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.

项目摘要 情感的感知始于情绪检测，这反映了确定是否是否 情绪内容存在。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，要快速的行为响应。情绪检测（及其与直接威胁的关系） 主要是成年人研究的，对这种关键能力的发展知之甚少。 该提案的K99部分试图通过测试婴儿检测情感内容来记住情况 在非常简短的刺激演示中（50ms，100ms，200ms，400ms）。婴儿将使用快乐测试， 生气，恐惧的面部表情和对不同情感的扫视延迟将确定他们是否是否 被差异检测到；具体而言，如果与非非 - 威胁情绪（幸福）。此外，眼睛跟踪和化学测量措施将决定是否确定 婴儿正在利用特定特征来检测不同的情绪，以及瞳孔直径是否 自主神经系统（ANS）功能会因情感面孔而改变。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 在开发中，确定这些是否与后来的发展能力有关。候选人： 候选人拥有她的博士学位在实验心理学中，拥有两年的博士后研究经验。 由于健康问题，她在自己的领域缺席了4年的出版物记录目的地。与此 奖项，她将发挥成功成为成功的独立调查员的潜力。培训：具体 在获得和分析眼睛追踪数据以及相关化学测量方面的培训将是 她在I/博士学位广泛大学的研究中追求终身职位。成为 使用MATLAB舒适并使用高级统计方法进行分析是合适的 培训旨在促进这一目标。 KU的Life Span Institute是一个跨学科研究中心 整个生命周期的发展及其协作环境将为 拟议的研究。研究：使用3.5个月和7.5个月大的婴儿的横断面研究，提议 研究将记录情感检测的时间过程，潜在的优先处理与威胁有关的处理 情绪，低水平的视觉特征影响检测的程度以及ANS活动如何不同地调节 情感内容。 R00阶段将在12.5个月时增加额外的访问，并在18岁时进行后续评估 月份。这项研究将建立跨措施的跨年龄稳定性，并检查其预测有效性 发展结果。记录婴儿早期至关重要技能的发展具有潜力 在典型和非典型发展的研究中的含义，例如自闭症谱系障碍。
