面孔线索对4~6岁幼儿真人与卡通面孔记忆的影响

对真人面孔与卡通面孔记忆线索的比较研究,有助于深入认识儿童的面孔认知机制。采用“学习-再认”范式,以内部线索面孔、外部线索面孔和完整面孔为刺激材料,探究面孔线索对4~6岁幼儿真人与卡通面孔记忆的影响。结果发现：（1）女童对真人面孔的记忆显著优于卡通;（2）对卡通面孔的记忆,男童显著优于女童;（3）对真人面孔：完整面孔记忆显著优于内部线索面孔与外部线索面孔;对卡通面孔：外部线索面孔记忆最佳,其次完整面孔,内部线索面孔最低;（4）幼儿对外部与内部线索面孔的记忆能力随年龄逐步提高,6岁显著优于4岁。综上,幼儿对真人面孔与卡通面孔的记忆模式存在差异;且面孔类别、性别、面孔线索与年龄等因素均影响幼儿的面孔记忆。     

5~6岁幼儿对不同文化背景卡通面孔再认的眼动研究

采用不同文化背景卡通面孔为刺激材料,探究中国幼儿对中国风、日本风与欧美风女性卡通面孔再认的差异及其眼动机制。结果显示：（1）卡通面孔再认正确率差异显著,日本风面孔具有记忆优势;女童对三种面孔再认正确率均显著高于男童;（2）卡通面孔特质中的夸张性对卡通面孔再认正确率的预测显著;（3）文化背景与性别因素显著影响平均注视时间、注视点个数、眼跳次数和幅度及瞳孔大小等总体眼动指标;（4）兴趣区数据显示：对日本风面孔的总注视时间和注视点个数最高;卡通面孔再认主要依赖于眼部、其次为鼻子;文化背景与兴趣区存在交互作用,在注视时间、注视点个数与首注视点指标上,提示幼儿更关注日本风的眼睛区域与欧美风的鼻子区域。综上,幼儿对不同文化背景卡通面孔的记忆和眼动加工存在差异,日本风卡通面孔的记忆优势可能基于其夸张性高的面孔特质,尤其在眼睛部位;行为学与眼动指标均提示女童对卡通面孔的再认具有优势。     

不同任务情境中5~6岁儿童卡通面孔加工的眼动研究

以卡通面孔图片为刺激材料,赋予5~6岁儿童三种不同的加工任务,包括卡通面孔识别、分类和吸引力评价,旨在比较其在不同任务情境中的眼动差异。结果表明:(1)任务情境会影响儿童对卡通面孔的加工。在不同的面孔加工任务中,儿童的反应时、正确率、注视时间和次数等存在差异;(2)随着三种任务难度的逐渐加大,儿童的加工程度也相应地加深;(3)儿童在三种任务中的加工方式一致,对面部不同部位的关注程度不同:加工初期特别关注鼻子,而后眼睛部位耗费最多的注意资源,其次是鼻子、嘴巴、前额和脸颊,极少关注下巴;(4)男女童在卡通面孔分类任务中表现出较显著的性别差异,女童具有速度方面的优势,而男童对于关键信息的搜索则更为积极主动。     

情绪效价与面孔类型对幼儿无意视盲的影响

幼儿对不同的情绪面孔图片存在不同的注意偏向,考察情绪效价与面孔类型对幼儿无意视盲的影响,可以帮助我们进一步认识幼儿对情绪面孔的注意偏向。本研究采用静态无意视盲的实验范式,通过2（面孔类型：符号化卡通、真人）×2（情绪效价：积极、消极）被试间完全随机设计,考察了111名幼儿（62.5±3.6个月,男生60名）在无意注意条件下对不同情绪效价和不同类型面孔的觉察情况。结果表明：（1）幼儿对积极情绪面孔的觉察率显著高于消极情绪面孔;（2）符号化卡通面孔与真人面孔的整体觉察率不存在显著差异;（3）积极情绪面孔中符号化卡通面孔的觉察率高于真人面孔。综上,情绪效价对无意视盲的影响会基于面孔类型的不同而不同,幼儿对卡通积极情绪面孔有更显著的注意偏向。

