Both anecdotal evidence and recently reported research suggest that people are risk-averse when faced with waiting time decisions. Four studies investigate whether there is a self-other discrepancy in how people make waiting time decisions themselves and how they predict others will make similar decisions. People are found to believe that others have valuations of time similar to their own. However, when faced with alternatives that involve risk in the duration of the wait, the results point to a self-other discrepancy, in that people report greater risk-aversion themselves than they think others would. Further, when faced with waiting time gains, people are themselves more risk-averse than they think others would be. Conversely, when faced with waiting time losses, people are themselves more risk-seeking than they think others would be. Overall, the results are consistent with the recently proposed risk-as-feelings hypothesis. 相似文献

Older persons are among the major marginalized, disenfranchised citizens worldwide, yet this group has generally been ignored in the community psychology literature. In this paper, we trace the demographic trends in aging worldwide, and draw the field’s attention to the United Nations Program on Aging, which structures its policy recommendations in terms of concepts that are familiar to community psychologists. A central theme of the paper is that community psychology can have a role in producing the conceptual shifts needed to change societal attitudes now dominated by negative age stereotypes. 相似文献

We propose that negative affect can induce people to engage in risky decisions. We test two alternative hypotheses as to how this effect may emerge. The mood repair hypothesis states that risky choices in risk decision making serve as a means to repair one's negative affect. The depletion hypothesis, in contrast, states that risky choices in risk decision making are the mere consequence of a state of depletion resulting from engagement in active mood regulation attempts. The results of a first laboratory study establish a link between risky choices in risk decision making and negative affect. Subsequent experiments provide evidence that depletion due to active mood regulation attempts, rather than mood repair, is the underlying process for this link.

In four studies, student and nonstudent participants evaluated the possible outcomes of binary decisions involving health, safety, and environmental risks (e.g., whether to issue a dam‐failure evacuation order). Many participants indicated that false positives (e.g., evacuation, but no dam failure) were better than true negatives (e.g., no evacuation and no dam failure), thereby implying that the more protective action dominated the less protective action. A common rationale for this response pattern was the precautionary maxim “better safe than sorry.” Participants apparently evaluated outcomes partly on the basis of the decisions that might lead to them, in conflict with consequentialist decision models. Consistent with this explanation, the prevalence of implied dominance decreased substantially when the emphasis on decisions was reduced. These results demonstrate that an initial preference for a decision alternative can alter the evaluation of possible consequences of both the preferred alternative and a competing alternative, suggesting positive feedback loops that reinforce the initial preference. The rationality of considering the decision itself as an attribute of possible outcomes is discussed. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

In three studies we addressed the impact of perceived risk and negative affect on risky choice. In Study 1, we tested a model that included both perceived risk and negative affect as predictors of risky choice. Study 2 and Study 3 replicated these findings and examined the impact of affective versus cognitive processing modes. In all the three studies, both perceived risk and negative affect were shown to be significant predictors of risky choice. Furthermore, Study 2 and Study 3 showed that an affective processing mode strengthened the relation between negative affect and risky choice and that a cognitive processing mode strengthened the relation between perceived risk and risky choice. Together, these findings show support for the idea of a dual‐process model of risky choice. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

This paper provides an opportunity to consider the concept of community practice from the vantage point of community psychology. The author argues that community psychology has significant potential to change organizations, communities, and other settings to benefit setting occupants. However, it is the author's contention that the full realization of this potential is contingent upon an organized effort to engage in formal community practice. The author defines community practice in terms of four skill sets related to mobilization, planning, implementation, and evaluation. The author also describes settings that might support community practice and discusses implications for training and the field of community psychology in general. Finally, the author illustrates several community practice skills and roles in the context of a local community-based initiative in Ohio called Partnerships for Success. 相似文献

The effects of manipulations of response requirement, intertrial interval (ITI), and psychoactive drugs (ethanol, phencyclidine, and d-amphetamine) on lever choice under concurrent fixed-ratio schedules were investigated in rats. Responding on the \"certain' lever produced three 45-mg pellets, whereas responding on the \"risky\" lever produced either 15 pellets (p = .33) or no pellets (p .67). Rats earned all food during the session, which ended after 12 forced trials and 93 choice trials or 90 min, whichever occurred first. When the response requirement was increased from 1 to 16 and the ITI was 20 s, percentage of risky choice was inversely related to fixed-ratio value. When only a single response was required but the ITI was manipulated between 20 and 120 s (with maximum session duration held constant), percentage of risky choice was directly related to length of the ITI. The effects of the drugs were investigated first at an ITI of 20 s, when risky choice was low for most rats, and then at an ITI of 80 s, when risky choice was higher for most rats. Ethanol usually decreased risky choice. Phencyclidine did not usually affect risky choice when the ITI was 20 s but decreased it in half the rats when the ITI was 80 s. For d-amphetamine, the effects appeared to he related to baseline probability of risky choice; that is, low probabilities were increased and high probabilities were decreased. Although increase in risky choice as a function of the ITI is at variance with previous ITI data, it is consistent with foraging data showing that risk aversion decreases as food availability decreases. The pharmacological manipulations showed that drug effects on risky choice may be influenced by the baseline probability of risky choice, just as drug effects can be a function of baseline response rate. 相似文献

Previous research has documented a tendency for people to make more risk‐seeking decisions for others than for themselves in relationship scenarios. Two experiments investigated whether this self–other difference is moderated by participants' self‐esteem and anxiety levels. In Experiment 1, lower self‐esteem and higher anxiety levels were associated with more risk‐averse choices for personal decisions but not for decisions for others. Therefore, participants with lower self‐esteem/higher anxiety showed greater self–other differences in comparison to participants with higher self‐esteem/lower anxiety levels. Experiment 2 demonstrated that this effect was largely mediated by participants' expectations of success and feelings about potential negative outcomes. These results are discussed in the context of “threats to the self,” with a central role played by anxiety and self‐esteem threats in personal decision making but not in decision making for others.

Two studies tested whether people interpreted verbal chance terms in a self‐serving manner. Participants read statements describing the likelihood of events in their own future and in the future of a randomly chosen other. They interpreted the chance terms numerically. Chance terms were interpreted as denoting a higher probability when they were used to describe the likelihood of pleasant events in one's own future than when they were used to describe the likelihood of pleasant events in someone else's future (Study 1). Similarly, chance terms were interpreted as denoting a lower probability when they were used to describe the likelihood of unpleasant events in one's own future than when they were used to describe the likelihood of unpleasant events in someone else's future (Studies 1 and 2). These differences occurred primarily when the risk statements were threatening. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

The purposes of this study were to model the development of indirect aggression among a nationally representative sample of 1,401 Canadian children aged 4 at T2, 6 at T3, 8 at T4 and 10 at T5, and to examine predictors of trajectory group membership from T1 (age 2) child, familial, and parenting variables. Using a semi-parametric group-based modeling approach, two distinct trajectories were identified: \"increasing users\" comprising of 35% of the sample and \"stable low users\" comprising of 65% of the sample. Using logistic regression analyses to distinguish these two groups, we found that for girls, more frequent, increasing use of indirect aggression was associated with prior prosocial and physically aggressive behavior, low SES and low parental social support at age 2. For boys, increasing use of indirect aggression was associated with prior parenting issues at age 2-inconsistency and less positive parent-child interactions. Although this study provides unique information regarding the early development of indirect aggression and its predictors, more longitudinal research is needed to fully understand its development. 相似文献
