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.

尽管有很多研究证明边缘系统 情绪的基质，也有新的证据表明， 新皮层在情绪处理中的特殊作用。 主要 目前项目的目的是测试目前的概念， 神经心理学的新皮质处理情绪在五个领域： 大脑半球特化，情绪效价，加工模式， 表达类型和沟通渠道。 关于大脑半球间的特化和效价的假设， 测试：（a）右半球的情绪优势，无论 效价;（B）右半球对消极情绪的支配，左半球对消极情绪的支配。 积极情绪的半球优势;（c）右半球 主导的感知情绪的效价和 表达的差异优势作为化合价的函数。 作为加工模式的函数，半球内特化也 将被解决，以确定是否感知是独立的， 情绪表达，与“前”皮层区域相关， 表达和“后”区与知觉。 更多地了解 表达行为背后的神经系统，包括姿势和 自然的表情就会被激发出来。 最后，三个渠道 沟通（面部，韵律，词汇）将被检查，以评估 在多大程度上有一个单一的系统， 处理. 受试者将有48名右脑受损，48名左脑受损， 正常对照右利手男性和女性。 脑损伤患者 将包括前部或后部皮质病变。 为 感知，受试者将识别面部表情的照片， 录音的吟诵句子，和书面刺激传达的感情。 为了表达，将对受试者进行录像、录音和转录 当摆姿势，重温情感体验， 充满感情的幻灯片 非情绪任务也将被管理 控制认知、知觉和运动因素， 在情绪处理任务上的混乱表现。 该项目的一个重要最终产品将是一个广泛的电池， 客观评估大脑中情绪的定量措施- 受损的人口。
