This study examined the cognitions thought to mediate the impact of context on adolescent substance use and also the extent to which context moderates the relations between these cognitions and use. Risk cognitions and behaviors were assessed in a panel of 746 African American adolescents (M age 10.5 at Wave 1, 12.2 at Wave 2). Results indicated that adolescents living in high-risk neighborhoods were more inclined toward substance use and more likely to be using at Wave 2. These context effects were mediated by the adolescents' risk cognitions: their risk images, willingness to use, and intentions to use. Also, context moderated the relation between willingness and use (the relation was stronger in high-risk neighborhoods) but it did not moderate the intentions to use relation. 相似文献

This study examines the role of individual difference variables in opportunistic claiming after service failure. Drawing on research in the conflict literature, social value orientation (SVO) and conflict style are investigated as possible influences. The results suggest that both SVO and conflict style impact the amount claimed and opportunistic behavior. This research provides additional insight into why claiming behavior varies even when consumers have the same experience. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

Perceived racial discrimination, self-control, anger, and either substance use or use cognitions were assessed in 2 studies conducted with samples of African American adolescents. The primary goal was to examine the relation between discrimination and self-control over time; a 2nd goal was to determine whether that relation mediates the link between discrimination and substance use found in previous research. Study 1, which included a latent growth curve analysis with 3 waves of data, indicated that experience with discrimination (from age 10 years to age 18 years) was associated with reduced self-control, which then predicted increased substance use. Additional analyses indicated anger was also a mediator of this discrimination to use relation. Study 2, which was experimental, showed that envisioning an experience involving discrimination was associated with an increase in substance-related responses to double entendre words (e.g., pot, roach) in a word association task, especially for participants who were low in dispositional self-control. The effect was again mediated by reports of anger. Thus, the "double mediation" pattern was discrimination → more anger and reduced self-control → increased substance use and/or substance cognitions. Results are discussed in terms of the long-term impact of discrimination on self-control and health behavior. Implications for interventions aimed at ameliorating the negative effects of discrimination and low self-control on health are also discussed. 相似文献

Three studies tested the hypothesis that the relation between perceived racial discrimination and substance use reported in previous research is moderated by use of substances as a coping mechanism. Studies 1 and 2 were experimental studies of African American adolescents' and young adults' reactions to a discrimination experience. Results revealed that those who endorsed substance use-as-coping reported more willingness to use substances after experiencing discrimination. Study 3 was a prospective study of the relation between perceived discrimination and substance use over an 8-year period in African American adolescents. Results demonstrated that discrimination is associated with increases in substance use, but only among adolescents who endorse substance use-as-coping. Together, these three studies provide evidence that experiencing discrimination has both short- and long-term detrimental effects on African Americans' substance use, but significantly more so for those who adopt a pattern of using substances as a coping mechanism.

Hilary Putnam introduced a puzzle about a citizen of the 17th century who speculates that some mysterious bones are over a million years old. I compare this situation, where the speculation is ahead of the method of carbon dating, with speculating about (1) a mathematical theorem before there is a proof, and (2) a riddle before there is an answer. All these cases are helpfully illuminated by Meno's paradox and, especially, Wittgenstein's philosophy of mathematics. I draw some conclusions about Wittgenstein's methodology both in his philosophy of mathematics and his more general philosophy, focusing on the roles of local perspicuity and changing our way of looking at things. 相似文献

Two appearance-based interventions designed to increase sun protection intentions and behaviors were evaluated. Sixty-eight college students in Experiment 1 and 76 beachgoers in Experiment 2 were randomly assigned to receive or not receive a photoaging (premature wrinkling and age spots) information intervention and, separately, to receive or not receive a novel ultraviolet (UV) photo intervention that makes the negative-appearance consequences of UV exposure more salient. Both experiments indicated that the UV photo intervention significantly increased intentions to use sunscreen in the future. A follow-up conducted with the beach sample indicated that UV photo information also produced greater protective behaviors for incidental sun exposure and that the combination of UV photo and photoaging information resulted in substantially lower reported sunbathing. 相似文献

The effects of success and failure on task performance, and attributions about performance, were compared for high and low instrumental college women. For the high instrumental group, success facilitated task performance, whereas failure, had no debilitating effect; for the low instrumental group, success had no effect on subsequent performance, whereas failure interfered with it. High instrumental women attributed their success primarily, to internal factors and their failures to external factors (the "egotistical" attribution profile) whereas low instrumental women revealed the opposite profile. The gender-appropriateness of the task had little effect on performance or attribution. Four potential mediators of these differences were investigated: self-esteem, perceived ability, expectancy of success, and attainment value. High-instrumental women's higher perceived ability and performance expectations accounted for their superior task performance, but none of the four mediators accounted for the relationship of instrumentality to attributions. 相似文献

The affiliation preferences of 151 adult heavy smokers who joined smoking cessation groups were assessed at the 1st group session and were then used to predict their smoking status 6 and 12 months later. Those who preferred to be in groups with other smokers who were having relatively little trouble quitting were more likely to be successful than were those who preferred others who were having more difficulty quitting. This prospective effect was mediated by psychological distancing from the image of the typical smoker: Preference for others who were doing well was associated with a decrease in perceived similarity to the typical smoker, which, in turn, was associated with successful cessation. Implications of these findings for cessation groups and social comparison theory are discussed. 相似文献

Two laboratory studies were conducted in which a new type of intervention was used to reduce ultraviolet radiation (UV) exposure from tanning booth use among college students (Time 1 Ns=70 and 134). The intervention uses UV photography to highlight the damage to facial skin caused by previous UV exposure. When the authors controlled for baseline measures of booth use, students in both studies who viewed their UV photographs reported less booth use at a follow-up session 3-4 weeks later than did students not shown a copy of their photograph. Also, in both studies, the decline in use was significantly mediated by a Tanning Cognition Index composed of variables suggested by the prototype-willingness (prototype) model of health risk: tanning attitudes, tanner prototypes, and willingness to engage in risky UV exposure. 相似文献
