The spontaneous conversational speech of 20 children with unilateral left hemisphere lesions and 13 with right lesions was compared to normally developing peers matched by age, sex, race, and social class for instances of stuttering type nonfluencies, normal nonfluencies, and rate of speech. Both left and right lesioned children provided quantitatively more and qualitatively different patterns of nonfluencies than their neurologically normal peers. Left and right lesioned children produced more stuttering types of nonfluencies than their controls, but neither lesioned group produced a greater number of normal nonfluencies than controls. Left lesioned children also had a slower rate of speech as measured by number of syllables per second during either stuttered or fluent speech. Considerable variability was observed among lesioned children. Implications for neurogenic theories of developmental fluency disorders are discussed.
将20名单侧左半球损伤儿童和13名右侧损伤儿童的自发对话言语，与年龄、性别、种族和社会阶层相匹配的正常发育同龄人进行比较，以观察口吃型不流畅、正常不流畅和语速的情况。与神经功能正常的同龄人相比，左侧和右侧损伤儿童在不流畅的数量和质量模式上都更多且不同。左侧和右侧损伤儿童产生的口吃型不流畅比对照组更多，但两组损伤儿童产生的正常不流畅数量都不比对照组多。通过口吃或流畅言语期间每秒的音节数衡量，左侧损伤儿童的语速也较慢。在损伤儿童中观察到了相当大的变异性。讨论了对发育性流畅障碍神经源性理论的启示。
