本研究提出了与自闭症儿童表达语言中的韵律异常相关的假设。我们采用操作型范式来衡量一个口头呈现的故事对自闭症、智力障碍和正常人群的内在强化价值，并控制了时间年龄和表现心理年龄。结果表明，自闭症儿童和弱智儿童都能感知韵律线索，尽管只有弱智儿童能够用他们的表达语言来使用它们。研究还表明，与正常儿童相比，语言刺激对自闭症和弱智儿童的内在强化价值可能较小。对未来研究和治疗的意义进行了讨论。
The present study pursued hypotheses relevant to prosodic abnormalities in the expressive language of autistic children. An operant paradigm was employed to measure the intrinsic reinforcing value of a verbally presented story for autistic, mentally retarded, and normal groups controlling for chronological age and performance mental age. Results suggested that both autistic and mentally retarded children could perceive prosodic cues, although only mentally retarded children are able to use them in their expressive language. It was also suggested that linguistic stimuli may have less intrinsic reinforcement value for autistic and mentally retarded children than for normal children. Implications for future research and treatment were discussed.
