Procedural dependence in action memory: Effects of verb form and individual vs group conditions

Two experiments explored whether the magnitude of the enactment effect in action memory (i. e., higher recall with motor than with non-motor encoding) may depend upon the use of individual or group testing procedures. Nonmotor encoding instructions, requiring the subjects to listen to orally presented action items, were compared to instructions which also required enactment. With encoding treated as a within-subject factor, the observations failed to reveal any significant difference between individual and group testing. With encoding treated as a between-subject factor, the results showed an interaction between test and encoding conditions, such that an enactment effect was found only with group testing. Different support value for auditory cues in group and individual test situations was assumed to account for this difference. In a third experiment the indicative and imperative verb forms were compared. An interaction was observed, showing that in Norwegian, enacted verbs were remembered better when presented in the indicative than in the imperative. No corresponding difference was found under non-enactment conditions. For this finding, a social interaction interpretation was offered.     

汉字属性匹配与大脑两半球协同活动

在识别汉字时,大脑两半球同时加工的作业成绩是否随加工阶段的增加而显出优势。本研究用汉字形、音、义三种属性分别相匹配的方法用用指定指定提取法,所得实验结果一致表明,形似材料双侧视野同时识别与单侧视野识别成绩无显著差别,而同音与近义材料则表现出双侧呈现显著优于单侧呈现的作业成绩。最后结合脑功能成像研究,对加工阶段影脑半球佃同活动的原因进行了讨论。     

Intra‐active refractions

Responding to the analyses that Andreas Losch and Lucas John Mix offer regarding Living with Tiny Aliens: The Image of God for the Anthropocene, this article begins to address how their respective concerns regarding ratiocentric and anthropocentric ideas haunt the construction of a planetary account of the imago Dei. The article then introduces a subsequent line of critique not mentioned by Losch or Mix related to decentering the human individual from accounts of the imago Dei in order to highlight an ongoing challenge for transdisciplinary theological projects that involve astrobiology.     

动作视频游戏对发展性阅读障碍者阅读技能的影响及其内在机制

发展性阅读障碍是一种在获得阅读技能方面的特殊困难, 这种障碍会严重影响个体的发展, 如何帮助发展性阅读障碍者改善其阅读技能是近年来研究的焦点。传统的干预方法主要针对发展性阅读障碍者的语音缺陷, 这类方法存在一些问题, 如费时费力、给阅读障碍者带来阅读压力等。近年来, 大部分研究表明通过趣味性的动作视频游戏训练可以显著地提高发展性阅读障碍者的阅读技能, 但是其背后的机制尚不明确。基于大细胞通路缺陷理论框架, 从视觉空间注意、注意跨通道转换、视觉运动加工等方面来梳理动作视频游戏与阅读之间的关系, 揭示了动作视频游戏训练对阅读效率影响的可能内在机制。未来的研究可以在大细胞通路缺陷理论的框架下, 深入分析动作视频游戏改善阅读的神经机制, 并尝试开发更适合发展性阅读障碍者的干预程序。     

贝叶斯决策理论对复杂运动决策中运动预期的启发——以网球和足球为例

对运动决策的研究是认知运动心理学的一个重要领域。运动预期被认为是运动决策的核心, 受到运动学和非运动学信息的影响。其中, 对运动预期研究的一个关键问题是探讨不同信息源对运动结果预期的贡献以及两者之间的相互作用。研究者运用贝叶斯决策理论解释运动预期中不同信息的整合过程, 分析运动员在复杂的竞赛情景中如何做出最佳决策, 尤其是对该理论在网球和足球领域的潜在应用进行分析。在不确定的情况下, 竞技体育中并非所有的选择、结果或概率都是已知的, 故有研究者认为概率论和经典的决策理论不能有效解决此类问题。然而新近提出的启发式近似, 为运动员在贝叶斯框架下如何快速做出选择提供了理论依据：首先, 在复杂和有时间压力的竞赛情景中, 启发式近似假设运动员依据竞赛中不同信息源的不确定程度, 很可能选择在运动学信息和情境先验之间进行切换启发式, 提高运动预期的效率。其次, 判断效用通过卷积效应影响两种信息源的整合, 降低情境先验的影响程度。     

