Eighteen hearing-impaired subjects participated in the present study. The purpose was to investigate one general question: The nature of the relationship between verbal ability and speechreading. Verbal ability was assessed by two types of measure: a test of vocabulary size, and four tests of lexical access speed. The results demonstrated that lexical access speed was related to speechreading performance. Vocabulary size was not found to be directly related to the speechreading criterion; rather, its influence was in an indirect fashion via its relation to lexical access speed. It was concluded that lexical access speed could be used as a diagnostic tool, such that when an individual demonstrates lexical access that is unreasonably slow, it could be taken as an indication to suggest that rehabilitation programs should emphasize alternatives to speechreading. A general implication of the present results is that absence of relation between a predictor variable and the speechreading criterion does not necessarily imply absence of relation between the two. There is still a possibility that the predictor variable might be indirectly related to the speechreading criterion.
18名听力受损受试者参与了本研究。目的是调查一个一般性问题：言语能力与唇读之间关系的本质。言语能力通过两种测量方式进行评估：词汇量测试和四项词汇提取速度测试。结果表明，词汇提取速度与唇读表现相关。未发现词汇量与唇读标准直接相关；相反，其影响是通过与词汇提取速度的关系以间接方式产生的。得出的结论是，词汇提取速度可用作一种诊断工具，即当个体表现出词汇提取速度异常缓慢时，这可被视为一个迹象，表明康复计划应强调唇读之外的替代方法。本研究结果的一个普遍意义是，预测变量与唇读标准之间缺乏关系并不一定意味着两者之间不存在关系。预测变量仍有可能与唇读标准间接相关。
