人脸特征信息反转效应的实验研究

结构信息和特征信息的研究是近年来人脸认知的热点,特征信息是否存在反转效应不同的理论对此有不同的看法。通过对平均人脸特征信息阈限的研究,发现:平均人脸特征信息的阈限具有明显的反转效应;特征信息的识别难度是决定特征信息的识别是否出现反转效应的重要因素。研究支持整体假设,认为成人是将人脸作为一个整体进行认知的。     

幼儿地图定向任务中几何线索的运用及发展

几何线索对儿童理解地图与现实空间之间的对应关系具重要意义。目前研究以几何地图为材料,通过定向任务,考察儿童对不同几何线索(拓扑关系、欧式几何特征、度量结构)的利用与发展,揭示了儿童对地图与现实空间之间对应关系的认知过程。研究发现,3岁儿童已初步发展出使用欧氏几何特征和度量结构表征空间位置的能力;但不同欧式几何特征(相对距离、角度、方向)被儿童掌握的时间存在明显差别;关于拓扑关系的研究较少,尚未掌握儿童利用该线索的发展规律。提高生态效度是未来研究需解决的主要问题。     

启动合成人脸的整体与局部加工:一项EEG研究

合成-人脸错觉指当加工合成人脸的上半部分时,下部分人脸由于人脸的整体加工优势而难以被忽略的现象。研究者采用合成-人脸错觉与Navon刺激发现,启动Navon刺激的整体或局部加工会影响人脸的整体加工,对理解人脸的加工机制起了重要作用。然而,该种影响的神经机制尚不明确。考虑到大脑左、右半球分别在加工局部与整体信息上存有优势,笔者预测Navon刺激启动是通过调节左、右半球的参与程度来影响对人脸的加工。本研究首次采用EEG技术,以枕区α节律为指标对该假设进行了检验。笔者重复以往行为研究结果,然而,无论对Navon刺激进行整体还是局部加工,α节律的能量总是右侧比左侧高,提示Navon刺激对人脸加工的影响并非通过改变大脑两半球的参与程度实现。     

人脸单维结构信息变化对人脸认知影响研究

本研究采用熟悉人脸和平均人脸照片作为实验材料对人脸结构信息单维变化对人脸认知影响进行了系统的研究。结果表明:(1)随着人脸结构信息的改变,被试对人脸正确辨认的变化趋势可分为不变区、快速增长区、高原区三个区域。(2)熟悉人脸结构信息单维变化的认知阈限值:眼睛移动为0.19°视角;鼻子移动为0.24°视角;嘴巴移动为0.20°视角。平均人脸分别为:眼睛移动为0.15°视角;鼻子移动为0.16°视角;嘴巴移动为0.16°视角。(3)在人脸单维结构信息变化的各维度上,平均人脸的认知阈限值要小于熟悉人脸的认知阈限值。     

身体转向模式对方位效应和相对位置效应的影响

在阅读故事而产生的想象场景中,观察者身体的物理转向（ｐｈｙｓｉｃａｌｒｏｔａｔｉｏｎ）模式或想象身体转向（ｉｍａｇｉｎｅｄｒｏｔａｔｉｏｎ）模式对物体搜索方位效应和相对位置效应产生影响。结果发现：方位效应独立于身体转向模式,说明对空间关系的理解是以想象自我（ｒｅｐｒｅｓｅｎｔｅｄｓｅｌｆ）为参照系的。相对位置效应独立于身体转向模式,说明物体间的拓扑结构导致了相对位置效应。     

公民责任意识:结构与动力分析及其教育的行动策略

针对当前公民责任意识教育存在的困难,文章从心理学角度出发,指出了当前研究所忽略的整体情境的动力和阻力问题,并尝试根据勒温的场论思想,对中国公民责任意识教育进行了整体和动力分析。通过整体结构的分析,提出了构成公民责任意识情境的三个维度:文化特征(差序格局-团体格局)、关系内容(传统社会的"义"、"利"、"情"和现代社会的"公")和现实程度(现实-虚构)维度。据此以拓扑心理学形式,举例说明了情境与人格交互作用中的动力和阻力因素。在上述个体层面分析的基础上,文章还简述了公民责任意识教育实践的团体动力学原理,并以展望未来论坛为例,介绍了正在兴起的公民责任意识教育的行动策略。

对素描教学的素描头像的几点认识

素描教学是造型艺术的基础,其技术训练要有相应的思想观念作指导。素描是要解决造型问题,但更重要的是解决观念认识问题。在素描教学中,素描头像的训练除了目的性之外,还必须掌握头像造型的规律和方法。要有正确的观察方法,从整体上来观察对象;还要培养立体的观念,用线条的明暗来表现素描头像。除此之外,还要了解头部形体结构比例和五官的造型特征。作者的感受和艺术素养也决定着艺术表现,所以在素描实践中,要讲究艺术规律和表现。     

