重症患者的镇痛镇静治疗——理想与现实的渐近

重症患者的镇痛镇静治疗逐渐为广大重症医学医护人员所重视,开展亦日渐普及.首先在实践中发现问题,思考学习产生认识;并借鉴历史经验,少走弯路提高起点;再到实践中验证认识,逐渐发现问题不断改善进步.这一历程印证了在哲学认识论领域常说的＆quot;实践-认识-再实践-再认识,循环往复,以至无穷＆quot;这一规律,临床镇痛镇静治疗的现实与重症医学治病救命的理想逐渐趋近.     

Friends, fun, frustration and fantasy: Child motivations for video game play

Although a considerable amount of attention has examined potential positive and negative consequences of video game play in children, relatively little research has examined children’s motivations for using games. The current study hopes to address this gap in the literature by examining children’s motivations for video game play in a large sample of youth (n = 1254). Results indicated that video game use was common, and often a social activity. Social play was mainly predicted by motivations related to socialization, fun/challenge and current stress level. Preference for violent games was more common in males and predicted by fun/challenge motivations and beliefs such games could be cathartic for stress. Children with clinically elevated levels of depressive and ADHD symptoms did not play more games, or more violent games, but were more inclined to endorse catharsis motivations for video game use. Results from this study provide understanding of what motivates children to use games, and how the motivations of children with symptoms of psychosocial problems (as identified via subscales of the Pediatric Symptom Checklist) may differ from others.     

An Investigation of the Associations Between Contingent Self-Worth and Aspirations Among Iranian University Students

This study investigated the novel associations between intrinsic and extrinsic aspirations and internal and external domains of contingent self-worth among a sample of 502 Iranian university students. We found a meaningful pattern showing that intrinsic aspirations were positively associated with internal domains, whereas extrinsic aspirations were positively associated with external domains. Our survey data also suggested that the factor structure of the Aspiration Index, as well as the factor structure of the Contingencies of Self-Worth Scale in our Iranian sample were consistent with factor structures of foreign samples. Finally, the types of aspirations and domains of contingencies of self-worth meaningfully predicted variables related to well-being, confirming previous research. We discuss the nature of the associations between the aspirations and the domains of contingent self-worth.     

Extensions of Priest-da Costa Logic

In this paper, we look at applying the techniques from analyzing superintuitionistic logics to extensions of the cointuitionistic Priest-da Costa logic daC (introduced by Graham Priest as “da Costa logic”). The relationship between the superintuitionistic axioms- definable in daC- and extensions of Priest-da Costa logic (sdc-logics) is analyzed and applied to exploring the gap between the maximal si-logic SmL and classical logic in the class of sdc-logics. A sequence of strengthenings of Priest-da Costa logic is examined and employed to pinpoint the maximal non-classical extension of both daC and Heyting-Brouwer logic HB . Finally, the relationship between daC and Logics of Formal Inconsistency is examined.     

高中生强迫思考与抑郁状态：压力知觉的中介作用及不反应的调节作用

青少年时期是抑郁的高发时期,也是抑郁预防的重要时间窗口。为探讨强迫思考倾向和抑郁状态的关系及其作用机制,采用问卷法对501名高中生进行调查。结果发现：（1）高中生强迫思考倾向完全通过压力知觉正向预测抑郁状态;（2）不反应在强迫思考倾向与压力知觉之间起调节作用,当不反应水平较高时,强迫思考倾向通过压力知觉预测抑郁状态的作用较弱。研究结果有助于揭示强迫思考倾向对高中生抑郁状态的影响及作用机制,对积极预防高中生抑郁具有一定的启示。     

Emoji图像符号的社交功能及应用

Emoji是一种从最初模仿挪用日式动漫符号, 到后来日益扩展其使用范围的图像符号体系。自从1999年Shegetaka Kurita创造Emoji以来, Emoji不断获得充实和发展, 目前已成为数字交流中代替肢体动作、面部表情等非语言线索的主要形式, 并成为全球普遍使用的交流工具。Emoji本身具有有趣、形象、生动和幽默等特点, 在网络交流中具有表达情感、加强表达、改变语气、维持或增进人际关系等功能。同时, 其使用会受到性别、文化、语境和平台等因素的影响。目前, 随着Emoji的不断发展和广泛使用, 其应用范围已经扩展至网络交流之外的心理测量、商业营销、法律判决以及情感分析等领域, 具有广泛的应用和研究价值。未来可以从以下几个方面进一步深入研究：(1)进一步探索Emoji在网络交流中的应用和未来发展趋势; (2)加大对Emoji在其他领域中应用情况的进一步研究; (3)更加深入探索Emoji的神经生理机制; (4)从认知加工角度来探讨Emoji在网络交流中的积极效果。     

压力下一搏：压力如何影响个体风险寻求

压力促使个体风险寻求已得到许多研究的验证和支持, 但对于该现象背后的根本机制缺乏深入探讨和整合。模型指出, 压力诱发认知资源损耗和心理需要失衡, 导致个体执行控制功能减弱, 奖赏寻求增加, 这两者引起对风险选项价值的高估、风险感知的降低和启发式决策策略的使用, 最终导致风险寻求。期望效用论、预期理论、双系统理论和风险敏感理论的视角能各有侧重地解析模型中的路径。最后, 基于模型梳理了边界条件, 并提出未来可关注压力下执行功能、认知和情绪的交互以及慢性压力的影响和调控。     

动作自主性与结果性质对不同预测性条件下施动感的影响

采用时间估计法考察动作自主性水平、动作结果性质(利己、利他、中性)以及结果是否可预测对施动感的影响。结果发现, 高自主性的自由选择条件比低自主性的服从条件增强了个体的施动感, 且不受动作结果性质与结果是否可预测的影响; 在低自主性的服从条件下, 当结果可预测时利己结果比利他结果的施动感更强, 而在结果不可预测时利己和利他结果的施动感没有区别, 但均弱于中性结果。这揭示出动作的主观意愿在施动感产生过程中的重要作用, 同时在自主性较低的服从条件下, 对利己或利他道德属性的动作结果能否被预测, 对个体的施动感产生了不同的影响。研究结果说明具有利己或利他道德属性的动作对施动感会产生自上而下的调节作用, 且这种调节作用在低自主条件下较为突显。     

Maturation constrains the effect of exposure in linking language and thought: evidence from healthy preterm infants

The power of human language rests upon its intricate links to human cognition. By 3 months of age, listening to language supports infants’ ability to form object categories, a building block of cognition. Moreover, infants display a systematic shift between 3 and 4 months – a shift from familiarity to novelty preferences – in their expression of this link between language and core cognitive processes. Here, we capitalize on this tightly‐timed developmental shift in fullterm infants to assess (a) whether it also appears in preterm infants and (b) whether it reflects infants’ maturational status or the duration of their postnatal experience. Healthy late preterm infants (N = 22) participated in an object categorization task while listening to language. Their performance, coupled with that of fullterm infants, reveals that this developmental shift is evident in preterm infants and unfolds on the same maturational timetable as in their fullterm counterparts.
