This study examined the extent to which different measures of speechreading performance correlated with particular cognitive abilities in a population of hearing-impaired people. Although the 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 age was taken into account, speech tracking correlated primarily with (written) lexical decision speed. In contrast, speechreading for sentence comprehension correlated most strongly with performance on a phonological processing task (written pseudohomophone detection) but also on a span measure that may have utilized visual, nonverbal memory for letters. We discuss the implications of this pattern.
