In this preliminary study, hemispheric specialization for the experience and expression of emotion was investigated. Subjects were right-brain-damaged (RBD), left-brain-damaged (LBD), and normal control (NC) right-handed adults, carefully matched on demographic and neurological variables. Facial expressions were videotaped while subjects described recollected emotional and nonemotional experiences. Expressions were later rated by trained judges for emotional intensity and category accuracy. To examine experience, subjects evaluated the intensity and accuracy with which they had produced their monologues. RBDs produced less intense facial expressions and reported less intense emotional experiences than LBDs and NCs. LBDs rated themselves as producing expressions with less accuracy than did RBDs and NCs. These findings are consistent with research that supports the right-hemisphere hypothesis for emotion. In addition, judges' ratings and subjects' self-reports of emotional intensity were positively correlated for normal but not for brain-damaged subjects.
在这项初步研究中，对情感体验和表达的半球特化进行了调查。研究对象为右脑损伤（RBD）、左脑损伤（LBD）和正常对照（NC）的右利手成年人，他们在人口统计学和神经学变量上经过仔细匹配。当研究对象描述回忆起的情感和非情感经历时，对他们的面部表情进行录像。之后，由训练有素的评判员对面部表情的情感强度和类别准确性进行评分。为了检验情感体验，研究对象对他们独白的强度和准确性进行评估。与LBD组和NC组相比，RBD组产生的面部表情强度较低，且报告的情感体验强度也较低。LBD组认为自己产生的表情准确性低于RBD组和NC组。这些发现与支持情感右半球假说的研究一致。此外，对于正常受试者，评判员的评分与研究对象对情感强度的自我报告呈正相关，但对于脑损伤受试者则不然。
