Sex Related Factors in the Perception of Threatening Facial Expressions

This study replicated and extended previously reported sex differences involving both viewer and target in the recognition of threatening facial expressions. Based on the assumption that the evolved cognitive mechanisms mediating anger recognition would have been designed by natural selection to operate quickly in the interests of survival, brief tachistoscopic presentation of stimulus photographs was used. Additionally, in contrast to prior published studies, the statistical methods of signal detection research were used to control for the confounding effects of non-random guessing. The main hypothesis, that anger posed by males would be more accurately perceived than anger posed by females, was supported. A secondary hypothesis, that female-posed anger would be more accurately perceived by women than by men, received partial support. Testosterone levels, measured inferentially in terms of diurnal cycles, failed to show the hypothesized positive relationship to accuracy of anger perception.     

浅析汉语中表因果关系句子的英译法

由于英汉两种语言的差异,汉语中表因果关系的句子翻译成英文有不同的译法,除了采用原因状语从句的结构,还可以采用时间状语从句、地点状语从句、定语从句、不定式短语、介词短语、独立主格结构等多种不同的表达方式。     

类型电影与观众态度

根据电影叙事是否依据一个形式惯例传统,电影理论把电影分为类型电影和非类型电影。事实上,来自于既有惯例的类型经验影响着我们从日常生活到艺术欣赏很多行为中所具有的心理模式,我们的相关态度在很大程度上也以此建立。本文讨论的是在观看类型电影的时候观众的欣赏态度,并将这个态度分为"作为基础的惯例经验"、"欣赏时建构的心理时空"和"态度的娱乐指向"三个部分,从中可以看到三个部分的相互关系和观众欣赏类型电影的心理特征。

On the logic of common belief and common knowledge

The paper surveys the currently available axiomatizations of common belief (CB) and common knowledge (CK) by means of modal propositional logics. (Throughout, knowledge — whether individual or common — is defined as true belief.) Section 1 introduces the formal method of axiomatization followed by epistemic logicians, especially the syntax-semantics distinction, and the notion of a soundness and completeness theorem. Section 2 explains the syntactical concepts, while briefly discussing their motivations. Two standard semantic constructions, Kripke structures and neighbourhood structures, are introduced in Sections 3 and 4, respectively. It is recalled that Aumann's partitional model of CK is a particular case of a definition in terms of Kripke structures. The paper also restates the well-known fact that Kripke structures can be regarded as particular cases of neighbourhood structures. Section 3 reviews the soundness and completeness theorems proved w.r.t. the former structures by Fagin, Halpern, Moses and Vardi, as well as related results by Lismont. Section 4 reviews the corresponding theorems derived w.r.t. the latter structures by Lismont and Mongin. A general conclusion of the paper is that the axiomatization of CB does not require as strong systems of individual belief as was originally thought — onlymonotonicity has thusfar proved indispensable. Section 5 explains another consequence of general relevance: despite the infinitary nature of CB, the axiom systems of this paper admit of effective decision procedures, i.e., they aredecidable in the logician's sense.     

“Facing” leaders: Facial expression and leadership perception

This experimental study investigated the effect of a leader's expression of happy versus nervous emotions on subsequent perceptions of leadership and ratings of traits associated with implicit leadership theories (ILTs). Being fast and universally understood, emotions are ideal stimuli for investigating the dynamic effects of ILTs, which were understood in this study in terms of the constraints that expressed emotions impose on the connectionist networks that activate ILTs. The experimental design contrasted videotaped and still frame presentations of a leadership event; however, this methodological factor had no significant effects and analyses were thus collapsed across this factor. Key findings were that the expression of a happy versus nervous emotion at the end of a problem-solving sequence had multiple effects: happy emotions resulted in higher leadership ratings, higher trait ratings, greater correlations among trait ratings, and greater dependence of trait ratings on leadership perceptions. An exploratory model suggested that leadership impressions mediated the effects of facial emotions on trait ratings. The discussion further links the study findings with interpretations in terms of ILTs and many types of constraints on these cognitive structures. It also suggests ways to integrate these ideas with advances in neuroscience research.     

It's written all over their faces: Preschoolers' emotion understanding

Emotion understanding is a multifaceted construct made up of several components. To identify how several common components of emotion understanding relate to one another, five emotion understanding tasks were compared within the same group of children. Fifty‐four preschool children (M = 3.81 years, SD = 0.40) were asked to display the typical facial expression of six emotions after hearing their corresponding emotion label. They were then read six vignettes and asked to: “use your face to show how [the protagonist] would feel,” provide an emotion label for the main character, and “choose a picture of a face that would look like [the main character].” Finally, they were asked to provide a label for emotions presented to them in photographs. For all tasks, six emotions were examined: happiness, sadness, anger, fear, surprise, and disgust. With the exception of the two modeling tasks, results show correlations among the emotion understanding tasks. There was a significant interaction between task and emotion category for emotion understanding accuracy. However, there was some consistency in the pattern of discrete emotion categorization emergence across the tasks. Additionally, accuracy scores (representing emotion understanding) across tasks were not equivalent. Findings are discussed in the broader context of emotion understanding.     

胡塞尔“本质机遇性的表述”探析

在胡塞尔的《逻辑研究》中,表述处于对指示的区别与对直观充实的准备这个中介地位上,而其中本质机遇性的表述更有着特殊的性质。为了解释这些特殊性,就需要规定其内在的含义结构与功能关系。而在德里达看来,这反映了胡塞尔的在场形而上学立场。
