正立和倒立的威胁性身体表情的识别

为探索身体表情的加工时程以及加工方式是否为构形加工,采用ERP技术考察对正立和倒立的威胁性身体表情（恐惧和愤怒）的识别。行为结果发现倒置效应存在。ERP结果发现：早期阶段已有对威胁性情绪（P1）和倒置效应（N1）的加工;中期阶段主要存在对倒置效应的加工（N170）;晚期阶段,威胁性情绪在正立条件上得到更多的加工（P3和LPP）。结果表明,威胁性身体表情加工有独特的时间进程,加工方式以构形加工为主。     

视觉与听觉情绪信息关系判断中的交互作用

通过要求被试判断同时呈现的视听信息情绪效价的关系,考察视听情绪信息整合加工特点。实验一中词汇效价与韵律效价不冲突,实验二中词汇效价与韵律效价冲突。两个实验一致发现当面孔表情为积极时,被试对视听通道情绪信息关系判断更准确;实验二还发现,当面孔表情为消极时,相对于韵律线索,被试根据语义线索对视听信息关系判断更迅速。上述结果说明视听信息在同时呈现时,视觉信息可能先行加工,并影响到随后有关视听关系的加工。     

去焦点化提升体验幸福的积极意义及心理机制

去焦点化是指通过操纵个体对焦点以外的非焦点事件或因素的关注, 从而减少焦点事件对个体认知判断和情绪影响的一种策略。如何利用去焦点化减少聚焦错觉对体验幸福所造成的消极影响, 提升体验幸福, 是积极心理学关注的热点。研究发现, 可以通过去焦点化策略, 减少个体对不同类型消极情绪的聚焦错觉, 以达到提升体验幸福的目的。其心理机制可从注意分散假设和情感加工理论进行解释。未来研究可进一步关注: (1)一般去焦点化与自我相关去焦点化的比较与探讨; (2)去焦点化对后续体验幸福的影响; (3)重新聚焦对个体体验幸福的影响。     

人类疼痛表情研究进展

疼痛表情是人类疼痛表达的行为方式之一,具有重要的生存适应和社会交流价值。疼痛表情研究应当遵循行为观察方法,基于面部运动编码系统（Facial Action Coding System, FACS）的表情编码有助于疼痛表情的量化分析。年龄、性别、社会因素、文化背景等多种因素会影响疼痛表情表达,使疼痛表情在不同个体之间表现出共性和个性并存的特性。在不断改进研究方法的基础上,未来可对疼痛表情的生理心理机制作出更多阐述,并有望建立完备的人类疼痛表情信息库。     

The effect of laughter expression modulation on emotional experience in 4 to 10 year-old children

According to the literature, in adulthood, facial expression control unconsciously generates a congruent change in emotional experience (facial feedback). Although only a few studies have been conducted on this phenomenon with children, it is to be expected that the strength of the link between facial expression and emotional experience will diminish with age, and consequently, that the facial feedback effect will decrease with age. In order to test this hypothesis, we used an emotional induction paradigm (based on funny video-clips) with an expressive change paradigm (i.e., free expression vs. laughter restriction vs. laughter exaggeration). The emotional experience of 4–10-year-old children was assessed a posteriori based on analyses of their narratives about the video-clips. Results indicated that the children benefited from a facial feedback effect on their emotional experiences without an age effect. They are discussed in the light of the literature on emotional regulation and emotional development.     

情绪识别研究中被“冷落”的线索:躯体表情加工的特点、神经基础及加工机制

躯体和面孔是个体情绪表达与识别的重要线索。与面部表情相比,躯体表情加工的显著特点是补偿情绪信息,感知运动与行为信息,及产生适应性行为。情绪躯体与面孔加工的神经基础可能相邻或部分重合,但也存在分离;EBA、FBA、SPL、IPL等是与躯体表情加工相关的特异性脑区。今后应系统研究面孔、躯体及语音情绪线索加工潜在的神经基础,探讨躯体情绪加工的跨文化差异,考察情绪障碍患者的躯体表情加工特点。     

Two Kinds of Brain Injury in Sport

Abstract

After years of skepticism and denials regarding the significance of concussions in sport, the issue is now front and center. This is fitting, given that the impact of concussions in sport is profound. Thus, it is with trepidation that one ventures to direct some attention onto brain injuries other than concussions incurred through sport. Given a closer look, however, it may be that considering various kinds of brain injuries, with different causes, will help us better understand the range and seriousness of brain injuries in sport. My focus is on emotional trauma in sport. I argue that severe emotional pathology is evidence of underlying brain injury. Any attempt to minimize the significance of emotional disturbance that results from emotional trauma as ‘merely’ psychological in nature is thus misguided.     

The contribution of facial regions to judgements of happiness and trustworthiness from dynamic expressions

What expressive facial features and processing mechanisms make a person look trustworthy, relative to happy? Participants judged the un/happiness or un/trustworthiness of people with dynamic expressions in which the eyes and/or the mouth unfolded from neutral to happy or vice versa. Faces with an unfolding smile looked more trustworthy and happier than faces with a neutral mouth, regardless of the eye expression. Unfolding happy eyes increased both trustworthiness and happiness only in the presence of a congruent unfolding smiling mouth. Nevertheless, the contribution of the mouth was greater for happiness than for trustworthiness; and the mouth was especially visually salient for expressions favouring happiness more than trustworthiness. We conclude that the categorisation of facial happiness is more automatically driven by the visual saliency of a single feature, that is, the smiling mouth, while perception of trustworthiness is more strategic, with the eyes being necessarily incorporated into a configural face representation.     

Effects of the emotional properties of words and a manipulation of mindset on performance of an ambiguous task

In this study, we investigated whether processing of an ambiguous task was influenced by the emotional properties of words or promotion of a specific mindset. Words used differed in valence and origin of an affective state (derived “from heart” or “from mind”). Mindset was manipulated by suggesting that either fast or slow performance was associated with cleverness and then having participants perform a task requiring the “smart” processing strategy. The ambiguous task was to choose which of 2 Far East hexagrams better represented a previously presented target word. Reaction latencies were measured and appeared to be longer for ambiguous task probes involving words of reflective origin rather than automatic or unspecified origin. Promotion of heuristic thinking was associated with shorter responses latencies than promotion of systematic or neutral processing. The study demonstrated that the processing mode may be promoted by means of both emotional and cognitive manipulations and each of them is working in a specific way.     

儿童对父母关爱的感知能力的发展

为了说明儿童能否感知到父母在情感、生理和行为三个方面的关爱,研究采用情境故事考察了幼儿园中班及小学二、四、六年级169名儿童对父母关爱的感知能力的发展特点。结果表明：随着年龄的增长,儿童对父母关爱的感知能力在不断发展;女孩对父母情感关爱的感知显著高于男孩;独生子女对父母生理关爱的感知显著高于非独生子女;高同伴接纳水平儿童对父母生理关爱的感知显著高于低同伴接纳水平儿童。
