儿童混合表情识别的发展及与基本表情识别的关系

以193名儿童为被试,采用表情识别范式,考察5岁、6岁及8岁儿童的基本表情识别能力和混合表情识别能力,探讨了儿童在这一年龄段中混合表情识别能力的发展特点,及其与基本表情识别能力之间的关系。研究发现：基本表情识别能力在5岁时已发展良好,混合表情识别能力在8岁时仍需完善,后者是前者的深化,同时还包含对多种表情进行辨认的能力;两种表情识别能力构成了更加完整的表情识别图景。     

性别二态线索对男性面孔吸引力影响的方法差异之争

性别二态线索(男性化-女性化线索)对男性面孔吸引力的影响一直存在不一致的结果,研究者主要从方法差异对此不一致性进行解释.本文首先对操作男性化面孔刺激的不同计算机图像处理技术进行了阐述,主要包括性别二态技术、感知男性化技术和青春期发展技术,并进一步梳理了以往采用不同技术进行比较的相关研究,最后对未来研究提出了展望.     

运算动量效应的理论解释及其发展性预测因素

了解运算偏差的形成与发展对探索算数运算系统的内在机制具有重要意义,早期的算数运算能力是儿童理解和进行复杂数学运算的基础。运算动量偏差是指个体在进行基本数学运算时倾向于高估加法运算结果而低估减法运算结果的一种运算偏差,主要包括三种理论解释,即注意转移假说、启发式解释和压缩解释。鉴于运算动量效应在成年群体中相对稳定却在不同发展阶段儿童中存在不一致的证据,数学能力的提高与空间注意的成熟可结合不同的理论解释来阐明儿童发展过程中运算动量效应的变化趋势。未来可以进一步整合多种研究任务以揭示运算动量效应的发展轨迹,考察数量表征系统与运算动量效应间的关联,探究运算动量效应在不同运算符号中的稳定性,探讨不同因素共同作用对运算动量效应的影响,并设计有关数学能力的干预措施以减少运算动量效应这一运算偏差。     

于阗僧人法藏与兖州宋代金棺刍议

本文考证于阗僧人法藏入宋,应是使臣身份。于阗的战乱及亡国,促成法藏留居兖州。兴隆塔地宫出土的金棺纹样,包含了诸多于阗因素,是宋代佛教考古的重大发现。兴隆塔是中原人民与新疆人民友好交往的纪念碑式建筑。     

蒋湘南与伊斯兰哲学

清代著名回族学者蒋湘南不是穆斯林,但是通过将蒋湘南思想的核心观念和伊斯兰教汉文经典(汉塔布)的相关文字作比较,可以看出,伊斯兰哲学对于蒋湘南的思想,有着根本性的影响,是蒋湘南思想建构的基础资源.伊斯兰哲学对中国思想的影响,需要重视.     

Relevance theory,pragmatic inference and cognitive architecture

Relevance Theory (RT) argues that human language comprehension processes tend to maximize “relevance,” and postulates that there is a relevance-based procedure that a hearer follows when trying to understand an utterance. Despite being highly influential, RT has been criticized for its failure to explain how speaker-related information, either the speaker’s abilities or her/his preferences, is incorporated into the hearer’s inferential, pragmatic process. An alternative proposal is that speaker-related information gains prominence due to representation of the speaker within higher level goal-directed schemata. Yet the goal-based account is still unable to explain clearly how cross-domain information, for example linguistic meaning and speaker-related knowledge, is integrated within a modular system. On the basis of RT’s cognitive requirements, together with contemporary cognitive theory, we argue that this integration is realized by utilizing working memory and that there exist conversational constraints with which the constructed utterance interpretation should be consistent. We illustrate our arguments with a computational implementation of the proposed processes within a general cognitive architecture.

Estimation of Controlled Direct Effects in Longitudinal Mediation Analyses with Latent Variables in Randomized Studies

Abstract

In a randomized study with longitudinal data on a mediator and outcome, estimating the direct effect of treatment on the outcome at a particular time requires adjusting for confounding of the association between the outcome and all preceding instances of the mediator. When the confounders are themselves affected by treatment, standard regression adjustment is prone to severe bias. In contrast, G-estimation requires less stringent assumptions than path analysis using SEM to unbiasedly estimate the direct effect even in linear settings. In this article, we propose a G-estimation method to estimate the controlled direct effect of treatment on the outcome, by adapting existing G-estimation methods for time-varying treatments without mediators. The proposed method can accommodate continuous and noncontinuous mediators, and requires no models for the confounders. Unbiased estimation only requires correctly specifying a mean model for either the mediator or the outcome. The method is further extended to settings where the mediator or outcome, or both, are latent, and generalizes existing methods for single measurement occasions of the mediator and outcome to longitudinal data on the mediator and outcome. The methods are utilized to assess the effects of an intervention on physical activity that is possibly mediated by motivation to exercise in a randomized study.     

明代大礼议的情礼分歧与论证方法

在明代大礼议中,议礼双方立论基础的不同可以归结为情与礼的分歧。宗法派基于宗法礼制,主张继君统必先继宗统,让皇帝改换父母;人情派基于孝道亲情,主张继统不必继嗣,维护皇帝与父母的亲子关系。双方分别从情、礼出发,主要采用考论史例、诠释经典、探究典章、借助灾异共四种方式论证自己的主张。通过分析大礼议这一生动的道德实践案例,既可以管窥道德情感与道德规范、道德理性的关系,又可以为深化认知、研究利用传统道德资源提供一种可能的途径。
