自强还是自嘲?名人代言如何提升社会化媒体广告的营销效果

企业为了促进产品推广, 不惜重金聘请名人为产品代言。已有的文献主要探究名人代言的自强型模式, 很少研究名人代言的自嘲型的表达方式。本文则基于社会影响理论和产品差异理论探究了两种类型名人代言在不同产品情境下对消费者口碑推荐的影响。通过二手数据分析和实验法研究发现：自强型的名人代言更有利于提升消费者对享乐型产品的口碑推荐; 自嘲型的名人代言更有利于提升消费者对实用型产品的口碑推荐; 自强型的名人代言主要是通过强化其规范性影响, 进而增强消费者对享乐型产品的口碑推荐; 自嘲型的名人代言主要是通过强化其信息性影响, 进而增强消费者对实用型产品的口碑推荐。     

The effects of social influence on children's memory reports: the omission and commission error asymmetry

Children in two age groups (7 vs. 12 yrs, N= 174) individually interacted with a stranger and were later interviewed about this event. Right before the interview, each child encountered the stranger once again and he engaged in a conversation where he either suggested that a (central or peripheral) detail originally present in the event had actually not been there or that an originally non-present (central or peripheral) detail had in fact been there. It was hypothesized that the two types of misinformation would result in omission and commission errors respectively. The results showed that the social influence resulted in an asymmetric effect (i.e., more commission than omission errors). Importantly, we also found that the children made more errors with respect to the peripheral detail (a suitcase), compared to the central detail (a passenger). Younger children did not make more errors (neither omission nor commission errors) than older children.     

Chinese working in groups: Effort dispensability versus normative influence

Chinese participants were found less likely to social loaf when working in groups than did North Americans. This result was attributed mainly to the collectivism and individualism characterizing Chinese and North Americans, respectively. However, this explanation does not address how Chinese people's social loafing tendency may vary across situations. If Chinese participants are concerned about their relations with coworkers, they should be more likely to conform to the performance level of their coworkers. This prediction is in opposition to effort dispensability, which is usually found among North Americans, whereby individuals adjust their effort in reverse to that of their coworkers. Consistent with our prediction, findings from three studies revealed that Chinese participants tended to conform to the performance level of their coworkers when their performance is made public ( vs kept anonymous) and when they have high ( vs low) relational concerns. These findings have implications for unpacking nuanced cultural influences on behaviours.     

Taxicab Correspondence Analysis

Taxicab correspondence analysis is based on the taxicab singular value decomposition of a contingency table, and it shares some similar properties with correspondence analysis. It is more robust than the ordinary correspondence analysis, because it gives uniform weights to all the points. The visual map constructed by taxicab correspondence analysis has a larger sweep and clearer perspective than the map obtained by correspondence analysis. Two examples are provided. This research was financed by the Natural Sciences and Engineering Research Council of Canada. The author thanks Serge Vienneau for his help regarding the graphical displays, and also thanks the editor, associate editor, and two reviewers for their constructive comments.

Collective estimation: Accuracy,expertise, and extroversion as sources of intra-group influence

Although estimations typically possess correct answers, these answers may be difficult to demonstrate to others. However, providing external information may increase their demonstrability. In this experiment, individuals (N = 60) and 6-person groups (N = 360) generated estimations with or without frames of reference. We hypothesized that estimations involving frames of reference would be best fit by models predicting intra-group influence based on the accuracy of alternatives or of members in general. Conversely, we hypothesized that estimations not involving frames of reference would be best fit by models predicting influence based on member extroversion or proposal centrality. Results indicate that groups outperformed individuals and that estimations generated in the presence of frames of reference were superior to those generated in their absence. Accuracy and expertise schemes provided the best fit when frames of reference were provided, whereas an extroversion scheme provided the best fit when they were not.     

Recurrent binge eating with and without the "undue influence of weight or shape on self-evaluation": implications for the diagnosis of binge eating disorder

Levels of eating disorder psychopathology, impairment in psycho-social functioning and use of health services were compared among probable cases of binge eating disorder (BED) with and without extreme weight or shape concerns ("undue influence of weight or shape on self-evaluation") recruited from a large community sample of women. Data for obese non-binge eaters (n=457), also recruited from the community sample, and for a clinical sample of eating disorder patients (n=128), recruited separately, were included for comparative purposes. BED cases who reported extreme weight or shape concerns (n=51, 46.4%) had significantly higher levels of eating disorder psychopathology and functional impairment than those who did not report such concerns (n=59), after controlling for between-group differences in age and body weight. In addition, BED cases who reported extreme weight or shape concerns were more likely to have sought treatment for an eating or weight problem than those who did not. Whereas levels of eating disorder psychopathology and functional impairment were markedly elevated among BED cases with extreme weight or shape concerns, BED cases who did not report extreme weight or shape concerns resembled obese non-binge eaters in most respects. The findings support the inclusion of an undue influence of weight or shape on self-evaluation as a diagnostic criterion for BED. In the absence of this influence, eating disorders that otherwise resemble BED do not appear to be "clinically significant".

Does Watching Smoking in Movies Promote Teenage Smoking?

ABSTRACT— Compared to adolescents with low exposure to smoking in movies, those with high exposure are about three times as likely to try smoking or become smokers. We have observed this effect in nationally representative samples using cross-sectional and longitudinal designs. This effect remains statistically significant after controlling for numerous other traditional risk factors, such as personality, parenting style, and sociodemographics. Indeed, the movie-smoking exposure effect on adolescent smoking initiation is greatest among those traditionally considered at lower risk for smoking, such as those low in sensation seeking and those whose parents do not smoke. In this article, we consider possible moderators and mediators of this important media effect as well as health-policy implications. The take-home message is that eliminating smoking in movies may prevent a substantial number of adolescents from smoking.
