Guessing and speechreading

Abstract
The present experiment investigated the relation between guessing (cf. synthetic ability, Jeffers and Barley, 1971) and speechreading performance. Guessing was measured by two types of completion tests: One sentence-completion test (SCT), and one word-completion test (WCT). The results indicated that skilled guessing—in terms of SCT-performance — proved to be critical for longer sentences to be speechread, while skilled guessing — as measured by a WCT — proved to be critical for speechreading situations where a low level of contextual information was offered. The latter result was also obtained for one of the SCT-subtests. The results suggest that speechreading and guessing skill are related to each other, and that different types of guessing tests predict different aspects of the speechreading process.