成人与幼儿面部表情注意偏好的眼动研究

本研究选取45名3-5岁幼儿和39名大学本科生作为被试。实验材料为恐惧、愤怒、悲伤、惊讶和高兴五种面部表情图片。用Tobbi眼动仪记录被试观察表情图片时的眼动轨迹。结果发现：（1）成人偏好高兴表情,并在高兴表情上的注视时间和次数显著大于幼儿;（2）成人偏好注视眼部,幼儿偏好注视嘴部。结果表明,面部表情注意偏好的发展具有社会依存性,趋向于偏好积极情绪,这种发展变化与面部表情部位的注意偏好相关。     

新生儿面孔识别中的两种偏好现象

面孔偏好和吸引力偏好是新生儿（0~1个月）面孔识别中两种重要的偏好现象。面孔偏好（face preference）是指呈现面孔和非面孔刺激时个体偏好面孔的现象;吸引力偏好（attractiveness preference）是指呈现面孔刺激时个体偏好有吸引力面孔的现象。文章从行为研究和原因探析两个方面对新生儿面孔偏好和吸引力偏好的研究概况进行了介绍,认为主体、客体、环境三方面都在不同程度上影响着新生儿的面孔识别行为,指出未来的研究还应在实验对象、实验材料等方面进一步努力。     

面孔吸引力观察者参照:“角度效应”的眼动研究

以标准的黑白面孔图片作为实验材料,让41名大学生观看不同倾斜角度(左倾、竖直和右倾)的面孔图片,并对之进行面孔吸引力的评价,同时用眼动仪记录被试的眼动数据。结果显示:(1)被试观看左倾和右倾面孔的平均瞳孔大小显著小于观看竖直面孔的平均瞳孔大小,观看左倾面孔的平均瞳孔大小显著大于右倾面孔;(2)被试对左倾和右倾面孔的平均注视时间显著短于对竖直面孔的平均注视时间,同时对左倾面孔的注视时间显著长于右倾面孔;(3)被试对左倾和右倾面孔的平均注视次数显著少于对竖直面孔的平均注视次数。实验结果表明,面孔的倾斜角度很可能是影响面孔吸引力的一个重要因素,在面孔吸引力的审美偏好中存在"角度效应",即竖直面孔的吸引力高于倾斜面孔的吸引力,左倾面孔的吸引力高于右倾面孔的吸引力。     

男性化与女性化对面孔偏好的影响—— 基于图像处理技术和眼动的检验

采用图像处理技术和眼动探讨了性别二态线索对面孔偏好的影响。实验1发现非面孔线索未掩蔽和掩蔽时, 感知男性化技术与原始照片条件下女性化的男性面孔更有吸引力和信任度; 性别二态技术条件下, 非面孔线索未掩蔽时男性化的男性面孔更有吸引力和信任度。实验2表明被试对男性面孔的平均瞳孔大小和注视次数均大于和多于女性面孔, 首次注视时间短于女性面孔; 被试对男性化面孔的首次注视时间和首次注视持续时间均长于女性化面孔。     

背景性质对7-10岁自闭症谱系障碍儿童面孔搜索与加工的作用

为了考察背景性质对ASD者搜索面孔的影响,设计两个眼动实验任务,要求14名7~10岁ASD儿童和20名同年龄正常儿童观看图片。实验一采用将面孔嵌入风景图片中引起语义不一致的刺激;实验二采用含有面孔的无意义背景乱序图片刺激。结果发现：（1）面孔与背景语义不一致并不能促进ASD儿童对面孔的搜索;（2）乱序背景对ASD儿童面孔搜索与加工没有产生干扰作用,但使正常儿童的搜索时间变长;（3）一旦觉察到面孔后,ASD儿童对面孔的注视时间少于正常儿童。表明正常儿童对面孔的搜索与加工受背景性质的影响,而ASD儿童不受背景性质的影响;一旦发现面孔,ASD儿童的注意维持较短,但面孔加工模式与正常儿童相似。     

Attractiveness as a Function of Skin Tone and Facial Features: Evidence from Categorization Studies

Participants rated the attractiveness and racial typicality of male faces varying in their facial features from Afrocentric to Eurocentric and in skin tone from dark to light in two experiments. Experiment 1 provided evidence that facial features and skin tone have an interactive effect on perceptions of attractiveness and mixed-race faces are perceived as more attractive than single-race faces. Experiment 2 further confirmed that faces with medium levels of skin tone and facial features are perceived as more attractive than faces with extreme levels of these factors. Black phenotypes (combinations of dark skin tone and Afrocentric facial features) were rated as more attractive than White phenotypes (combinations of light skin tone and Eurocentric facial features); ambiguous faces (combinations of Afrocentric and Eurocentric physiognomy) with medium levels of skin tone were rated as the most attractive in Experiment 2. Perceptions of attractiveness were relatively independent of racial categorization in both experiments.     

