Affective theory of mind inferences contextually influence the recognition of emotional facial expressions

The recognition of emotional facial expressions is often subject to contextual influence, particularly when the face and the context convey similar emotions. We investigated whether spontaneous, incidental affective theory of mind inferences made while reading vignettes describing social situations would produce context effects on the identification of same-valenced emotions (Experiment 1) as well as differently-valenced emotions (Experiment 2) conveyed by subsequently presented faces. Crucially, we found an effect of context on reaction times in both experiments while, in line with previous work, we found evidence for a context effect on accuracy only in Experiment 1. This demonstrates that affective theory of mind inferences made at the pragmatic level of a text can automatically, contextually influence the perceptual processing of emotional facial expressions in a separate task even when those emotions are of a distinctive valence. Thus, our novel findings suggest that language acts as a contextual influence to the recognition of emotional facial expressions for both same and different valences.     

高善良特质在情绪调节行动控制中的内隐优势

基于善良特质在中国人人格修养中的重要价值, 本研究以情绪调节的行动控制理论为模型参照, 设计了三项行为实验检验善良特质的导向性与内隐情绪调节的关系。研究1采用Stroop任务, 比较高低善良被试判断人际关系词颜色时是否受到色词内容的干扰, 结果发现, 高(vs.低)善良被试对人际关系积极词更敏感; 研究2采用情绪调节内隐联想测验任务比较高低善良被试的情绪调节内隐态度差异, 结果发现高(vs.低)善良被试更倾向于采用控制型情绪调节方式调节情绪; 研究3在诱发被试负性情绪条件下, 采用面孔表情视觉搜索任务间接考察高低善良被试在内隐情绪修复效果上的差异, 结果显示高(vs.低)善良被试搜索愤怒背景下高兴面孔的速度更快。三项实验结果一致地表明, 高善良特质利他重感情的行动目的性在情绪调节的行动控制中具有内隐优势, 对积极的心理健康起促进作用。     

Development and validation of the Eyewitness Metamemory Scale

Metamemory can be defined as the knowledge about one's memory capabilities and about strategies that can aid memory. In this paper, we describe the development and validation of the Eyewitness Metamemory Scale (EMS), tailored specifically for use in face memory and eyewitness identification settings. Participants (N = 800) completed the EMS and other measures on general metamemory. Results from exploratory and confirmatory factor analysis revealed good factorial validity, internal consistency, and content validity. The EMS items emerged into three distinct factors: memory contentment, memory discontentment, and memory strategies. The EMS is a brief and easily administrable questionnaire that might be used to assess self‐ratings of face recognition capacity and use of strategies to encode faces.     

知觉场理论对面孔知觉年龄偏差效应的解释

使用融合面孔范式和倒置面孔范式来研究面孔知觉的年龄偏差效应,检验知觉场能否作为面孔整体加工的指标,并以此发展年龄偏差的整体加工解释。结果发现：（1）成人和儿童在加工正立面孔时的知觉场均大于加工倒置面孔时的知觉场;（2）在加工正立面孔时,成人加工本年龄面孔比加工他年龄面孔的知觉场更大。上述结果表明：（1）知觉场大小可以作为面孔整体加工的指标,且受面孔朝向的影响;（2）知觉场假设可以解释面孔的年龄偏差效应。     

以貌取人可行吗？——基于面孔的特质推理及准确性

面孔—特质推理（face - traits inference）是知觉者凭借面孔推断他人特质的心理过程。面孔特征、构型以及表情是特质推理的主要线索。其心理机制可从生理、进化和认知取向等方面进行解释。以往研究发现,面孔-特质推理具有适度准确性。其准确性主要受到知觉对象的面孔吸引力,知觉者的身心特征、知识经验和文化背景的影响;情境也是影响准确性的重要因素。未来研究需在面部线索、准确性指标、准确性的影响因素以及理论框架等方面进行探讨。     

婴儿图式及其加工的性别差异

婴儿图式 (baby schema, or Kindchenschema) 是指人们对一系列婴儿特征的一种心理表征, 这些特征包括婴儿所特有的高额头、大眼睛和圆脸蛋等知觉特征。婴儿图式可以诱发人们的积极情绪, 并引起关爱、照顾婴儿的行为, 从而满足个体生存以及繁衍的需要。对婴儿面孔的加工存在性别差异, 女性对婴儿特征比男性更敏感, 原因可能有四种：大脑结构的不同、女性独有的情绪反应、女性生殖激素的影响和早期环境的影响。未来的研究可以进一步揭示婴儿图式的特异性神经机制, 并从性别差异入手, 进一步探讨母爱与婴儿图式的相互作用。     

