A VISUAL LETTER-IDENTIFICATION TASK WHICH CORRELATES WITH SPEECHREADING ABILITY
GA DAY, JS FINNIGAN, Stuart Gatehouse · 2024
Correlations have been reported between speechreading scores and many visual attributes.including pattern recognition and latency of visual evoked potentials.Many such attributes must combine to determine an individual's ability as a speechreader.so any comprehensive assessment of speechreading aptitude should reflect at least some of these attributes.A fundamental model of speechreading has been used to design a test which aims to reflect the overall potential of an individual to perfonm speechreading tasks.The test involves speed of perception and pattern recognition and is contained in a microcomputer program: it is quick and easy to perform; Results are reported from 18 severely hearing impaired subjects.This homogeneous group was not selected to maximise the variance in speechreading skills.but to reflect the constraints in a relevant target population.Nevertheless a significant correlation (-0.73) was found between the test score and speechreading as assessed with a video based sentence test.After the removal of subjects' age.hearing level.visual acuity and I.Q.as co-variates.the correlation remains.