面孔吸引力的整体表征及其动态性增强

面孔作为一种高级的视觉刺激,在人际交往中有着无可替代的作用。其中,面孔吸引力更是影响着日常生活的重要社交决策,如择偶、交友、求职、社会交换等。长久以来,研究者们从面孔特征、社会信息和观察者因素等角度不断探索着人们对静态面孔吸引力的感知,且多从进化角度加以解释。但是,人们如何表征面孔吸引力以及其动态性增强机制仍未可知。本项目通过两个研究,分别从面孔吸引力的整体表征,以及面孔动态性通过影响整体加工、影响对整体信息和特征信息的注意、以及影响社会信息来增强吸引力,从这两个角度尝试回答这一问题。在研究1中,本项目从整体加工的角度探索了面孔吸引力的认知表征。研究1.1通过评分任务和适应范式探索高空间频率（更多局部特征）和低空间频率（更多整体特征）对面孔吸引力的影响,旨在从空间频率探讨面孔吸引力的整体表征。研究1.2通过操纵面孔对称性和面孔常态性探索面孔常态性在面孔对称性和面孔吸引力间的中介作用,探讨面孔吸引力的常态构型表征。研究1.3引入“三庭五眼”这一中国传统面孔审美理论,通过评分任务和适应范式研究“三庭五眼” 构型是否符合中国人对高吸引力中国面孔的表征,以此探讨面孔吸引力的整体表征。研究1.4通过评分任务和适应范式考察局部面孔遮挡是否促进整体面孔吸引力,以及这种促进作用是否由于人们通过局部特征“脑补”出了完整面孔。研究2从整体加工、注意和生命力的角度探讨面孔吸引力的动态性增强机制。研究2.1使用合成效应范式测量动态面孔吸引力的整体加工,探索动静态面孔的吸引力差异是否源于其整体加工程度的不同。研究2.2使用注意分散范式,并结合眼动技术,探讨人们对动静态面孔的注视模式是否存在差异,这种差异是否能解释动态面孔吸引力的增强。研究2.3结合问卷法、实验法和结构方程模型,考察了生命力这一社会因素对动静态面孔吸引力的影响。本项目探讨了面孔吸引力的认知表征以及其动态性增强机制,有助于我们进一步理解人们对面孔吸引力的认知加工以及人类欣赏美这一高级智能。同时,本项目的结果对于日常人际交往和面孔吸引力相关算法的优化等方面也有潜在的应用价值。     

面孔吸引力和信息正确性对幼儿选择性信任的影响

实验1采用3×2×2 的混合设计, 考察4~6岁幼儿获取全新信息时基于面孔吸引力的选择性信任及其特点。结果显示：(1) 4~6岁的男孩和女孩均表现出对高面孔吸引力者的选择性信任。(2)在选择性信任程度方面：5岁比4岁高, 而4岁和6岁之间、5岁和6岁之间则相同; 女孩在询问任务中比男孩表现出更高的选择性信任, 在赞同任务中则相同。那么, 幼儿的这种选择性信任是否受到信息正确性的调节?为此, 实验2采用2×3的被试间设计, 探讨信息提供者提供信息的正确性对4~6岁幼儿基于面孔吸引力的选择性信任的影响。结果显示：在正确性为50% vs. 50%条件下, 幼儿未对信息提供者产生选择性信任; 在正确性为25% vs. 75%条件下, 幼儿对提供较大正确性信息的低面孔吸引力者产生了选择性信任。研究结果表明：(1)在信息缺乏时, 4~6岁幼儿普遍存在有偏见的选择性信任; 女孩比男孩更易受到社会偏见因素的影响。(2)在信息明确时, 4~6岁幼儿也能做出相对理性的选择性信任。     

Facial attractiveness impressions precede trustworthiness inferences: lower detection thresholds and faster decision latencies