Internalized equality and protest against injustice: The role of disadvantaged group members’ self-respect in collective action tendencies

Recent research shows that self-respect (defined as seeing yourself as a person with equal rights) predicts assertive but not aggressive responses to injustice in interpersonal contexts. The present research focuses on the antecedents of self-respect and its consequences for collective action tendencies among members of disadvantaged groups. Across three studies (N = 227, N = 454, N = 131) using different contexts and samples (discrimination of Muslims in Germany; women regarding gender inequality), experiences with equality-based respect (defined as being treated as someone of equal worth) predicted self-respect. Moreover, across all three studies, self-respect predicted intentions for cooperative or normative but not support for hostile or non-normative protest. The results demonstrate the potential of self-respect for facilitating collective action in the face of injustice while still enabling positive intergroup relations.     

Standing up for whom? Targets’ different goals in the confrontation of discrimination

We challenge the common interpretation of targets’ immediate confrontation in reaction to discrimination as self-serving behavior and propose different underlying motivations for this phenomenon. In five online scenario studies (N_overall = 1,447), we demonstrate across different samples and contexts that targets indicate a distinct pursuit of the following self-reported confrontation goals: individual-benefit (e.g., perpetrator apologizes); group-benefit (e.g., prejudice reduction); and distancing (e.g., demonstrating that one is different from typical group members). Furthermore, meaningful associations of the pursuits of individual-benefitting goals and group-benefitting goals with group identification, disidentification, and further collective action intentions indicate that they represent different confrontation motivations: Individual-benefitting confrontation serves to cope with the individual mistreatment of discrimination, whereas group-benefitting confrontation represents a form of collective action. Distancing goals were associated with disidentification and—unexpectedly—group identification. Our results show that the phenomenon of confrontation in reaction to discrimination can be the result of different underlying psychological processes.     

Zero-sum beliefs shape advantaged allies’ support for collective action

Three studies (N₁ = 1,019; N₂ = 312; N₃ = 494) tested whether seeing intergroup relations as inherently antagonistic shaped advantaged social groups’ allyship intentions. More specifically, we tested whether endorsing zero-sum beliefs related to their willingness to support system-challenging and system-supporting collective action. Zero-sum beliefs were negatively correlated with system-challenging and positively correlated with system-supporting collective action intentions. Zero-sum beliefs were more common among advantaged than disadvantaged groups and translated into lower allyship intentions. Advantaged group members with higher levels of zero-sum beliefs were also more likely to experience anger and fear when considering the demographic racial shift in the United States. Increased fear was associated with greater support for system-supporting and lower support for system-challenging collective action. We find consistent evidence that advantaged group members see intergroup relations as a zero-sum game and that these beliefs are negatively related to their intentions to become allies.     

Making Americans Feel Great Again? Personal Significance Predicts Political Intentions of Losers and Winners of the 2016 U.S. Election

Reactions of losers and winners of political elections have important consequences for the political system during times of power transition. In four studies conducted immediately before and after the 2016 U.S. presidential elections, we investigated how personal significance induced by success or failure of one's candidate is related to hostile versus benevolent intentions toward political adversaries. We found that the less significant supporters of Hillary Clinton and supporters of Donald Trump felt after an imagined (Study 1A) or actual (Study 2) electoral failure the more they were willing to engage in peaceful actions against the elected president and the less they were willing to accept the results of the elections. However, while significance gain due to an imagined or actual electoral success was related to more benevolent intentions among Clinton supporters (Study 1B), it was related to more hostile intentions among Trump supporters (Studies 1B, 2, and 3).
