The effects of the presence of a face and direct eye gaze on voice identity learning

We rarely become familiar with the voice of another person in isolation but usually also have access to visual identity information, thus learning to recognize their voice and face in parallel. There are conflicting findings as to whether learning to recognize voices in audiovisual vs audio-only settings is advantageous or detrimental to learning. One prominent finding shows that the presence of a face overshadows the voice, hindering voice identity learning by capturing listeners' attention (Face Overshadowing Effect; FOE). In the current study, we tested the proposal that the effect of audiovisual training on voice identity learning is driven by attentional processes. Participants learned to recognize voices through either audio-only training (Audio-Only) or through three versions of audiovisual training, where a face was presented alongside the voices. During audiovisual training, the faces were either looking at the camera (Direct Gaze), were looking to the side (Averted Gaze) or had closed eyes (No Gaze). We found a graded effect of gaze on voice identity learning: Voice identity recognition was most accurate after audio-only training and least accurate after audiovisual training including direct gaze, constituting a FOE. While effect sizes were overall small, the magnitude of FOE was halved for the Averted and No Gaze conditions. With direct gaze being associated with increased attention capture compared to averted or no gaze, the current findings suggest that incidental attention capture at least partially underpins the FOE. We discuss these findings in light of visual dominance effects and the relative informativeness of faces vs voices for identity perception.     

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。     

Configural and local processing of faces in children with Williams syndrome

Three experiments investigated face processing in children with Williams syndrome (WS). In Experiment 1, the ability to discriminate different aspects of faces was compared between WS subjects and a group of children individually matched for chronological age (CA-matches) and another group matched for mental age (MA-matches). In Experiments 2 and 3, the ability to process the local and configural aspects of geometrical patterns and faces was assessed within the same groups of subjects. The results indicated that the WSs' overall performance on face recognition was below that of the CA-matches, but similar to that of the MA-matches. This study revealed in addition that the CA- and MA-matches showed a bias toward a configural mode of face and geometrical shape processing, whereas children with WS did not show any bias. These findings suggest that face processing undergoes an abnormal developmental course in WS.     

Presidential Physiognomies: Altered Images, Altered Perceptions

Digitized facial images of Presidents Clinton, Reagan, and Kennedy were manipulated to test whether subtle feature alterations were powerful enough to shift social perceptions of them. It was expected that exaggeration of facial maturity cues would lead to shifts in perceptions of power (dominance, strength, and cunning) and warmth (honesty, attractiveness, and compassion). Each familiar face was made more neotenous by enlarging eyes and lips, and made more mature by reducing the sizes of these features. Undergraduate perceivers rated one version of each face. Though unaware of feature changes, perceivers were affected by them. In Study 1, neotenous features made Clinton seem more honest and attractive, even to perceivers who did not support him in the 1996 election. In Study 2, mature features made Kennedy, the youngest U.S. president, seem more cunning and made Reagan, the oldest president, appear less powerful and less warm; neotenous features reduced ratings of both Kennedy's and Reagan's power, whereas neotenizing the familiar face of Clinton increased ratings of his honesty and attractiveness without diminishing perceptions of his power. Overall, the results suggested that subtle alterations of proximate physiognomic cues can be used to manipulate perceivers' social perceptions of familiar political leaders.     

双关图作为面孔刺激与非面孔刺激对大脑事件相关电位的影响

用线条描绘的图形作为刺激材料,A为老鼠,C为老头,B为双关图(ambi-guous figure)。图形按两种顺序:A→B→C(Ⅰ)和C←B→A(Ⅱ)向被试呈现,每次呈现时间100ms。被试按刺激呈现方式分成两组,每组20人。被试接受图形的同时记录事件相关电位(ERPs),B图呈现后要求被试报告观察内容。对主观报告考验,发现双关图在Ⅰ呈现方式中作为非面孔刺激(老鼠)被认知,在Ⅱ呈现方式中作为面孔刺激(老头)被认知。ERPs分析表明,双关图作为面孔刺激被识别时,T_3、Pz的P_2波潜伏期比双关图作为非面孔刺激被识别时分别延长6.09ms和7.39ms,波幅没有显著差异;双关图作为面孔刺激时T_3、T_4、Pz和Oz的P_3波的潜伏期比双关图作为非面孔刺激时延长约15ms;波幅没有显著差异。     

