Blind ethics: Closing one's eyes polarizes moral judgments and discourages dishonest behavior

Four experiments demonstrate that closing one’s eyes affects ethical judgment and behavior because it induces people to mentally simulate events more extensively. People who considered situations with their eyes closed rather than open judged immoral behaviors as more unethical and moral behaviors as more ethical. In addition, considering potential decisions with closed eyes decreased stated intentions to behave ethically and actual self-interested behavior. This relationship was mediated by the more extensive mental simulation that occurred with eyes closed rather than open, which, in turn, intensified emotional reactions to the ethical situation. We discuss the implications of these findings for moral psychology and ethical decision making.     

Facial Expressions and the Ability to Recognize Emotions from the Eyes or Mouth: A Comparison Between Children and Adults

The authors sought to contribute to the literature on the ability to recognize anger, happiness, fear, surprise, sadness, disgust, and neutral emotions from facial information. They aimed to investigate if—regardless of age—this pattern changes. More specifically, the present study aimed to compare the difference between the performance of adults and 6- to 7-year-old children in detecting emotions from the whole face and a specific face region, namely the eyes and mouth. The findings seem to indicate that, for both groups, recognizing disgust, happiness, and surprise is facilitated when pictures represent the whole face. However, with regard to a specific region, a prevalence for children was not found between the eyes and mouth. Meanwhile, for adults, would seem to detect a greater role of the eye region. Finally, regarding the differences in the performance of emotions recognition, adults are better only in a few cases, whereas children are better in recognizing anger from the mouth.     

亲社会行为中的“眼睛效应”

呈现眼睛图片就会使人们的行为发生变化即眼睛效应(the watching eyes effect)。名誉机制和规则心理可以解释眼睛效应,但尚未得出一致的结论。虽然大量研究证明亲社会行为中存在眼睛效应,但任务类型、实验情境、暴露时间、匿名性等客观环境以及被试的群体成员身份和个性特征等因素都会影响眼睛效应的发生及其强度。未来研究可以从具身认知的视角深入探讨眼睛效应的进化心理机制,开展眼睛效应的跨文化研究,探讨其背后的脑神经机制,并扩展眼睛效应的应用型研究。     

眼睛注视线索提示效应: 内源性注意还是外源性注意?

采用改进的Posner视-空间线索提示范式, 对眼睛注视线索提示效应(eyes gaze cueing effect)的加工机制进行了探讨。实验一考察注视提示线索对空间Stroop效应的影响; 实验二考察注视提示线索对特征抽取和特征整合的影响。实验结果显示: 注视线索提示有效时的空间Stroop效应显著大于提示无效的情景; 在单一特征搜索与特征联合搜索任务中, 注视线索提示效应无差别。这说明, 注视线索通过在头脑里形成空间方位表征诱导注意转移; 注视线索通过影响特征抽取、而非特征整合阶段, 对客体加工产生易化。本研究支持注视线索提示效应属于内源性注意的观点。     

Yang's iris illusion: External contour causes length‐assimilation illusions1

The Delboeuf illusion and the Ebbinghaus illusion (also known as the Titchener illusion) demonstrate that an external contour can lead to size‐assimilation and size‐contrast perception. This paper explores a novel illusion, revealing that neighboring external contours can also lead to a distortion in length perception. The illusion was originally discovered from a face stimulus (Experiment 1) in which a face was depicted alongside its mirror image so as to make the four irises absolutely equidistant. The distance between the middle two irises was underestimated in Asian faces, but overestimated in Caucasian faces. The illusion was also maintained when the facial stimuli were replaced by line drawings of eyes (Experiment 2). However, the illusion vanished when the irises were presented alone. Further scrutiny of the differences in facial characteristics between Asian and Caucasian faces reveals that the illusion might be elicited by the relative position of the eye shapes. This hypothesis was confirmed in Experiment 3, in which the distances between the eye shapes and the irises were manipulated.     

