Judging a Book by its Cover: The Influence of Implicit Self‐Theories on Brand User Perceptions

Do people judge others based on the brands they use? Prior research finds evidence to this effect, yet we argue this phenomenon is far from universal. Drawing on research on implicit self‐theories, we find that only entity (but not incremental) theorists are prone to judging people based on their brand use (Studies 1 and 2). We show that entity theorists infer that people use brands to signal who they are to others, thereby forming perceptions of these people based on the personality of the brands they use, but incremental theorists are reluctant to make inferences about brand users’ signaling motives (Studies 3, 4, and 5). When tendencies to make signaling inferences are reduced, entity theorists no longer judge people based on their brand use (Studies 3 and 4). Furthermore, even incremental theorists judge people based on their brand use when given the information that their brand use is not driven by situational forces, but is potentially driven by a signaling motivation (Study 5).     

To buy or to sell: cultural differences in stock market decisions based on price trends

Four studies compared the stock market decisions of Canadians and Chinese. In two studies using simple stock market trends, compared with Chinese, Canadians were more willing to sell and less willing to buy falling stock. But when the stock price was rising, the opposite occurred: Canadians were more willing to buy and less willing to sell. A third study showed that for complex stock price trends, Canadians were strongly influenced by the most recent price trends: they tended to predict that recent trends would continue and made selling decisions without considering the rest of the trend patterns; whereas the Chinese made reversal predictions for the dominant trends and made decisions that took both recent and early trends into consideration. Study 4 replicated the finding with experienced individual investors. These findings are consistent with the previous literature on different lay theories of change held by Chinese and North Americans. Copyright © 2008 John Wiley & Sons, Ltd.     

身体锻炼对高中学生主观幸福感的影响及其心理机制

为了考察身体锻炼与高中学生主观幸福感的关系,采用量表法进行了研究,控制了相关变量后的研究结果表明:(1)经常锻炼的高中学生比锻炼不足的高中学生的主观幸福感更加强烈,这一差异表现在两者之间的情感成份和特殊生活满意感上;一次的身体锻炼对高中学生主观幸福感没有影响,长期性的身体锻炼可以提高高中学生主观幸福感;小锻炼量和中等锻炼量的身体锻炼随着锻炼持续时间的增长,对高中学生主观幸福感影响加深,而大锻炼量随着锻炼持续时间的增长对高中学生主观幸福感的影响,呈现倒“V”型的曲线状;随着锻炼持续时间的增长,中等锻炼量的效果明显优于小锻炼量和大锻炼量的效果;(2)身体锻炼不仅可以直接对高中学生主观幸福感产生影响,而且可以通过身体自尊,人际关系、人格等中介变量对高中学生主观幸福感产生影响     

心理咨询助人问题的探究

心理咨询在现代社会中,起着越来越大的作用,改善和提高了人们的心理健康水平,本文旨在加深对心理咨询含义的理解。首先对心理咨询的涵义做了探讨,进一步分析了心理咨询助人的含义,分别从心理咨询助人的基础,助人的方式,助人的目标做了阐释。最后探讨了咨询师的价值观与方法论对心理咨询可能产生的影响。心理咨询是心灵层面的沟通,通过体验关怀,达到来访者的心灵成长。咨询师对心理咨询的本质理解以及不同的咨询价值观和方法论都对心理咨询起着深远的影响。     

童年中期对抗行为的发展及其与同伴拒绝、同伴接纳的关系

采用教师报告法对1254名城市儿童的对抗行为发展进行追踪研究,并采用交叉滞后设计探讨了对抗行为与同伴拒绝/接纳间的关系.结果发现:(1)童年中期,对抗行为呈中等程度稳定性,并表现出随年龄下降的趋势;(2)男生的对抗行为水平显著高于女生;(3)交叉滞后分析发现,早期的同伴拒绝能显著正向预测后期的对抗行为,但早期同伴接纳不能预测后期的对抗行为;早期的对抗行为均能够显著预测后期的同伴拒绝以及同伴接纳.     

