Media contents that glorify risk-taking (e.g., video games that simulate illegal street racing, TV depictions of dangerous extreme sports or stunts) are becoming increasingly popular. Theory and research suggest that risk glorification is associated with risk-taking among the audience. Until recently the evidence was limited in three ways: First, most studies, being correlational, did not permit clear causal inferences. Second, we did not know the strength of the effect of different types of media and different types of risk-taking outcomes. Third, early research did little to isolate the underlying psychological processes that mediate the pernicious effects of risk glorifying media formats. In order to address these open questions we review the results of an experimental programme of research and the findings of a comprehensive meta-analysis. The main findings are that (a) the risky media contents do indeed have causal force; (b) according to our meta-analysis active participation in risk glorifying media interfaces has a larger effect than passive consumption; (c) psychological processes include the priming of risk-related constructs, effects of risk-positive situational heuristic cues, perceived social norms, personal risk habituation, and changes in the recipient's self-concept. To integrate these findings we propose a theoretical framework derived from broad-range socio-cognitive models. We conclude with a discussion of possible directions for future research.  相似文献

Perseverative responding is often seen in children’s performance in a variety of contexts. One such context is symbolic comprehension in which 2- and 2½-year-olds demonstrate difficulty in appreciating the association of symbols (pictures and scale models) and their referents and show a high proportion of perseverative responding. Representational-level explanations of perseveration were explored in the current studies via examination of the impact of perceptual similarity of visual environments across trials. Across two experiments, children saw either a picture (Experiment 1) or a scale model (Experiment 2) of a hiding location of a room and were then encouraged to recover the toy from an identical room. Manipulating the perceptual similarity of the environments across successive trials affected performance and perseverative responding. These results highlight the critical role played by perceptual information not only in symbolic tasks but also in many other tasks and have important implications for theories of perseveration.  相似文献

The aim of this study was to investigate the reliability and validity of the computer based application of the Secret Agent (SA) task of risk-taking and moral decision-making. The participants were 100 male patients in a maximum security hospital (50 with severe mental illness and 50 with personality disorder) and 50 community based healthy controls. All participants completed the SA task, the Iowa Gambling Task (IGT), and measures of IQ, antisocial personality traits, sensation-seeking, impulsivity and sociomoral reasoning. The SA risk-taking and moral decision-making scales had satisfactory levels of reliability (Cronbach’s alpha). Risk-taking correlated significantly with sensation-seeking across all three participant groups. In contrast, risk-taking only correlated with impulsivity among the severe mental illness group. Moral decision-making correlated with sociomoral reasoning among the personality disorder group. No correlation was found between the SA scores and the IGT score and the IGT did not correlate with sensation-seeking or impulsivity. IQ and antisocial personality traits did not correlate with the SA or IGT scales. The study highlights the importance of context, the nature of the risk-taking task, and ‘problem framing’ of the instructions in their relationship with individual differences.  相似文献

Using the modified Dimensional Change Card Sort task, we examined the influence of positive affect on task switching by inspecting various markers for the costs, including restart cost, switch cost and mixing cost. Given that the executive-control processes that underlie switching performance—i.e., inhibition or shifting—are distinct from the component processes that underlie non-switching performance—i.e., stimulus evaluation, resource allocation or response execution—we hypothesised that if positive affect facilitates task switching via executive-control processes, rather than via component processes, positive affect would reduce both switch and restart costs, but not mixing cost, because both switch and restart costs rely on executive processes, while mixing cost imposes only minimal demands on executive processes. We found beneficial effects of positive affect on both restart and switch costs, but not on mixing costs. These results suggest that positive affect improves switching abilities via executive processes rather than via component processes.  相似文献

A popular theoretical assumption holds that task-related disagreements stimulate critical thinking, and thus may improve group decision making. Two recent meta-analyses showed, however, that task conflict can have a positive effect, a negative effect, or no effect at all on decision-making quality (De Dreu & Weingart, 2003; De Wit, Greer, & Jehn, 2012). In two studies, we built upon the suggestion of both meta-analyses that the presence of relationship conflict determines whether a task conflict is positively or negatively related to decision making. We hypothesized and found that the level of perceived relationship conflict during task conflict (Study 1), and the actual presence (vs. absence) of relationship conflict during task conflict (Study 2), increased group members’ rigidity in holding onto suboptimal initial preferences during decision making and thus led to poor decisions. In both studies the effect of relationship conflict on decision making was mediated by biased use of information.  相似文献