阴阳五行思想与《黄帝内经》

阴阳五行思想是《黄帝内经》的哲学基础,但阴阳五行思想是如何与《黄帝内经》具体结合的呢?它体现的是一种什么样的思想呢?本文认为,《黄帝内经》运用阴阳五行思想,将人体自身以及人体与外部环境之间看作是一个有机的系统整体。阴阳说侧重于揭示有机整体的动因及其本质联系,五行说则侧重于揭示有机整体内部诸要素之间的结构关系和普遍联系。二者都代表了对整体要素之间关系的特定理解,从而共同强调了人体以及人体与环境之间的有机整体性。     

Featural processing in face preferences

Two experiments examined how practice and time pressure influence holistic processing, defined as the relative importance of feature interactions, in a face preference task. Participants rated 32 cartoon faces that varied along five dichotomous features (Experiment 1) or 27 realistic morphed faces that varied along three trichotomous dimensions (Experiment 2), under high and low time pressure (operationalized as a short vs. long stimulus presentation time), over a series of experimental blocks. In both experiments, the overall importance of facial features, but not of feature interactions, increased over blocks and, in one condition of Experiment 1, under high vs. low time pressure. Analyses of idiosyncratic importance indicated that the feature effects were due to the increasing importance of participants’ idiosyncratically most influential features. Functional differences between face preferences and face recognition are offered to explain and predict when facial features will be processed independently vs. holistically.     

Configural processing and perceptions of head tilt

Configural processing is important for face recognition, but its role in other types of face processing is unclear. In the present study, participants made judgments of head tilt for faces in which the vertical position of the internal facial region was varied. We found a highly reliable relationship between inner-face position and perceived head tilt. We also found that changes in inner-face position affected the perceived dimensions of an individual unchanged facial feature: compared to control faces, nearly two-thirds of faces in which the features had been moved down were judged to have a longer nose. This finding suggests an early integration of configural and featural processing to create a stable holistic percept of the face. The demonstration of holistic processing at a basic perceptual level (as opposed to during face recognition) is important as it constrains possible models of the relationships between featural and configural processing.     

Evidence of a shift from featural to configural face processing in infancy

Two experiments examined whether 4-, 6-, and 10-month-old infants process natural looking faces by feature, i.e. processing internal facial features independently of the facial context or holistically by processing the features in conjunction with the facial context. Infants were habituated to two faces and looking time was measured. After habituation they were tested with a habituation face, a switch-face, or a novel face. In the switch-faces, the eyes and mouth of the habituation faces were switched. The results showed that the 4-month-olds processed eyes and mouth by feature, whereas the 10-month-olds processed both features holistically. The 6-month-olds were in a transitional stage where they processed the mouth holistically but the eyes still as a feature. Thus, the results demonstrated a shift from featural to holistic processing in the age range of 4 to 10 months.     

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。     

Memory for faces: Encoding and retrieval operations

The reliable finding that trait judgments of faces yield better recognition memory than do feature judgments of faces is conceptualized as an encoding-specificity effect. Specifically, both trait-judgment encodings of faces and face-recognition tests are argued to be holistic, involving topographical information with between-feature processing. Consistent with the concept that encoding and retrieval operations interact to produce retrieval success, it was expected that a memory-for-face test using the Identi-kit (which requires reconstructions of the face at a feature level of analysis) would show trait-encoding tasks to be inferior to feature-encoding tasks. Eighty subjects were assigned randomly to judge a face on 10 trait dimensions (e.g., honesty-dishonesty) or on 10 feature dimensions (e.g., narrow nose-wide nose) and subsequently attempted to recognize the target among five distractors or to reconstruct the face from an Identi-kit. The significant interaction between encoding and retrieval operations indicated that the face was best identified under trait-encoding conditions but best reconstructed under feature-encoding conditions. The match between trait encoding and recognition in yielding high memory performance suggests strongly that trait judgments foster holistic processing of faces (i.e., interfeature topographical information is p-art of the context) and that the recognition of faces also is holistic. Finally, the utility of the feature- vs. holistic-processing distinction is questioned, and an alternative is proposed.     

Features and their configuration in face recognition

Tanaka and Farah (1993) have proposed a holistic approach to face recognition in which information about the features of a face and their configuration are combined together in the face representation. An implication of the holistic hypothesis is that alterations in facial configuration should interfere with retrieval of features. In four experiments, the effect of configuration on feature recognition was investigated by creating two configurations of a face, one with eyes close together and one with eyes far apart. After subjects studied faces presented in one of the two configurations (eyes-close or eyes-far), they were tested for their recognition of features shown in isolation, in a new face configuration, and in the old face configuration. It was found that subjects recognized features best when presented in the old configuration, next best in the new configuration, and poorest in isolation. Moreover, subjects were not sensitive to configural information in inverted faces (Experiment 2) or nonface stimuli (i.e., houses; Experiments 3 and 4). Importantly, for normal faces, altering the spatial location of the eyes not only impaired subjects’ recognition of the eye features but also impaired their recognition of the nose and mouth features—features whose spatial locations were not directly altered. These findings emphasize the interdependency of featural and configural information in a holistic face representation.     

