Parental Cognitive Errors Mediate Parental Psychopathology and Ratings of Child Inattention

We investigate the Depression‐Distortion Hypothesis in a sample of 199 school‐aged children with ADHD‐Predominantly Inattentive presentation (ADHD‐I) by examining relations and cross‐sectional mediational pathways between parental characteristics (i.e., levels of parental depressive and ADHD symptoms) and parental ratings of child problem behavior (inattention, sluggish cognitive tempo, and functional impairment) via parental cognitive errors. Results demonstrated a positive association between parental factors and parental ratings of inattention, as well as a mediational pathway between parental depressive and ADHD symptoms and parental ratings of inattention via parental cognitive errors. Specifically, higher levels of parental depressive and ADHD symptoms predicted higher levels of cognitive errors, which in turn predicted higher parental ratings of inattention. Findings provide evidence for core tenets of the Depression‐Distortion Hypothesis, which state that parents with high rates of psychopathology hold negative schemas for their child's behavior and subsequently, report their child's behavior as more severe.     

Effect of 45‐Day −6° Head‐Down Bed Rest on Cooperation and Aggression

High levels of cooperation and low aggression seem obviously vital to the successful implementation of space missions. To elucidate the effect of microgravity on these behaviors, we investigated whether cooperative and aggressive behaviors would be affected in 16 male volunteers during 45‐day ?6° head‐down bed rest, which is a reliable simulation model for most physiological effects of spaceflight. We used an ultimatum game task to evaluate the cooperative behavior and a revised competitive reaction time test to evaluate the aggressive behavior simultaneously. We found that (1) the participants became less cooperative in the post‐bed rest phase in comparison with the pre‐bed rest phase and (2) the participants became more aggressive in the in‐bed rest phase in comparison with the pre‐bed rest phase. These findings provide evidence that head‐down bed rest may affect both cooperative and aggressive behaviors in males, suggesting an important perspective for future studies in space psychology.Copyright © 2017 John Wiley & Sons, Ltd.     

汉语口语产生中音节和音段的促进和抑制效应

采用图画-词汇干扰实验范式, 通过比较即时命名、延迟命名以及延迟命名与发音抑制任务的结合, 考察了汉语口语产生中音节和音段在单词形式编码的不同阶段所产生的效应。与无关条件相比, 在包含音韵编码、语音编码和发音阶段的即时命名任务中, 音节相关和音段相关条件显著地缩短了图画命名时间, 表现出音节和音段促进效应; 在包含发音阶段的延迟命名任务中, 音节相关和音段相关条件显著地延长了图画命名的时间, 表现出音节和音段抑制效应; 在包含语音编码和发音阶段的延迟命名和发音抑制结合的任务中, 音段相关条件显著地延长了图画命名时间, 表现出音段抑制效应。结果表明, 音节和音段的促进效应发生在汉语口语词汇产生中的音韵编码阶段, 音节和音段的抑制效应可能发生在语音编码或者发音阶段。效果量(Cohen d)的分析表明音节的促进效应强, 而音段的促进效应弱, 音节是音韵编码过程的合适单元, 为合适单元假设提供了支持证据。与音节相比, 音段在语音编码和发音阶段的效应量较大, 表明音段在运动执行过程中可能起了相对重要的作用, 支持了口语产生中词汇表征准备阶段与运动阶段分离的观点。     

创造性思维的性别差异

创造性思维是推动科学技术进步和人类社会与文化发展的重要心理基础。人类两性分别在创造性思维的聚合思维和发散思维方面表现出显著的行为和神经活动差异。在发散思维方面, 女性优势相对明显; 但在聚合思维方面, 男性具有一定优势。两性在不同类型创造性思维方面的相对优势与大脑两半球的加工优势有密切联系, 且受到包括性别作用等因素的调节。研究对这些问题进行了系统探讨, 并就当前研究不足和未来趋势进行了展望。     

追求积极情绪可能导致消极后果及其机制探讨

近年来有关研究发现了追求积极情绪可能给个体带来消极后果, 即个体越追求积极情绪, 他们很可能越体验不到幸福, 并称之为“追求积极情绪的悖论”。当个体把追求积极情绪作为目标时, 可能会(1)为个人的快乐设定过高的标准; (2)通过不恰当的活动去获得快乐; (3)监控获得快乐的过程, 妨碍了沉浸体验。这三个心理过程导致了“追求积极情绪的悖论”。未来的研究应该进一步关注：(1)全面揭示追求积极情绪的后果; (2)揭示追求积极情绪导致消极后果的生理神经机制; (3)追求积极情绪的跨文化研究; (4)探索正确追求积极情绪的方式。     

所有制与行业性质对组织学习动力作用的研究

本文探讨了组织特性（所有制和行业性质）对组织学习动力的作用。采用多元方差分析,研究了1074名各类企业员工和管理者的组织学习动力,分别探讨了组织特性对其学习动力的作用。结果表明：1）组织所有制性质影响组织学习动力;2）组织的行业性质影响组织学习动力;3）组织的所有制和行业性质存在交互作用。各类组织学习动力排序的结果是（1）在行业性质上：国营旅游业〉文教卫生〉金融业〉制造业;非国营制造业〉文教卫生〉金融业〉旅游业;（2）在所有制性质上：旅游业国营企事业单位〉非国营企业,制造业非国营企业〉国营企事业,金融业国营企业〉非国营企业．文教卫生行业非国营企业〉国营企业。

师生关系对研究生自我效能感的影响:有调节的中介模型

为探讨师生关系与自我效能感的关系,并着力考察专业认同和导师负面评价恐惧在其中所起的作用,采用一般自我效能感量表、研究生师生关系感知问卷、专业认同量表、害怕导师负面评价量表对458名研究生进行调查,结果发现：（1）师生关系可正向预测研究生自我效能感;专业认同在两者间起中介作用;（2）导师负面评价恐惧在师生关系通过专业认同影响自我效能感的中介模型后半段起调节作用,即对于导师负面评价恐惧较高的研究生来说,专业认同对其自我效能感的影响更大。研究结果揭示了师生关系对自我效能感的作用机制。     

Endurance factors improve hippocampal neurogenesis and spatial memory in mice

Physical activity improves learning and hippocampal neurogenesis. It is unknown whether compounds that increase endurance in muscle also enhance cognition. We investigated the effects of endurance factors, peroxisome proliferator-activated receptor δ agonist GW501516 and AICAR, activator of AMP-activated protein kinase on memory and neurogenesis. Mice were injected with GW for 7 d or AICAR for 7 or 14 d. Two weeks thereafter mice were tested in the Morris water maze. AICAR (7 d) and GW improved spatial memory. Moreover, AICAR significantly, and GW modestly, elevated dentate gyrus neurogenesis. Thus, pharmacological activation of skeletal muscle may mediate cognitive effects.     

Seeing yourself helps you see others

It has been proposed that self-face representations are involved in interpreting facial emotions of others. We experimentally primed participants' self-face representations. In Study 1, we assessed eye tracking patterns and performance on a facial emotion discrimination task, and in Study 2, we assessed emotion ratings between self and nonself groups. Results show that experimental priming of self-face representations increases visual exploration of faces, facilitates the speed of facial expression processing, and increases the emotional distance between expressions. These findings suggest that the ability to interpret facial expressions of others is intimately associated with the representations we have of our own faces.
