In dichotic listening studies, numerous investigators have shown a left ear advantage (i.e., right hemisphere superiority), when judging emotional tone of speech. In the present study, dichotic word-pairs of emotion and non-emotion words were presented to participants who were instructed to recall the entire list in each block. Unlike other studies in which participants responded to emotional intonations, participants in the present investigation listened to stimuli that were spoken in a neutral intonation. A total of 62 participants listened to emotion (e.g., loving) and non-emotion (e.g., combine) words that were dichotically presented. The results showed a left ear advantage for emotion words. This finding provides strong support for the right-hemisphere hypothesis in the form of a stronger memory for emotion words presented to the left ear. The findings are consistent with the role of the right hemisphere in the perception of emotional information.
在双耳分听研究中,众多研究者发现,在判断言语的情感基调时,存在左耳优势(即右半球优势)。在本研究中,向参与者呈现情感词和非情感词的双耳词对,并要求他们在每个组块中回忆整个列表。与其他要求参与者对情感语调做出反应的研究不同,本研究中的参与者听取的是用中性语调说出的刺激。共有62名参与者听取了以双耳分听方式呈现的情感词(如“爱意”)和非情感词(如“组合”)。结果显示,情感词存在左耳优势。这一发现为右半球假说提供了有力支持,表明对呈现给左耳的情感词有更强的记忆。这些发现与右半球在情感信息感知中的作用相一致。
