Parent–Child Similarity in Common and Specific Components of Prejudice: The Role of Ideological Attitudes and Political Discussion

Using a representative sample of Belgian adolescents (N = 1530) and both their parents, we investigated the parent–child similarity in prejudice towards different out‐groups and ideological attitudes (right‐wing authoritarianism and social dominance orientation). Contrary to previous studies, first, we distinguished between common and specific components of prejudice to test whether the parent–child similarity in one specific type of prejudice was symptomatic of parent–child similarity in prejudice towards out‐groups in general. Second, we evaluated whether the parent–child similarity in common and specific components of prejudice was related to the parent–child similarity in ideological attitudes. Third, we investigated the moderating role of political discussion in the intergenerational framework of ideology and prejudice. Results indicated that parent–child similarity was particularly pronounced for the common rather than the specific component of prejudice and that the similarity in ideological attitudes was partly related to the similarity in the common component of prejudice. Finally, adolescents who discuss social and political issues more (versus less) frequently with their parents more strongly resembled their parents in the common component of prejudice and levels of authoritarianism. These results suggest that generalized prejudice runs in families and highlight politicization of the family as an important socialization mechanism.

儿童依“相似性”分类能力的发展及影响分类结果因素的实验研究

以4-9岁儿童为被试,用6张主要是相同事物的多少有差异的刺激图片为实验材料,采用全部呈现刺激图片和逐——呈现刺激图片,并且利用有无目标图的方法,来探讨儿童依“相似性”分类能力的发展及影响分类结果的因素。结果表明:(1)随着年龄的增长,儿童依“相似性”分类的能力在提高。(2)按目标图分类方式的分类结果显著好于自由分类方式的分类结果。(3)逐一呈现刺激方式的分类成绩显著好于全部呈现刺激方式的分类成绩。     

客体相似性对不同认知方式个体视觉工作记忆表征的影响

采用整体检测的变化察觉范式,探讨客体的相似性对客体—空间型认知方式个体视觉工作记忆表征的影响。行为结果显示,在不相似客体的视觉工作记忆表征任务中,客体型者在长延时条件的成绩优于空间型者,而在相似客体的视觉工作记忆表征任务中,两者无差异;ERP结果显示,在不相似客体视觉工作记忆表征任务中,与客体型者相比,空间型者在大脑皮层诱发出更大的负SP。以上结果表明,客体型者比空间型者对不相似客体视觉工作记忆加工具有优势,其潜在机制可能在于,客体型者对不相似客体视觉工作记忆表征时的神经活动效能更高。     

Desired personality traits in politicians: Similar to me but more of a leader

What makes voters prefer a certain type of politician? First, we argue that voters’ trait preferences follow a “desired leadership” principle. We show that citizens want the ideal-type politician to be more emotionally stable, extravert-assertive, more deliberate-conscientious and open, more honest, but also somewhat more disagreeable than the average citizen. Second, we argue that voters prefer a model candidate with similar basic value-related personality traits. Importantly, we show that trait congruence is partly mediated by core ideological preferences and thus ensures democratic representation. The study’s findings have implications for personalization of politics and democratic representation, because personality traits can be vital cues for voters deciding whether candidates will act in their interest and represent them well.     

The effects of direction similarity in visual working memory: Behavioural and event-related potential studies

Object similarity can improve visual working memory (VWM) performance in the change-detection task, but impair the recognition performance when it occurs at retrieval of VWM in the recognition task. The effect of direction similarity is an issue that has not been well resolved. Furthermore, electrophysiological evidence in support of the mechanisms that underlie the effects of similarity is still scarce. In the current study, we conducted three behavioural experiments to examine the effects of direction similarity on memory performance with regard to both the encoding and retrieval phases of VWM and one event-related potential (ERP) experiment to explore the neural signatures of direction similarity in VWM. Our behavioural studies indicated that direction similarity improved performance when it occurred at the encoding phase but impaired performance when it occurred at the retrieval phase. Moreover, the ERP experiment showed that the amplitude of the contralateral delay activity (CDA) increased with the increasing set size for similar but not dissimilar directions. In addition, the CDA amplitude for similar directions was lower than that for dissimilar directions at set size 2. Taken together, these findings suggest that direction similarity at encoding has a positive effect on VWM performance and at retrieval has a negative effect. Given that VWM capacity depends on information load and the number of objects, the positive effect of similarity may be attributed to reduced information load of memory objects.     

Accuracy and assumed similarity in first impressions of personality: Differing associations at different levels of analysis

How are accuracy and assumed similarity associated in first impressions of personality? In a large-scale video perception study, accuracy and assumed similarity were strongly negatively associated across traits, consistent with past research (e.g., Beer & Watson, 2008). However, across perceivers and perceiver-target dyads, the ability to perceive others accurately was independent of the tendency to assume similarity with others. Thus, viewing others in general or specific others as overly similar to the self does not imply viewing them inaccurately. In sum, accuracy and assumed similarity are inversely related when examined across traits but are independent across perceivers and dyads.     

Mind-reading in strategic interaction: The impact of perceived similarity on projection and stereotyping

In social dilemmas, negotiations, and other forms of strategic interaction, mind-reading—intuiting another party’s preferences and intentions—has an important impact on an actor’s own behavior. In this paper, we present a model of how perceivers shift between social projection (using one’s own mental states to intuit a counterpart’s mental states) and stereotyping (using general assumptions about a group to intuit a counterpart’s mental states). Study 1 extends prior work on perceptual dilemmas in arms races, examining Americans’ perceptions of Chinese attitudes toward military escalation. Study 2 adapts a prisoner’s dilemma, pairing participants with outgroup targets. Study 3 employs an ultimatum game, asking male and female participants to make judgments about opposite sex partners. Study 4 manipulates perceived similarity as well as counterpart stereotype in a principal–agent context. Across the studies, we find evidence for our central prediction: higher levels of perceived similarity are associated with increased projection and reduced stereotyping.