Referential cohesion and logical coherence of narration after closed head injury

A group with closed head injury was compared to neurologically intact controls regarding the referential cohesion and logical coherence of narrative production. A sample of six stories was obtained with tasks of cartoon-elicited story-telling and auditory-oral retelling. We found deficits in the clinical group with respect to referential cohesion, logical coherence, and accuracy of narration. The occurrence of deficits depended on the condition of narrative production and, to some extent, on the particular story used. The primary implications of this study pertain to the attention given by researchers to the feature of discourse production being studied and processing demands of the task.     

Do the laws of physics forbid the operation of time machines?

We address the question of whether it is possible to operate a time machine by manipulating matter and energy so as to manufacture closed timelike curves. This question has received a great deal of attention in the physics literature, with attempts to prove no-go theorems based on classical general relativity and various hybrid theories serving as steps along the way towards quantum gravity. Despite the effort put into these no-go theorems, there is no widely accepted definition of a time machine. We explain the conundrum that must be faced in providing a satisfactory definition and propose a resolution. Roughly, we require that all extensions of the time machine region contain closed timelike curves; the actions of the time machine operator are then sufficiently “potent” to guarantee that closed timelike curves appear. We then review no-go theorems based on classical general relativity, semi-classical quantum gravity, quantum field theory on curved spacetime, and Euclidean quantum gravity. Our verdict on the question of our title is that no result of sufficient generality to underwrite a confident “yes” has been proven. Our review of the no-go results does, however, highlight several foundational problems at the intersection of general relativity and quantum physics that lend substance to the search for an answer.     

合作行为中的“眼睛效应”:解释机制与限制因素

呈现眼睛特征的图片就能使人的行为发生变化的现象称为眼睛效应。眼睛效应存在于多种社会现象中, 合作行为中的眼睛效应已被多种实验证明, 其原理可从声誉机制、规则机制、奖惩机制及认知机制等视角予以解释。眼睛效应的发生受在场他人、任务类型、个体公众意识及群体身份、线索呈现方式等因素的限制。目前有关眼睛效应的稳定性仍存在较多争议, 未来需要从性别和文化等个体或群体差异、脑生理机制、社会应用价值等方面进行深入研究。     

Applying Chaos Theory to Careers: Attraction and attractors

This article presents the Chaos Theory of Careers with particular reference to the concepts of “attraction” and “attractors”. Attractors are defined in terms of characteristic trajectories, feedback mechanisms, end states, ordered boundedness, reality visions and equilibrium and fluctuation. The identified types of attractors (point, pendulum, torus and strange) and their relevance to career development are described. The attractor concept is then applied to major barriers in career development and life transition by a consideration of closed and open systems thinking. It is contended that ultimately the context of human experience is an open system and that career development difficulties arise when closed systems thinking is used in an open systems reality. The practical counseling applications and counseling research evidence using attractors are briefly reviewed. The additional potential contributions of the Chaos Theory of Careers to the career development field are also outlined.     

The production of determiners: evidence from French.

In numerous languages determiner forms depend not only on semantic information but also on several other kinds of information, such as the grammatical gender of the controlling noun or the phonological properties of the context. In the present research we contrasted two possible accounts of determiner retrieval: one in which every type of required information is bundled into a unitized representation for determiner retrieval and one in which each type of information can individually activate determiner forms. These alternative hypotheses were investigated in three experiments in which native speakers of French named pictures with simple [determiner + noun] or complex [determiner + adjective + noun] noun phrases. In the experiments, the properties of the contextual cues that drive the retrieval of the determiner were manipulated - for example, we manipulated the number of determiner forms that are compatible with a given grammatical gender and the number of grammatical genders that a given determiner form can be used with. Neither hypothesis can fully account for the results of the three experiments. However, a hybrid hypothesis that combines the principal features of the two hypotheses provides a good account of the data.
