条件推理与概率判断

选取6个具体内容的条件命题和1个纯形式的条件命题作为实验材料,以大学生为被试,深入探讨了条件推理的认知加工机制。结果发现,大学生被试对四种推理形式的认可程度主要与范畴前提的概率值成正比,条件推理似乎是一种基于概率判断的直觉而高效的认知加工过程,进一步证实了Oaksford（2000）以及Evans（2003）等人的观点。     

任务情境和证据信息对青少年贝叶斯推理的影响研究

采用生活情境测查任务和经典测查任务探讨了任务情境对青少年贝叶斯推理的影响,以及生活情境测查任务中不同证据信息对青少年贝叶斯判断的影响作用.结果表明:(1)在生活情境测查任务中,从小学六年级到大学二年级,被试的贝叶斯推理能力稳步缓慢提升(相邻的两个被试组之间差异不显著,而不相邻的两个被试组之间差异更容易达到显著水平),发展没有出现加速期,而经典测查任务情境下没有表现出年龄差异;(2)贝叶斯推理作为条件概率的判断不仅受任务情境的影响,而且同一任务情境中不同证据信息也会影响贝叶斯判断.当证据信息与先验信念一致时,被试可以充分利用线索进行推理.     

Bindings in working memory: The role of object-based attention

Over the past decade, it has been debated whether retaining bindings in working memory (WM) requires more attention than retaining constituent features, focusing on domain-general attention and space-based attention. Recently, we proposed that retaining bindings in WM needs more object-based attention than retaining constituent features (Shen, Huang, & Gao, 2015, Journal of Experimental Psychology: Human Perception and Performance, doi: 10.1037/xhp0000018). However, only unitized visual bindings were examined; to establish the role of object-based attention in retaining bindings in WM, more emperical evidence is required. We tested 4 new bindings that had been suggested requiring no more attention than the constituent features in the WM maintenance phase: The two constituent features of binding were stored in different WM modules (cross-module binding, Experiment 1), from auditory and visual modalities (cross-modal binding, Experiment 2), or temporally (cross-time binding, Experiments 3) or spatially (cross-space binding, Experiments 4–6) separated. In the critical condition, we added a secondary object feature-report task during the delay interval of the change-detection task, such that the secondary task competed for object-based attention with the to-be-memorized stimuli. If more object-based attention is required for retaining bindings than for retaining constituent features, the secondary task should impair the binding performance to a larger degree relative to the performance of constituent features. Indeed, Experiments 1–6 consistently revealed a significantly larger impairment for bindings than for the constituent features, suggesting that object-based attention plays a pivotal role in retaining bindings in WM.     

中小学教师职业倦怠的现状及相关因素研究

采用修订的Maslach教师职业倦怠问卷对647名中小学教师进行了调查,结果表明: (1)我国教师的职业倦怠整体程度不高,但与我国护士和美国教师相比,其个人成就感明显偏低。(2)男女教师的情绪衰竭和非人性化程度无显著差异,女教师成就感显著高于男教师。 (3)中专学历的教师的情绪衰竭感显著低于大专和本科学历的教师。 (4)小学教师的个人成就感显著高于中学教师,而非人性化程度明显比中学教师低,高中教师比小学和初中教师具有更强的情绪衰竭感。 (5)教龄为5-10年的小学教师和教龄为11-20年的中学教师,最易出现情绪衰竭感。(6)教龄在5年内的初中男教师和教龄在11-20年的初中女教师,可能是职业倦怠的高发人群。     

再探猜谜作业中“顿悟”的ERP效应

采用事件相关电位(ERP)技术探讨顿悟问题（字谜）解决中提供答案后的脑内时程动态变化。结果发现,在250~400 ms内,“有顿悟”和“不理解”比“无顿悟”的ERP波形均有一个更为负向的偏移。在“有顿悟—无顿悟”和“不理解—无顿悟”的差异波中,这个负成分的潜伏期约为320 ms (N320),地形图显示,N320在中后部活动最强。进一步对“有顿悟—无顿悟”差异波作偶极子溯源分析,发现N320主要起源于扣带前回（ACC）附近。这似乎表明,N320可能反映了提供答案瞬间新旧思路之间的认知冲突,但是却不能真正揭示顿悟问题解决中思维定势的成功突破以及“恍然大悟”所对应的独特脑内时程变化     

