职业探索对大学生求职行为的影响:求职自我效能感的中介作用与情绪调节的调节作用

本研究基于职业发展阶段理论、职业探索社会认知理论等理论考察了职业探索对大学生求职行为的作用机制。采用职业探索量表、求职自我效能感量表、情绪调节量表和求职行为量表对802名大学生进行研究。结果显示：（1）职业探索会显著正向预测大学生求职行为和求职自我效能感均显著正向预测大学生求职行为;（2）求职自我效能感中介了职业探索对大学生求职行为的影响;（3）情绪调节这一变量调节了求职自我效能感对大学生求职行为的影响。因此,职业探索会通过求职自我效能感对大学生求职行为产生影响,且这一影响受到情绪调节的调节。     

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.     

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.     

差异教化观的理念、原则及指向——基于啮缺在《庄子》中的五次出场而论

《庄子》全书围绕啮缺有一条完整的问道故事链,学界鲜有关注。复原、再诠这一故事链,将清晰地看到:首先,对啮缺的最初定位应是一个教化观居于儒、道间的道家内部人士,而《庄子》借许由之口批评啮缺的内容有着深刻蕴意。其次,《庄子》借许由、啮缺所传递的对统治者教化职位的推却姿态有其深层意旨,即强调一种差异教化观,其核心理念是质疑以一统万的社会整合论,并要求警惕改造他者性的道德热情。再次,将《庄子》全书视为一个整体文本,可注意到《庄子》有着在无为与有为间的自觉调适,但原则是"必以无为者主之于先"。最后,以"尊重差异究竟意味着什么"这一问题为中介,可明确《庄子》差异教化观的指向:就个体而言,个体应自觉探求并尊重个体特殊性;就群己关系而言,要尊重他者性及多样性;在理论建设上,希冀社会整合论要以构建一个尊重个体权利、包容个体差异的共同体为方向,并持续修正不适宜的"礼"以不断剥离其"伪"的一面。     

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。     

远期恐惧记忆再巩固更新机制的线索选择性特点

已有动物和人类研究均表明, 通过记忆的再巩固更新机制能有效削弱新形成的条件性恐惧记忆(1天), 并且存在线索选择性特点。然而创伤后应激障碍(PTSD)往往在形成相当一段时间后才能得到治疗, 且现实生活中人们通常一次习得对多个线索的恐惧。因此找到针对多线索创伤记忆的有效治疗方法显得尤为重要。目前未有人研究远期恐惧记忆的再巩固更新机制是否存在线索选择性特点。为探究远期恐惧记忆(>7天)的再巩固更新机制是否同样存在线索选择性特点, 本研究采用被试内实验设计, 以皮肤电作为恐惧反应指标, 多个线索作为条件刺激进行恐惧习得, 习得14天后给被试单独呈现一个线索进行恐惧记忆提取, 10分钟后进行消退训练, 24小时后对不同线索进行自发恢复测试。结果显示：未提取线索的自发恢复程度显著高于提取线索。说明远期记忆(14天)的再巩固更新机制同样存在线索选择性特点, 并确认了提取消退作为一种行为手段对远期恐惧记忆再巩固进行干预的有效性, 对临床干预具有一定指导意义。
