Can including pros and cons increase the helpfulness and persuasiveness of online reviews? The interactive effects of ratings and arguments

One guideline given to online reviewers is to acknowledge a product's pros and cons. Yet, I argue that presenting two sides is not always more helpful and can even be less persuasive than presenting one side. Specifically, the effects of two- versus one-sided arguments depend on the perceived consistency between a reviewer's arguments and rating. Across a content analysis and three experiments that vary the information provided in the online review and whether the ratings are positive or negative, the results support these predictions. Furthermore, beliefs that the reviewer is able (vs. willing) to tell the truth mediated the effects.     

Moral disengagement in self-reported and peer-nominated school bullying

This study examined the relation between moral disengagement and different self-reported and peer-nominated positions in school bullying. The aims of this study were to (1) investigate moral disengagement among children for whom self-reported and peer-nominated bully status diverged and (2) compare levels of disengagement among self-reported and peer-nominated pure bullies, pure victims, bully-victims, and children not involved in bullying. A sample of 739 Danish sixth grade and seventh grade children (mean age 12.6) was included in the study. Moral disengagement was measured using a Danish version of the Moral Disengagement Scale and bullying was measured using both self-reports and peer nominations. Results revealed that both self-reported and peer-nominated bullying were related to moral disengagement, and that both pure bullies and bully-victims displayed higher moral disengagement than outsiders. Discrepancies between self-reported and peer-nominated bullying involvement indicates that a person's social reputation has a stronger association with moral disengagement than so far expected. Implications are discussed, highlighting the importance of further research and theory development.     

Typical performance measures of emotion regulation and emotion perception and frontal EEG asymmetry in an emotional contagion paradigm

In order to replicate and extend previous observations of validity of the self-reported habitual regulation of one’s affect and the perception of other people’s emotions, prefrontal electroencephalographic (EEG) asymmetry was recorded during and after social-emotional stimulation. After stimulation with other people’s vocal expression of anxiety, individuals with lower scores on emotion regulation did not show recovery of asymmetry changes but even increased changes in the direction that had been adopted during the stimulation. Whether this was to the right or to the left depended on their scores on emotion perception. Participants high on perception showed the expected changes to the right during the anxiety stimulation (indicating increased withdrawal motivation) and to the left during the cheerfulness stimulation (indicating increased approach motivation), whereas individuals low on perception showed the opposite pattern. During the anxiety stimulation, participants low on perception only showed the unexpected change to the left if they were also low on regulation. Individual differences in regulation did not play a role when participants were confronted with other people’s laughter. The findings demonstrate the validity of the self-report measures by using EEG measures, and moreover support the usefulness of differentiated and process-oriented approaches in the field of trait emotional intelligence.     

青少年疏离感与病理性互联网使用的关系：家庭功能和同伴接纳的调节效应检验

通过对549名初一至高二年级城市青少年的问卷调查, 考察了青少年病理性互联网使用的特点及其与疏离感之间的关系, 并对家庭功能和同伴接纳是否可以调节疏离感与病理性互联网使用之间的关系进行了检验。结果发现：(1)在所有使用互联网的青少年被试中, 网络成瘾群体的检出率为8.93%; (2)女青少年病理性互联网使用的突显性水平高于男青少年。在病理性互联网使用的消极后果上, 初一青少年高于高一、初三和高二青少年。但青少年病理性互联网使用总体上不存在显著的性别和年级差异; (3)疏离感较高的青少年病理性互联网使用的水平也较高, 健康的家庭功能可以保护疏离感高的青少年减少病理性互联网使用, 但同伴接纳对高疏离感青少年减少病理性互联网使用不具有保护性作用。     

Developmental associations between externalizing behaviors, peer delinquency, drug use, perceived neighborhood crime, and violent behavior in urban communities

This study examines the precursors of violent behavior among urban, racial/ethnic minority adults. Data are from an on-going study of male and female African Americans and Puerto Ricans, interviewed at four time waves, Time 1-Time 4 (T1-T4), from adolescence to adulthood. Structural Equation Modeling was used to analyze the developmental pathways, beginning in mid-adolescence (T1; age = 14.0 years), to violent behavior in adulthood (T4; age = 29.2 years). The variables assessed were: components of externalizing behaviors (i.e., rebelliousness, delinquency; T1, T3); illicit drug use (T2); peer delinquency (T2); perceived neighborhood crime (T4); and violent behavior (T3, T4). Results showed that the participants' externalizing behaviors (rebelliousness and delinquency) were relatively stable from mid-adolescence (T1; age = 14.0 years) to early adulthood (T3; age = 24.4 years). The participants' externalizing behaviors in mid-adolescence also had a direct pathway to peer delinquency in late adolescence (T2; age = 19.1 years). Peer delinquency, in turn, had a direct pathway to the participants' illicit drug use in late adolescence (T2), and to externalizing behaviors in early adulthood (T3). The participants' illicit drug use (T2; age = 19.1 years) had both direct and indirect paths to violent behavior in adulthood (T4). The participants' externalizing behaviors in early adulthood (T3) were linked with violent behavior at T3, and perceived neighborhood crime (T4), both of which had direct pathways to violent behavior in adulthood (T4). The findings suggest developmental periods during which externalizing behaviors, exposure to delinquent peers, illegal drug use, and neighborhood crime could be targeted by prevention and intervention programs in order to reduce violent behavior.     

