FAMILIALITY OF SEVERE PHONOLOGY DISORDERS: READING DISORDERS & SEGREGAT ANALYSIS

研究正常和无序的音系学需要测量 从生物语言学角度来说，言语产出是合适的 心理测量学很强健。一些语音和韵律声音 已经专门开发了用于基因研究的方法 以及在其他发展音系学的描述性研究中 精神错乱。这10项衡量发音能力的指标 会话演讲，从5-10分钟内获得 对话语音样本，已经根据以下方面进行了评估 可靠性和寿命参考数据，并构成临床的一部分 名为言语障碍分类的分类工具 系统(SDCS)。这一分类包括一些描述性的 亚型，包括没有言语障碍的人，那些 言语障碍已经正常化，在那些有发育障碍的人中 语音障碍，分成言语迟缓个体 和那些持续的、残留的错误持续到第九个之后 年，并可能进行其他改进。这些指标一直是 为核心家庭成员通过 患有严重语音障碍的学龄前儿童。当前的努力 重点将这些指标和子类型与其他标准进行比较 言语和语言的衡量标准。对这些的综合分析 对通过幼儿园确诊的家庭儿童采取的措施 患有语言障碍的儿童没有证据表明 发行版，而不是单一的发行版，提供了更好的 与数据相适应。

Research in normal and disordered phonology requires measures of speech production that are biolinguistically appropriate and psychometrically robust. A number of speech and prosody-voice measures have specifically been developed for use in genetic studies and in other descriptive studies of developmental phonological disorders. These 10 metrics of articulation competence in conversational speech, which are obtained from a 5-10 minute conversational speech sample, have been evaluated in terms of reliability and life span reference data, and form part of a clinical classification instrument titled the Speech Disorders Classification System (SDCS). This classification includes a number of descriptive subtypes, including individuals without speech disorders, those whose speech disorders have normalized, and, among those with developmental phonological disorders, subgroupings into speech delayed individuals and those with persistent, residual errors persisting beyond the ninth year, with other refinements possible. These metrics have been obtained for members of nuclear families ascertained through a preschool child with a severe phonologic disorder. Current efforts focus on comparisons of these metrics and subtypes with other standard measures of speech and language. Commingling analyses of these measures in children from families ascertained through a preschool child with a language disorder showed no evidence that a mixture of distributions, rather than a single distribution, provided a better fit to the data.