序列学习下内隐记忆意识性的动态发展特征

该研究采用事件相关电位方法(ERP),通过算式符号判别任务研究大学生序列学习下内隐记忆意识性动态发展的时空分布特征。研究采用算式符号判别任务探讨在不同反应-刺激时间间隔条件下,序列学习过程中伴随的对整个算式刺激的内隐记忆意识性的影响及时空分布特征。实验结果表明:1)在对序列规则进行内隐学习的过程中同时可以伴随内隐记忆的发生,RSI的增加导致内隐记忆意识性增加;2)不同意识性程度的内隐记忆激活脑区的头皮分布存在差异。意识性程度高激活脑区范围更广泛和弥散,意识性程度低激活脑区范围较小和集中。意识性由大到小激活脑区有由后(枕区)向前(额区)连续变化的趋势。     

大学生主观幸福感的跨文化研究:来自48个国家和地区的调查报告

旨在考察主观幸福感的基本状况,通过对来自48个国家和地区的10018名大学生被试施测《国际大学调查》(ICS)问卷(分A卷和B卷),对施测结果进行相关分析和回归分析,发现积极情感、消极情感、生活满意感、自我体验和外在准则都是主观幸福感的有效预测变量。在回归分析的基础上采用优势分析方法评估了主观幸福感各预测变量在预测主观幸福感时的相对重要性。优势分析结果表明,预测主观幸福感时积极情感最为重要,其次是生活满意感。这再一次验证主观幸福感主要是由情感和认知两方面预测的观点。     

Family boundary characteristics,work–family conflict and life satisfaction: A moderated mediation model

Although work–family border and boundary theory suggest individuals' boundary characteristics influence their work–family relationship, it is largely unknown how boundary flexibility and permeability mutually influence work–family conflict and subsequent employee outcomes. Moreover, the existing work–family conflict research has been mainly conducted in the United States and other Western countries. To address these gaps in the work–family literature, the present study examines a moderated mediation model regarding how family boundary characteristics may influence individuals' work–family conflict and life satisfaction with a sample of 278 Chinese full‐time employees. Results showed that employees' family flexibility negatively related to their perceived work interference with family (WIF) and family interference with work (FIW), and both these two relationships were augmented by individuals' family permeability. In addition, WIF mediated the relationship between family flexibility and life satisfaction; the indirect effect of family flexibility on life satisfaction via WIF was stronger for individuals with higher family permeability. The theoretical and managerial implications of these findings are discussed.     

Regional gray matter volume is associated with rejection sensitivity: A voxel-based morphometry study

Rejection sensitivity (RS) can be defined as the disposition that one tends to anxiously expect, readily perceive, and intensely react to rejection. High-RS individuals are more likely to suffer mental disorders. Previous studies have investigated brain activity during social rejection using different kinds of rejection paradigms and have provided neural evidence of individual differences in response to rejection cues, but the association between individual differences in RS and brain structure has never been investigated. In this study, voxel-based morphometry (VBM) was used to investigate the relationship between gray matter volume (GMV) and RS in a large healthy sample of 150 men and 188 women. The participants completed the RS Questionnaire and underwent an anatomical magnetic resonance imaging scan. Multiple regression was used to analyze the correlation between regional GMV and RS scores, adjusting for age, sex, and total brain GMV. These results showed that GMV in the region of the posterior cingulate cortex/precuneus was negatively associated with RS, and GMV in the region of the inferior temporal gyrus was positively correlated with RS. These findings suggest a relationship between individual differences in RS and GMV in brain regions that are primarily related to social cognition.
