J. Dancer et al., A CROSS-SECTIONAL INVESTIGATION OF SPEECHREADING IN ADULTS - EFFECTS OF AGE, GENDER, PRACTICE, AND EDUCATION, The Volta review, 96(1), 1994, pp. 31-40
The speechreading performance of 50 adults ranging in age from 20-69 w
ith normal hearing and vision was determined using lists A and B of Ha
rris' Revised CID Everyday Sentence Lists. Statistical analysis of the
four variables of age, gender, practice, and education revealed that
females showed significantly higher speechreading scores than did male
s. Further, females improved their performance significantly over the
two trials while males did not. Females in their 30s showed the highes
t performance levels while males in their 60s showed the lowest. Years
of education had no effect on scores. A number of factors, including
caution, visual-neural conduction times, presbyopic changes in vision,
and left-right hemispheric function, may help to explain the present
findings, which have implications for both clinicians and researchers.
