人名发音与面孔的形状概念关联：来自行为和ERP的证据

已有行为研究揭示知觉者倾向于认为圆唇音名与圆脸、扁唇音名与尖脸身份一致的效应。为进一步探明该效应在人脑内的加工进程及发生机制,本研究在人名发音启动面孔（脸型判断任务）范式下进行了脑电实验。结果发现,被试在一致条件下的正确率显著高于不一致条件,一致条件下的反应时显著低于不一致条件;不一致条件在大脑中央-顶区诱发出更负的N400成分。结果说明,人名发音与面孔存在形状概念的关联,该结果支持了人名发音与脸型的跨模态对应是共享内涵属性所致的观点。     

道德概念垂直空间隐喻的心理现实性及双向映射

研究以大学生为被试,通过三个实验考察道德概念垂直空间隐喻的心理现实性及双向映射。实验1采用面孔图片和道德词汇的匹配记忆任务发现,道德词出现在上方时,被试对词语和面孔的匹配再认率更高;不道德词出现在下方时,被试对词语和面孔的匹配再认正确率更高。结果证实了道德概念的垂直空间隐喻的心理现实性。实验2通过道德评价任务发现,被试倾向于把空间上方出现的面孔评价为更加道德,把在空间下方的面孔评价为更加不道德,证实了空间信息对道德评价的影响。实验3采用带有空间位置信息的词语记忆任务。结果表明,在位置判断任务中,被试更多地将道德词判断为在上方出现过,更多地将不道德词判断为在下方出现过。结果显示词语的道德色彩影响了空间信息判断。研究结论:传统道德概念垂直空间隐喻存在心理现实性;道德概念和空间概念之间存在双向映射。     

面孔相似性判断中各部件的权重分配

采用多级估量法,通过分析不同隶属度的部件样例组合成的面孔样例对原型的隶属度,考察耳朵、脸型、眼睛和嘴巴等部件在面孔相似性判断中的作用。结果发现,面孔相似性判断中,人们对不同面孔部件赋予的权重并不相同,对脸型和嘴巴赋予的权重较大,而对耳朵和眼睛赋予的权重较小。表明,面孔各部件在面孔相似性判断中的作用不同,相对于耳朵和眼睛,脸型和嘴巴的作用更大;面孔内部特征和外部特征的划分方法并不一定适合于面孔相似性判断。     

象似性和手语学习经验对中国手语-汉语跨模态语义启动效应的影响

采用启动条件下的词汇判断任务,考察熟练手语使用者和无手语经验成年听人的跨模态语义启动效应。结果发现：1)在象似词条件下,两组被试判断汉语语义相关词的反应时均快于语义无关词,说明手语象似词和汉语词之间存在跨模态语义启动效应。2)在非象似词条件下,仅手语熟练被试判断汉语语义相关词的反应时快于语义无关词,无手语经验被试判断汉语语义相关词和无关词的速度没有差异。这是由于前者心理词库中的手语词和口语词共享语义表征,而后者主要依赖手语象似词的视觉模拟性。整个研究表明,中国手语和汉语间存在跨模态语义启动效应,但该效应受到手语词象似性和手语学习经历的调节。     

本族和异族面孔的视觉工作记忆容量:面孔特征的影响

采用延迟探测刺激匹配再认任务,考察面孔种族和内外部特征是否会影响面孔视觉工作记忆容量。被试先识记2或4张中国人或白人的真实面孔图片,一半有内部特征(眼睛、鼻子和嘴巴),另一半有内部和外部特征(脸型、发型),再进行面孔再认判断。采用Cowan’s K值的分析显示,我国被试对本族和异族面孔的视觉工作记忆容量没有差异,但面孔数量与特征多少会影响面孔工作记忆容量,表明对本族和异族面孔的视觉加工不同。     

