Using data from the Health and Retirement Study, I examine the relationship between adult mortality and religious affiliation. I test whether mortality differences associated with religious affiliation can be attributed to differences in socioeconomic status (years of education and household wealth), attendance at religious services, or health behaviors, particularly cigarette and alcohol consumption. A baseline report of attendance at religious services is used to avoid confounding effects of deteriorating health. Socioeconomic status explains some but not all of the mortality difference. While Catholics, Evangelical Protestants, and Black Protestants benefit from favorable attendance patterns, attendance (or lack of) at services explains much of the higher mortality of those with no religious preference. Health behaviors do not mediate the relationship between mortality and religion, except among Evangelical Protestants. Not only does religion matter, but studies examining the effect of "religiosity" need to consider differences by religious affiliation.  相似文献

We examined associations between children’s peer relationships and (a) their parents’ social competence as well as (b) their parents’ behaviors during the children’s peer interactions. Participants were families of 124 children ages 6–10 (68% male), 62 with ADHD and 62 age- and sex-matched comparison youth. Children’s peer relationships were assessed via parent and teacher report, and sociometric nominations in a lab-based playgroup. Parental characteristics were assessed via parent self-report and observations of behavior during their child’s playgroup. After statistical control of relevant covariates, parents of children with ADHD reported poorer social skills of their own, arranged fewer playdates for their children, and displayed more criticism during their child’s peer interaction than did parents of comparison youth. Parents’ socialization with other parents and facilitation of the child’s peer interactions predicted their children having good peer relationships as reported by teachers and peers, whereas parental corrective feedback to the child and praise predicted poor peer relationships. Parents’ ratings of their child’s social skills were positively associated with ratings of their own social skills, but negatively associated with criticism and facilitation of the child’s peer interactions. Relationships between parental behaviors and peer relationships were stronger for youth with ADHD than for comparison youth. The relevance of findings to interventions is discussed.  相似文献

Previous accounts of the memory distortion known as the change-of-standard effect hypothesize that participants form a relative impression of a target at encoding and later use that impression with the average of all items to recall the target (Higgins & Lurie, 1983). In three experiments, we investigated the standard and the integration of the standard with the relative impression. Experiments 1 and 2 show that participants’ subjective average at recall is distorted toward recent stimuli: It is computed when required and is therefore affected by the items’ accessibility at that time. Furthermore, the impression’s influence on recall is relatively small when the context changes between encoding and decoding. Experiment 3 shows that this change in the impression’s influence occurs only when the participant integrates information across sessions, suggesting that such tasks make participants aware of the changed context and cause them to adjust the use of their impression in recalling the target.  相似文献

This study tested the dual‐process motivational (DPM) model, which posits that right‐wing authoritarianism (RWA) and social dominance orientation (SDO) differentially predict attitudes toward socially threatening or subordinate groups, respectively. Participants read articles on same‐sex relationships and affirmative action and evaluated the article content and the biases of the article authors. The article conclusions (i.e., pro‐ or anti‐same‐sex relationships and affirmative action) were varied between subjects. As expected, only RWA predicted evaluations of the same‐sex relationships articles and authors, whereas only SDO predicted evaluations of the affirmative action articles and authors. These results extend applications of the dual‐process model by demonstrating that RWA and SDO differentially predict evaluations of political information that pertains to socially threatening or subordinate groups, respectively.  相似文献

Rotations are fundamental to motor control, not only for orienting to stimuli but also in the joint articulations that underlie translational movements. Studying three-dimensional (3-D) rotations of the simplest joint system, the eye, has provided general insights into the neural control of movement. First, in selecting one 3-D eye orientation for each two-dimensional (2-D) gaze direction, the oculomotor system generates a behavior called Listing's law that constrains eye position to a 2-D plane, Listing's plane. This selection is made internally by an inverse kinematic transformation called the Listing's law operator. Second, the oculomotor system incorporates the inherent multiplicative relationship between rotational velocity and position to generate the 3-D movement and position commands required by Listing's law. Finally, the coordinate systems for these commands appear to align with Listing's plane rather than with anatomic structures. Recent investigations have revealed similar behavioral constraints in the orientations of the head and arm, suggesting that the neural mechanisms for Listing's law may have analogues in many motor systems.  相似文献

