This study compared visual word recognition (speechreading) in video sequences showing either full face or lips plus mandible to 26 normal hearing college students and 4 adults with bilateral sensorineural hearing loss. Percent phoneme correct scores were similar in the two conditions and scores significantly improved for the repeated measure in…

To investigate sensory dominance in early development, a series of studies examined six-month-old infants' processing of multisensory stimulus compounds. Findings indicated that infants discriminated changes in the temporal characteristics of the auditory component but not in the visual component. This and other findings suggested that auditory…

Involving 10-month-old infants, a series of studies examined responses to temporally modulated compound auditory-visual stimuli. Findings indicated that, although the auditory modality can dominate the visual modality at 10 months of age, the visual modality can process temporal information when the temporal relationship of the information in the…

This study examined effects of visual impairment on the performance of typical educational tasks requiring visual accommodation to print material at three different distances. Subjects were 18 visually impaired and 19 nonimpaired children (ages 6-10). Findings indicated that visually impaired children exhibited more fixation shifts per task.…

This study investigated associations between infants' prelinguistic communicative behaviors at 9 months and their communication and language performance at 12 and 18 months. The inclusion of both hearing (N=19) and deaf (N=16) infants in the study allowed identification of effects related to the receptive communication modality (vision versus…