自闭症谱系障碍儿童对面孔加工的同龄偏向效应

采用视觉追踪技术,探讨自闭症谱系障碍(autism spectrum disorders, ASD)儿童面孔加工的同龄偏向效应。实验1选取19名ASD儿童和23名生理年龄匹配的普通儿童(typically developing, TD)为被试,通过自由观看同龄和异龄中性面孔,探讨ASD儿童是否存在面孔加工的同龄偏向效应;实验2选取22名ASD儿童和生理年龄匹配的25名TD儿童,通过自由观看快乐、愤怒和恐惧面孔,探讨情绪对ASD儿童面孔加工同龄偏向的影响。结果发现,(1)ASD儿童对同龄中性面孔的注视时间显著大于异龄中性面孔;(2)ASD儿童在愤怒和恐惧情绪下对同龄面孔的注视时间显著大于异龄面孔,而在快乐情绪下同龄和异龄的注视时间则无显著差异。这表明ASD儿童对面孔的注视加工存在同龄偏向效应,且受情绪的影响。     

第一印象中面孔-人格知觉和语音-人格知觉的异同

人们会根据陌生人的面孔线索或语音线索迅速地对其人格特质进行主观推断而形成第一印象。面孔-人格知觉第一印象和语音-人格知觉第一印象在维度结构和内在机制上具有相似性; 在对具体人格特质和维度的敏感性, 以及具体的认知机制方面又具有各自的特异性。未来研究可以基于同一批被知觉者开展面孔-人格知觉第一印象和语音-人格知觉第一印象的直接比较, 并着力探究二者的过程特点, 以及人格知觉第一印象形成时面孔和语音知觉的跨模态整合效应。     

刻板印象激活效应对社会分类的影响

采用改进的flanker范式,探讨了刻板印象激活效应对社会分类的影响,并考察了匹配刺激出现概率对刻板印象激活效应影响社会分类的调节作用。实验一发现,性别刻板印象激活后,按性别分类时,匹配刺激中和不匹配刺激中面孔分类反应时之间的差异是显著的,但按年龄分类时,二者间的差异不显著。实验二表明,匹配刺激出现概率为80%时和50%时,匹配刺激中和不匹配刺激中面孔分类反应时之间的差异是显著的;但当匹配刺激出现概率为20%时,二者间的差异不显著。结果表明,刻板印象激活效应对与该刻板印象对应的社会分类有显著的影响,对与该刻板印象无关社会分类不会产生影响。刻板印象激活效应对社会分类的影响受匹配刺激出现概率的调节。     

发音动作和声音在产生效应中的作用：基于fNIRS的研究

产生效应指朗读的记忆成绩好于默读的,然而目前还不清楚发音动作和声音在其中的作用。本研究采用fNIRS技术,考察大学生朗读、唇读、默读三种阅读方式时的记忆成绩和大脑激活模式。结果发现：（1）朗读和唇读的记忆成绩显著高于默读的;（2）朗读和唇读时在初级运动皮层、布洛卡区和威尔尼克区的激活程度均显著大于默读时的;（3）朗读时在威尔尼克区的激活程度显著大于唇读时的。这表明,发音动作相对声音在产生效应中的作用更大。     

再探框架对风险决策行为的影响

期望理论运用Ｓ状的价值函数和非线性的权重函数来解释和预测框架效应。“齐当别”抉择模型将不同框架下的抉择行为简单地看成是“最好可能结果之间的取舍”或者“最坏可能结果之间的取舍”。本研究设计了一“匹配”技术,并用此对作者所报告过的支持框架效应与不支持框架效应的选择问题加以再检验。实验表明,采用不同的框架并不能预测性地决定不同的抉择偏爱,而匹配结果所示的“齐当别”策略则能更好地对所收集到的有关框架效应的数据作出解释。     

The effects of distinctiveness on memory and metamemory for face–name associations

We examined the influence of face and name distinctiveness on memory and metamemory for face–name associations. Four types of monitoring judgements were solicited during encoding and retrieval of face–name pairs that contained distinct or typical faces (Experiment 1) or names (Experiment 2). The beneficial effects of distinctiveness on associative memory were symmetrical between faces and names, such that relative to their typical counterparts, distinct faces enhanced memory for names, and distinct names enhanced memory for faces. These effects were also apparent in metamemory. Estimates of prospective and retrospective memory performance were greater for face–name associations that contained a distinct face or name compared with a typical face or name, regardless of whether the distinct item was a cue or target. Moreover, the predictive validity of prospective monitoring improved with name distinctiveness, whereas the predictive validity of retrospective monitoring improved with facial distinctiveness. Our results indicate that distinctiveness affects not only the strength of the association between a face and a name, but also the ability to monitor that association.     

