This study was part of a longitudinal investigation of the impact of deafness on the cognitive, social, and communicative development of infants. The current study reports analyses of the vocalizations of deaf and hearing infants and their Deaf or hearing mothers during normal face-to-face interactions when the infants were 9 months old. Results indicate essentially no differences in the amount of positive or negative vocalizations emitted by infants in any of the four groups observed. However, there is a heightened use of vocal games by hearing mothers interacting with deaf infants, indicating that these mothers are incorporating several additional sensory modalities into their vocal expressions. This is interpreted as one way in which parents make their vocal communication more salient and accessible to an infant with a hearing loss. Deaf mothers are also highly active and engaged with their infants, but have been found to rely more extensively on vigorous tactile contact rather than auditory input during these same interactions.

The authors examine the effects that result when 9-month-old deaf and hearing infants break eye contact during face-to-face interactions with their deaf or hearing mothers. Of particular interest are mothers' responses when their infant looks away, and mothers' degree of success at regaining visual attention by using active bids in either the tactile, visual, or auditory modes. The authors also examine instances of maternal observing and waiting for the infant to reinitiate visual contact. For deaf infants, visual and tactile modalities are particularly important for communicating, interacting, and gaining information about their environment. While hearing parents have been shown to compensate intuitively for a deaf child's inability to perceive auditory cues (Koester, 1992, 1995), deaf parents may offer important insights into the use of other modalities to elicit and maintain a deaf infant's attention. Results of the study indicate a greater reliance among deaf mothers on visual strategies to regain infant attention, and a greater emphasis on vocalizations by hearing mothers, regardless of infant hearing status.
