The tendency to overestimate has consistently been reported in studies of reachability estimation. According to one of the more prominent explanations, the postural stability hypothesis, the perceived reaching limit depends on the individual's perceived postural constraints. To test that proposition, the authors compared estimates of reachability of 38 adults (a) in the seated posture (P1) and (b) in the more demanding posture of standing on one foot and leaning forward (P2). Although there was no difference between conditions for total error, results for the distribution and direction of error indicated that participants overestimated in the P1 condition and underestimated in the P2 condition. It therefore appears that perceived postural constraints could be a factor in judgments of reachability. When participants in the present study perceived greater postural demands, they may have elected to program a more conservative strategy that resulted in underestimation. 相似文献
The purpose of this study is to examine the major determinants of psychological health during unemployment. With this in mind, 438 (17% female and 83% male) unemployed individuals were contacted through Turkey's State Employment Office. It was expected that the relationship between duration of unemployment and psychological wellbeing would be nonlinear. Additionally it was hypothesized that perceived social support would moderate the relationship between length of unemployment and psychological health. Further, we suggested that self‐esteem would be related to psychological health and moderate the relationship between length of unemployment and psychological health. The results supported the curvilinearity hypothesis of the relationship between unemployment duration and psychological health as measured by General Health Questionnaire. However, social support was not found to moderate the relationship between unemployment duration and psychological health. The hypothesis that self‐esteem would moderate the relationship between length of unemployment and psychological distress was not supported, although self‐esteem was a strong negative determinant of psychological distress during unemployment. Regression analysis showed that the best predictors of psychological health were self‐esteem, perceived social support and perceived adequacy of financial aid received from relatives. Interestingly, perceived adequacy of the financial aid was negatively related to psychological health. This result was contradictory with the previous literature pointing out that financial aid reduces the effects of poverty due to unemployment. The findings of this study are important since the relationship between unemployment duration and psychological health was nonlinear, indicating that relevant services should be especially careful to intervene to increase social support and self‐esteem during these critical times. The other results and limitations are discussed. 相似文献
This study examined the role of perceived health in predicting theoretically‐relevant aspects of smoking behavior among 161 young adult regular smokers (67 females; mean age = 21.9 years (SD = 7.2), cigarettes per day (M) = 12.2 (SD = 5.7)) recruited from the general community. Consistent with prediction, results indicated that relative to anxiety sensitivity, gender, number of cigarettes smoked per day and nicotine dependence, perceived physical health uniquely and significantly predicted expectancies for negative affect reduction and expectancies that smoking would lead to negative personal consequences. Additionally, perceived health incrementally predicted motivation to smoke to reduce negative affect. In contrast to expectation, perceived health was unrelated to motivation to quit smoking. Results are discussed in relation to the role of perceived health as a cognitive vulnerability factor for specific types of smoking patterns. 相似文献
Despite the growing number of cross-cultural studies focusing on well-being, little is known about social support outside of western civilization, particularly among people in Middle Eastern cultures. The current study examined the relationships between perceived social support and components of subjective well-being (i.e. positive and negative affect, satisfaction with life) among college students in Iran, Jordan, and the United States. Perceived support from family significantly predicted each aspect of well-being within each country. However, perceived support from friends did not predict any component of well-being in Iran; yet, in Jordan and the US, friend support predicted higher levels of positive mood. These results will be examined in terms of roles and relationship norms in these countries. 相似文献
Among adolescents, religiosity has been associated with lower rates of marijuana use, though few studies have examined its impact on the perceived risk of use. There is strong support that perceived risk of using marijuana is negatively correlated with the frequency of use. We examined the relationship among religiosity, perceived risk, and marijuana use from a national survey of adolescents that contained questions about lifetime, weekly, and past month substance use, social support, religious involvement and attitudes, and perceived riskiness of use. We tested a structural equation model of relationships among latent variables of religiosity and perceived risk, and an observed variable of total days of marijuana use in the past 12 months. Results indicated the model was a good fit to the data and described a mediating relationship of perceived risk of use between religiosity and marijuana use. Implications for leveraging religiosity in prevention of substance use are discussed. 相似文献
Objective: Based on the Limited Capacity Model of Motivated Mediated Message Processing, this study explored the effects of smoking cues in antismoking Public Service Announcements (PSAs) on message processing among intermittent/light smokers and nonsmokers.
Method: A 2 (smoking cues: present vs. absent) × 2 (smoking status: smokers vs. nonsmokers) mixed experimental design was conducted. Self-report measures and two physiological measures including skin conductance and heart rate were examined.
Results: Messages with smoking cues generated higher levels of arousal (F = 4.57, p = .04), attention (F = 2.51, p = .04), positive message evaluation (F = 28.70, p < .001) and less intent to smoke (F = 26.60, p < .001). Intermittent and light smokers had much stronger reactions to messages containing tobacco-related visuals, including arousal (F = 4.10, p = .04), perceived ad effectiveness (F = 9.24, p = .03) and intent to smoke (F = 22.98, p < .001).
Implication: The antismoking arguments may have suppressed cue-induced smoking urges, which dampened negative persuasion outcomes. Limitations included the restricted generalisability and the focus on short-term effect. Future research may use a random sample of PSAs with a general population. 相似文献
