The psychophysiological correlates of risk recognition among victims and non-victims of sexual assault

This study examined the psychophysiological correlates of risk recognition in sexual victimization. Victims and non-victims of sexual assault listened to a hypothetical date rape interaction and were asked to indicate the point at which the man had become sexually inappropriate. Subjective and objective (physiology) measures of responding as well as a measure of risk recognition in reaction to the date rape scenario were analyzed to evaluate both between and within-subjects' differences. Results showed that, relative to non-victims, victims of sexual assault displayed significant differences in risk recognition as well as both subjective and objective measures of physiological reactivity. Overall, the results indicate that altered physiological responding to relevant threat cues may be related to individuals' ability to identify and react to threatening sexual situations.     

Obesity and body image

Modern western culture emphasizes thinness, denigrates excess weight, and stigmatizes obese individuals, making it likely that obese people internalize these messages and feel badly about the physical presence that brands them. There is clear evidence that obesity is linked with poor body image, but not all obese persons suffer from this problem or are equally vulnerable. Risk factors identified thus far are degree of overweight, being female, and binge eating, with some evidence of risk increasing with early age of onset of obesity, race, and several additional factors. Treatments do exist for improving body image in overweight individuals. Key questions are how to identify those in need of body image intervention, how such programs can be integrated with weight loss treatments, and ultimately, how body image distress can be prevented.     

Relations between risk perceptions and socio-political ideology are domain- and ideology- dependent

Public policy intended to address risks is largely determined by government officials who are typically elected by ‘the people’. Lay people presumably support political figures most likely to tackle the risks perceived as relevant. The present research investigated whether risk perceptions vary by risk domain and socio-political ideology. American community adults (N = 387) recruited using Amazon Mechanical Turk completed measures of right-wing authoritarianism (RWA), social dominance orientation (SDO), political conservatism, and perceived domain risks. Risk perceptions of conservatives versus liberals systematically differed by domain: Increases in political conservatism (vs. liberalism) and RWA were associated with perceiving “personal danger” hazards as more risky, whereas increases in SDO were associated with perceiving “competitive” hazards as less risky. A liberal-orientation was associated with heightened risk concerning collective (shared) hazards.     

Early family context and development of adolescent ruminative style: Moderation by temperament

We know very little about the development of rumination, the tendency to passively brood about negative feelings. Because rumination is a risk factor for many forms of psychopathology, especially depression, such knowledge could prove important for preventing negative mental health outcomes in youth. This study examined developmental origins of rumination in a longitudinal sample (N=337; 51% girls) studied in preschool (ages 3½ and 4½ years) and early adolescence (ages 13 and 15 years). Results indicated that family context and child temperament, assessed during the preschool period, were risk factors for a ruminative style in adolescence. Specifically, early family contexts characterised by over-controlling parenting and a family style of negative-submissive expressivity predicted higher levels of later rumination. These associations were moderated by children's temperamental characteristics of negative affect and effortful control. Further, the interaction of these temperament factors exerted an additional influence on later rumination. Implications for prevention and intervention efforts are discussed.     

任务框架及利他人格对社会折扣的影响

与自我存在一定社会距离的他人获得收益或遭受损失都会给自我带来一定的效用,这种效用随着与他人间社会距离的增加而减少,该现象被称为社会折扣。本研究采用情境式选择滴定程序,探索并比较了“为他人得益而放弃自我得益”(NG-G)、“为他人不失而放弃自我得益”(NG-NL)、“为他人得益而承担自我损失”(L-G)以及“为他人不失而承担自我损失”(L-NL)4种任务框架下的社会折扣程度。结果发现：(1)4种框架下,指数模型均比双曲模型更好地描绘了被试的社会折扣规律;(2)任务框架影响社会折扣程度,“为他人不失”框架下(含NG-NL、L-NL)的折扣程度比“为他人得益”框架下(含NG-G、L-G)低;(3)任务框架与社会距离的交互作用影响社会折扣程度。随着社会距离增加, NG-G与NG-NL框架下折扣程度的差异逐渐变小, L-G与L-NL框架下折扣程度的差异也逐渐变小;(4)社会距离与利他人格的交互作用显著,高低利他人格者的社会折扣程度只在社会距离较远时存在显著差异。上述结果表明,个体不仅存在自我损失规避倾向,也存在不同程度的他人损失规避倾向。     

