项目摘要

Project Summary The perception of emotion starts with emotion detection, which reflects an ability to determine whether emotional content is present. The detection of emotional information is evolutionarily relevant, in that it allows for a rapid behavioral response when faced with threat. Emotion detection (and its relation to immediate threat) has primarily been studied with adults and very little is known about the development of this critical ability. The K99 portion of this proposal seeks to remedy the situation by testing infants for detection of emotional content in very brief stimulus presentations (50ms, 100ms, 200ms, 400ms). The infants will be tested using happy, angry, and fearful facial expressions and saccade latencies to different emotions will establish whether they are differentially detected; specifically, if threat-related emotions (i.e., anger, fear) are detected faster than non- threatening emotion (happiness). Additionally, eye-tracking and pupillometry measures will determine whether infants are utilizing specific features to detect distinct emotions and whether pupil diameter, an index of autonomic nervous system (ANS) function, is altered by emotional faces. Most importantly, the R00 phase of this award will be used to study a longitudinal sample to assess individual differences in detection speed across development and determine whether these relate to later developmental abilities. Candidate: The candidate has her Ph.D. in Experimental Psychology and has 2 years of postdoctoral research experience. She has a strong publication record despite a 4-year absence from her field due to health issues. With this award, she will reach her potential to become a successful independent investigator. Training: Specific training in the acquisition and analyses of eye-tracking data and the related measures of pupillometry will be useful in her pursuit of a tenure-track position at a Research I/Doctorate Extensive university. Becoming comfortable using MATLAB and conducting analyses using advanced statistical methods will be appropriate training aims to facilitate this goal. KU’s Life Span Institute is an interdisciplinary research center focused on development across the life span, and its collaborative environment will provide an ideal setting for the proposed research. Research: Using a cross-sectional study with 3.5- and 7.5-month-old infants, the proposed research will document the time course of emotion detection, potential preferential processing of threat-related emotions, how low-level visual features influence detection, and how ANS activity is differentially modulated by emotional content. The R00 phase will add an additional visit at 12.5 months and a follow-up assessment at 18 months. This study will establish cross-age stability across measures and examine their predictive validity for developmental outcomes. Documenting the development of this vital skill in early infancy has potential implications in the study of typical and atypical development, such as that in autism spectrum disorder.

项目概要对情绪的感知始于情绪检测，情绪检测反映了判断情绪是否存在的能力。情感内容是存在的。情感信息的检测在进化上是相关的，因为它允许。面对威胁时快速的行为反应（及其与直接威胁的关系）。主要是针对成年人进行的研究，但人们对这种关键能力的发展知之甚少。该提案的 K99 部分旨在通过测试婴儿的情绪内容来纠正这种情况在非常简短的刺激演示中（50 毫秒、100 毫秒、200 毫秒、400 毫秒），婴儿将使用 happy、愤怒和恐惧的面部表情以及对不同情绪的扫视潜伏期将确定他们是否被区别地检测到；具体来说，是否与非威胁相关的情绪（即愤怒、恐惧）被检测得更快此外，眼动追踪和瞳孔测量将决定是否存在威胁情绪。婴儿正在利用特定的特征来检测不同的情绪和瞳孔直径，这是一个指数自主神经系统 (ANS) 功能会因情绪面孔而改变，最重要的是，R00 阶段。该奖项将用于研究纵向样本，以评估检测速度的个体差异跨越发展并确定这些是否与以后的发展能力相关。候选人拥有实验心理学博士学位，并拥有 2 年博士后研究经验。尽管由于健康问题她离开了自己的领域四年，但她仍然保持着良好的发表记录。获奖后，她将发挥成为一名成功的独立调查员的潜力：特定培训。将进行眼动追踪数据采集和分析以及瞳孔测量相关测量方面的培训这对于她在研究型大学/博士生大学寻求终身职位很有帮助。熟练使用 MATLAB 并使用高级统计方法进行分析将是适当的 KU 的生命周期研究所是一个专注于这一目标的跨学科研究中心。整个生命周期的发展及其协作环境将为拟议的研究：对 3.5 个月和 7.5 个月大的婴儿进行横断面研究。研究将记录情绪检测的时间过程、与威胁相关的潜在优先处理情绪、低级视觉特征如何影响检测，以及 ANS 活动如何受到不同因素的差异调节 R00 阶段将在 12.5 个月时增加一次额外访问，并在 18 个月时进行后续评估。这项研究将建立跨年龄的稳定性，并检验其预测有效性。记录婴儿早期这一重要技能的发展具有潜力。对典型和非典型发展研究的影响，例如自闭症谱系障碍。