We examine the association between neighborhood socio-economic disadvantage and perceived stress during middle and late adolescence among African American youth (N = 665; 51 % female; M = 15.9 years at baseline). In addition, we explored the ways through which neighborhood stressors interacted with an individual’s intra- and interpersonal resources (e.g., coping, social support and substance use), to affect their perceived stress trajectories during adolescence. First, we tested a neighborhood stressors model and found that youth who lived in neighborhoods with greater socioeconomic disadvantage had higher baseline stress and a steeper increase in stress over time. When we included individual-level risk and promotive factors in the model, however, the effect of neighborhood disadvantage on perceived stress was no longer significant, and the stress trajectory was explained by adolescent substance use, social support and perceptions of the neighborhood. Our results support theories of stress and coping, and the importance of proximal intra- and interpersonal factors in either amplifying or mitigating perceptions of stress. We discuss implications of the neighborhood context and how our findings may inform future prevention and intervention related to adolescent stress and development.  相似文献

This study assessed the unique associations of risk perceptions and worry with attitudes about genetic testing for breast cancer susceptibility. Women (general practitioner clinic attenders, university students, and first-degree relatives of breast cancer survivors; N?=?303) read information about genetic testing and completed measures assessing perceived cancer risk, cancer worry, and genetic testing attitudes and beliefs. Worry was associated with greater interest in genetic testing, stronger beliefs that testing has detrimental emotional consequences, and positive beliefs about benefits of testing and risk-reducing surgeries. Perceived risk was unrelated to interest and associated with more skeptical beliefs about emotional consequences and benefits of testing and risk-reducing surgeries. At low worry levels, testing interest increased with more positive beliefs about testing benefits; at high worry levels, interest was high regardless of benefits beliefs. The findings support Leventhal's Common-Sense Model of self-regulation delineating interactive influences of risk-related cognitions and emotions on information processing and behavior.  相似文献

Many women may be reluctant to perform breast self-examination (B.S.E.) regularly due to motivational or self-regulatory deficits. The Health Action Process Approach (Schwarzer, R. (1992). Self-efficacy in the adoption and maintenance of health behaviors: theoretical approaches and a new model. In: Schwarzer, R. (Ed.), Self-efficacy: Thought Control of Action , pp. 217-243. Hemisphere, Washington DC; Schwarzer, R. (2001). Social-cognitive factors in changing health-related behavior. Current Directions in Psychological Science , 10 , 47-51.), a health behavior change model that advocates the separation of motivation and action phases, such as goal setting and goal pursuit, was applied to data from 418 young women whose risk perceptions, outcome expectancies, self-efficacy, intention to perform B.S.E., planning, and reported examination behaviors were examined at two points in time. Risk perception was found to have a negligible influence in a path analysis, whereas self-efficacy emerged as the best predictor of intention and planning. Planning, in turn, appeared to be the best predictor of B.S.E. behaviors, followed by self-efficacy. The results point to the influential role that self-regulatory strategies (such as planning) play in translating goals into action. The study contributes to the current debate on stage theories of health behavior change and the orchestration of self-beliefs and strategies in the context of goal-directed behaviors.  相似文献

Psychosocial correlates of alexithymia were examined in 102 healthy, older adults (ages 53-83; 76% male). Alexithymic ( n = 26) and non-alexithymic ( n = 30) groups, defined by top ( S 70) and bottom ( h 54) quartiles of the distribution of Toronto Alexithymia Scale (26-item) scores, were compared with respect to psychosocial, psychophysiological, and biomedical risk factors for cardiovascular disease. Both categorical ratings and continuous scores of alexithymia were associated with significantly greater levels of trait anxiety, anger-in, neuroticism, hostility, perceived stress, depression, and lower levels of social support. Compared to non-alexithymics, alexithymics displayed significantly greater blood pressure responses to anger provocation and tended to have a greater percent body fat. The groups did not differ in resting cardiovascular parameters, heart rate reactivity, fasting glucose and lipoprotein lipids, body mass index, waist-to-hip ratio, social desirability, or trait anger. These findings suggest several psychosocial and psychophysiological pathways by which alexithymia may confer risk for cardiovascular disease among older adults.  相似文献

When Klein, W. M. gave participants absolute and comparative risk information (crossed experimentally) they were more disturbed by being above than below average, but not by being at higher rather than lower risk. The current experiment tests whether Klein's findings extend to situations involving lower risk figures more typical of genuine health risks, assesses participants’ understanding of the information, and directly compares responses of US and UK samples. Participants were presented with hypothetical information about comparative and absolute risks of deep vein thrombosis. There was a main effect of absolute risk information on disturbance and precaution intentions in the US sample, but no effects of comparative information on these measures in either sample. Understanding was poor among participants receiving both pieces of risk information. Future studies should include measures of understanding to establish whether people are failing to understand what they are told or failing to respond systematically to what they understand. Practically, the findings caution against providing comparative risk information when communicating low risk figures.  相似文献
