Positive and negative associations underlying ambivalent attitudes

In two studies, we compared the strength of positive and negative associations of ambivalent attitudes to those of nonambivalent attitudes. In Study 1, results from an implicit association task showed that, in contrast to nonambivalent attitudes, ambivalent attitudes were characterized by strong positive and negative associations. In Study 2 responses to ambivalent attitude objects were faster following a positive as well as following a negative prime, compared to a non-word prime, whereas for neutral attitude objects prime type did not influence response times. Results provide direct evidence for the assumption that both positive and negative associations of ambivalent attitudes are relatively strong. Implications for attitude strength and attitude structure are discussed.     

归纳推理中的属性中心性效应

通过三个实验研究了属性的中心性程度对归纳推理的影响,结果表明,在归纳推理中存在属性中心性效应,中心属性比其他属性（次中心属性、再次中心属性）更能影响归纳推理。但属性中心性效应的出现受到了前提对象和结论对象相似性程度的制约,当前提对象和结论对象的相似程度高时,中心属性比其他属性更能影响归纳推理;随着相似性水平的降低,中心属性的归纳推理力度越来越弱,而次中心属性、再次中心属性的归纳推理力度则会依次表现出越来越强的趋势,到最后当前提对象和结论对象的属性完全不相似时,最次中心属性的归纳推理力度达到最高水平,而中心属性的归纳推理力度则降低到最低水平。由于再次中心属性的归纳推理力度的最高水平没有显著高于随机水平,而中心属性的归纳推理力度的最低水平却显著低于随机水平,因此,研究者认为,在前提对象和结论对象完全不相似的情况下,被试将确信不能采用中心属性来进行归纳推理的力度判断,而采用猜测的方式选择了肯定可以排除的项目之外的其他项目,这体现了具有不确定的归纳推理活动的过程的典型特征     

Working harder with the out-group: The impact of social category diversity on motivation gains

This paper examines the influence that social category diversity (i.e., working with an in-group or out-group member) has on individual levels of motivation. The results of two experiments provide evidence that individuals increase their effort more when being outperformed by an out-group instead of an in-group member (Experiment 1), but only when the potential for social comparison is present (Experiment 2). We discuss the implications of this research for understanding how and why social category diversity may impact individual levels of motivation.     

从对框架效应的分析看风险决策的神经基础

对风险决策的研究近年来一直是微观经济学和心理学的热门,但是从传统的决策理论到主张有限理性的预期理论大多是对决策行为的研究,决策的心理机制一直是无法解释的黑箱子。令人兴奋的是近几年来神经科学家及其他领域的学者开始用先进的神经心理学的方法来研究风险决策,试图理解神经过程调节风险决策行为的方式。文章从分析违背“不变性”原则的框架效应入手,从正反框架、确定选择和风险选择、风险规避和风险寻求、高估小概率事件几个方面,全面分析风险决策可能的神经基础。在总结已有研究的基础上提出了把风险决策研究扩展到不确定决策,把风险决策中的一次决策研究扩展到多次决策的研究思路     

数字的空间特性

当要求被试对数字进行奇偶判断时,左手对小数的反应较快,而右手对大数的反应较快,该现象被称为空间数字反应编码联合效应（SNARC效应）。大量研究证实了SNARC效应的存在,该效应表明人类对数字的加工受空间表征和空间注意的影响。该文系统地回顾了SNARC效应存在及其发生阶段的证据,对比了Simon效应与SNARC效应,最后尝试着从空间注意的角度挖掘数字和空间的本质联     

泛文化的自尊——基于中国大学生的研究证据

过去一直认为,自尊是人类普遍的需要,是泛文化的。但是,过去十多年来,这一观点受到严重挑战。其主要理由是许多跨文化的研究显示集体主义文化下个体的自尊显著低于西方,少有自我促进的迹象。但是,几乎所有这样的证据都是来自自陈式测量。由于自陈式测量难以避免自我展现（Self-presentation）或社会期许（Social Desirability）的影响,并且严重依赖于个体的自我报告,本研究采用新的能够防止社会期许的影响并能触及无意识的内隐测量——阈下评价性启动（Subliminal Evaluative Priming）程序,对中国大学生的自尊进行了研究。结果发现中国大学生对自我持有显著的积极、肯定的评价,中国人存在内隐自尊。这表明,集体主义文化下的个体的自尊需要是存在的,只是以内隐的方式表现或在自我展现的影响最小化后表现出来。这一发现和自尊的泛文化论是一致的     

大学生职业决策和自尊、成就动机的关系

在应用自尊量表(SES)和成就动机量表(AMS)对106名大学生(男生46名,女生60名)进行调查的基础上,通过设计框架性职业决策情景,探究了大学生职业决策和自尊、成就动机的关系。结果发现:(1)成就动机中避免失败变量与框架效应的交互作用对大学生职业决策倾向性有显著性影响;(2)自尊水平对大学生职业决策倾向性存在显著性作用;(3)框架效应在大学生职业决策中发生作用,对大学生的职业决策倾向性有显著的影响。     

Hand function,not proximity,biases visuotactile integration later in object processing: An ERP study

Behavioral studies document a functional hand proximity effect: objects near the palm, but not the back of the hand, affect visual processing. Although visuotactile bimodal neurons integrate visual and haptic inputs, their receptive fields in monkey cortex encompass the whole hand, not just the palm. Using ERPs, we investigated whether hand function influenced the topology of integrated space around the hand. In a visual detection paradigm, target and non-target stimuli appeared equidistantly in front or in back of the hand. Equivalent N1 amplitudes were found for both conditions. P3 target versus non-target amplitude differences were greater for palm conditions. Hand proximity biased processing of visual targets equidistant from the hand early in processing. However, hand function biases emerged later when targets were selected for potential action. Thus, early hand proximity effects on object processing depend on sensory-reliant neural responses, whereas later multisensory integration depend more on the hand’s functional expertise.     

Learning and transfer of calorie information

This study compared generating information about food to viewing and verbally producing that information for learning and transfer. Specifically, during training, a list of food items was shown, and some participants generated either real calories (Experiment 1) or fabricated prices (Experiment 2) associated with those foods with feedback provided (seeding), some viewed and read aloud values provided (viewing), and others read aloud the names of the items with no values provided (control). All participants were tested immediately and 1 week later on both old and new foods. In both experiments, the seeding and viewing conditions showed more learning than the control condition, and only the experimental conditions showed transfer of learning from old to new foods, with advantages found for seeding over viewing only in some cases. The results are discussed in terms of the seeding, testing, generation, and production effects, as well as their applications to health and policy.     

红色及图形表征对健康行为的助推作用

本研究旨在通过3个实验从信息凸显的角度探讨红色图形对健康行为的助推作用。实验一和实验二分别采用星号图和直条图，通过操纵图形颜色或装有实验材料的信封颜色，以探讨数量信息表征方式（图形 vs. 数字）及颜色（红色 vs. 蓝色、黑色或白色）对健康风险回避行为的影响。实验三将针对宫颈癌疫苗接种这一健康行为，采用更加形象的人物杆形图进一步考察在不同决策框架下（损失/收益）红色图形能否有效助推个体的健康行为意愿。结果发现，在损失及收益情景下，红色图形均能稳定助推个体的健康行为，但当用信封颜色操纵颜色背景时，红色的影响力会降低。结果支持：红色图形可有效助推个体的健康行为。
