This study examined behaviors reflecting cerebral organization of speaking and singing in normal college students. The investigation focused on whether differences existed in the laterality patterns of two singing tasks and one speaking task in males and females. Performance was measured on a verbal/manual time-sharing paradigm, coupling finger tapping with three vocal tasks (speaking, singing a rote song, singing up and down a diatonic five note scale). Females exhibited less variation than males in mean tapping rates and laterality scores across all three vocal tasks, thus indicating that gender most likely influences lateralization of vocal tasks. Bilateral integration was indicated for both males and females during singing up/down the aforementioned scale. These findings suggest differential involvement of both hemispheres in processing musical functions.
本研究考察了正常大学生中反映言语和歌唱大脑组织的行为。调查聚焦于男性和女性在两项歌唱任务和一项言语任务的偏侧化模式上是否存在差异。通过言语/手动分时范式进行表现测量，将手指敲击与三项发声任务（说话、唱一首死记硬背的歌曲、在自然音阶的五个音符上上下下唱歌）相结合。在所有三项发声任务中，女性的平均敲击速率和偏侧化分数的变化比男性小，因此表明性别很可能影响发声任务的偏侧化。在上述音阶上下唱歌时，男性和女性均表现出双侧整合。这些发现表明，两个半球在处理音乐功能时的参与程度不同。
