Making Probabilistic Relational Categories Learnable

Theories of relational concept acquisition (e.g., schema induction) based on structured intersection discovery predict that relational concepts with a probabilistic (i.e., family resemblance) structure ought to be extremely difficult to learn. We report four experiments testing this prediction by investigating conditions hypothesized to facilitate the learning of such categories. Experiment 1 showed that changing the task from a category‐learning task to choosing the “winning” object in each stimulus greatly facilitated participants' ability to learn probabilistic relational categories. Experiments 2 and 3 further investigated the mechanisms underlying this “who's winning” effect. Experiment 4 replicated and generalized the “who's winning” effect with more natural stimuli. Together, our findings suggest that people learn relational concepts by a process of intersection discovery akin to schema induction, and that any task that encourages people to discover a higher order relation that remains invariant over members of a category will facilitate the learning of putatively probabilistic relational concepts.     

左右半球在语篇理解中的协同作用

通过2例一侧颞叶损伤患者研究了一侧颞叶损伤及两侧半球的协同作用对语篇理解的影响,并探讨了发生此种影响的可能机制。结果表明一侧颞叶的损伤将导致患者语篇水平的理解障碍及语言推理能力的下降;提示语篇理解需双侧半球的协同作用,而推理能力下降可能是引发语篇理解障碍的原因之一。     

Reaching Across the DMZ: Identity Uncertainty and Reunification on the Korean Peninsula

Drawing on uncertainty‐identity theory (Hogg, 2012), we explore the effects of uncertainty concerning a specific social identity on group identification and attitudes toward subgroup integration and separation in South Koreans' nested identity context (N = 148). All variables were measured. Path analysis revealed, as predicted, that superordinate identity uncertainty weakened superordinate identification and subgroup identity uncertainty weakened subgroup identification. We also found that subgroup identity uncertainty strengthened superordinate identification. This effect was stronger for those who perceived their superordinate group prototype and subgroup prototype to be distinct and nonoverlapping. Furthermore, superordinate identity uncertainty decreased reunification intentions by weakening superordinate identification. Subgroup identity uncertainty increased reunification intentions by strengthening superordinate identification only for those who perceived their superordinate group prototype and subgroup prototype to be distinct and nonoverlapping. Implications for uncertainty identity theory and intergroup relations are discussed.     

双眼深度感知与图像元素数量的关系

用微机化的伪随机点立体图对发生器产生静态和动态随机点立体图对(RDS),显示在左右两个示波器上。RDS图形中的元素密度可以改变。具有正常立体视的10名被试通过立体镜观察这些图形,测量双眼融合能产生完整立体图形感知所需最小的元素密度,即密度容限。 设计了三个实验用以检测改变RDS图形的空间参数对密度客限的影响。第一个实验,在静、动态RDS图形下,改变视差图形面积;第二个实验,改变视差图形的形状;第三个实验,改变视差图形的周长。 实验结果表明,双眼深度感知要求一定的元素密度容限,视差图形的大小和形状对密度容限有一定程度的影响。静态和动态RDS图形的密度容限也不相同。 本文利用RDS的整体立体感知特性和空间频率通道理论对实验结果进行了讨论。     

古代和谐思想与构建社会主义和谐社会

和谐是中国传统文化的核心理念,中国古代和谐思想内容广泛,包含着人与自身、人与人、人与自然之间的和谐,也就是内心和谐、社会和谐、宇宙和谐.这一宝贵思想在今天仍具有重要的理论意义和实践意义.构建社会主义和谐社会必须统筹协调各方面伦理关系,妥善处理社会矛盾,以达到内心和谐、社会和谐、人与自然和谐.     

Diversity is what you want it to be: how social-dominance motives affect construals of diversity

We propose that diversity is a malleable concept capable of being used either to attenuate or to enhance racial inequality. The research reported here suggests that when people are exposed to ambiguous information concerning an organization's diversity, they construe diversity in a manner consistent with their social-dominance motives. Specifically, anti-egalitarian individuals broaden their construal of diversity to include nonracial (i.e., occupational) heterogeneity when an organization's racial heterogeneity is low. By contrast, egalitarian individuals broaden their construal of diversity to include nonracial heterogeneity when an organization's racial heterogeneity is high. The inclusion of occupational heterogeneity in perceptions of diversity allows people across the spectrum of social-dominance orientation to justify their support for or opposition to hierarchy-attenuating affirmative-action policies. Our findings suggest that diversity may not have a fixed meaning and that, without a specific delineation of what the concept means in particular contexts, people may construe diversity in a manner consistent with their social motivations.     

Cuing consumerism: situational materialism undermines personal and social well-being

Correlational evidence indicates that materialistic individuals experience relatively low levels of well-being. Across four experiments, we found that situational cuing can also trigger materialistic mind-sets, with similarly negative personal and social consequences. Merely viewing desirable consumer goods resulted in increases in materialistic concerns and led to heightened negative affect and reduced social involvement (Experiment 1). Framing a computer task as a "Consumer Reaction Study" led to a stronger automatic bias toward values reflecting self-enhancement, compared with framing the same task as a "Citizen Reaction Study" (Experiment 2). Consumer cues also increased competitiveness (Experiment 3) and selfishness in a water-conservation dilemma (Experiment 4). Thus, the costs of materialism are not localized only in particularly materialistic people, but can also be found in individuals who happen to be exposed to environmental cues that activate consumerism-cues that are commonplace in contemporary society.     

Differences in Beliefs About Psychological Services in the Relationship Between Sociorace and One's Social Network

The roles of previous psychological service use and social network variables in beliefs about psychological services were examined with 184 college students. Having friends and family members who used psychological services, being female, and having used psychological services positively related with beliefs about psychological services. Socioracial differences in the effects of previous use of psychological services and social network variables on students’ beliefs about psychological services were found. Suggestions for ways counselors can provide support to students are discussed.     

Interpersonal Counterproductive Work Behaviors: Distinguishing Between Person-Focused Versus Task-Focused Behaviors and Their Antecedents

Purpose

This study proposes a nuanced perspective for conceptualizing interpersonal counterproductive work behaviors (ICWBs) by distinguishing them into behaviors that hinder other workers’ task performance (task-focused ICWBs), and those that are personal in nature (person-focused ICWBs). A relational stress perspective is adopted to examine work-based dependence relational stressor and negative-affect relational stressor as predictors of each category of behavior, with trait competitiveness as a moderator.

Design/Methodology/Approach

Deductive and inductive approaches were used to generate items measuring each type of ICWBs, and the two-factor ICWB structure was validated using data from 136 respondents. Data from a different sample of 125 employees from two organizations were used to test the hypothesized model.

Findings

Work-dependence relational stressor predicted task-focused ICWBs, while negative-affect relational stressor predicted both forms of ICWBs. Trait competitiveness moderated these relationships in different ways.

Implications

This study addresses researchers’ call for fine-grained research that examines specific forms of CWBs and their underlying causes. It demonstrates that ICWBs can go beyond the traditional person-focused behaviors that target other workers’ well-being, to encompass task-focused behaviors that directly impact their performance. By revealing that different relationships at work predict such behaviors, this study informs organizations on how to manage and deter such behaviors among employees.

Originality/Value

This is the first study to distinguish ICWBs into those that are task-focused and person-focused, to provide a validated measure of these two types of behaviors, and to propose and test a model where workplace relationships differently predict such behaviors, moderated by individual’s competitiveness.