Integration of faces and voices, but not faces and names, in person recognition

Recent studies on cross-modal recognition suggest that face and voice information are linked for the purpose of person identification. We tested whether congruent associations between familiarized faces and voices facilitated subsequent person recognition relative to incongruent associations. Furthermore, we investigated whether congruent face and name associations would similarly benefit person identification relative to incongruent face and name associations. Participants were familiarized with a set of talking video-images of actors, their names, and their voices. They were then tested on their recognition of either the face, voice, or name of each actor from bimodal stimuli which were either congruent or novel (incongruent) associations between the familiarized face and voice or face and name. We found that response times to familiarity decisions based on congruent face and voice stimuli were facilitated relative to incongruent associations. In contrast, we failed to find a benefit for congruent face and name pairs. Our findings suggest that faces and voices, but not faces and names, are integrated in memory for the purpose of person recognition. These findings have important implications for current models of face perception and support growing evidence for multisensory effects in face perception areas of the brain for the purpose of person recognition.     

The effects of distinctiveness on memory and metamemory for face-name associations

We examined the influence of face and name distinctiveness on memory and metamemory for face-name associations. Four types of monitoring judgements were solicited during encoding and retrieval of face-name pairs that contained distinct or typical faces (Experiment 1) or names (Experiment 2). The beneficial effects of distinctiveness on associative memory were symmetrical between faces and names, such that relative to their typical counterparts, distinct faces enhanced memory for names, and distinct names enhanced memory for faces. These effects were also apparent in metamemory. Estimates of prospective and retrospective memory performance were greater for face-name associations that contained a distinct face or name compared with a typical face or name, regardless of whether the distinct item was a cue or target. Moreover, the predictive validity of prospective monitoring improved with name distinctiveness, whereas the predictive validity of retrospective monitoring improved with facial distinctiveness. Our results indicate that distinctiveness affects not only the strength of the association between a face and a name, but also the ability to monitor that association.     

Interference resolution in face perception and name retrieval

Selective retrieval is a rather difficult task, and especially so when one attempts to retrieve personal representations such as faces or names. Retrieval of memories under strong competition conditions is pervasive in human memory and some have suggested that inhibitory control is used to overcome interference between competing stimuli. In the present study, we used the retrieval practice paradigm to investigate if competition among personal representations (such as facial features and names) is also resolved by inhibitory mechanisms. This question is theoretically relevant, since personal representations have been said to have a special status on cognition. Moreover, some models of face recognition assume that interference can arise between different representations, but that this interference would be automatically and rapidly solved, with no need for a controlled inhibitory mechanism to act. In two experiments we showed RIF for facial features and familiar names, but only when participants had to actively retrieve some information. This suggests that personal information is subject to mechanisms of inhibitory control, which could help explain everyday life difficulties in processes such as face feature recognition or name retrieval.     

A social Bouba/Kiki effect: A bias for people whose names match their faces

The “bouba/kiki effect” is the robust tendency to associate rounded objects (vs. angular objects) with names that require rounding of the mouth to pronounce, and may reflect synesthesia-like mapping across perceptual modalities. Here we show for the first time a “social” bouba/kiki effect, such that experimental participants associate round names (“Bob,” “Lou”) with round-faced (vs. angular-faced) individuals. Moreover, consistent with a bias for expectancy-consistent information, we find that participants like targets with “matching” names, both when name-face fit is measured and when it is experimentally manipulated. Finally, we show that such bias could have important practical consequences: An analysis of voting data reveals that Senatorial candidates earn 10% more votes when their names fit their faces very well, versus very poorly. These and similar cross-modal congruencies suggest that social judgment involves not only amodal application of stored information (e.g., stereotypes) to new stimuli, but also integration of perceptual and bodily input.     

