When the “Charm of Three” Fades: Mental Imagery Moderates the Impact of the Number of Ad Claims on Persuasion

Given the prevalence of imagery appeals in today’s marketplace, the current research studies the role of mental imagery in how consumers process and react to advertisements with different numbers of ad claims. Past research has proposed “three” as the magical number of ad claims that maximizes persuasion, with more than three ad claims increasing skepticism and reducing evaluation. In the current research, we replicate this so-called “charm of three” effect, but only when consumers do not engage in mental imagery; when they do, however, we find that the effect is moderated, in that more ad claims beyond three produces more favorable product evaluation. Additionally, we provide evidence that the moderating effect of mental imagery is driven by transportation and skepticism toward the ad claims, with mental imagery increasing transportation and decreasing skepticism when there are more than three ad claims. Our research contributes to a better understanding of the “charm of three” effect, its boundary conditions, and underlying mechanism.     

歧视知觉对初中生的合作倾向与行为的影响

本文通过两个研究揭示歧视知觉对初中生合作倾向与行为的影响, 研究1采用问卷法对752名初中生进行为期一年的追踪, 运用潜变量交叉滞后结构方程模型分析歧视知觉与合作倾向之间的纵向预测关系; 研究2采用动态公共物品困境实验考察歧视知觉对合作行为的影响, 以及群体类型的调节作用。结果发现：(1)初中生的歧视知觉与合作倾向存在显著负相关; T1合作倾向可负向预测T2歧视知觉, T2歧视知觉可负向预测T3合作倾向; (2)在公共物品困境前三轮投资比和贡献率上, 歧视知觉和群体类型的交互效应显著; 而在后三轮仅发现歧视知觉在投资比和贡献率上的主效应, 以及群体类型在贡献率上的主效应。以上结果表明, 歧视知觉与合作倾向之间存在纵向螺旋式影响; 歧视知觉对前期合作行为的影响受到群体类型的调节, 但随着互动时间延长, 该调节作用消失。

Intrapersonal and Interpersonal Sources of Resilience: Mechanisms of the Relationship Between Bullying Victimization and Mental Health Among Migrant Children in China

Compared with their non-migrant peers, migrant children in China face major risks and challenges that may cause them to develop behavioral and psychological problems. Nevertheless, research has seldom addressed their victimization by bullies and its association with their mental health outcomes, much less the roles of intrapersonal and interpersonal sources of resilience in that relationship. In response, this study was designed to examine how bullying victimization both directly and indirectly influences migrant children’s mental health through intrapersonal and interpersonal sources of resilience. Data were collected from a school-based multistage random sample of 1,132 migrant children in Grades 4–9 (mean age = 11.88 years, range = 8–17 years; boys = 55.6%) attending public schools in Nanjing and private schools in Guangzhou, China. Structural equation modeling performed with Amos 25.0 revealed that both intrapersonal and interpersonal sources of resilience mediated the effect of bullying victimization on migrant children’s mental health, albeit intrapersonal sources demonstrated a slightly stronger mediation effect. The results thus suggest that social workers and educators should provide effective prevention and intervention strategies that promote intrapersonal and interpersonal sources of resilience among migrant children in China.

     

A robust vision-based method for staircase detection and localization

A robust vision-based staircase identification method is proposed, which comprises 2D staircase detection and 3D staircase localization. The 2D detector pre-screens the input image, and the 3D localization algorithm continues the task of retrieving geometry of the staircase on the reported region in the image. A novel set of principal component analysis-based Haar-like features are introduced, which extends the classical Haar-like features from local to global domain and are extremely efficient at rejecting non-object regions for the early stages of the cascade, and the Viola–Jones rapid object detection framework is improved to adapt the context of staircase detection, modifications have been made on the scanning scheme, multiple detections integrating scheme and the final detection evaluation metrics. The V-disparity concept is applied to detect the planar regions on the staircase surface and locate 3D planes quickly from disparity maps, and then, the 3D position of staircase is localized robustly. Finally, experiments show the performance of the proposed method.     

