Rumination partially mediates the associations between perceived ethnic discrimination, emotional distress, and aggression 总被引:1,自引:0,他引:1
Research suggests that perceived ethnic discrimination is associated with poor psychological and physiological health. Rumination, or perseverative thoughts about negative experiences, may constitute a maladaptive coping strategy that mediates the associations between perceived discrimination, emotional distress, and aggression. Our sample consisted of 170 ethnic minority and 134 White American participants. For ethnic minority participants, we found a pattern of correlations consistent with rumination partially mediating a causal link between perceived discrimination and depressive symptoms, hostility, anger, and aggression. In White participants, by contrast, the significant associations between perceived discrimination and these indices of emotional and behavioral distress were not statistically mediated by rumination. We discuss possible theoretical and clinical implications of these results. 相似文献

The goals of the current study were to investigate the stability of temperamental exuberance across infancy and toddlerhood and to examine the associations between exuberance and social-emotional outcomes in early childhood. The sample consisted of 291 4-month-olds followed at 9, 24, and 36 months and again at 5 years of age. Behavioral measures of exuberance were collected at 9, 24, and 36 months. At 36 months, frontal electroencephalogram (EEG) asymmetry was assessed. At 5 years, maternal reports of temperament and behavior problems were collected, as were observational measures of social behavior during an interaction with an unfamiliar peer in the laboratory. Latent profile analysis revealed a high, stable exuberance profile that was associated with greater ratings of 5-year externalizing behavior and surgency, as well as observed disruptive behavior and social competence with unfamiliar peers. These associations were particularly true for children who displayed left frontal EEG asymmetry. Multiple factors supported an approach bias for exuberant temperament but did not differentiate between adaptive and maladaptive social-emotional outcomes at 5 years of age. 相似文献

This study investigated the impact of sorority rush on self-objectification and body image disturbance. First-year undergraduate women either participating (n?=?68) or not participating (n?=?59) in sorority rush at a U.S. Midwestern university completed online surveys at four time points. It was predicted that rush participation would lead to increases in self-objectification, which in turn would lead to increases in body shame and eating disordered behavior and attitudes. Results supported predictions based on objectification theory at a single time point, but not longitudinally. Rush participants evidenced higher levels of self-objectification and eating disordered behavior at all time points. Body mass index predicted dropping out of the rush process and was negatively correlated with satisfaction with the rush process. 相似文献

Neuronal activity regulated pentraxin (Narp) is a secreted protein that regulates α-amino-3-hydroxyl-5-methyl-4-isoxazole-propionate receptors (AMPAR) aggregation and synaptogenesis. Mapping of Narp-positive neurons in brain has revealed it is prominently expressed in several limbic system projection pathways. Consistent with this localization pattern, Narp knockout mice show deficits in using the current value of a reinforcer to guide behavior, a critical function of the limbic system. To help assess whether this behavioral deficit is due to impairment of synaptogenesis during development or in modulating synaptic signaling in the mature brain, we have used a dominant negative Narp viral construct which blocks trafficking of endogenous Narp to axons. Focal injection of this viral construct into the medial prefrontal cortex (mPFC) of adult mice, a region containing Narp-positive projection neurons, blocked reinforcer devaluation. Thus, these results indicate that Narp released from mPFC neurons plays a key role in mediating synaptic changes underlying instrumental reinforcer devaluation. 相似文献

Certain caregiver eating messages – restriction of food intake and pressures to eat – are associated with body dissatisfaction and eating disturbances among young girls. This study explored whether these messages are also associated with body attitudes and eating behaviors of young adult women and men. The Caregiver Eating Messages Scale was developed to measure this construct. Two studies (Ns = 238, 288) indicated that it contained two factors (restrictive/critical messages and pressure to eat messages) and yielded internally consistent, stable, and valid scores. Both factors were positively related to women's BMI, and restrictive/critical messages were positively related to men's BMI. Restrictive/critical messages predicted lower perceived familial body acceptance and intuitive eating and higher perceived familial pressure to be lean and disordered eating. Restrictive/critical messages predicted participants’ body attitudes indirectly via their perceptions of their family's attitude toward their body, with one exception: restrictive/critical messages uniquely predicted men's body appreciation. 相似文献

Two studies of ethnically diverse US college students from northern California examined whether ingroup bias and gender norm violations influence acquaintance rape attributions (Study 1, N?=?118; Study 2, N?=?140). Participants read vignettes depicting acquaintance rape and completed questionnaires. Victims were part of participants’ ingroup or outgroup. Study 1 manipulated the victim’s sexual history (chaste or promiscuous). Study 2 manipulated the victim’s alcohol use (sober or intoxicated). Ingroup victims were perceived more positively than outgroup victims if the victims were promiscuous or intoxicated. More guilt was attributed to rapists of ingroup victims than outgroup victims if the victims were promiscuous or intoxicated. Findings are examined in relation to ingroup bias and gender norm violations. 相似文献

The predictive validity of symptom criteria for different subtypes of ADHD among children who were impaired in at least one
setting in early childhood was examined. Academic achievement was assessed seven times over 8 years in 125 children who met
symptom criteria for ADHD at 4–6 years of age and in 130 demographically-matched non-referred comparison children. When intelligence
and other confounds were controlled, children who met modified criteria for the predominantly inattentive subtype of ADHD
in wave 1 had lower reading, spelling, and mathematics scores over time than both comparison children and children who met
modified criteria for the other subtypes of ADHD. In some analyses, children who met modified criteria for the combined type
had somewhat lower mathematics scores than comparison children. The robust academic deficits relative to intelligence in the
inattentive group in this age range suggest either that inattention results in academic underachievement or that some children
in the inattentive group have learning disabilities that cause secondary symptoms of inattention. Unexpectedly, wave 1 internalizing
(anxiety and depression) symptoms independently predicted deficits in academic achievement controlling ADHD, intelligence,
and other predictors. 相似文献

As part of a longitudinal study, the Cognitive Triad Inventory for Children (CTI-C; N. J. Kaslow, K. D. Stark, B. Printz, R. Livingston, & S. L. Tsai, 1992) as well as other measures of cognitive style and depressive symptoms were administered annually to 3 cohorts of children starting in Grades 2, 4, and 6. Developmentally based analyses revealed 4 things: (a) The factor structure of the CTI-C changed over the course of middle childhood and then stabilized in early adolescence; (b) the CTI-C correlated significantly with measures of depression, self-perceived competence, self-worth, perceived controllability, and perceived contingency, but not with measures of attributional style; (c) 1-year stability correlations increased substantially from Grade 2 to Grade 8; and (d) the CTI-C did not generally predict self-reported depressive symptoms 1 year later. Implications emerge regarding developmental changes in the structure of children's depressive cognitions. 相似文献

Previous research has demonstrated that jurors perceive a female victim who is drunk at the time when she is sexually assaulted as less credible and more deserving of such punishment than a sober victim. In this experiment, we investigated the effect of an alleged acquaintance rape victim’s type of substance use and closeness of relationship with the defendant on the judgments of 152 student mock jurors. Participants read a case summary and answered a series of questions about their impressions of the actors and actions involved in the case. Participants perceived a victim who was sober at the time of the incident as more credible than a victim who was intoxicated due to illegal substance use (alcohol or LSD), and convictions were also most likely when the victim was sober. Women perceived the victim as more credible than men did. Higher victim credibility judgments were associated with less rape myth acceptance (RMA) on the part of participants. 相似文献
