Learning of syllable-object relations by preverbal infants: The role of temporal synchrony and syllable distinctiveness

The role of temporal synchrony and syllable distinctiveness in preverbal infants’ learning of word-object relations was investigated. In Experiment 1, 7- and 8-month-olds (N = 64) were habituated under conditions where two similar-sounding syllables, /tah/ and /gah/, were spoken simultaneously with the motions of one of two sets of objects (synchronous) or out of phase with the motions (asynchronous). On test trials, 8-month-olds, but not 7-month-olds, showed learning of the relations in the synchronous condition but not in the asynchronous condition. Furthermore, in Experiment 2, following habituation to one of the synchronous syllable-object pairs, 7-month-olds (n = 8) discriminated the syllables and the objects. In Experiment 3, following habituation to two distinct syllables, /tah/-/gih/ or /gah/-/tih/, paired with identical objects, 7-month-olds (n = 40) showed learning of the relations, again only in the synchronous condition. Thus, synchrony, which mothers naturally provide between words and object motions, facilitated the mapping onto objects of similar-sounding syllables at 8 months of age and distinct syllables at 7 months of age. These findings suggest an interaction between infants’ synchrony and syllable distinctiveness perception during early word mapping development.     

Children's ability to distinguish between enjoyment and non‐enjoyment smiles

Children's ability to distinguish between enjoyment and non‐enjoyment smiles was investigated by presenting participants with short video excerpts of smiles. Enjoyment smiles differed from non‐enjoyment smiles by greater symmetry and by appearance changes produced in the eye region by the Cheek Raiser action. The results indicate that 6‐ and 7‐year‐old children have the abilities to detect these differences and are able to interpret them with above chance‐level accuracy. Sensitivity was higher for the symmetry of the smiles than for the appearance changes produced in the eye region and improved in later childhood. Copyright © 2009 John Wiley & Sons, Ltd.     

复合刺激潜意识知觉的属性分离

通过四种复合刺激的属性分离实验,检验刺激不同属性在潜意识知觉中的差异。结果表明,刺激的不同属性在刺激材料潜意识知觉中具有不同的作用。验证了潜意识知觉心理加工的部分优先理论。检验了基于控制迫选任务中比较刺激所建立的复合刺激潜意识知觉属性分离模型的有效性。     

群体断层强度测量指标的构建与检验：一个整合的视角

群体断层概念近些年来在理论和实证研究方面都取得了重要的进展, 但有关断层强度的测量却始终呈现出滞后的态势。已有的文献表明只有FLS, Fau和PMD三个指标对群体断层强度进行了系统而完整的测量, 且三个指标都表现出相当的稳健性。尽管如此, 三大指标却都没有能够反映断层宽度这个重要维度。本研究在以往文献的基础上构建了整合群体断层强度测量指标, 很好地解决了这一问题。整合群体断层强度指标具体表现为亚群体内部一致性、亚群体间差异性和断层宽度的乘积。我们从以往研究中提炼了10个准则对新构建的指标进行了检验, 结果显示, 整合群体断层强度指标要显著优于以往的测度, 10个准则全部能够很好地拟合。本研究最后讨论了基于主观感知的断层强度的测量问题, 并提出了采用回归系数作为衡量亚群体间距离的PMD改进算法。     

受艾滋病影响儿童的歧视知觉在歧视经历和心理健康之间的作用分析

本研究旨在考察中国农村地区受艾滋病影响儿童(包括双孤儿童、单孤儿童和非孤儿童)在经历了父母感染艾滋病、父母因为艾滋病丧亡后的歧视经历和歧视知觉状况,及其对心理健康的影响.采用问卷调查了1221名被试,测查了他们的歧视经历、歧视知觉、心理健康(抑郁、孤独、自尊).经过数据分析发现:(1)歧视经历和歧视知觉存在显著的年龄段和儿童类别的差异,12岁及以下的儿童得分显著高于13岁及以上的,双孤儿童得分显著高于单孤儿童和非孤儿童;抑郁、孤独和自尊存在显著的儿童类别差异,双孤儿童、单孤儿童差于非孤儿童;且孤独和自尊还存在显著的年龄段差异,12岁以下的儿童差于13岁以上的;(2)不同歧视经历和歧视知觉的儿童在抑郁、孤独和自尊上存在显著差异,均是歧视经历、歧视知觉多的儿童抑郁和孤独严重、自尊低;(3)歧视经历对抑郁、孤独和自尊都有显著的预测作用,歧视知觉在其中起到了部分中介作用.     

Psychological Correlates of Support for Compromise: A Polling Study of Jewish-Israeli Attitudes toward Solutions to the Israeli-Palestinian Conflict

A representative national sampling of Israeli Jewish adults (n = 550) reported attitudes toward solutions of the Israeli-Palestinian conflict that were salient in Israeli public discourse in 2002. Negative attitudes toward compromise were associated with zero-sum threat perceptions of the conflict with Palestinians, such that improvement for the Palestinian side can only come at the expense of the Israeli side. Positive attitudes toward compromise were associated with feelings of sympathy toward Palestinians, but, surprisingly, attitudes toward compromise were not associated with feelings of fear toward Palestinians. The possibility is advanced that it is fear of harm to the group, not fear of harm to self and family, that is related to willingness to compromise. Zero-sum perceptions of collective threat were not strongly related to affective reactions, and, contrary to a realist analysis of intergroup conflict, sympathy for Palestinians predicted support for compromise beyond what zero-sum perceptions of threat could predict.     

修饰语的焦点和重音对话语理解的影响

本研究分别采用韵律合适度判断和理解任务,通过两个实验探讨修饰语的焦点和重音之间的关系对话语理解的影响。实验通过操纵答句中的论元是否出现在问句中,变化问句的信息状态;通过操纵答句的不同句子成份重读,变化答句的重读位置。实验结果发现：新的修饰语重读,旧的修饰语不重读;修饰语不投射焦点,即修饰语重读不将焦点投射到修饰语的中心语上。     

印象管理对组织公民行为的预测作用的实证研究

以188名企业员工及其主管和同事为被试,运用问卷调查法和分层回归分析的统计方法考察了印象管理独立于组织公平感对组织公民行为的预测作用。结果发现：在控制了公平感之后,印象管理能够显著增加大多数主管评价OCB可解释的变异,但与任何同事评价OCB之间不存在显著相关。结论：印象管理对除OCB—S以外的主管评价OCB具有显著的独立预测作用。     

仁与天理通而为一视域下的程颢易学

置身由汉唐经学向宋明理学转型过程中的程颢,对易学的天人之学作出了创造性诠释与转化,建构起仁与天理通而为一视域下的崭新易学天人之学,推出了他的理学体系。程颢的易学,首先开示了一个充满盎然生机、生意的有机整体宇宙图景,继之揭示了此一生机、生意之所自来的终极宇宙根基、根据,即天理,并指出天理是一终极的令物生生之理,即是一最高的绝对之善本身,由此天理即仁体。天理与仁通而为一,可名之日天理—仁体。此一天理—仁体令天地万物涵具并彰显出盎然生机、生意,且一体无隔。人禀受它而具备了存在的所以然的终极宇宙根基和充足的价值根据与资源,应据之一则珍视自己生命的内在价值,令其原发性畅然舒展、展现与实现,再则珍视并善待他人他物的内在价值,视天地人物一体无隔的有机宇宙整体中的一切皆为我生命的有机组成部分,期其亦皆能原发性畅然舒展、展现与实现自我,从而成就起一宇宙式大我,达到成为天理—仁体自觉圆融化身的最高的生命境界,即天地境界。为此,尚需作识仁与定性的工夫。
