Studies in cognitive psychology, marketing, and education indicate that humor distracts attention from non‐humorous information presented at the same time. Two experiments investigated why humor distracts attention. The two basic components of humor comprise (1) incongruency resolution, which poses cognitive demands and (2) positive affect. We disentangled the contributions of cognitive demands and positive affect on distraction based on the notions that (a) both components are possible sources of distraction, and (b) the components were always confounded in previous research. In an evaluative conditioning paradigm, novel products were consistently paired with humorous stimuli, whereas other products were paired with stimuli that were either (1) equally demanding but neutral, (2) equally positive but undemanding, and (3) undemanding and neutral. The results showed that cognitively demanding stimuli distracted attention, irrespective of stimulus positivity. These findings suggest that the cognitive demands of humor, not the positive affect it evokes, underlie the distraction effect. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

Patterns of substance use are examined in a sample of over 1,200 youth in a non-metropolitan region of New England. Self-reported history and frequency of alcohol, tobacco, marijuana, inhalants, pain medications, and other hard drug use was assessed for 9th and 10th grade students. Latent class analyses identified four patterns of substance use: non-users (22%), alcohol experimenters (38%), occasional polysubstance users (29%), and frequent polysubstance users (10%). Contextual risk and protective factors in the individual, family, peer, and community domains predicted substance use patterns. Youth report of peer substance use had the largest effects on substance use class membership. Other individual characteristics (e.g., gender, antisocial behavior, academic performance, perceived harm from use), family characteristics (e.g., parental drinking, parental disapproval of youth use), and community characteristics (e.g., availability of substances) demonstrated consistent effects on substance use classes. Implications for prevention are discussed from a social-ecological perspective.  相似文献

Researchers recognize that the connection between alcohol and peer violence may relate to community level ecological factors, such as the location of businesses that sell alcohol. Building on previous research among adults, this study examines the relationship between alcohol outlet density and violent behaviors among adolescents, taking into account demographic characteristics, individual alcohol use, and neighborhood level socioeconomic indicators. Data drawn from a diverse Emergency Department based sample of 1,050 urban adolescents, combined with tract level data from the state liquor control commission and U.S. Census, were analyzed. Results of multivariate multi-level regression analysis indicate that alcohol outlet density is significantly related to adolescents’ violent behaviors, controlling for demographic characteristics and individual alcohol use. Census tract level socioeconomic indicators were not significantly associated with youth violence. Findings suggest that alcohol outlet density regulation should be considered as part of broader violence prevention strategies for urban adolescents.  相似文献

Complex research questions often cannot be addressed adequately with a single data set. One sensible alternative to the high cost and effort associated with the creation of large new data sets is to combine existing data sets containing variables related to the constructs of interest. The goal of the present research was to develop a flexible, broadly applicable approach to the integration of disparate data sets that is based on nonparametric multiple imputation and the collection of data from a convenient, de novo calibration sample. We demonstrate proof of concept for the approach by integrating three existing data sets containing items related to the extent of problematic alcohol use and associations with deviant peers. We discuss both necessary conditions for the approach to work well and potential strengths and weaknesses of the method compared to other data set integration approaches.  相似文献

Mediation analysis is a popular framework for identifying underlying mechanisms in social psychology. In the context of simple mediation, we review and discuss the implications of three facets of mediation analysis: (a) conceptualization of the relations between the variables, (b) statistical approaches, and (c) relevant elements of design. We also highlight the issue of equivalent models that are inherent in simple mediation. The extent to which results are meaningful stem directly from choices regarding these three facets of mediation analysis. We conclude by discussing how mediation analysis can be better applied to examine causal processes, highlight the limits of simple mediation, and make recommendations for better practice.  相似文献

We examined the relationship between the cumulative presence of major disease (cancer, stroke, diabetes, heart disease, and hypertension), social support, and self‐reported general and emotional well‐being in a community representative sample of predominantly White and African American respondents (N = 1349). Across all ages, greater presence of disease predicted poorer reported general health, and predicted lower emotional well‐being for respondents 40 and above. In contrast, social support predicted better‐reported general and emotional well‐being. We predicted that different types of social support (blood relatives, children, friends, community members) would be relatively more important for health in different age groups based on a lifespan or life stage model. This hypothesis was supported; across all ages, social support was related to better reported general and emotional health, but sources of support differed by age. Broadly, those in younger age groups tended to list familial members as their strongest sources of support, whereas older group members listed their friends and community members. As a whole, social support mediated the effect of disease on reported well‐being, however, moderated mediation by type of support was not significant. The results are consistent with a lifespan approach to changing social ties throughout the life course.  相似文献

Sandtray supervision and solution-focused supervision (SFS) are both strengths-based approaches that may be effective in helping counselor trainees reduce their anxiety and develop clinical self-confidence. The purpose of this collective case study was to explore how a group of practicum students with a school counseling emphasis experienced a blending of sandtray and solution-focused supervision (SFS) approaches. Participants described how the blended approach fostered group cohesiveness in their supervision and promoted both personal and professional development. Participants indicated more awareness of the impact of sandtray than the influence of the solution-focused approach in their supervision.  相似文献

ABSTRACT

Existing research finds adolescent popularity to be correlated with risk-taking. While a subset of this research uses longitudinal methods to examine whether part of this correlation may reflect the influence of popularity on risk-taking, research has paid insufficient attention to examining the reverse relation. Drawing on literature from a range of disciplines, we argue that a portion of the correlation reflects the positive influence of risk-taking on popularity. Using longitudinal data from a northeastern sample of adolescents, we test this argument. Net of statistical controls, we find that risk-taking among males, but not females, is associated with higher popularity, but that this relation is curvilinear, such that progressively higher levels of risk-taking yield diminishing returns in male popularity. Results provide one explanation for why male adolescents tend to take more risks in the presence of peers. Likewise, they suggest that attempts to prevent adolescent risk-taking, particularly among males, may require practitioners to move beyond conceiving of adolescent risk-taking as purely irrational behavior reflecting an ostensible inability to perceive potential consequences. Instead, results suggest that male risk-taking should be understood in the context of the salient social rewards that may make it rational from an adolescent perspective.  相似文献
