subjects remained unaware of the connection between the action and the main task. The results show that perception can change as a result of the observer’s ongoing actions. 相似文献

When primed by backward-masked, target-like stimuli, discrete responses (e.g. button presses) to simple visual targets can be slower when prime and target match (compatible) than when they do not (incompatible). The current study investigated the nature of the stimulus–response mapping underlying this negative compatibility effect (NCE). Discrete left–right responses to arrow targets were primed with arrows oriented in one of 16 directions. Responses were either a standard button press or a 10 cm movement on a graphics tablet. Both tasks showed an identical NCE; importantly, reaction times in both tasks decreased smoothly as the angular distance between prime and target increased (i.e. as compatibility decreased), with the largest NCE evident between the extreme cases (prime-target distances of 0° and 180°). Primes exerted an effect on the required response in proportion to the amount of overlap (reflecting population vector coding). The mapping between the priming stimulus and response is continuous, not categorical. 相似文献

Estrogen has been shown to have a strong modulatory influence on several types of cognition in both women and female rodents. Latent inhibition is a task in which pre-exposure to a neutral stimulus, such as a tone, later impedes the association of that stimulus with a particular consequence, such as a shock. Previous work from our lab demonstrates that high levels of estradiol (E2) administered to ovariectomized (OVX) female rats abolishes latent inhibition when compared to female rats with low levels of E2 or male rats. To determine if this E2-induced impairment also occurs with the natural variations of ovarian hormones during the estrous cycle, this behavior was investigated in cycling female rats. In addition, pre-pubertal male and female rats were also tested in this paradigm to determine if the previously described sex differences are activational or organizational in nature. In a latent inhibition paradigm using a tone and a shock, adult rats were conditioned during different points of the estrous cycle. Rats conditioned during proestrus, a period of high E2 levels, exhibited attenuated latent inhibition when compared to rats conditioned during estrus or metestrus, periods associated with low levels of E2. Moreover, this effect is not seen until puberty indicating it is dependent on the surge of hormones at puberty. This study confirms recent findings that high E2 interferes with latent inhibition and is the first to show this is based in the activational actions of hormones. 相似文献