人类面孔识别工作记忆的脑电位特征

采用事件相关电位(ERPs)技术探索延迟匹配任务范式下面孔识别工作记忆的脑电位特征。实验以面孔图片为刺激,在校大学生被试完成靶匹配工作记忆任务。结果发现,被试识别靶面孔及分心物面孔时均在枕颞区两侧诱发N170,且靶与分心物的N170振幅在相同电极上都没有显著差异,在颞区两侧的P7和P8上差异显著;无论靶面孔还是分心物面孔,工作记忆的 ERPs均产生了 P300成分。在分别追踪新靶和熟悉靶的工作记忆任务条件下,靶与分心物的ERPs波形在250 ms后出现分离,且靶刺激波幅均比分心物更正,新靶比熟悉靶更正。熟悉分心物与新分心物之间显示出250~650 ms的前额区旧/新效应,在晚期的450~650 ms时段,新工作记忆比旧工作记忆波幅更正。这些结果表明,面孔识别的N170效应可能反映的是面孔知觉的整体加工,且 N170的右半球优势具体为颞区的右侧优势;先前的面孔学习会影响工作记忆期间大脑对面孔的识别反应。     

孤独症谱系障碍患者对种族情境中本异族面孔的眼动模式

本研究采用眼动技术探讨孤独症谱系障碍(ASD)患者对背景中的本异族面孔的加工特点。研究采用2（组别）×2（面孔种族）×3（背景）的混合设计,让16名16-25岁的ASD患者和17名生理年龄匹配的正常人完成变化检测任务,并记录他们的眼动。结果显示：与正常人相比,ASD患者的面孔辨别力更低;他们的眼动呈现更多的面孔-背景眼跳和更多的上下半脸眼跳;两组被试的上下半脸眼跳的次数受到面孔种族以及面孔和背景是否一致的影响。结论：在行为指标上,正常人出现了本族效应,而ASD患者没有出现本族效应;在眼动上,ASD患者呈现与正常人相似的面孔注视时间,但比正常人呈现更多的眼跳。面孔的背景影响了面孔辨别力以及上下半脸眼跳轨迹。     

自我面孔加工与注意——来自反眼跳的证据

作为一种具有重要生物学意义和社会性的视觉刺激,面孔比一般的视觉刺激更容易吸引注意.本研究以Eyelink 2000车载眼动仪为工具,在混合呈现的反眼跳任务中考察了32名大学生被试对自我面孔、恋人面孔和陌生面孔加工中的注意捕获和维持注意方面的特点.结果发现:在朝向眼跳任务中,自我面孔和恋人面孔的眼跳错误率显著低于异性陌生面孔,并且自我面孔和恋人面孔都表现出了保持注意的优势;而在反眼跳任务中,自我面孔、恋人面孔与陌生人面孔的反眼跳错误率和眼跳潜伏期没有显著差异.这一结果表明:自我面孔、恋人面孔与陌生面孔之间在高水平视觉特征上的差异没有达到影响反眼跳的最小可觉察差别量.因此,在反眼跳任务中面孔的优势效应掩盖了自我相关信息加工的优势,导致了自我面孔与陌生面孔没有表现出对注意捕获或保持注意上的差异.     

Face category differentially influences face memories after a delay

ABSTRACT

Faces belonging to the same category as the perceiver are better recognised than faces from different categories when tested immediately. After a delay, the same-category benefit persists and response bias becomes more liberal for other-category but not same-category faces. These effects are typically attributed to better encoding of same-category than other-category faces. To determine whether bias effects after a delay persist when immediate accuracy differences are minimised, Hispanic and Caucasian participants were given more study time for other-category than same-category faces. Memory was tested immediately and after a two-day delay. Discrimination accuracy was higher for other-category than for same-category faces during both test sessions. Bias was equivalent immediately, but after the delay, bias was more conservative for same-category than for other-category faces, especially in Caucasian participants. These results suggest that post-encoding processes differentially influence face memories from different categories, which may have implications for evaluating face memory in everyday situations.
