Social cues in animated conversational agents

In human‐computer interaction people often interpret the interaction with the computer as interactions with humans. The social agency theory suggests that social cues like the face and voice of the agent motivate this interpretation. In two off‐line experiments in which comprehension scores and liking ratings were collected, we found that participants preferred natural agents with natural voices, as predicted by the social‐cue hypothesis. Although female agents with male voices formed an exception, this was explained by a stereotype effect. These findings support the social‐cue hypothesis and the social agency theory that human characteristics are applied in the perception of computational animated conversational agents.

儒家的"和"伦理

儒家伦理重视和谐,有着丰富的“和”资源。它的“和”有三层含义:作为道德品质的“和”、作为道德本体的“中和”、作为世界本体的“太和”。儒家“和”的世界图景为“万物并育而不相害,道并行而不相悖”的“太和”景象。儒家实现“和”的手段主要是“礼”,其具体要求是“明分”、“安分”、“尽伦尽责”、“中节”等。儒家的“和”伦理的这些资源对我们今天和谐社会的建构仍有积极意义。     

青海大学生创造性思维及其相关因素研究

本文采用创造性思维问卷、推理能力测验问卷和Y—G量表对青海省四所高校的548名大学生的创造性思维及其相关因素进行研究。结果显示：(1)青海省大学生发散性思维三个特征的发展水平与青海省的经济发展和教育条件与水平密切关联。(2)创造性思维是逻辑和非逻辑思维有机结合。(3)学科性质不同、上大学起点不同对大学生创造性思维的发展有着重要影响。(4)推理能力与语词创造性的发展密切联系,但与图形创造性无显著性相关。(5)性格特征通过认知方式对创造性思维产生影响。     

儿童道德情绪归因研究的进展及未来展望

20世纪70年代以来,对儿童道德情绪归因的研究主要集中在概念界定、定向发展、年龄差异、产生原因及其影响因素等方面。但在研究对象的拓展、情境的设置以及归因对象的完善等方面还需要未来作进一步的探索与研究。     

小学低年级学生对陌生形声字的语音提取

对小学低年级学生对陌生形声字的语音提取进行了研究。实验1表明,字频、声旁位置、声旁与整字音段的关系影响小学二年级学生对陌生形声字的语音提取。高频字的命名成绩好于低频字,声旁在右的形声字命名成绩好于声旁在左的形声字,声旁与整字音段相同的形声字命名成绩好于声旁与整字音段部分相同或完全不同的形声字,体现了“规则效应”。语文水平也影响被试对陌生形声字的语音提取。小学生对左右结构的陌生形声字的语音提取策略按使用频率依次为：读半边、部件重组、整字形似、部件形似、词汇联拼、部件意义联想、整字意义联想、部件词汇联拼。实验2结果表明,当陌生形声字的形旁不可命名时,小学一年级学生对整字的命名更倾向于利用声旁信息。形声字声旁在右时,利用可单独命名的声旁命名整字的可能性更大。当形旁可命名时．声旁的语音线索与形旁的语音线索存在竞争。

Dual scaling of comparison and reference stimuli in multi-dimensional psychological space

Dzhafarov and Colonius (Psychol. Bull. Rev. 6 (1999)239; J. Math. Psychol. 45(2001)670) proposed a theory of Fechnerian scaling of the stimulus space based on the psychometric (discrimination probability) function of a human subject in a same-different comparison task. Here, we investigate a related but different paradigm, namely, referent-probe comparison task, in which the pair of stimuli (x and y) under comparison assumes substantively different psychological status, one serving as a referent and the other as a probe. The duality between a pair of psychometric functions, arising from assigning either x or y to be the fixed reference stimulus and the other to be the varying comparison stimulus, and the 1-to-1 mapping between the two stimulus spaces X and Y under either assignment are analyzed. Following Dzhafarov and Colonius, we investigate two properties characteristic of a referent-probe comparison task, namely, (i) Regular cross-minimality—for the pair of stimulus values involved in referent-probe comparison, each minimizes a discrimination probability function where the other is treated as the fixed reference stimulus; (ii) Nonconstant self-similarity—the value of the discrimination probability function at its minima is a nonconstant function of the reference stimulus value. For the particular form of psychometric functions investigated, it is shown that imposing the condition of regular cross-minimality on the pair of psychometric functions forces a consistent (but otherwise still arbitrary) mapping between X and Y, such that it is independent of the assignment of reference/comparison status to x and to y. The resulting psychometric differentials under both assignments are equal, and take an asymmetric, dualistic form reminiscent of the so-called divergence measure that appeared in the context of differential geometry of the probability manifold with dually flat connections (Differential Geometric Methods in Statistics, Lecture Notes in Statistics, Vol. 28, Springer, New York, 1985). The pair of divergence functions on X and on Y, respectively, induce a Riemannian metric in the small, with psychometric order (defined in Dzhafarov & Colonius, 1999) equal to 2. The difference between the Finsler-Riemann geometric approach to the stimulus space (Dzhafarov & Colonius, 1999) and this dually-affine Riemannian geometric approach to the dual scaling of the comparison and the reference stimuli is discussed.     

Simple and Joint Effects of Gender and Self-Esteem on Responses to Same-Sex Sexual Harassment

In a sample of 431 white-collar professionals, we examined the impact of gender and self-esteem on individuals' intentions to seek legal counsel, confront the harasser, and make formal reports within the organization in response to approach-based same-sex sexual harassment. We hypothesized that gender, self-esteem, and their interaction would be related to assertive responses. All three hypotheses received support: men were more likely than women to respond assertively; self-esteem was positively related to response intentions; and self-esteem had a greater impact on men's responses than on women's responses. These results suggest that frameworks used to describe responses to cross-sex sexual harassment may not be adequate for same-sex sexual harassment. Post hoc analyses revealed that perceiving the behavior as harassment mediated the relationship between self-esteem and the responses to harassment, but did not mediate the relationships between gender and the responses to harassment. These findings contribute to the research on acknowledging sexual harassment.
