Religion plays a prominent role in Latino culture and could be influential during difficult life transitions, such as those experienced during the immigration process. This study examines relations between religious coping, acculturative stress, and alcohol use in a sample of 415 recent Latino immigrants. Higher levels of acculturative stress were associated more positive and negative religious coping. Positive religious coping was related to lower alcohol use. Negative religious coping moderated the relationship between acculturative stress and alcohol use. Participants who used more negative religious coping had higher rates of alcohol use when experiencing high levels acculturative stress. Implications for culturally tailored prevention/interventions are discussed.  相似文献

African Americans are disproportionately affected by the HIV epidemic inclusive of men who have sex with men, heterosexual men, and women. As part of a community‐based participatory research study we assessed HIV testing experience among sexually active 18–30 year old Black men and women in Durham, NC. Of 508 participants, 173 (74 %) men and 236 (86 %; p = 0.0008) women reported ever being tested. Barriers to testing (e.g., perceived risk and stigma) were the same for men and women, but men fell behind mainly because a primary facilitator of testing—routine screening in clinical settings—was more effective at reaching women. Structural and behavioral risk factors associated with HIV infection were prevalent but did not predict HIV testing experience. Reduced access to health care services for low income Black young adults may exacerbate HIV testing barriers that already exist for men and undermine previous success rates in reaching women.  相似文献

Collective punishment (CP) is deemed unfair because it sanctions group members who are not responsible for the wrongdoing. However, CP may be driven by utilitarian motives, aiming to deter other group members from committing offenses. This research investigated whether individuals’ inclination to support CP for utilitarian reasons is influenced by their belief in the malleability of groups (their belief that groups can change; a growth mindset). In Studies 1 and 2, we assessed utilitarian motives and manipulated participants’ perception of group malleability. In Study 3 , we assessed perceived group malleability and manipulated motives for justice (utilitarianism vs. retribution). Across these studies, the dependent variable was participants’ support for CP. Results consistently showed that utilitarian (more than retributive) motives increased support for CP, specifically among participants who believed in the growth mindset of groups. We discuss the relevance of these findings for social justice and growth mindset literature.  相似文献

In 3 studies, the authors examined the contribution of leaders' attachment styles to their leadership motives and beliefs and to followers' outcomes. In Study 1, participants completed measures of attachment orientation, leadership motives, self-representations, and leadership style. Studies 2 and 3 were conducted within Israeli military units either during a leadership workshop or during intensive combat training. Israeli military officers and their soldiers (followers) reported on their attachment styles, and the soldiers reported on the officers' leadership qualities and on the soldiers' own performance and mental health. Leaders' attachment anxiety was associated with more self-serving leadership motives and with poorer leadership qualities in task-oriented situations. Leaders' attachment anxiety also predicted followers' poorer instrumental functioning. Leaders' attachment-related avoidance was negatively associated with prosocial motives to lead, with the failure to act as a security provider, and with followers' poorer socioemotional functioning and poorer long-range mental health. Results are discussed with respect to the value of attachment theory for the study of leadership.  相似文献

Three levels of working memory load of a visual search (Memory and Search) task were tested in a 72-hour sleep deprivation paradigm. General performance and accuracy decrease over time with monotonic and rhythmic components. The signal detection discriminability index, d', decreases monotonically with rhythmic variations. The index of response bias, β, shows no monotonic trend, but significant circadian rhythmicity. The extent of the monotonic and rhythmic changes in accuracy and in d' is directly related to the level of working memory load. The amplitude of the circadian component of accuracy and d' is enhanced for the higher levels of working memory load. The implication of potentiated circadian rhythmicity as a function of cumulative sleep loss is discussed.  相似文献

In the present research the interaction between the endogenous ligand for the cannabinoid CB1 receptor anandamide (arachidonylethanolamide) and morphine in memory consolidation was investigated. Four sets of experiments were carried out with CD1 mice tested in a one-trial inhibitory avoidance task. The drugs were administered intraperitoneally after training of the animals in the apparatus. In the first set of experiments morphine (0.3 or 0.5, but not 0.15mg/kg) or anandamide (3 or 6 but not 1.5mg/kg) dose-dependently impaired memory consolidation. In the second set of experiments the administration of an otherwise ineffective dose of anandamide (1.5mg/kg) enhanced the memory impairment exerted by morphine (0.3 and 0.5mg/kg) when the drugs were injected immediately after training. In the third set of experiments the combined treatments of anandamide (1.5mg/kg) and morphine (0.5mg/kg) 2h after training were ineffective showing that the effects observed on performance following immediate posttraining administration of anandamide and morphine combinations were reflecting direct influences on memory consolidation. In the fourth set of experiments otherwise ineffective doses of the D1 DA receptor agonist SKF 38393 or the D2 DA receptor agonist LY 171555 antagonized the memory impairment produced by anandamide and morphine in combination, suggesting a possible involvement of dopaminergic mechanisms.  相似文献

Abstract

Four experiments assessed similarities and differences in learned helplessness and depression-related deficits in cognitive performance and self-focused cognitions. Subjects answered the Beck Depression Inventory (Beck, Ward, Mendelson, Mock, & Erbaugh, 1961), were exposed to no-feedback or failure in unsolvable problems, and their response time in a digit comparison task (with or without a memory component, with different number of digits, and different number of mental transformations) and self-focused cognitions were assessed. Learned helplessness and depression deficits were found in a memory task, and the deficits increased with the number of digits. Depression deficits also increased with the number of transformations, and were also found in the no-memory/two transformation condition. Finally, task-related worries were related to learned helplessness deficits, and task-irrelevant thoughts were related to depression deficits. Findings were discussed in terms of the cognitive specificity of learned helplessness and depression deficits.  相似文献

This study examined the contribution of illness severity and attachment style to marital satisfaction among mothers of infants with Congenital Heart Disease (CHD) as well as the mediating role of cognitive appraisal and ways of coping with motherhood tasks. Eighty-five mothers of newborns with CHD rated their attachment style 2 weeks after the infant's CHD diagnosis and two physicians rated the severity of the disease. One year later, mothers completed self-reports scales tapping marital satisfaction, appraisal of motherhood tasks, and ways of coping with these tasks. The severity of infant's disease and mothers’ attachment anxiety and attachment avoidance were related to less marital satisfaction. Moreover, whereas illness severity and attachment anxiety had direct effects on marital satisfaction, the negative effects of attachment avoidance were mediated by the appraisal of motherhood in threatening terms and the reliance on emotion-focused coping. The interconnections between attachment style, the process of coping with the stress of a chronic illness, and marital satisfaction were discussed.  相似文献
