精神分裂症严重的个体已被证明言语处理的偏侧化减少，这可能受到左半球功能受损的影响。然而，人们对精神分裂和情绪感知等右半球功能知之甚少。本研究的重点是冲动性不顺从（IMP）中语言和情感韵律的非典型偏侧化，这是精神分裂症的一个特定方面。共有 41 名参与者（20 名女性）执行了双耳听力语言和情感韵律任务，通常分别显示右耳优势 (REA) 和左耳优势 (LEA)。根据牛津-利物浦情感和体验清单中包含的 IMP 量表进行中值分割，将样本分为高分和低分。结果表明，高 IMP 男性的韵律任务中 LEA 选择性降低。 IMP 高和低的女性在这两项任务中都表现出典型的偏侧化。结果表明，高 IMP 男性特别容易出现情绪韵律的非典型偏侧化，这与男性精神分裂症患者的发现相似。结果表明，精神分裂症和精神分裂症之间的性别特异性非典型大脑组织具有相似性。
Individuals high in schizotypy have been shown to reveal reduced lateralisation in verbal processing which may be influenced by an impaired left hemisphere performance. However, little is known about schizotypy and right hemisphere functions such as emotional perception. The present study focuses on atypical lateralisation in language and emotional prosody in Impulsive Non-conformity (IMP), a specific aspect of schizotypy. A total of 41 participants (20 females) performed a dichotic listening linguistic and emotional prosody task, which typically shows a right ear advantage (REA) and left ear advantage (LEA), respectively. A median split based on the IMP scale included in the Oxford-Liverpool Inventory of Feelings and Experiences was used to divide the sample into high and low scorers. The results revealed a selective reduction of the LEA in the prosody task in high-IMP males. Females high and low in IMP revealed typical lateralisation in both tasks. The results indicate that high-IMP males are especially prone to atypical lateralisation in emotional prosody, which parallels those findings in male patients with schizophrenia. The results suggest similarities in sex-specific atypical brain organisation between schizotypy and schizophrenia.
