This study examined demographic and mental health correlates of subjective well-being (i.e., life satisfaction, happiness) using a national sample of older African Americans with psychiatric disorders. We used a subsample of 185 African Americans, 55 and older with at least one of thirteen lifetime psychiatric disorders from The National Survey of American Life: Coping with Stress in the Twenty-first Century. The findings indicated that among this population of older adults who had a lifetime psychiatric disorder, having a lifetime suicidal ideation was associated with life satisfaction but not happiness. Further, having a 12-month anxiety disorder or a lifetime suicidal ideation was not associated with happiness. Having a 12-month mood disorder, however, was negatively associated with an individual’s level of happiness, as well as their life satisfaction. Additionally, there were two significant interactions. Among men, employment was positively associated with life satisfaction, and marriage was associated with higher levels of happiness among men but not women. The overall pattern of findings reflects both similarities and departures from prior research confirming that well-being evaluations are associated with multiple factors.  相似文献

This research examined the impact of affectivity and coping on state anxiety and positive emotions among young adults living in the Washington, DC metro area both during and after the Washington, DC sniper killings. Participants completed questionnaires during three waves of data collection: (1) during the sniper attacks (n=92); (2) within two weeks after the snipers were captured (n=45); and (3) six months later (n=43). Affectivity (measured by neuroticism) was significantly associated with state anxiety and positive emotions during all three time periods. Coping (measured by constructive thinking) predicted state anxiety and positive emotions during the shootings, but was unrelated to either outcome immediately after the attacks, and marginally related to them six months later. Consistent with the Dynamic Model of Affect, state anxiety and positive emotions were more strongly (and negatively) correlated with each other during the killings than they were after the snipers were apprehended. Taken together, these results support transactional models of stress that emphasize the interaction between dispositional and situational influences, and they suggest that affectivity reflects a fundamental set of reactions to one's environment, while coping dispositions result in more stress-specific responses. Additional theoretical and practical implications of these findings are also discussed.  相似文献

Past research has demonstrated that convex regions are increasingly likely to be perceived as figures as the number of alternating convex and concave regions in test displays increases. This region-number effect depends on both a small preexisting preference for convex over concave objects and the presence of scene characteristics (i.e., uniform fill) that allow the integration of the concave regions into a background object/surface. These factors work together to enable the percept of convex objects in front of a background. We investigated whether region-number effects generalize to another property, symmetry, whose effectiveness as a figure property has been debated. Observers reported which regions they perceived as figures in black-and-white displays with alternating symmetric/asymmetric regions. In Experiments 1 and 2, the displays had articulated outer borders that preserved the symmetry/asymmetry of the outermost regions. Region-number effects were not observed, although symmetric regions were perceived as figures more often than chance. We hypothesized that the articulated outer borders prevented fitting a background interpretation to the asymmetric regions. In Experiment 3, we used straight-edge framelike outer borders and observed region-number effects for symmetry equivalent to those observed for convexity. These results (1) show that display-wide information affects figure assignment at a border, (2) extend the evidence indicating that the ability to fit background as well as foreground interpretations is critical in figure assignment, (3) reveal that symmetry and convexity are equally effective figure cues and, (4) demonstrate that symmetry serves as a figural property only when it is close to fixation.  相似文献

Bystander intervention has been increasingly applied to prevent sexual violence on college campuses. Its underlying theory assumes unidirectional relationships between variables, predicting that bystander behaviors (i.e., actions taken to intervene in sexual violence situations) will be influenced by bystander intentions (BI; i.e., likelihood to intervene in the future), which in turn will be affected by bystander efficacy (BE; i.e., confidence to intervene). One question for theory is whether a reciprocal relationship exists between BI and BE. We used structural equation modeling (SEM) with longitudinal data to test unidirectional and reciprocal causal relations between BI and BE. Participants (n = 1390) were students at a northeastern US university. Four models were examined using SEM: (1) a baseline model with autoregressive paths; (2) a model with autoregressive effects and BI predicting future BE; (3) a model with autoregressive effects and BE predicting future BI; and, (4) a fully cross‐lagged model. Results indicated that reciprocal causality was found to occur between BI and BE. In addition, a final model demonstrated indirect effects of a bystander intervention program on bystander behaviors through both BI and BE at different time points. Implications for theory and practice are described, and directions for future research discussed.  相似文献

A review of timc-period research on temperature and aggression led the authors to hypothesize that southern subculture and sociodemographic variables are responsible for geographical differences in I1.S. homicide rates. It was also hypothesized that temperature's correlation with nonhomicidal violencc would be stronger in small than large cities. These hypotheses were tested by obtaining cross-sectional data on I0 temperature indexes, 11 sociodemographic controls, percentage southern horn, and crime rates in more than 300 U.S. cities in 1990. Partial correlation analyses indicated that percentage southern born and sociodernographic variables rather than temperature predicted homicide rates. Moderator variable regression analyses indicated that relationships between temperature and nonhomicidal violence were stronger in small than large cities. The results are interpreted in terms of a social escapeiavoidance model of criminal behavior, which predicts that low as well as high temperatures lead co-offenders to avoid social contact.  相似文献