Perception of health risks: How smoker status affects defensive optimism

Abstract

People generally underestimate their risk to come down with a life-threatening disease when comparing themselves to similar others. However, to some extent they do take objective risk status or actual risk behavior into account. The present study examined specific conditions of this phenomenon. It was found that smoker status was associated with a somewhat higher perceived risk of getting lung cancer or smoker's cough or having a heart attack, but not of coming down with other diseases. Still, smokers did not admit that they had an above-average risk for these maladies, thus reflecting defensive optimism. In addition, smokers characterized the behavior of an abstract person, a “risk stereotype”, by estimating the number of years of smoking, the daily number of cigarettes, and the cigarettes' nicotine content necessary to be at high risk for lung cancer. There was evidence that smokers used these risk stereotypes as a reference point for evaluating their own relative risk. Smokers also made higher risk estimates if their own behavior approached that of the risk stereotype. On the whole, the results suggest that people use subjective risk factor theories when estimating their own personal health risks.     

Changes in Negative Reciprocity as a Function of Age

Standard economic models assume people exclusively pursue material self‐interests in social interactions. However, people exhibit social preferences; that is, they base their choices partly on the outcomes others obtained in a social interaction. People care about fairness, and reciprocity affects behavior. This study examines the differences in negative reciprocity (costly punishment for unfair divisions) as a function of age. Sixty‐one kindergarteners (5‐year‐olds), 53 second graders (8‐year‐olds), and 57 sixth graders (12‐year‐olds) played a dictator game or a mini–ultimatum game either with a human proposer or with a random machine that determined the division between the two players. By keeping the divisions between the players constant and varying the source of the unfair proposal, we were able to differentiate between reciprocity‐based and inequality‐aversion preferences. We found that kindergarteners proposed and accepted unfair divisions regardless of the source of the offer, behaving according to the standard economic model. Children in the sixth grade tended to reject unfair offers from a human proposer but accept unfair divisions from a random device, indicating the emergence of negative reciprocity preferences by age eight (and contrary to inequality aversion). Children at this age also tended to give more fair offers in the ultimatum game than in the dictator game, indicating the emergence of strategic thinking.

The effect of message framing and the nature of the targeted illness on individuals’ intention to participate in clinical trials

IntroductionClinical trials are considered as the most useful methods to evaluate the efficacy of new medical treatments, but the participation of healthy individuals is often too small, which limits the statistical power of the trial and hence its effectiveness.ObjectiveThe goal of the present research is to assess, for the first time, the effects of message framing (gain versus loss) and of the nature of the illness targeted by a clinical trial (highly- versus mildly-contagious) on individuals’ intention to enter it.MethodsThe experimental manipulation is carried out within a scenario promoting a clinical trial, in a 2 (framing: gain vs loss) × 2 (nature of the illness: highly- vs mildly-contagious) between-participants design. After reading the scenario, participants were asked to rate their intention to enter the trial and their perception of its utility.ResultsStatistical analyses validated a causal model explaining that a gain-framed message describing a highly-contagious illness increases the perception of the utility of the clinical trial, which in turn enhances the intention to participate.ConclusionThe discussion mainly focuses on the contributions of these findings at a theoretical level, considering the limits and potential of their possible application.     

Get the Message: Targeting Beliefs to Develop Risk Reduction Intervention Messages for African American Adolescents

Risk reduction interventions that promote condom use, a vital component of most HIV prevention interventions, have been successful in increasing condom use among African American adolescents. Understanding theoretical components that lead to behavior change and selecting relevant risk reduction messages remain important considerations for targeting new interventions and tailoring existing interventions. The present study sought to (1) identify the most important theoretical determinants of condom use intention in African American adolescent males and females, separately, using the integrative model of behavior prediction, and (2) identify underlying beliefs within the determinants that were good candidates for message development in similar interventions. Using 446 African American adolescents, multi‐group SEM indicated that the gender‐specific IM exhibited a better fit than the overall model. Specifically, the IM had a stronger capacity for predicting condom use intention and condom use behavior for adolescent boys. Using a specific criteria for message selection, specific condom use beliefs were discussed as potential candidate messages for both African American males and females.