THREE COMPARATIVE MAPS OF THE HUMAN

Abstract. This article is a response to the 1994 Star Island conference on the "Decade of the Brain" from a Jewish perspective. After a brief introduction about the logical function of models and maps, I compare and contrast three models of the human: Ezekiel's vision of the chariot in the Hebrew Scriptures, Franz Rosenzweig's geometry of the human face in Der Stern der Erlosung (the Star of Redemption), and a standard anatomical picture of the human brain. Whereas Rosenzweigs face is seen to be compatible with Ezekiel's chariot, both are seen to be radically distinct from the implicit conception of what a human being is in modern medical science. I conclude with a suggestion that the differences are to be understood in terms of their different intended functions and express my hope for some new kind of model that will incorporate the functional advantages of both.     

Familiarity Bias and Belief Reversal in Relative Likelihood Judgment

People are often called on to make an assessment of the relative likelihood of events (e.g., which of two investments is more likely to outperform the market?) and their complements (which of the two investments is more likely to perform no better than the market?). Probability theory assumes that belief orderings over events and their complements should mirror each other (i.e., P(A) >/= P(B) iff P (not-A) 相似文献   

面孔社会知觉中的表情效应

面孔社会知觉指知觉者基于面孔所有者的面孔信息对面孔所有者的人格特质等进行知觉推断的过程。表情是人们进行面孔社会知觉的关键线索之一。表情可以单独通过本身的局部特征和结构信息影响面孔社会知觉, 还可以通过对知觉者的情绪诱发或表情传达的行为倾向性来影响面孔社会知觉的结果。考虑到现实生活中多种表情类型的组合及特定表情(伪装表情)高频出现以及知觉者判断人格特质存在主观性, 未来研究要加强多种表情类型对面孔社会知觉的影响研究, 还要进一步将知觉者因素作为未来研究的变量。     

上下文熟悉效应对元记忆监测和记忆的影响

在认知任务中,伴随编码和检索的外围信息被称为上下文,其本身并不是编码或检索的目标。如果学习时的上下文在其后进行提取时重复出现,不管是否对应之前的学习项目,都会增加个体再认正确的概率。这种由于上下文增强项目熟悉感而促进记忆效果的现象就称为上下文熟悉效应。本研究通过两个实验探究上下文熟悉效应对元记忆监测及记忆的影响机制。其中,元记忆监测是以学习判断和信心判断为指标。记忆成绩则是以再认正确率为指标。研究结果显示:第一,上下文熟悉效应影响元记忆监测:学习判断等级上,恢复条件显著高于新条件,且不受任务难度影响; 信心判断等级上,简单任务时恢复条件与新条件无显著差异,困难任务时恢复条件显著高于新条件。第二,上下文熟悉效应影响记忆成绩:再认成绩上,简单任务时新条件显著高于恢复条件; 困难任务时恢复条件显著高于新条件。研究得出结论:上下文熟悉效应对元记忆监测和记忆都有显著影响,任务难度起调节作用。     

Individual differences in face and voice matching abilities: The relationship between accuracy and consistency

Deciding whether two different face photographs or voice samples are from the same person represent fundamental challenges within applied settings. To date, most research has focussed on average performance in these tests, failing to consider individual differences and within‐person consistency in responses. Here, participants completed the same face (Experiment 1) or voice matching test (Experiment 2) on two separate occasions, allowing comparison of overall accuracy across the two timepoints as well as consistency in trial‐level responses. In both experiments, participants were highly consistent in their performances. In addition, we demonstrated a large association between consistency and accuracy, with the most accurate participants also tending to be the most consistent. This is an important result for applied settings in which organisational groups of super‐matchers are deployed in real‐world contexts. Being able to reliably identify these high performers based upon only a single test informs regarding recruitment for law enforcement agencies worldwide.
