Intoxicated witnesses are common, making it important to understand alcohol's impact on witness accuracy and suggestibility. Participants assigned to an immediate retrieval condition encoded and recalled in one of the three intoxication conditions: sober control, placebo, or intoxicated. Participants in the delayed retrieval condition were assigned to encode in one of the three intoxication conditions, returned a week later, and were assigned to retrieve in one of the three intoxication conditions. Intoxication condition at encoding was fully crossed with intoxication condition at retrieval in the delayed condition. Participants encoded a mock crime video and retrieved via a forced‐choice test, with answers already circled (purportedly by a prior participant); half of the precircled responses were incorrect. When recalling after a delay only, intoxication at encoding increased agreement with incorrect suggested answers and decreased accuracy. Results suggest intoxicated witnesses may benefit from being interviewed immediately rather than after a sobering delay.  相似文献

Approach–avoidance paradigms create a competition between appetitive and aversive contingencies and are widely used in nonhuman research on anxiety. Here, we examined how instructions about threat and avoidance impact control by competing contingencies over human approach–avoidance behavior. Additionally, Experiment 1 examined the effects of threat magnitude (money loss amount) and avoidance cost (fixed ratio requirements), whereas Experiment 2 examined the effects of threat information (available, unavailable and inaccurate) on approach–avoidance. During the task, approach responding was modeled by reinforcing responding with money on a FR schedule. By performing an observing response, participants produced an escalating “threat meter”. Instructions stated that the threat meter levels displayed the current probability of losing money, when in fact loss only occurred when the level reached the maximum. Instructions also stated pressing an avoidance button lowered the threat level. Overall, instructions produced cycles of approach and avoidance responding with transitions from approach to avoidance when threat was high and transitions back to approach after avoidance reduced threat. Experiment 1 revealed increasing avoidance cost, but not threat magnitude, shifted approach–avoidance transitions to higher threat levels and increased anxiety ratings, but did not influence the frequency of approach–avoidance cycles. Experiment 2 revealed when threat level information was available or absent earnings were high, but earnings decreased when inaccurate threat information was incompatible with contingencies. Our findings build on prior nonhuman and human approach–avoidance research by highlighting how instructed threat and avoidance can impact human AA behavior and self‐reported anxiety.  相似文献

There is variability in the extent to which adolescents with attention-deficit/hyperactivity disorder (ADHD) exhibit social impairment, as the same diagnosis does not necessarily entail impairment in the same area(s) of functioning. The current study entailed a cross-sectional examination of enhancers to healthy social functioning and risk factors to parent- and self-rated social impairment in 324 middle school youth (ages 10–14 years) with ADHD. A series of binary logistic regression analyses were conducted to evaluate a risk-resilience model for social functioning, including testing compensatory (i.e., main; buffering) and protective (i.e., interaction) effects of enhancers in the presence of identified risk factors. Youth conduct problems, youth depression, and negative parenting emerged as risk factors. Self-rated social acceptance, activity participation (breadth and intensity), and parent involvement were enhancers of healthy social functioning. Of these enhancers, activity participation (breadth and intensity) and parent involvement showed buffering effects against the negative impact of the risk factors on social functioning. None of the enhancers displayed protective effects. The findings of this study enhance our understanding of the social functioning of young adolescents with ADHD, who comprise an understudied population relative to younger children with similar problems.  相似文献

The goal of this study was to use novel approaches that do not require the use of arbitrary cut-points (i.e., latent profile/transition analysis) to evaluate the prevalence and stability of the positive illusory bias (PIB) in young adolescents with attention-deficit/hyperactivity disorder (ADHD). Participants were 326 middle-school students diagnosed with ADHD (Mage = 12.26 years, 71% male, 77% Caucasian). The Self-Perception Profile for Children (SPPC) was completed by participants and their parents at baseline and again 12 and 18 months later. Cross-sectional results revealed four subgroups based on SPPC responses. Only a small subset (18.4%) of youth with ADHD exhibited a global PIB, across the behavioral, scholastic, and social domains, with an additional 29% displaying a PIB in the scholastic domain only. Additionally, average parent/adolescent-rated competence within each subgroup was in line with an objective measure of scholastic competence (i.e., grades). When examined longitudinally, only a PIB in the social domain was stable across the 18-month study period and only for half of the sample. These findings suggest that the PIB is not ubiquitous in youth with ADHD, with many young adolescents rating themselves accurately relative to their parents and their grades. Further, when stability across time is considered, the PIB may be specific to social functioning, as opposed to a global, cross-domain phenomenon. Implications for the future measurement of the PIB are discussed.  相似文献

Do references to God in political discourse increase confidence in the U.S. sociopolitical system? Using a system justification framework (Jost & Banaji, 1994 ), five studies provide evidence that, (1) increasingly governments symbolically associate the nation with God when public confidence in the social system may be threatened and (2) associating the nation with God serves a system‐justifying function by increasing public confidence in the system. In an analysis of U.S. presidential speeches, presidents were more likely to symbolically associate the nation with God during threatening times (Study 1). Among religious individuals, referencing God in political rhetoric increased the perceived trustworthiness of politicians, compared to patriotic secular rhetoric (Study 2) or simply priming the concept of God (Study 3). These effects were also unique to politicians from one's own sociopolitical system (Study 4). Finally, believing God has a plan for the United States attenuates the deleterious effect that perceptions of national decline have on system confidence (Study 5). Implications for the system‐justifying function of religion are discussed.  相似文献

To date, few studies have examined the social and psychological effects of sexting behaviors. The current study examined how delinquency, social, and psychological factors were associated with sexting behavior in a sample of rural, high school students (n = 548). The results demonstrated that property delinquency, bully-victimization, alcohol, marijuana use, and bullying increased odds of sending and receiving nude photos. Gender specific models indicated that females who had participated in sexting behavior were more likely to report using alcohol and being a victim of bullying, while males were more likely to report using marijuana and being a perpetrator of bullying. Implications are discussed.  相似文献

Rewarding top performers is of strategic importance to the sales organization. Top-performing salespeople not only contribute significantly to the success of their firm but may also motivate the skill development of peer salespeople. However, both academic research and anecdotal evidence suggest that top performer rewards can boomerang by damaging peer salespeople's morale and productivity, although the underlying mechanisms and boundary conditions remain unclear. Using a sample of salespeople and their managers from financial investment firms in Taiwan, the authors uncover both positive and negative effects of top-performer rewards. Specifically, it is found that when behavior control is employed, top-performer rewards are positively associated with perceived top-performer customer-relationship-building competence only when overall organizational justice is high. By contrast, when organizational justice is low and behavior control is employed, top-performer rewards give rise to perceived favoritism. Moreover, in large sales units, top-performer rewards are much less likely associated with perceived favoritism when organizational justice is high. It is through the perceived top-performer customer-relationship-building competence and perceived favoritism that top-performer rewards have a double-edged sword effect on fellow salespeople's selling skills, opportunism, and sales performance. Theoretical and managerial implications are discussed.  相似文献