Prior research has found a relationship between perceived facial attractiveness and perceived personal trustworthiness. We examined the time course of attractiveness relative to trustworthiness evaluation of emotional and neutral faces. This served to explore whether attractiveness might be used as an easily accessible cue and a quick shortcut for judging trustworthiness. Detection thresholds and judgment latencies as a function of expressive intensity were measured. Significant correlations between attractiveness and trustworthiness consistently held for six emotional expressions at four intensities, and neutral faces. Importantly, perceived attractiveness preceded perceived trustworthiness, with lower detection thresholds and shorter decision latencies. This reveals a time course advantage for attractiveness, and suggests that earlier attractiveness impressions could bias trustworthiness inferences. A heuristic cognitive mechanism is hypothesised to ease processing demands by relying on simple and observable clues (attractiveness) as a substitute for more complex and not easily accessible information (trustworthiness).     

道德信息对面孔吸引力判断的无意识调节

抽象语言信息是否能够影响知觉?本研究在审美领域对此进行考察,探索无意识获取的道德信息是否影响个体对相应面孔吸引力的知觉判断。结果发现个体对面孔吸引力的知觉判断受到内隐道德信息的调节,且调节效应与面孔本身吸引力水平无关; 另外,面孔审美判断的反应时受到道德美丑和面孔吸引力的共同影响,尤其当两类信息相矛盾时被试需要更长的时间进行判断。研究结果表明抽象的社会道德信息可以对面孔吸引力的知觉判断产生自上而下的调节。     

Facial and full-length ratings of attractiveness related to the social interactions of young children

The present study investigated the relationship between ratings of attractiveness based on facial and those based on full-length photographs and how these ratings are related to peer interaction in preschoolers. Aggressive and prosocial peer interactions were observed in 38 preschool-age children. Attractive girls received more prosocial and fewer aggressive advances than unattractive girls. There was no differential treatment of boys related to attractiveness. Results were discussed in relationship to possible developmental implications and their parallel to the adult literature.     

Lip colour affects perceived sex typicality and attractiveness of human faces

The luminance contrast between facial features and facial skin is greater in women than in men, and women's use of make-up enhances this contrast. In black-and-white photographs, increased luminance contrast enhances femininity and attractiveness in women's faces, but reduces masculinity and attractiveness in men's faces. In Caucasians, much of the contrast between the lips and facial skin is in redness. Red lips have been considered attractive in women in geographically and temporally diverse cultures, possibly because they mimic vasodilation associated with sexual arousal. Here, we investigate the effects of lip luminance and colour contrast on the attractiveness and sex typicality (masculinity/femininity) of human faces. In a Caucasian sample, we allowed participants to manipulate the colour of the lips in colour-calibrated face photographs along CIELab L* (light--dark), a* (red--green), and b* (yellow--blue) axes to enhance apparent attractiveness and sex typicality. Participants increased redness contrast to enhance femininity and attractiveness of female faces, but reduced redness contrast to enhance masculinity of men's faces. Lip blueness was reduced more in female than male faces. Increased lightness contrast enhanced the attractiveness of both sexes, and had little effect on perceptions of sex typicality. The association between lip colour contrast and attractiveness in women's faces may be attributable to its association with oxygenated blood perfusion indicating oestrogen levels, sexual arousal, and cardiac and respiratory health.     

Attractiveness of Facial Profiles Is a Function of Distance From Archetype

The term archetype is used here to refer to a facial structure defined by certain geometric relationships that occur as a result of normal growth and that guarantee efficient mastication. Two experiments are reported that test whether or not facial attractiveness is related to this functional ideal. Attractiveness of female profiles was found to be related strongly to distance from archetype, and this relationship held at different age levels (but it was not mediated by apparent age level). In contrast, attractiveness was not related to the degree to which a given face conformed either to the golden section or to a cephalometric norm. Arguments are presented for defining attractiveness for a given individual rather than in terms of an absolute standard for all faces.     

面孔吸引力的回顾与前瞻

面孔吸引力是传递社会情感性信息的重要来源。面孔的平均化、对称性、性别二态性特征等因素会影响对面孔吸引力的评价。近年来, 研究者对面孔吸引力的研究已拓展到动态面孔上, 并采用fMRI技术发现当让被试评价有吸引力的面孔时, 杏仁核、眶额叶、腹侧枕叶等脑区被激活。研究者从进化论取向与认知取向两方面来解释人们为何偏好有吸引力的面孔。以往研究在研究内容、研究材料和研究对象等方面尚存不足, 这正是今后的研究方向。