抑郁个体对情绪面孔的返回抑制能力不足

探讨抑郁对情绪面孔返回抑制能力的影响。以贝克抑郁量表、自评抑郁量表、CCMD-3和汉密顿抑郁量表为工具筛选出了正常对照组、抑郁康复组和抑郁患者组各17名被试进行了真人情绪面孔线索-靶子任务的行为学实验和事件相关电位(ERP)实验。在线索靶子范式中, 靶子在线索消失后出现, 被试对靶子的位置作出反应。行为学实验显示线索靶子间隔时间(stimulus onset asynchronies, SOA)为14ms时, 正常对照组对中性面孔有返回抑制效应, 抑郁康复组对所有面孔均存在返回抑制效应, 患者组对愤怒、悲伤面孔和中性面孔存在返回抑制效应; SOA为250ms时三组被试均对悲伤面孔存在返回抑制能力不足, 以患者组最突出, 康复组对高兴面孔存在返回抑制能力不足; SOA为750ms时正常组对悲伤面孔存在返回抑制效应, 康复组对高兴和悲伤面孔存在返回抑制能力不足, 患者组对悲伤面孔存在返回抑制能力不足, 对愤怒面孔存在返回抑制效应。在SOA为750ms的条件下, ERP波形特点为正常组对高兴面孔线索P3波幅大于其他组, 对高兴面孔无效提示P1波幅小于其他面孔, 对悲伤面孔有效提示P1波幅小于高兴面孔, 对高兴面孔有效提示P3波幅大于患者组, 对悲伤面孔无效提示P3波幅大于其他组; 康复组对悲伤面孔线索P3波幅大于其他面孔, 对高兴面孔有效提示P3波幅大于患者组, 对悲伤面孔无效提示P3波幅小于正常组; 患者组对悲伤面孔线索P1波幅大于其他组、P3波幅大于其他面孔, 对悲伤面孔无效提示P3波幅小于正常组, 高兴面孔有效提示P3波幅小于其他组。提示抑郁患者对负性刺激有返回抑制能力不足, 这种对负性刺激抑制能力的缺失导致抑郁个体难以抗拒负性事件的干扰而受到不良情绪状态的困扰, 所以他们可能更多的体验到抑郁情绪, 并致使抑郁持续和发展。而抑郁康复个体对高兴、悲伤面孔均有返回抑制能力不足, 这让康复个体能同时感受到正、负性刺激, 从而能保持一种认知和情绪上特定的平衡。

Longitudinal Associations between Oppositional Defiant Symptoms and Interpersonal Relationships among Chinese Children

Children with oppositional defiant disorder (ODD) are at increased risk for developing poor relationships with people around them, but the longitudinal links between ODD symptoms and subsequent interpersonal functioning remain unclear. In the current study, we examined the bidirectional associations between ODD symptoms and children’s relationships with parents, peers, and teachers. We included separate analyses for parent vs. teacher reports of ODD symptoms, with regard to subsequent interpersonal relationships. Participants included 256 children with ODD, recruited in China, along with their parents and teachers, assessed at three time points roughly two years apart. Parents and teachers reported child ODD symptoms at each time point, and children reported their perceptions of father– and mother–child attachment, peer relationships, and teacher–student relationships across the three time points. ODD symptoms reported either by parents or teachers predicted impairments in interpersonal functioning. Meanwhile, child interpersonal impairments with peers and teachers predicted subsequent increase in teacher-reported ODD symptoms. These findings highlight the importance of transactional models of influence—and of considering early intervention for ODD in protecting children from developing further deficits and impairments. Additionally, we discuss the perspectives of multiple informants on ODD symptoms, including their different patterns of association with subsequent interpersonal relationships.     

Perceived Perfectionism from God Scale: Development and Initial Evidence

In this study, the Perceived Perfectionism from God Scale (PPGS) was developed with Latter-day Saints (Mormons) across two samples. Sample 1 (N = 421) was used for EFA to select items for the Perceived Standards from God (5 items) and the Perceived Discrepancy from God (5 items) subscales. Sample 2 (N = 420) was used for CFA and cross-validated the 2-factor oblique model as well as a bifactor model. Perceived Standards from God scores had Cronbach alphas ranging from .73 to .78, and Perceived Discrepancy from God scores had Cronbach alphas ranging from .82 to .84. Standards from God scores were positively correlated with positive affect, whereas Discrepancy from God scores was positively correlated with negative affect, shame and guilt. Moreover, these two PPGS subscale scores added significant incremental variances in predicting associated variables over and above corresponding personal perfectionism scores.     

Are Decisions Made by Group Representatives More Risk Averse? The Effect of Sense of Responsibility

We tested the hypothesis that a sense of responsibility drives group representatives' decisions to be more risk averse compared with decisions made by individuals. The hypothesis was supported when the monetary considerations (i.e., payoff inequality and the magnitude effect) were controlled for in the potential gain domain as well as in the potential loss domain. Evidence showed that this is because the group representatives were concerned about how they would view themselves (e.g., guilt and self‐blame) and also how they would be viewed by others (i.e., to avoid being blamed and looked down upon by others). This study provided new insights into understanding group representatives' decision making under risk. Copyright © 2017 John Wiley & Sons, Ltd.
