面孔识别异族效应的研究

异族效应是面孔识别过程中一种非常稳定的现象,表现为对本族面孔的识别与再认成绩显著高于异族面孔.脑成像研究也证实了这两类面孔在神经表征上的差异.关于该效应主要有知觉经验说与社会分类说两种理论解释,但围绕着其心理机制仍然存在着很多争议然,未来的研究需要考虑族群认同等社会-人格因素对于异族效应的影响,并注意考察本族面孔与异族面孔有提取阶段可能存在的神经活动的差异.     

Newborns' face recognition over changes in viewpoint

The study investigated the origins of the ability to recognize faces despite rotations in depth. Four experiments are reported that tested, using the habituation technique, whether 1-to-3-day-old infants are able to recognize the invariant aspects of a face over changes in viewpoint. Newborns failed to recognize facial perceptual invariances between profile and full-face poses (Experiment 1), and profile and 3/4 poses (Experiment 3). Conversely, newborns recognized the identity of a face through full-face and 3/4 poses (Experiment 2). This result cannot be explained as a consequence of newborns' inability to discriminate between the full-face and 3/4 points of view (Experiment 4). Overall, evidence was provided that newborns are able to derive a representation of an unfamiliar face that is resilient to a certain degree of rotation in depth, from full-face to 3/4 and vice versa.     

面孔倒置效应的研究与理论述评

面孔倒置效应是指, 个体对倒置面孔的再认成绩显著低于对正立面孔的再认成绩, 而且, 与普通物体的倒置效应相比, 面孔的倒置效应更大。研究者们针对面孔倒置效应提出了多种理论假说, 两种主要的理论解释是：第一, 倒置面孔破坏了面孔的结构特征, 影响了面孔的整体加工, 所以, 个体对倒置面孔的再认成绩较差; 第二, 眼睛在面孔加工中起重要作用, 尤其在倒置面孔中的作用更明显, 使得倒置面孔N170波幅较高。ERP和fMRI研究提示, 未来研究需要进一步明确眼睛、注意等在面孔倒置效应中的作用。     

面孔识别中的构形加工与特征加工

面孔信息的分类方法一直复杂多样, 相关研究数据丰富, 但所用概念混杂。构形加工与特征加工作为使用最频繁的分类方法, 其可靠性越来越受研究者们关注。从近40年来的相关文献中选择引用率高的文献做参考, 遵循不同研究方法相互印证的原则分析数据, 提出构形加工与特征加工的区分是面孔识别中重要并且可靠的加工类型划分, 但确认两者在知觉加工上的先后关系以及在个体发展上的先后顺序尚缺乏稳定一致性的实验依据。     

Infants' Differential Processing of Female and Male Faces

ABSTRACT— Infants show an interesting asymmetry in face processing: They are more fluent in processing female faces than they are at processing male faces. We hypothesize that such processing asymmetry results from greater experience with female faces than with male faces early in development. Asymmetrical face processing may have long-lasting implications for development of face recognition, development of knowledge structures regarding females and males, and social-information processing. We encourage researchers to use both female and male faces in their face-perception research and to conduct separate analyses for female and male faces.     

Perception and Emotion: How We Recognize Facial Expressions

ABSTRACT— Perception and emotion interact, as is borne out by studies of how people recognize emotion from facial expressions. Psychological and neurological research has elucidated the processes, and the brain structures, that participate in facial emotion recognition. Studies have shown that emotional reactions to viewing faces can be very rapid and that these reactions may, in turn, be used to judge the emotion shown in the face. Recent experiments have argued that people actively explore facial expressions in order to recognize the emotion, a mechanism that emphasizes the instrumental nature of social cognition.     

The social function of imitation in severe dementia

We report the case of Jessie, an individual with severe Alzheimer's disease. Over two sessions, we examine Jessie's spontaneous conversation behaviour and urge to communicate using the ‘still face’ paradigm. Spontaneous and deliberate imitation are also examined to identify their importance in social interactions in severe dementia. Although Jessie has difficulty producing meaningful conversation, she retains the urge to communicate and participate in social interactions. These results confirm the importance of imitation in facilitating and maintaining people with communication problems in the social world. Copyright © 2006 John Wiley & Sons, Ltd.     

Masks and Faces in the Setting at the Time of Coronavirus

The “health emergency” forced analysts to seek new ways of continuing with analysis. The article focuses, in particular, on the changes brought about in the setting by the presence of the sanitary mask, following a line that begins with the theme of the “mask” in the collective uses of human cultures, and develops through the Jungian concept of persona, as opposed to the “face” that may convey an authentic image of oneself. A clinical vignette illustrates the issues that the mask raises in the setting by obstructing the communication of emotions. When there is no transformative processing of concrete data, “unmasking” can also lead to an uncanny encounter and to moments of darkness and confusion in analysis, when the analyst experiences the kind of “unconscious identity” between therapist and patient that Jung defined as nigredo. The article is intended as a contribution to the analytic community's current reflections on the new and unforeseen challenges encountered in analysis at the time of the Coronavirus. It is possible to learn from these experiences with a view to integrating new elements and thus modify one's own internal setting, the compass with which each analyst orientates himself.     

Metacognition during unfamiliar face matching

Kruger and Dunning (1999) described a metacognitive bias in which insight into performance is linked to competence: poorer performers are less aware of their mistakes than better performers. Competence-based insight has been argued to apply generally across task domains, including a recent report investigating social cognition using a variety of face-matching tasks. Problematically, serious statistical and methodological criticisms have been directed against the traditional method of analysis used by researchers in this field. Here, we further illustrate these issues and investigate new sources of insight within unfamiliar face matching. Over two experiments (total N = 1077), where Experiment 2 was a preregistered replication of the key findings from Experiment 1, we found that insight into performance was multi-faceted. Participants demonstrated insight which was not based on competence, in the form of accurate updating of estimated performance. We also found evidence of insight which was based on competence: the difference in confidence on correct versus incorrect trials increased with competence. By providing ways that we can move beyond problematic, traditional approaches, we have begun to reveal a more realistic story regarding the nature of insight into face perception.     

The sibling familiarity effect: Is within-person facial variability shared across siblings?

Humans are experts at familiar face recognition, but poor at unfamiliar face recognition. Familiarity is created when a face is encountered across varied conditions, but the way in which a person’s appearance varies is identity-specific, so familiarity with one identity does not benefit recognition of other individuals. However, the faces of biological siblings share structural similarities, so we explored whether the benefits of familiarity are shared across siblings. Results show that familiarity with one half of a sibling pair improves kin detection (experiment 1), and that unfamiliar face matching is more accurate when targets are the siblings of familiar versus unfamiliar individuals (experiment 2). PCA applied to facial images of celebrities and their siblings demonstrates that faces are generally better reconstructed in the principal components of a same-sex sibling than those of an unrelated individual. When we encounter the unfamiliar sibling of someone we already know, our pre-existing representation of their familiar relation may usefully inform processing of the unfamiliar face. This can benefit both kin detection and identity processing, but the benefits are constrained by the degree to which facial variability is shared.
