Partner Influences and Gender-Related Factors Associated with Noncondom Use Among Young Adult African American Women 总被引：12，自引：0，他引：12
We examined the partner influences and gender-related correlates of noncondom use among African American women. The prevalence of noncondom use was 45.3%. Women whose sexual partners were noncondom users were four times more likely to believe that asking their partner to use a condom implied he was unfaithful, three times as likely to have a partner who resisted using condoms, three times more likely to receive AFDC, twice as likely to be sexually nonassertive, three times more likely to believe that it was not difficult to find an eligible African American man, and three times as likely to have had one sexual partner. HIV prevention tailored towards African American women should address these partner influences and gender-related factors. 相似文献

Although decision makers often consult other people's opinions to improve their decisions, they fail to do so optimally. One main obstacle to incorporating others' opinions efficiently is one's own opinion. We theorize that decision makers could improve their performance by suspending their own judgment. In three studies, participants used others' opinions to estimate uncertain quantities (the caloric value of foods). In the full‐view condition, participants could form independent estimates prior to receiving others' opinions, whereas participants in the blindfold condition could not form prior opinions. We obtained an intriguing blindfold effect. In all studies, the blindfolded participants provided more accurate estimates than did the full‐view participants. Several policy‐capturing measures indicated that the advantage of the blindfolded participants was due to their unbiased weighting of others' opinions. The full‐view participants, in contrast, adhered to their prior opinion and thus failed to exploit the information contained in others' opinions. Moreover, in all three studies, the blindfolded participants were not cognizant of their advantage and expressed less confidence in their estimates than did the full‐view participants. The results are discussed in relation to theories of opinion revision and group decision making. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

We conducted a field study to investigate the secondary transfer effect of intergroup contact, consisting in the generalisation of the positive effects of intergroup contact to outgroups uninvolved in the contact situation. Italian secondary school students (N = 175) filled out a questionnaire; the effects of prior contact were statistically controlled. Results showed that contact with immigrants improved attitudes toward them. In turn, these attitudes generalised to attitudes toward two dissimilar outgroups not directly involved in contact: disabled and homosexuals. Notably, we found evidence for a secondary transfer effect of intergroup anxiety and perspective taking, which generalised from immigrants to the disabled and homosexuals. Evidence was found for the mediating role of intergroup attitudes, intergroup anxiety and perspective taking. The theoretical and practical implications of findings are discussed.

Previous studies suggest that those who naturally vary their pronoun use over the course of expressive writing subsequently report the greatest improvements in physical and mental health. To explore possible perspective taking or perspective switching effects, two studies manipulated writing perspectives about emotional events from either a first-person, second-person, or third-person perspective. In Study 1, 55 students were randomly assigned to one of the three writing perspectives and were asked to write from the same perspective for three 5-minute writing sessions. In Study 2, 129 students wrote for three 5-minute sessions, one from each perspective in a counterbalanced order. The results showed that writing from a first-person perspective conferred more perceived benefits and was associated with using more cognitive mechanism words, whether engaged in perspective taking or perspective switching. 相似文献

The current research examines tacit coordination behavior in a lottery selection task. Two hundred participants in each of three experiments and 100 in a fourth choose to participate in one of two lotteries, where one lottery has a larger prize than the other. Independent of variations in the complexity of the mechanism of prize allocation, the prize amounts, and whether the lottery is the participant's first or second choice, we typically find that the percentage of participants who choose the high versus low‐prize lotteries does not significantly differ from the equilibrium predictions. This coordination is achieved without communication or experience. We additionally find that participants with an analytical thinking style and a risk‐averse tendency are more likely to choose the low‐prize lottery over the high‐prize lottery. This tendency seems to be stable across choices. The pattern of our results suggests that to achieve tacit coordination, having a subset of individuals who attend to the choices of others is sufficient. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

The outcomes in many competitive tasks depend upon both skill and luck. Behavioral theories on risk taking in tournaments indicate that low‐skilled individuals may have incentives to take more risks than high‐skilled ones. We build on these theories and suggest, in addition, that when luck is more important in determining outcomes, the increase in risk taking is larger for low‐skilled than high‐skilled individuals. We test this hypothesis by analyzing stock analysts' forecasts of companies' earnings per share under market conditions that vary in volatility and thus imply different levels of luck in outcomes. Specifically, noting that forecasts that deviate widely from the consensus—which is observable by the analyst—potentially carry career‐related rewards but also reputational risks, we examine the degree of deviation from consensus exhibited by analysts of different skill levels (measured by both past forecasting accuracy and education) in different market conditions. We find that average deviations from consensus increase as markets become more volatile. At the same time, under conditions of high volatility, low‐skilled analysts exhibit larger increases in deviations from consensus than high‐skilled analysts. These field data results support our hypothesis based on of risk taking in tournaments. We discuss alternative interpretations such as, for example, self‐serving attributions and indicate directions for future research. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Despite a return of only $.53 on the dollar, state lotteries are extremely popular, especially among the poor, who play the most but can least afford to play. In two experiments conducted with low‐income participants, we examine how implicit comparisons with other income classes increase low‐income individuals' desire to play the lottery. In Experiment 1, participants were more likely to purchase lottery tickets when they were primed to perceive that their own income was low relative to an implicit standard. In Experiment 2, participants purchased more tickets when they considered situations in which rich people or poor people receive advantages, implicitly highlighting the fact that everyone has an equal chance of winning the lottery.

Decision‐makers' relative preferences for various advisor characteristics were investigated in two multilevel policy‐capturing studies. The characteristics under consideration were: advisor expertise, advisor confidence, advisor intentions, and whether that advisor was the sole available source of advice. In Study 1, decision‐makers had access to all relevant information about the advisors. In contrast, some relevant information about the advisors was systematically made unavailable in Study 2, which allowed an investigation of the effect of missing information on decision‐makers' evaluations of advisors. Results from both studies indicated that advisor expertise and intentions were most important in promoting decision‐makers' positive evaluations of advisors, that this effect was even more pronounced under conditions of missing information, and that advisor expertise and intentions also interacted synergistically. Given that expertise and good intentions are determinants of an advisor's trustworthiness, the results highlight the interpersonal nature of advice giving and taking.

We present two studies that evaluate how people combine advice and how they respond to outlying opinions. In a preliminary study, we found that individuals use discounting strategies when they encounter an extreme opinion in a small sample of opinions taken only once (a one‐shot advice‐taking situation). The main study examines the influence of outlying opinions (which may or may not be accurate) within a learning paradigm with feedback. This study shows that it is easy to reinforce a discounting strategy (with feedback) whereas it is more difficult to counteract this default strategy. In the discussion we consider cognitive, statistical, and strategic justifications for discounting opinions, from both theoretical and practical points of view.