Distant Peers

What is the nature of rational disagreement? A number of philosophers have recently addressed this question by examining how we should respond to epistemic conflict with a so‐called epistemic peer—that is, someone over whom you enjoy no epistemic advantage. Some say that you're rationally required to suspend judgment in these cases—thereby denying the very possibility of a certain kind of rational disagreement. Others say that it's permissible to retain your beliefs even in the face of epistemic conflict. By distinguishing between close peers and distant peers, I argue that it's rational to respond to different types of peers in different ways. I also argue that remote peers—a particularly distant kind of distant peer—provide us with an important lesson in epistemic humility.     

Physical and Relational Aggression in Early Adolescence: Associations with Narcissism,Temperament, and Social Goals

This study examined adolescent narcissism, temperament (frustration and affiliation), and social goals in association with peer‐reported physical and relational aggression (N = 384; 12–14 years). Narcissism was positively associated with dominance goals and negatively with closeness goals for peer interaction. Moreover, narcissism was positively associated with physical aggression via dominance goals for boys, and with relational aggression via dominance goals for both genders. Temperamental frustration and affiliation were both positively associated with relational aggression, but also interacted in their associations with this variable; affiliation was positively associated with relational aggression only at high levels of frustration. Supporting and extending existing research, the present findings suggest that adolescent personality and social goals are meaningfully associated with physical and relational aggression in the peer context.     

Do equilibrium constraints modulate postural reaction when viewing imbalance?

Action observation and action execution are tightly coupled on a neurophysiological and a behavioral level, such that visually perceiving an action can contaminate simultaneous and subsequent action execution. More specifically, observing a model in postural disequilibrium was shown to induce an increase in observers' body sway. Here we reciprocally questioned the role of observers' motor system in the contagion process by comparing participants' body sway when watching displays of antero-posterior vs. lateral imbalance. Indeed, during upright standing, biomechanical constraints differ along the antero-posterior (A-P) and medio-lateral (M-L) axes; hence an impact of observers' postural constraints on the contagion response would result in different reactions to both types of stimuli. In response to the displays, we recorded greater area of center of pressure (CoP) displacement when watching forward/backward compared to left/right imbalance. In addition, after normalizing A-P and M-L CoP displacements by a control condition (fixation cross), A-P CoP path length when viewing forward imbalance tended to be higher than M-L CoP path length when viewing imbalance to the left or right. These results indicate that postural contagion is promoted when the display is compatible with observers' motor stabilization strategy which is mainly oriented along the A-P axis. In terms of clinical application, this study brings new indications for adaptation of observational training devices in rehabilitation programs.     

Modern Regression Methods that can Substantially Increase Power and Provide a more Accurate Understanding of Associations

During the last half century, hundreds of papers published in statistical journals have documented general conditions where reliance on least squares regression and Pearson's correlation can result in missing even strong associations between variables. Moreover, highly misleading conclusions can be made, even when the sample size is large. There are, in fact, several fundamental concerns related to non‐normality, outliers, heteroscedasticity, and curvature that can result in missing a strong association. Simultaneously, a vast array of new methods has been derived for effectively dealing with these concerns. The paper (i) reviews why least squares regression and classic inferential methods can fail, (ii) provides an overview of the many modern strategies for dealing with known problems, including some recent advances, and (iii) illustrates that modern robust methods can make a practical difference in our understanding of data. Included are some general recommendations regarding how modern methods might be used. Copyright © 2011 John Wiley & Sons, Ltd.     

Perceived physical competence and body image as predictors of perceived peer acceptance in adolescents

The purpose of this study was to investigate the relationships among perceived physical competence, body image, and peer acceptance. Body image was considered as a possible mediator of the relationships between perceived physical competence and peer acceptance. Adolescents (N = 838) completed questionnaires. Direct and indirect effects of perceived physical competence and body image on perceived peer acceptance were explored using structural equation modelling. Gender differences were found and the structural mediation model was a reasonable fit to the data; the pattern of relationships in the model was different for adolescent males and females.
