工作记忆成分在传递性推理中的作用

采用双任务(dual-task)实验范式,探讨工作记忆成分在五项系列问题(five-term task)这种传递性推理中的作用。被试为80名大学生,实验材料为32个空间和时间内容的传递性推理题目。结果发现:(1)空间位置和时间关系的推理结果都支持心理模型理论,而不支持形式规则理论。(2)在推理前提的加工阶段,中央执行系统和视空间模板发挥着关键作用,语音环路没有参与;而在结论的推理阶段,工作记忆的三个成分均发挥了作用。(3)传递性推理在工作记忆系统中采用视空间编码进行表征。     

皖江地区员工事故行为心理规律初探

研究表明严重的经济困难因素和政治动乱因素,都是引发工矿员工事故行为的重要时空心理致因。建国后1959年、1960年、1961年“三年经济困难”时期是工矿员工事故行为的高峰,其次是1966年至1976年十年文革动乱时期。一天24时昼夜节律中白班开工后1-2小时是员工事故行为心理高发时段。市场经济条件下低年龄、低工龄、低文化等“三低”员工是事故高暴露群体。     

A base logic for default reasoning

Based on a close study of benchmark examples in default reasoning, such as Nixon Diamond, Penguin Principle, etc., this paper provides an in depth analysis of the basic features of default reasoning. We formalize default inferences based on Modus Ponens for Default Implication, and mark the distinction between “local inferences” (to infer a conclusion from a subset of given premises) and “global inferences” (to infer a conclusion from the entire set of given premises). These conceptual analyses are captured by a formal semantics that is built upon the set-selection function technique. A minimal logic system M of default reasoning that accommodates Modus Ponens for Default Implication and suitable for local inferences is proposed, and its soundness is proved. __________ Translated from Zhexue Yanjiu 哲学研究 (Philosophical Studies), 2003 (special issue) by Ye Feng     

发展性阅读障碍儿童的新词习得及其改善

本研究通过比较重复学习新词时个体眼动模式的变化, 探讨发展性阅读障碍儿童的新词习得及改善途径。实验1以发展性阅读障碍、生理年龄和阅读能力匹配儿童为被试, 采用重复学习新词的范式, 探讨发展性阅读障碍儿童的新词习得。结果发现, 与匹配组相比, 发展性阅读障碍儿童在新词的首次注视时间和凝视时间上需要更多的语境才出现显著下降, 且在总注视时间上表现出更缓慢的下降。表明发展性阅读障碍儿童的新词习得慢于正常儿童。实验2以词间空格和正常无空格两种文本呈现方式, 仍采用重复学习新词范式, 探讨词间空格是否能促进发展性阅读障碍儿童的新词习得。结果发现, 在词间空格条件下, 发展性阅读障碍儿童的新词习得可达到正常儿童的水平。表明作为视觉词切分线索的词间空格, 可促进发展性阅读障碍儿童的新词习得。本研究结果为发展性阅读障碍儿童新词习得提供了一条新的途径。     

社会经济不平等对个体生命史策略的影响——国家发展水平的调节作用

经济不平等不仅是经济问题,也会对个体心理行为产生诸多影响。前人认为,经济不平等会强化个体阶层提升意愿。结合生命史理论,研究提出高不平等将使个体偏好后代质量而非数量,以实现阶层提升,且这一现象在高发展水平国家中更为明显。基于开源数据,通过国家/个人两个水平上的分析发现,在高发展水平国家,经济不平等降低了国家生育率,并使个体更关切后代教育。研究结果可为理解特定经济环境下的个体心理和行为提供参考。     

源于“反常”终于“常理”的禀赋效应

如果忽略收入影响和交易成本, 愿意为一样物品支付的价格应等于愿意出售的价格。而塞勒教授却发现, 现实生活中有一些“反常”现象, 个体会对自己所拥有的物品赋予更高的价值, 造成“愿意支付价格”和“愿意出售价格”的不一致。塞勒利用预期理论中的损失厌恶对这些反常现象进行解释, 并将该现象称为禀赋效应(endowment effect)。此后, 众多研究者从不同角度对该效应进行了探索和论证。文章详细梳理了禀赋效应的多种解释机制, 包括损失厌恶、心理所有权理论、偏差的认知过程以及进化的观点等, 论证了禀赋效应符合“常理”的原因, 同时也探讨了禀赋效应在商业销售策略和政府拆迁政策等方面的应用前景。     

不同睡眠时间参数对学前儿童执行功能的差异化影响

研究选取78名5~7岁的学前儿童为研究对象, 采用睡眠日志法测量了儿童的夜间睡眠比、总睡眠时长和周末补偿睡眠三个睡眠时间的指标, 同时采用母亲报告法收集儿童的消极情绪性, 3个月后采用美国国立卫生研究院(NIH)的一套标准化测量程序评估儿童的执行功能, 探讨三个睡眠时间参数对不同消极情绪性学前儿童执行功能的差异化影响。结果发现, 在控制了儿童的同时性语言能力之后, 夜间睡眠比能够显著预测儿童三个月之后的执行功能; 儿童的消极情绪性与周末补偿睡眠对执行功能的三个子成分存在显著的交互作用。当周末补偿睡眠较少时, 高消极情绪性儿童的执行功能显著低于低消极情绪性儿童; 当周末补偿睡眠较多时, 高消极情绪性儿童的执行功能显著高于低消极情绪性儿童, 该结果符合差别易感性模型。     

Temperament as Risk and Protective Factors in Obesogenic Eating: Relations Among Parent Temperament,Child Temperament,and Child Food Preference and Eating

Children’s food preferences and eating behaviors have implications for their health and weight status, serving as risk or protective factors for obesity. Although parent and child factors influence children’s eating, few studies have examined parent and child temperament simultaneously in relation to child food preference and eating behaviors. The authors addressed this research gap. Participants were 115 ethnically diverse children between 4 and 6?years old and their parents. Measures included parental temperament traits, parental anxiety, child temperament traits, and child food preference and eating behaviors observed using a laboratory procedure. Results show that children preferred candies over grapes, and that aspects of both child and adult temperament were related to child eating behaviors. Child surgency was linked to eating more candies, while child effortful control was linked to eating more grapes. Parent effortful control was related to children’s preference toward grapes. No relations were found between child eating behaviors and child or parent negative affectivity and parental anxiety. Overall, findings suggest that highly impulsive and poorly self-regulated children may be at risk for obesogenic eating habits.     

情感目标和评价的研究

本研究根据学校情感教育的需要,吸收布卢姆的情感目标分类思想,结合我国国情,本研究设定了学校情感教育的目标,同时编制情感目标的测量工具－－情感调查问卷。问卷分为三大部分,分别为测量道德感、理智感和美感。问卷经信度、效率检验,均达到测量学要求、问卷的年龄、性别适用性也较理想。问卷在实际使用中进一步证实了它的有效性。     

Prosocial development in early adulthood: a longitudinal study

Consistency of measures of a prosocial personality and prosocial moral judgment over time, and the interrelations among them, were examined. Participants and friends' reports of prosocial characteristics were obtained at ages 21-22, 23-24, and 25-26 years. In addition, participants' prosocial judgment was assessed with interviews and with an objective measure of prosocial moral reasoning at several ages. Reports of prosocial behavior and empathy-related responding in childhood and observations of prosocial behavior in preschool also were obtained. There was interindividual consistency in prosocial dispositions, and prosocial dispositions in adulthood related to empathy/sympathy and prosocial behavior at much younger ages. Interview and objective measures of moral reasoning were substantially interrelated in late adolescence/early adulthood and correlated with participants' and friends' reports of a prosocial disposition.