Perceived Parental Monitoring and Online Deviant Behavior Among Chinese Adolescents: a Moderated Mediation Model

Previous studies uncovered that perceived parental monitoring, personality, and self-control were three important external and internal factors that influenced adolescents’ online deviant behaviors. However, as the dark side of personality, the Dark triad, which implies a disagreeable disposition, lack of humility, belief of being able to predict future outcomes and an opportunistic life strategy, has rarely been used to explore its relationship with online deviant behaviors. Based on problem behavior theory, general aggression model, and models of risk factors and protective factors on problem/deviant behaviors, the current study investigated the relationship among perceived parental monitoring, the Dark Triad, and self-control on online deviant behaviors. A total of 1921 middle and high school students (aged 11–18 years) from China reported their online deviant behaviors (cyberbullying behavior, Internet rumors, deception on the Internet, and cyber obscenity/pornography), perceived parental monitoring, and the Dark Triad as well as the self-control level of individuals. The results of the Pearson correlation showed there were significant correlations among perceived parental monitoring, the Dark Triad, and self-control on online deviant behaviors. The results of the structural equation model (SEM) indicated that the Dark Triad partially mediated the relationship between perceived parental monitoring and online deviant behaviors. Self-control moderated the mediation effect of the Dark Triad. Specifically, self-control weakened the positive relationship between the Dark Triad and online deviant behaviors, and increased the negative relationship between perceived parental monitoring and online deviant behaviors. Our findings expand the applicable environment of the Dark Triad and emphasize its association with online deviant behaviors. Attention should be paid to the interaction of internal traits (e.g., personality and self-control) and explicit family environment (e.g., perceived parental monitoring) in online deviant behavior interventions.

“Plateau”-related summary statistics are uninformative for comparing working memory models

Performance on visual working memory tasks decreases as more items need to be remembered. Over the past decade, a debate has unfolded between proponents of slot models and slotless models of this phenomenon (Ma, Husain, Bays (Nature Neuroscience 17, 347-356, 2014). Zhang and Luck (Nature 453, (7192), 233-235, 2008) and Anderson, Vogel, and Awh (Attention, Perception, Psychophys 74, (5), 891-910, 2011) noticed that as more items need to be remembered, “memory noise” seems to first increase and then reach a “stable plateau.” They argued that three summary statistics characterizing this plateau are consistent with slot models, but not with slotless models. Here, we assess the validity of their methods. We generated synthetic data both from a leading slot model and from a recent slotless model and quantified model evidence using log Bayes factors. We found that the summary statistics provided at most 0.15 % of the expected model evidence in the raw data. In a model recovery analysis, a total of more than a million trials were required to achieve 99 % correct recovery when models were compared on the basis of summary statistics, whereas fewer than 1,000 trials were sufficient when raw data were used. Therefore, at realistic numbers of trials, plateau-related summary statistics are highly unreliable for model comparison. Applying the same analyses to subject data from Anderson et al. (Attention, Perception, Psychophys 74, (5), 891-910, 2011), we found that the evidence in the summary statistics was at most 0.12 % of the evidence in the raw data and far too weak to warrant any conclusions. The evidence in the raw data, in fact, strongly favored the slotless model. These findings call into question claims about working memory that are based on summary statistics.     

Effectiveness Evaluation of Search and Target Acquisition Training Prototype Using Performance Metrics With Eye-Tracking Data

Despite the increased use of sensor technologies, including unmanned vehicles, the vast majority of improvised explosive device (IED) detections are made by human vision. Thus, TRAC-Monterey developed a simulation-based training prototype called the perceptual learning trainer (PLT). Fourteen novice and 5 expert IED detectors participated in human-in-the-loop experiments in which all participants were trained using the PLT tool while their eye-movement and IED detection performance were tracked in real-time. A series of 100 IED images with various degrees of difficulty was used for the training session. Pre- and posttraining assessments were conducted. Both speed and accuracy improved after just 1 session of the PLT training: RT decreased by 3.7 s for novices (p < .001) and 3.4 s for experts (p = .031), and detection probability increased by 5.9% for novices (p = .001). The PLT tool improved IED detection performance more in novice IED detectors than in experts. Novices and experts showed different visual scan patterns.
