Using multiple regression analysis and Pearson’s R, the current exploratory study of 89 African American male adolescents (M = 12.5 years old) examined relationships among REI (i.e., 20 as a socialization product of identity formation processes), prosocial behaviors (i.e., represented as supportive behavioral orientation in response to stress), and aggression (i.e., a reactive coping strategy). Significant relationships among racial public regard, age, and verbal aggression emerged. Older adolescents believed that other people have lower regard for their race, and this predicted an increase in verbal aggression. These findings demonstrate the importance of understanding contextual factors when examining outcomes. 相似文献

National differences in subjective well-being (SWB) have been attributed to socioeconomic, climatic, and genetic factors. We focus on one particular facet of SWB—happiness or positive affect—measured by the nationally representative World Values Survey (WVS). We find that national percentages of very happy people across the three latest WVS waves (2000–2004, 2005–2009, 2010–2014) are consistently and highly correlated with national prevalence of the rs324420 A allele in the FAAH gene, involved in the hydrolysis of anandamide, a substance that reportedly enhances sensory pleasure and helps reduce pain. Climatic differences are also significantly associated with national differences in happiness, whereas economic wealth, recent economic growth, rule of law, pathogen prevalence, and the distribution of short versus long alleles in the serotonin transporter gene SLC6A4 are not significant predictors of national happiness. 相似文献

Fraiberg and her colleagues (1975) introduced the metaphor “ghosts in the nursery” to describe the ways in which parents, by reenacting with their small children scenes from the parents' own unremembered early relational experiences of helplessness and fear, transmit child maltreatment from one generation to the next. In this article we propose that angels in the nursery—care‐receiving experiences characterized by intense shared affect between parent and child in which the child feels nearly perfectly understood, accepted, and loved—provide the child with a core sense of security and self‐worth that can be drawn upon when the child becomes a parent to interrupt the cycle of maltreatment. We argue that uncovering angels as growth‐promoting forces in the lives of traumatized parents is as vital to the work of psychotherapy as is the interpretation and exorcizing of ghosts. Using clinical case material, we demonstrate the ways in which early benevolent experiences with caregivers can protect against even overwhelming trauma, and examine the reemergence of these benevolent figures in consciousness as an instrument of therapeutic change. Finally, we examine implications of the concept of “angels in the nursery” for research and clinical intervention. 相似文献

The conventional wisdom among many sociologists is (1) that it is their prerogative to define, document, and explain the inequalities that exist in society and (2) that there are two general theoretical perspectives useful for studying inequality: functionalism and conflict theory. Some scholars have recently challenged the latter portion of this view by advocating the development of more interpretive, interactionist approaches. However, these scholars' agendas often tend to perpetuate the first half of the conventional wisdom. While interactionists (and other constructionist scholars) can choose to study inequality in any number of ways, I argue that the most distinctive contribution they can make is to focus on the meanings that inequalities have for people in everyday life, as well as how those meanings are achieved. 相似文献

Harvey's cognitive model of insomnia (2002a) proposes that sleep-related safety behaviors play a central role in the maintenance of insomnia because such maladaptive coping strategies are thought to reinforce threat-based appraisals of the likelihood and consequences of poor sleep. Research to date has assessed the frequency of safety behavior use in those with insomnia only; however, in addition to the frequency of occurrence, the function of safety behaviors (i.e., a belief that they will prevent a feared outcome from occurring), may be an important consideration. The purpose of this study was to examine sleep-related safety behaviors based on an expanded theoretical understanding of such behaviors across psychological disorders; that is, by examining both their frequency and perceived utility. Undergraduate students (N = 376) completed an online survey about their sleep, mood, and use of sleep-related safety behaviors. Insomnia severity was associated with a greater perceived need to use safety behaviors (i.e., utility) but not with frequency of safety behavior use. Higher perceived utility of safety behaviors was also associated with unhelpful beliefs about sleep, fear and avoidance of fatigue, and both general and sleep-specific helplessness. These results suggest that these behaviors and the associated underlying maladaptive beliefs may be important targets in cognitive behavioral therapy for insomnia. The current study extends the existing literature and refines the concept of safety behaviors in insomnia to include both the function and frequency of these behaviors. 相似文献

Drawing from an interactionist approach and feedback research, we examine the role of developmental feedback and proactive personality on newcomer task performance and helping behavior. Data were collected from 2 high-tech joint-ventures within the information technology and manufacturing industries located in Shanghai, China. Results based on 151 newcomer-manager dyads showed that supervisor developmental feedback (SDF) positively related to newcomer helping behavior and that SDF and coworker developmental feedback interactively predicted newcomer task performance. We also found differential moderating effects of proactive personality: SDF more strongly related to helping behavior when proactive personality was lower; conversely, coworker developmental feedback more strongly related to helping behavior when proactive personality was higher. 相似文献

The present work investigated the effects of caffeine (0 mg, 100 mg, 200 mg, 400 mg) on a flanker task designed to test Posner’s three visual attention network functions: alerting, orienting, and executive control [Posner, M. I. (2004). Cognitive neuroscience of attention. New York, NY: Guilford Press]. In a placebo-controlled, double-blind study using a repeated-measures design, we found that the effects of caffeine on visual attention vary as a function of dose and the attention network under examination. Caffeine improved alerting and executive control function in a dose–response manner, asymptoting at 200 mg; this effect is congruent with caffeine’s adenosine-mediated effects on dopamine-rich areas of brain, and the involvement of these areas in alerting and the executive control of visual attention. Higher doses of caffeine also led to a marginally less efficient allocation of visual attention towards cued regions during task performance (i.e., orienting). Taken together, results of this study demonstrate that caffeine has differential effects on visual attention networks as a function of dose, and such effects have implications for hypothesized interactions of caffeine, adenosine and dopamine in brain areas mediating visual attention. 相似文献

Recent work suggests that a dose of 200–400 mg caffeine can enhance both vigilance and the executive control of visual attention in individuals with low caffeine consumption profiles. The present study seeks to determine whether individuals with relatively high caffeine consumption profiles would show similar advantages. To this end, we examined the effects of four caffeine doses (0 mg, 100 mg, 200 mg, 400 mg) on low- and high-level visual attention in individuals with high consumption profiles (n = 36), in a double-blind study using a repeated measures design. Results from the Attention Network Test indicated that caffeine enhanced both vigilance and the executive control of visual attention, but only at the highest administered dose (400 mg). We demonstrate that in habitual consumers high doses of caffeine can produce beneficial changes in visual attention. These results carry implications for the theorized interactions between caffeine, adenosine and dopamine in brain regions mediating visual attention. 相似文献
