Face likeability mediates the memory-enhancing effect of face attractiveness in young but not older adults

Evidence of effects of face attractiveness on memory is mixed and little is known about the underlying mechanisms of this relationship. Previous work suggests a possible mediating role of affective responding to faces (i.e., face likeability) on the relationship between face attractiveness and memory. Age-related change in social motivation may reduce the relevance of face attractiveness in older adults, with downstream effects on memory. In the present study, 50 young and 51 older participants were presented with face-trait pairs. Faces varied in attractiveness. Participants then completed a face-trait associative recognition memory task and provided likeability ratings for each face. There was a memory-enhancing effect of face attractiveness in young (but not older) participants, which was partially mediated by face likeability. In addition, more attractive and less attractive (compared to moderately attractive) faces were more likely remembered by both young and older participants. This quadratic effect of face attractiveness on memory was not mediated by face likeability. Findings are discussed in the context of motivational influences on memory that vary with age.     

换脸术几个问题的理性思考

换脸术是目前国内外争论的一个焦点,是异体器官移植领域内新的突破,为严重毁容患者带来了重新获得美容的希望。但是目前还有很多问题需要进一步。在远期疗效尚未肯定的情况下,作为医务工作者,我们需要加强自身修养和伦理道德教育,做出正确的决定,并不断进行相关研究,最终广泛应用于临床,造福于人类。     

面孔吸引力观察者参照:“角度效应”的眼动研究

以标准的黑白面孔图片作为实验材料,让41名大学生观看不同倾斜角度(左倾、竖直和右倾)的面孔图片,并对之进行面孔吸引力的评价,同时用眼动仪记录被试的眼动数据。结果显示:(1)被试观看左倾和右倾面孔的平均瞳孔大小显著小于观看竖直面孔的平均瞳孔大小,观看左倾面孔的平均瞳孔大小显著大于右倾面孔;(2)被试对左倾和右倾面孔的平均注视时间显著短于对竖直面孔的平均注视时间,同时对左倾面孔的注视时间显著长于右倾面孔;(3)被试对左倾和右倾面孔的平均注视次数显著少于对竖直面孔的平均注视次数。实验结果表明,面孔的倾斜角度很可能是影响面孔吸引力的一个重要因素,在面孔吸引力的审美偏好中存在"角度效应",即竖直面孔的吸引力高于倾斜面孔的吸引力,左倾面孔的吸引力高于右倾面孔的吸引力。     

面孔吸引力和信息正确性对幼儿选择性信任的影响

实验1采用3×2×2 的混合设计, 考察4~6岁幼儿获取全新信息时基于面孔吸引力的选择性信任及其特点。结果显示：(1) 4~6岁的男孩和女孩均表现出对高面孔吸引力者的选择性信任。(2)在选择性信任程度方面：5岁比4岁高, 而4岁和6岁之间、5岁和6岁之间则相同; 女孩在询问任务中比男孩表现出更高的选择性信任, 在赞同任务中则相同。那么, 幼儿的这种选择性信任是否受到信息正确性的调节?为此, 实验2采用2×3的被试间设计, 探讨信息提供者提供信息的正确性对4~6岁幼儿基于面孔吸引力的选择性信任的影响。结果显示：在正确性为50% vs. 50%条件下, 幼儿未对信息提供者产生选择性信任; 在正确性为25% vs. 75%条件下, 幼儿对提供较大正确性信息的低面孔吸引力者产生了选择性信任。研究结果表明：(1)在信息缺乏时, 4~6岁幼儿普遍存在有偏见的选择性信任; 女孩比男孩更易受到社会偏见因素的影响。(2)在信息明确时, 4~6岁幼儿也能做出相对理性的选择性信任。     

Facial attractiveness impressions precede trustworthiness inferences: lower detection thresholds and faster decision latencies

Prior research has found a relationship between perceived facial attractiveness and perceived personal trustworthiness. We examined the time course of attractiveness relative to trustworthiness evaluation of emotional and neutral faces. This served to explore whether attractiveness might be used as an easily accessible cue and a quick shortcut for judging trustworthiness. Detection thresholds and judgment latencies as a function of expressive intensity were measured. Significant correlations between attractiveness and trustworthiness consistently held for six emotional expressions at four intensities, and neutral faces. Importantly, perceived attractiveness preceded perceived trustworthiness, with lower detection thresholds and shorter decision latencies. This reveals a time course advantage for attractiveness, and suggests that earlier attractiveness impressions could bias trustworthiness inferences. A heuristic cognitive mechanism is hypothesised to ease processing demands by relying on simple and observable clues (attractiveness) as a substitute for more complex and not easily accessible information (trustworthiness).     

Evaluations versus stereotypes in emotion recognition: a replication and extension of Craig and Lipp’s (2018) study on facial age cues

Recently, Cognition and Emotion published an article demonstrating that age cues affect the speed and accuracy of emotion recognition. The authors claimed that the observed effect of target age on emotion recognition is better explained by evaluative than stereotype associations. Although we agree with their conclusion, we believe that with the research method the authors employed, it was impossible to detect a stereotype effect to begin with. In the current research, we successfully replicate previous findings (Study 1). Furthermore, by changing the comparative context, Study 2 provides a first test of age-stereotypes affecting emotions recognition. We discuss recommendations for future studies in the domain of social categorisation and emotion recognition.     

表情对婴儿面孔图式效应的调节及其机制

婴儿面孔图式效应是促进早期亲子关系形成的一种先天本能反应, 该效应一直被认为主要是受婴儿面孔结构的影响。但近年来表情对该效应的影响开始得到关注, 在以成人面孔为基线的条件下, 婴儿面孔图式效应量会因表情不同而有所变化, 表现出中性婴儿面孔图式效应最强的现象。鉴于目前对该现象的成因及其神经机制知之甚少, 所以本项目拟先建立一套婴儿与成人同面孔多表情图片系统; 然后以此为基础, 分别考察面孔表情不确定性是否会调节成人对不同表情婴儿面孔的偏好和注意偏向, 并探究其相应神经机制, 促进养育脑研究在我国的开展。     

Facial gender confirmation surgery—review of the literature and recommendations for Version 8 of the WPATH Standards of Care

Facial gender confirmation surgery (FGCS), also popularly known and referred to in the scientific literature as facial feminization surgery (FFS), was previously treated as a collection of aesthetic procedures complementing other aspects of gender-confirming surgery. Recent literature on quality-of-life outcomes following FGCS has supported the substantial impact these procedures have on overall well-being and reduction of psychosocial sequelae in patients. The World Professional Association for Transgender Health Standards of Care, Version 7 (WPATH SOC 7), did not deem FGCS a medical necessity. Based on these new studies, increasing evidence points to the need to include FGCS among medically necessary gender-confirming surgeries, though more-prospective studies are needed. Updates to the WPATH SOC 8 are proposed based on available quality of life studies.     

女性面孔吸引力的加工及其对男性诚实道德行为的影响:一项ERP研究

研究考察了不同女性面孔吸引力情境对男性被试诚实道德决策行为的影响,同时采用ERP技术对社会情境中面孔吸引力的信息加工方式特点进行探究。结果发现,高面孔吸引力记录员情境中被试倾向更加真实地报告自己的预测结果而表现出更多诚实的道德决策;ERP结果则发现高吸引力记录员面孔较之于低吸引力记录员面孔在反应提示界面在大脑中后部诱发更大的早期N200成分。结果提示,在与面孔审美评价无关的社会情境中个体面孔的吸引力信息能够被快速识别与自动化加工,同时也会直接促进他人自身的道德行为水平。
