Janus‐faced nature of colorblindness: Social dominance orientation moderates the relationship between colorblindness and outgroup attitudes

Colorblindness is a popular diversity ideology promoted as a means to intergroup harmony in ethnically diverse nations. While some research suggests that colorblindness reduces intergroup bias, other work suggests that colorblindness may increase it. The present research utilizes a national sample of European New Zealanders to examine whether the relationship between colorblind endorsement and outgroup attitudes is moderated by perceivers' individual differences in social dominance orientation (SDO). Data revealed that for participants low in SDO, colorblind beliefs predicted more negative attitudes toward ethnic minorities. However, for those high in SDO, colorblind beliefs predicted more positive attitudes toward ethnic minorities. Taken together, these findings suggest that colorblindness is not all good or bad for intergroup relations—instead, its effects may depend on perceivers' own egalitarian sentiments.     

集中和分散注意对多感觉整合中听觉主导效应的影响

听觉主导效应是指多感觉通道信息整合过程中,听觉通道中的信息得到优先加工,从而主导其他感觉通道的信息。研究采用经典的声音诱发闪光错觉的范式,通过两个实验操纵了注意资源的分配方式以及实验任务难度,考察了主动注意听觉通道的声音刺激对声音诱发闪光错觉产生的影响,以及任务难度对声音诱发闪光错觉的影响。结果发现:(1)裂变错觉会受到注意资源分配程度的影响,但是融合错觉则不然;(2)任务难度既不会影响裂变错觉,也不会影响融合错觉。说明了分散注意能够影响听觉主导效应中的裂变错觉,并且这种主导效应与任务难度无关。     

Nonverbal zero-acquaintance accuracy of self-esteem,social dominance orientation,and satisfaction with life

Two samples of undergraduates judged the personalities of strangers (either six men or six women) after viewing a 30 s, silent video clip of each target. We evaluated the accuracy of five traits, three of which were not previously studied in zero-acquaintance research (self-esteem, social dominance orientation (SDO), and satisfaction with life (SWL); we also tested masculinity and femininity). We compared these five new traits to a baseline of accuracy for extroversion. People reached consensus on self-esteem, SDO, and SWL, though accuracy was higher and more consistent for male targets. Significant self-other agreement was obtained only for SWL, for male targets. We replicated past studies by demonstrating zero-acquaintance accuracy for masculinity but not femininity.     

The Relationship between Social Dominance Orientation and Gender: The Mediating Role of Social Values

Invariance hypothesis posits that, across cultures and contexts, men are higher in SDO than women. Social Dominance Theory (SDT) suggests that this difference is biologically determined and resulting from the differences in reproductive strategies between sexes. In this study we tested the hypothesis that values can explain gender–SDO differences. SDT suggests that SDO mediates gender differences in values. The contrasting hypothesis suggests that gender–SDO differences are mediated by values. Using SEM with a sample of Italian University students (N = 162, 80 men), the results provided strong support for the hypothesis of a mediation effect of values. Indeed, when controlling for values, gender difference in SDO disappear. Very similar findings were obtained for both GBD and OEQ. Results are discussed.     

确定、不确定及风险状态下选择反转:“齐当别”选择方式的解释

应用广义“弱优势”（weak dominance）模型检验确定、不确定及风险状态下的选择反转现象。该模型将人们的二择一选择行为描述为一种搜寻一备择方案在主观上优越于另一备择方案的过程。即：在甲方案在某一维度上优越于乙方案,而乙方案在另一维度上优越于甲方案的情况下,为了利用“弱优势”（weak dominance）原则达成决策,人们必须在一维度上将两者间较小的差异人为地“齐同”掉,而在另一维度上将“辨别”两者间较大的差异作为最终选择的依据。因此,在每次选择时,如果不认为最大的差异都是来自同一维度,就会导致选择反转。此项研究设计了一“匹配”任务,并借此检验,在不同的决策状态下,判断两备择方案在各维度上的差异是否能预测人们的重复选择变异。总的测试-再测试结果支持“齐当别”选择方式的解释。其发现表明：重复选择之所以可能是一致的,并不是因为每次都认定被选中的备择方案具有最大值,而是因为每次选择都认定最大的差异来自一固定的维度。     

Less is better: when low-value options are valued more highly than high-value options

This research demonstrates a less-is-better effect in three contexts: (1) a person giving a $45 scarf as a gift was perceived to be more generous than one giving a $55 coat; (2) an overfilled ice cream serving with 7 oz of ice cream was valued more than an underfilled serving with 8 oz of ice cream; (3) a dinnerware set with 24 intact pieces was judged more favourably than one with 31 intact pieces (including the same 24) plus a few broken ones. This less-is-better effect occurred only when the options were evaluated separately, and reversed itself when the options were juxtaposed. These results are explained in terms of the evaluability hypothesis, which states that separate evaluations of objects are often influenced by attributes which are easy to evaluate rather than by those which are important. © 1998 John Wiley & Sons, Ltd.     

Dominance structure in small groups of juvenile white-seabream (Diplodus sargus cadenati de la paz,Bauchot and Daget 1974)

Experiments were conducted to investigate the intraspecific aggressive interactions between juveniles of white-seabream (Diplodus sargus cadenati de la Paz, Bauchot and Daget 1974) in relation to dominance hierarchy in small groups. The agonistic interactions between juvenile white-seabream in small groups originated a peck-dominance hierarchy. The dominant (α-fish) generally interacted aggressively and most frequently with the subordinate that was next in line (β-fish) within the dominance hierarchy. This β-fish interacted aggressively more frequently with the γ-fish, and so on. Results demonstrated that fish do not attack subordinates at random. The level of subordination in small groups of juvenile white-seabream was related to body size. Generally, the more aggressive fish manifest a higher growth rate. Aggr.

“Escape from Freedom”: Authoritarianism-related traits,political ideology,personality, and belief in free will/determinism

Philosophers have long speculated that authoritarianism and belief in determinism are functionally related. To evaluate this hypothesis, we assessed whether authoritarianism and allied personality and political variables predict varieties of belief in determinism in three community samples (N₁ = 566 to 20,010; N₂ = 500; N₃ = 419). Authoritarianism and allied variables manifested moderate to large positive correlations with both fatalistic and genetic determinism beliefs. Controlling for political conservatism did not meaningfully attenuate these relations. Further, openness was negatively related to fatalistic determinism beliefs and agreeableness was negatively related to genetic determinism beliefs. Taken together, our findings clarify the nature of relations between authoritarianism and general personality, on the one hand, and free will/determinism beliefs, on the other, and suggest intriguing intersections between worldviews and personality traits.     

Dominance-subordinance in cohabiting pairs of adult rats: Effects on Aggressive behavior

Following an initial intruder aggression test, 10 pairs of adult male rats matched on aggressiveness were formed. The first 20 min of paired cohabitation were used to determine dominance and subordinance between pau members. Residents judged to be dominant from this observation session gained significantly more weight during cohabitation and exhibited significantly more aggression on the second aggression test than their subordinate counterparts. Significant correlations among various measures of aggression were found, but open field performance did not correlate, with the measures of aggression nor did changes in open field scores reflect changes in aggression.
