Acoustic Image in Visual Detection for Deaf and Hearing College Students

Abstract

To explore the role of acoustic factors in visual detection, this study employed 40 deaf and hearing Ss. Ss were requested to cancel all the letters "e" in a passage from Treasure Island. Results were analyzed in terms of probabilities of missing a pronounced or silent e and the e in the word "the." Hearing and hard of hearing Ss were more likely to miss silent e's than pronounced e's. There was no significant difference between silent and pronounced e's for the profoundly deaf. Deaf and hearing Ss missed significantly more e's in "the" than pronounced or silent e's. The deaf, when compared to the hearing Ss, were more efficient in detecting pronounced and silent e's. They did not differ significantly from the hearing Ss in detecting the e in "the."
