Although there has been much research documenting the limbic system as the substrate for emotion, there is also new evidence indicating a special role for the neocortex in emotional processing. The main purpose of the current project is to test current notions regarding the neuropsychology of neocortically-processed emotion within five domains: hemisphere specialization, emotional valence, processing mode, expression type, and communication channel. Hypotheses regarding interhemispheric specialization and valence will be tested: (a) right hemisphere dominance for emotion, regardless of valence; (b) right hemisphere dominance for negative emotions and left hemisphere dominance for positive emotions; and (c) right hemisphere dominance for the perception of emotions of both valences and differential dominance for expression as a function of valence. Intrahemispheric specialization as a function of processing mode also will be addressed to determine whether perception is independent from expression of emotion, with "anterior" cortical regions associated with expression and "posterior" regions with perception. To learn more about the neural systems underlying expressive behavior, both posed and spontaneous expressions will be elicited. Finally, three channels of communication (facial, prosodic, lexical) will be examined to evaluate the extent to which there is a unitary system underlying emotional processing. Subjects will be 48 right brain-damaged, 48 left brain-damaged, and 48 normal control right-handed males and females. Brain-damaged patients with anterior or posterior cortical lesions will be included. For perception, subjects will identify photographs of facial expressions, recordings of intoned sentences, and written stimuli conveying feelings. For expression, subjects will be videotaped, audiotaped, and transcribed while posing, reliving emotional experiences, and responding to emotionally-laden slides. Nonemotional tasks will also be administered to control for cognitive, perceptual, and motoric factors that might confound performance on tasks of emotional processing. An important end-product of this project will be an extensive battery of quantitative measures for the objective assessment of emotion in brain- damaged populations.

尽管已经有很多研究将边缘系统记录为 情绪的底物，也有新的证据表明 大脑皮层在情绪处理中的特殊作用。主 当前项目的目的是测试当前关于 新皮质加工情绪在五个领域的神经心理学： 大脑半球特化，情绪效价，加工模式， 表达类型、沟通渠道。 关于半球间专门化和价态的假设将是 测试：(A)右脑对情绪的优势，无论 (B)右脑支配负面情绪，左脑占优势 大脑半球支配积极情绪；和(C)右脑 情绪知觉的主导性 作为价态函数的表达的差异显性。 作为加工模式的函数的大脑半球内特化也 以确定知觉是否独立于 情绪表达，与“前部”皮质区域相关 表情和有知觉的“后方”区域。要了解更多关于 表情行为背后的神经系统，既有姿势的，也有 将会引发自发的表情。最后，三个渠道 将检查交流(面部、韵律、词汇)以评估 在多大程度上，情绪背后有一个单一的系统 正在处理。 受试者将有48名右脑受损，48名左脑受损，48名 正常对照右撇子男性和女性。脑损伤患者 有前部或后部皮质损害的患者将被包括在内。为 感知，受试者将识别面部表情的照片， 语调句子的录音，以及传达情感的书面刺激。 对于表达，受试者将被录像、录音和转录 同时摆姿势，重温情感体验，回应 充满感情的幻灯片。非情绪化的任务也将被执行 控制可能存在的认知、知觉和动力因素 在情绪处理任务上表现混乱。 该项目的一个重要最终产品将是一系列广泛的 客观评估大脑情绪的量化方法-- 受损的人口。