Although numerous studies have attempted to understand the causes of various forms of police misconduct, there is still no clear theoretical explanation of police misbehavior. Akers’ social learning theory posits that peer associations, attitudes, reinforcement, and modeling are predictors of delinquency and crime in general. With this article, we seek to determine if the theory can account for police deviance. Data from a random sample of Philadelphia police officers are used to examine how officer attitudes and perceptions of peer behavior are related to citizen complaints of police misconduct. Findings suggest that social learning theory provides a useful explanation of police misconduct.  相似文献

The trunk muscle transversus abdominis (TrA) is thought to be controlled independently of the global trunk muscles. Methodological issues in the 1990s research such as unilateral electromyography and a limited range of arm movements justify a re-examination of this theory. The hypothesis tested is that TrA bilateral co-contraction is a typical muscle synergy during arm movement. The activity of 6 pairs of trunk and lower limb muscles was recorded using bilateral electromyography during anticipatory postural adjustments (APAs) associated with the arm movements. The integrated APA electromyographical signals were analyzed for muscle synergy using Principle Component Analysis. TrA does not typically bilaterally co-contract during arm movements (1 out of 6 participants did). APA muscle activity of all muscles during asymmetrical arm movements typically reflected a direction specific diagonal pattern incorporating a twisting motion to transfer energy from the ground up. This finding is not consistent with the hypothesis that TrA plays a unique role providing bilateral, feedforward, multidirectional stiffening of the spine. This has significant implications to the theories underlying the role of TrA in back pain and in the training of isolated bilateral co-contraction of TrA in the prophylaxis of back pain.  相似文献

Theoretical models suggest a positive relationship between sleep quality and individuals' ability to regulate emotion. However, few studies have empirically tested this hypothesised link using standardised laboratory measures of emotion-regulation ability. The present research examined the relationship between sleep quality and the ability to implement a type of emotion regulation that has particularly important implications for psychological health: cognitive reappraisal (cognitively reframing an emotional event so as to dampen its impact). To do so, 156 participants (86 male) reported on their past week's sleep quality. Their ability to implement cognitive reappraisal (CRA) was then measured with a standardised laboratory challenge. Participants with poorer self-reported sleep quality exhibited lower CRA, even after controlling for fourteen potential key confounds (e.g., age, negative affect, mood disorder symptoms, stress). This finding is consistent with the idea that poorer sleep quality impairs individuals' ability to engage in the crucial task of regulating negative emotions.  相似文献

An active duty Air Force ground combat unit (n = 189) completed surveys about trauma and combat exposure, mood symptoms, and meaning in life. Two dimensions of deployment-related traumas were assessed: combat (e.g., firing weapons, being fired upon) and aftermath (e.g., seeing dead bodies, injury). Results of regression analyses indicated that Airmen who experienced more intense combat reported less presence of meaning in life, although the significant interaction with gender suggested declines in meaning in life were especially pronounced among males with higher combat intensity. In contrast, more intense aftermath exposure was associated with slightly stronger meaning in life, with no differences by gender. Intensity of combat exposure might differentially affect perceived meaning in life for male versus female combatants.  相似文献

We examine the association between neighborhood socio-economic disadvantage and perceived stress during middle and late adolescence among African American youth (N = 665; 51 % female; M = 15.9 years at baseline). In addition, we explored the ways through which neighborhood stressors interacted with an individual’s intra- and interpersonal resources (e.g., coping, social support and substance use), to affect their perceived stress trajectories during adolescence. First, we tested a neighborhood stressors model and found that youth who lived in neighborhoods with greater socioeconomic disadvantage had higher baseline stress and a steeper increase in stress over time. When we included individual-level risk and promotive factors in the model, however, the effect of neighborhood disadvantage on perceived stress was no longer significant, and the stress trajectory was explained by adolescent substance use, social support and perceptions of the neighborhood. Our results support theories of stress and coping, and the importance of proximal intra- and interpersonal factors in either amplifying or mitigating perceptions of stress. We discuss implications of the neighborhood context and how our findings may inform future prevention and intervention related to adolescent stress and development.  相似文献
