Investigated 6 girls with Rett syndrome (RS), ages between 2 and 13 years, to provide comprehensive descriptions of their communicative behaviors. Previous studies have not focused on communicative competence nor on the intentionality of the language used by children with RS. This study concluded that all members of the group investigated were at a preintentional level of communication. Intentional communication has previously been reported to develop in normally developing and intellectually disabled children attaining Piagetian Sensorimotor Stage V in Means-End behavior. The present study also investigated the cognitive performance of the group. We concluded that the preintentional level of communication noted was consistent with the subjects' profound intellectual disability. No Means-End (i.e., purposeful) behavior beyond Piagetian Sensorimotor Stage III could be elicited from the 6 girls. The relevance of this study for therapeutic intervention is discussed.
对6名年龄在2至13岁之间的雷特综合征（RS）女童进行了调查，以全面描述她们的交流行为。以往的研究既没有关注交流能力，也没有关注雷特综合征患儿所使用语言的意图性。本研究得出结论，所调查的这组女童均处于前意图性交流水平。此前有报道称，正常发育和智力残疾儿童在手段 - 目的行为中达到皮亚杰感觉运动阶段V时会发展出意图性交流。本研究还调查了该组女童的认知表现。我们得出结论，所观察到的前意图性交流水平与受试者的重度智力残疾是一致的。这6名女童无法表现出超出皮亚杰感觉运动阶段III的手段 - 目的（即有目的的）行为。文中讨论了本研究对于治疗干预的相关性。
