This study examined the extent to which different measures ofspeechreading performance correlated with particular cognitiveabilities in a population of hearing-impaired people. Althoughthe three speechreading tasks (isolated word identification,sentence comprehension, and text tracking) were highly intercorrelated,they tapped different cognitive skills. In this population,younger participants were better speechreaders, and, when agewas taken into account, speech tracking correlated primarilywith (written) lexical decision speed. In contrast, speechreadingfor sentence comprehension correlated most strongly with performanceon a phonological processing task (written pseudohomophone detection)but also on a span measure that may have utilized visual, nonverbalmemory for letters. We discuss the implications of this pattern.
