言语想象的神经机制

言语想象不仅在大脑预处理机制方面起到重要的作用,还是目前脑机接口领域研究的热点。与正常言语产生过程相比,言语想象的理论模型、激活脑区、神经传导路径等均与其有较多相似之处。而言语障碍群体的言语想象、想象有意义的词语和句子时的脑神经机制与正常言语产生存在差异。鉴于人类言语系统的复杂性,言语想象的神经机制研究还面临一系列挑战,未来研究可在言语想象质量评价工具及神经解码范式、脑控制回路、激活通路、言语障碍群体的言语想象机制、词语和句子想象的脑神经信号等方面进一步探索,为有效提高脑机接口的识别率提供依据,为言语障碍群体的沟通提供便利。     

Superheroes for change: Physical safety promotes socially (but not economically) progressive attitudes among conservatives

Across two studies, we find evidence for our prediction that experimentally increasing feelings of physical safety increases conservatives' socially progressive attitudes. Specifically, Republican and conservative participants who imagined being endowed with a superpower that made them invulnerable to physical harm (vs. the ability to fly) were more socially (but not economically) liberal (Study 1) and less resistant to social change (Study 2). Results suggest that socially (but not economically) conservative attitudes are driven, at least in part, by needs for safety and security.     

社会支持对流动儿童社会退缩的影响:心理弹性的中介作用

目的:探讨心理弹性在社会支持与流动儿童社会退缩之间的中介作用。方法:采用社会支持评定量表、青少年心理弹性量表和班级戏剧量表对258名流动儿童进行调查。结果表明:(1)活跃退缩与社会支持、心理弹性呈显著负相关; 安静退缩与社会支持相关不显著,与心理弹性呈显著负相关; 社会支持与心理弹性呈显著正相关;(2)社会支持、心理弹性显著负向预测流动儿童的活跃退缩;(3)心理弹性在社会支持与流动儿童活跃退缩之间具有完全中介作用。     

反馈时间、反馈类型和掩蔽类型对概率类别学习的影响

通过操纵反馈时间(即时,延迟)、反馈类型(简单,丰富)和掩蔽类型(塔罗牌,空白矩形),考察概率类别学习的学习机制。结果发现:(1)被试的学习成绩在即时反馈条件下显著优于在延迟反馈条件下;(2)在即时反馈条件下,仅给予简单反馈,被试虽能出色地完成天气预报任务,但是不能正确地判断卡片预测晴天的概率,倾向内隐学习;(3)在其他条件下,被试能正确地判断卡片预测晴天的概率以及各卡片在天气预报任务中预测天气的重要程度,表明被试能外显地意识到这些线索的作用。综上,概率类别学习采用的是双系统学习机制,既依赖内隐学习,又依赖外显学习。     

Confucian dynamism work values and team performance: A multiple‐level analysis

In this study we clarified the multiple‐level effects of Confucian‐related work values, including self‐discipline and interpersonal ethics, on the performance of individuals and the team. Empirical data of 70 work teams with 472 team members from Taiwanese enterprises were collected to test our hypotheses. Results showed that, at the group level, shared team values of interpersonal ethics were positively related to team performance through the partial mediation of team cooperation. For cross‐level effect, shared team values of interpersonal ethics and individual member's self‐discipline values were both positively related to individual performance. The implications of Confucian dynamism work values on contemporary organizational management and indigenous Chinese team theories were provided.     

Exercise type relates to inhibitory and error processing functions in older adults

ABSTRACT

This study investigated the association between exercise type and inhibition of prepotent responses and error detection. Totally, 75 adults (M = 68.88 years) were classified into one of three exercise groups: those who were regular participants in open- or closed-skill forms of exercise, and those who exercised only irregularly. The participants completed a Stroop and task-switching tasks with event-related brain potentials (ERPs) recorded. The results revealed that regular exercisers displayed faster reaction times (RTs) in the Stroop task compared with irregular exercisers. The open-skill exercisers exhibited smaller N200 and larger P300a amplitudes in the Stroop task compared with irregular exercisers. Furthermore, the open-skill exercisers showed a tendency of shorter error-related negativity latencies at the task-witching test. The findings suggest that older adults may gain extra cognitive benefits in areas such as inhibition functioning and error processing from participating in open-skill forms of physical exercises.     

未来时间洞察力的目标作用

未来时间洞察力是个体对未来时间的认知、体验和行动（或行动倾向）的一种人格特质,其目标不仅架起了现在与未来的桥梁,也影响个体的认知与行为,并且不同目标还具有不同的动力作用。但个体如何建构未来目标、确立优势目标等,需做进一步研究。     

显性自恋与隐性自恋:自恋人格的心理学探析

自恋是一种形式多样化的综合性人格构造,它具有两种不同的形式,即显性自恋和隐性自恋。本研究在文献综述、开放式问卷调查和个别访谈的基础上,编制了自恋人格问卷。经对大学生被试进行测查,结果表明：（1）自编的自恋人格问卷具有较好的信度和效度。（2）因素分析得出显性自恋的四个维度是：权欲、优越感、特权感和自我钦羡;隐性自恋的三个维度是：易感质、特权感和自我钦羡。（3）显性自恋和隐性自恋与心理健康有着不同的关联：前者与心理异常症状不存在显著相关,而后者存在显著正相关。     

关于临床决策问题

医生在临床工作中做出明确诊断,并据此给予有效的处理均属于决策过程。制定决策的整个过程,同时也是进行决策思维的过程。近年来高新技术的迅猛发展以及医疗费用急剧增加,使制定决策更加复杂。如何进行正确的决策思维,做出最切实可行的和最佳的决策,对避免决策的盲目性、局限性及惰性具有重要的现实意义。     

关于道教辟谷养生术的综合考察

道教辟谷养生术的产生与发展是社会局势、道教信仰、养生实践多重因素综合作用的结果;其主要类型有服药(饵)辟谷、服气辟谷、服(符)水辟谷、服石辟谷等,各有一套操作规程;拨开道教神学云雾,辟谷养生之精要在于慎重选择食材和适当节制食量。
