A review of experimental and theoretical works upon perception of emotions in speech is introduced. The main approaches to experimental study and different types of stimulation are considered. Clinical research and experiments upon healthy subjects investigate the brain organization of emotional speech recognition. In the works by Rusalova, Kislova integral psychophysiological preconditions for the successfulness of the recognition of speech emotional expression were studied. As a result of the investigation, extreme groups of persons were identified: with high indices of "emotional hearing" and with low level of recognition of emotions. Analysis of EEG included comparison of different EEG parameters between two groups: values of EEG power, the dominating frequencies, percentage of different EEG-bands in the summary EEG power, coherence, values of EEG inter- and intra-hemispheric asymmetry, etc. The subjects with low identification rates showed a higher brain activation and reactivity both during the emotion identification task and at rest as compared to the subjects with high identification rates. The data obtained reveal specific activation within the left frontal regions, as well as the right posterior temporal cortex during nonverbal recognition of emotions.
本文介绍了对言语中情感感知的实验和理论研究工作的综述。考虑了实验研究的主要方法和不同类型的刺激。针对健康受试者的临床研究和实验探究了情感语音识别的大脑组织。在鲁萨洛娃、基斯洛娃的研究中，研究了语音情感表达识别成功的整体心理生理前提条件。调查结果确定了极端人群：“情感听力”指数高的人群和情感识别水平低的人群。脑电图分析包括两组之间不同脑电图参数的比较：脑电图功率值、主导频率、总脑电图功率中不同脑电图频段的百分比、相干性、脑电图半球间和半球内不对称值等。与识别率高的受试者相比，识别率低的受试者在情感识别任务期间和休息时均表现出更高的大脑激活和反应性。获得的数据揭示了在情感非语言识别过程中左额叶区域以及右后颞叶皮质内的特定激活。
