情绪被认为是存储在长期记忆的基础上的功能作为一个记忆单位的对象。以前的研究表明，语言特征分层代表情绪，如悲伤。虽然情绪与语言和非语言特征有关，但这些特征在情绪的记忆表征中是如何相互关联的尚不清楚。我们假设，一些非言语功能的层次功能作为“上级”或“下级”的感官知觉的维度表示情绪对应的言语功能。以悲伤情绪为目标情绪，进行了一个图片词一致性判断实验。本研究使用了16张身体表情照片（四水平躯干倾斜×四水平手臂姿势）作为感官知觉特征，并使用了32个与哭泣相关的词语作为原型代表悲伤的言语特征。48名参与者评估了身体表情图片和哭泣相关词汇之间的所有组合的一致性。使用网络图分析，身体表情被分为三个社区的一致性评级的基础上：占主导地位的身体表达社区表现出最高的口头一致性组成的眼睛周围和全面面对手臂的姿势，无论躯干倾斜。在这个占主导地位的社区，躯干倾斜度从属调制图片-单词一致性根据身体激活属性。这些研究结果支持基于特征的情感表征，通过相应的层次结构之间的语言和非语言功能。
Emotions are thought to be stored in long-term memory based on features as a memory unit of objects. Previous studies suggest that verbal features hierarchically represent emotions, such as sadness. Although emotion is associated with verbal and nonverbal features, it is not clear how these features interrelate in the memory representation of emotion. We hypothesized that some nonverbal features hierarchically function as “superordinate” or “subordinate” in sensory-perceptual dimensions representing emotions corresponding with verbal features. We focused on sadness as a target emotion and conducted a picture-word congruency judgment experiment. This study used 16 bodily-expression photographs (four-level trunk inclinations × four-level hand-arm postures) as sensory-perceptual features and 32 crying-related words as verbal features that prototypically represent sadness. Forty-eight participants assessed congruency concerning all combinations between bodily-expression pictures and crying-related words. Using a network graph analysis, bodily expressions were classified into three communities based on congruence ratings: the dominant bodily-expression community showed the highest verbal congruency composed of around-eye and overall-face hand-arm postures, irrespective of trunk inclination. Within this dominant community, trunk inclination subordinately modulated picture-word congruency according to bodily-activation properties. These findings support a feature-based representation of emotion through corresponding hierarchical structures between verbal and nonverbal features.