Treatments of pediatric feeding disorders based on applied behavior analysis (ABA) have the most empirical support in the research literature (Volkert & Piazza, 2012); however, professionals often recommend, and caregivers often use, treatments that have limited empirical support. In the current investigation, we compared a modified sequential oral sensory approach (M‐SOS; Benson, Parke, Gannon, & Muñoz, 2013) to an ABA approach for the treatment of the food selectivity of 6 children with autism. We randomly assigned 3 children to ABA and 3 children to M‐SOS and compared the effects of treatment in a multiple baseline design across novel, healthy target foods. We used a multielement design to assess treatment generalization. Consumption of target foods increased for children who received ABA, but not for children who received M‐SOS. We subsequently implemented ABA with the children for whom M‐SOS was not effective and observed a potential treatment generalization effect during ABA when M‐SOS preceded ABA.  相似文献

The Big Five personality dimension Openness/Intellect is the trait most closely associated with creativity and creative achievement. Little is known, however, regarding the discriminant validity of its two aspects—Openness to Experience (reflecting cognitive engagement with perception, fantasy, aesthetics, and emotions) and Intellect (reflecting cognitive engagement with abstract and semantic information, primarily through reasoning)—in relation to creativity. In four demographically diverse samples totaling 1,035 participants, we investigated the independent predictive validity of Openness and Intellect by assessing the relations among cognitive ability, divergent thinking, personality, and creative achievement across the arts and sciences. We confirmed the hypothesis that whereas Openness predicts creative achievement in the arts, Intellect predicts creative achievement in the sciences. Inclusion of performance measures of general cognitive ability and divergent thinking indicated that the relation of Intellect to scientific creativity may be due at least in part to these abilities. Lastly, we found that Extraversion additionally predicted creative achievement in the arts, independently of Openness. Results are discussed in the context of dual‐process theory.  相似文献

To explore the significance of repeated memories for individuals' personal histories, we compared the characteristics of young adults' unique and repeated memories of childhood experiences. Memory type (unique vs. repeated) was a within-participant variable. In Experiment 1, college-age participants generated as many early memories as possible in 4 minutes; in Experiment 2, another sample provided complete reports of five early memories in each condition. In both experiments, participants rated the vividness, biographical importance and personal meaning of each memory and labelled the accompanying emotion. Unique memories were more vivid than repeated memories as well as more likely to include negative emotion, regardless of the method of reporting. Most importantly, college students rated their memories for unique and repeated events as equivalently infused with personal meaning. Analysis of the content of the memories reported in Experiment 2 established that unique and repeated memories did not differ in word count or percentages of perceptual terms or words indicating positive affect, although unique memories contained a greater percentage of negative affect. Additional analyses of content provided evidence for differences in the functions served by unique and repeated memories. The results have implications for the study of autobiographical memory and for identifying over-general memories.  相似文献

Efficient detection of threat provides obvious survival advantages and has resulted in a fast and accurate threat-detection system. Although beneficial under normal circumstances, this system may become hypersensitive and cause threat-processing abnormalities. Past research has shown that anxious individuals have difficulty disengaging attention from threatening faces, but it is unknown whether other forms of threatening social stimuli also influence attentional orienting. Much like faces, human body postures are salient social stimuli, because they are informative of one’s emotional state and next likely action. Additionally, postures can convey such information in situations in which another’s facial expression is not easily visible. Here we investigated whether there is a threat-specific effect for high-anxious individuals, by measuring the time that it takes the eyes to leave the attended stimulus, a task-irrelevant body posture. The results showed that relative to nonthreating postures, threat-related postures hold attention in anxious individuals, providing further evidence of an anxiety-related attentional bias for threatening information. This is the first study to demonstrate that attentional disengagement from threatening postures is affected by emotional valence in those reporting anxiety.  相似文献

Parents’ aspirations shape children’s development. In this study, over 6700 pregnant women and over 4300 of their partners from the Growing Up in New Zealand cohort responded to a question about their hopes, dreams, and expectations for their unborn children. Responses were coded according to a Maslowian hierarchy of needs. Mothers and their partners predominantly mentioned self-actualization and physiological aspirations for their unborn children, but their responses varied as a function of parental ethnicity and level of educational achievement and less so as a function of socioeconomic status. Mothers of European ethnicity, and parents with higher levels of educational achievement, mentioned more aspirations for their children—especially for self-actualization and belonging—than mothers of non-European ethnicity and parents with lower levels of educational achievement. These findings are discussed with respect to Maslowian theory and cultural developmental theories, and in terms of understanding the aspirations of parents from diverse backgrounds.  相似文献