I Recognize Your Face, But I Can't Remember Your Name: A Grown up Explanation

Contemporary models of face recognition explain everyday difficulties in name retrieval by proposing that name information can only be accessed after semantic information (e.g. Bruce & Young, 1986) or by proposing an architecture which puts name retrieval at a disadvantage (e.g. Burton& Bruce,1992). Experiments reportedhere examined the time requiredto access name and semantic details by adult and child subjects. In Experiment 1 adult subjects took more time to match familiar faces to names than to other semantic details (e.g. occupation), a finding consistent with all the previous literature on name retrieval. Experiment 2, however, showed that the youngest subjects were significantly faster in matching familiar faces to names than to semantic details. Experiment 3 also showed that children were faster at accessing names than occupations when giving vocal responses to presentations of familiar faces. These findings are not predicted by rigidly sequential models of face recognition and are discussed with specific reference to the ontogenesis of models based on a more flexible connectionist architecture.     

Face processing and name retrieval in an anomic aphasic: names are stored separately from semantic information about familiar people

Recent models of face recognition have proposed that the names of familiar people are accessed from a lexical memory store that is distinct from the semantic memory store that holds information about such things as a familiar person's occupation and personality. Names are nevertheless retrieved via the semantic system. If such models are correct, then it should be possible for a patient to have full access to semantic information about familiar people while being unable to name many of them. We report this pattern in an anomic aphasic patient, EST, whose inability to recall the names of familiar people occurred in the context of a general word-finding problem. EST showed a preserved ability to access semantic information from familiar faces, voices, and spoken and written names and to process facial expressions, but he was unable to name many familiar faces. These findings are compatible with current models of face processing and challenge models which propose that names are stored alongside semantic information in a general-purpose long-term memory store.     

Who do you look like? Evidence of facial stereotypes for male names

The present research provides evidence that people use facial prototypes when they encounter different names. In Experiment 1, participants created face exemplars for fifteen common male names, subsets of which were endorsed as good examples by a second set of participants. These most typical faces were morphed to create face-name prototypes. In Experiment 2, participants matched one of the names to each of the prototype faces from Experiment 1. Participants’ matching choices showed convergence in naming the prototypes for many of the names. Experiment 3 utilized these same prototypes in a learning task designed to investigate if the face-name associations revealed in Experiment 2 impacted the learnability of the names. Participants learned face-name pairings that had a higher association (based on frequencies from Experiment 2) faster than pairings with a low association. Results suggest a more direct relationship between faces and names than has been previously proposed.     

Recognition without face identification

Recognition without identification is the finding that participants can recognize recognition test items as having been previously studied when the test items themselves are presented in such a way that their identification is hindered. The present study demonstrates this phenomenon in face recognition. Participants studied names of celebrities before receiving a recognition test containing pictures of celebrity faces. Half of the pictures were of celebrities whose names were studied; half were of celebrities whose names were not studied. Participants attempted to identify each face on the test and also rated the likelihood that each person's name was studied. Among the faces that went unidentified, ratings discriminated between celebrities whose names were studied and celebrities whose names were not studied. This recognition without face identification effect is dependent upon the sense of being in a tip-of-the-tongue state for a particular name. Theoretical implications of the results are discussed.     

Gender is a dimension of face recognition

In an experiment, the authors investigated the impact of gender categorization on face recognition. Participants were familiarized with composite androgynous faces labeled with either a woman's first name (Mary) or a man's first name (John). The results indicated that participants more quickly eliminated faces of the opposite gender than faces of the same gender than the face they were looking for. This gender effect did not result from greater similarity between faces of the same gender. Rather, early gender categorization of a face during face recognition appears to speed up the comparison process between the perceptual input and the facial representation. Implications for face recognition models are discussed.