眼睛区域构型信息与特征信息的跨维共变增益效应及其加工特异性

面孔知觉可能在区域尺度上发生多维信息整合, 但迄今无特异性实验证据。本研究在两个实验中操纵面孔眼睛区域或嘴巴区域的单维构型或特征信息, 测量人们觉察单维变化或跨维共变的敏感度, 以此检测面孔区域尺度上的多维信息整合有何现象与规律, 进而揭示面孔知觉的多维信息整合机制。实验获得3个发现：(1)正立面孔眼睛区域的信息变化觉察呈现出“跨维共变增益效应”, 跨维信息共变觉察的敏感度显著高于任意一种单维信息变化觉察的敏感度; (2)“跨维共变增益效应”只在正立面孔的眼睛区域出现, 在倒置面孔的眼睛区域、正立面孔的嘴巴区域或倒置面孔的嘴巴区域都没有出现, 因此具有面孔区域特异性和面孔朝向特异性; (3)就单维信息变化觉察而言, 眼睛区域的敏感度不会受到面孔倒置的损伤, 但是嘴巴区域的敏感度会受到面孔倒置的显著损伤。综合可知, 面孔知觉确实会发生区域尺度上的信息整合, 它不是普遍性的信息量效应, 而是特异性的眼睛效应(只发生在正立面孔的眼睛区域)。这是面孔整体加工(face holistic processing)在单维信息分辨和多维信息整合之间建立联系的必经环节。这提示我们对全脸多维信息知觉整合的理解需要从传统的面孔整体加工假设升级到以眼睛为中心的层级化多维信息整合算法(a hierarchical algorithm for multi-dimensional information integration)。     

Face recognition memory: The effects of exposure duration and encoding instruction

Two experiments test the effects of exposure duration and encoding instruction on the relative memory for five facial features. Participants viewed slides of Identi-kit faces and were later given a recognition test with same or changed versions of each face. Each changed test face involved a change in one facial feature: hair, eyes, chin, nose or mouth. In both experiments the upper-face features of hair and eyes were better recognized than the lower-face features of nose, mouth, and chin, as measured by false alarm rates. In Experiment 1, participants in the 20-second exposure duration condition remembered faces significantly better than participants in the 3-second exposure duration condition; however, memory for all five facial features improved at a similar rate with the increased duration. In Experiment 2, participants directed to use feature scanning encoding instructions remembered faces significantly better than participants following age judgement instructions; however, the size of the memory advantage for upper facial features was less with feature scanning instructions than with age judgement instructions. The results are discussed in terms of a quantitative difference in processing faces with longer exposure duration, versus a qualitative difference in processing faces with various encoding instructions. These results are related to conditions that affect the accuracy of eyewitness identification.     

Integration of internal and external facial features in 8- to 10-year-old children and adults

Investigation of whole-part and composite effects in 4- to 6-year-old children gave rise to claims that face perception is fully mature within the first decade of life (Crookes & McKone, 2009). However, only internal features were tested, and the role of external features was not addressed, although external features are highly relevant for holistic face perception (Sinha & Poggio, 1996; Axelrod & Yovel, 2010, 2011). In this study, 8- to 10-year-old children and adults performed a same–different matching task with faces and watches. In this task participants attended to either internal or external features. Holistic face perception was tested using a congruency paradigm, in which face and non-face stimuli either agreed or disagreed in both features (congruent contexts) or just in the attended ones (incongruent contexts). In both age groups, pronounced context congruency and inversion effects were found for faces, but not for watches. These findings indicate holistic feature integration for faces. While inversion effects were highly similar in both age groups, context congruency effects were stronger for children. Moreover, children's face matching performance was generally better when attending to external compared to internal features. Adults tended to perform better when attending to internal features. Our results indicate that both adults and 8- to 10-year-old children integrate external and internal facial features into holistic face representations. However, in children's face representations external features are much more relevant. These findings suggest that face perception is holistic but still not adult-like at the end of the first decade of life.     

When context hinders! Learn-test compatibility in face recognition

Some theories of holistic face processing propose that parts in faces (eyes, nose, mouth, etc.) are not explicitly represented. So far, the empirical evidence has shown that whole-to-part superiority is found when wholes are learned. We substantiated this using photographic faces. More importantly, we investigated whether learning parts also reveals holistic effects. This has not been attempted before. Four experiments showed that after learning facial parts, recognition of these parts was disrupted when the part was shown in the full face. This distraction effect was strongest when perceivers were not directed to focus on a particular facial feature. Thus, it is very difficult to ignore irrelevant parts in faces. In fact, this might be the essence of holistic face processing.
