This investigation is a follow-up to a longitudinal speech and educational outcome study involving approximately 400 normally developing children that was initiated in 1960. From this database, two groups of subjects (now aged 32-34), their spouses, and all of their offspring over the age of 3:0 (years:months) completed a battery of cognitive-linguistic and interview measures. One group (probands) consisted of 24 adults with a documented history of a moderate phonological-language disorder that persisted through at least the end of the first grade. The other group (controls) consisted of 28 adults who were known to have had normal articulation abilities as children. Results of this study demonstrated that, in comparison to the children of controls, the children of the proband subjects performed significantly more poorly on all tests of articulation and expressive language functioning and were significantly more likely to have received articulation treatment. There was, however, no evidence that specific misarticulations or phonological processes traveled within proband families. These results are in agreement with those of most previous family studies that have demonstrated an increased rate of occurrence of speech-language disorders of unknown origin in families including a first-degree relative who is similarly affected.
本调查是一项针对纵向言语和教育成果研究的后续研究，该纵向研究始于1960年，涉及约400名正常发育儿童。从这个数据库中，两组受试者（现年龄为32 - 34岁）、他们的配偶以及所有3岁0个月及以上的后代完成了一系列认知语言和访谈测量。一组（先证者）由24名成年人组成，他们有中度语音语言障碍的记录，这种障碍至少持续到一年级末。另一组（对照组）由28名成年人组成，已知他们在儿童时期有正常的发音能力。这项研究的结果表明，与对照组的孩子相比，先证者受试者的孩子在所有发音和表达语言功能测试中的表现明显更差，并且明显更有可能接受过发音治疗。然而，没有证据表明特定的发音错误或语音过程在先证者家庭中传播。这些结果与大多数先前的家庭研究结果一致，这些研究表明，在包括一名同样受影响的一级亲属的家庭中，不明原因的言语语言障碍的发生率有所增加。
