Defining and observing social signals in deaf and hearing infants.

Infant gaze, gestures, and affective expression have become generally accepted as indicators of the infant's efforts to initiate or resume interaction with a partner, particularly during moments when the mother may be temporarily unresponsive as shown experimentally in the maternal "Still-Face" situation. Previous studies comparing deaf and hearing infants using this paradigm have revealed diminished signalling by deaf infants with hearing mothers, when signals were defined by the typical indices mentioned above. This study compares results from both a microanalytic coding system (used with 59 dyads) and a more global examination of efforts by 20 deaf and 20 hearing infants to re-engage their deaf or hearing mothers. Emphasis is on the kinds of infant signals that often remain undocumented due to methodological constraints, but that may be recognized by the mother and elicit a delayed response from her when she is able to resume her normal interactive patterns. Results indicate that when these additional "signal" behaviors are considered (such as repetitive hand, arm, or foot movements, or behaviors previously prohibited by the mother), there are few overall differences in eliciting efforts by deaf and hearing infants.

Communicative interactions of deaf and hearing children in a day care center. An exploratory study.

Interactions were observed in a day care center serving deaf and hearing children. Observations focused on eight children (two deaf with deaf parents, two deaf with hearing parents, two hearing with deaf parents and two hearing with hearing parents) between 2 and 3 years of age. Center classes included deaf and hearing teachers and all children were encouraged to sign. Deaf and hearing children alike frequently interacted with other children and teachers whose hearing status differed from their own. However, each group showed a stronger tendency to initiate communication with same hearing status peers. Hearing children displayed the ability to modify their communications modes to match the hearing status of their intended communication partner. Language ability, not hearing status, was associated with the frequency of communication experienced by each child.

Social support, motivation, language, and interaction. A longitudinal study of mothers and deaf infants.

This project examined the effect of early cognitive, social, and communicative experiences on later social and language development in deaf infants with hearing mothers. Interactions between mothers and deaf infants were found to be positively influenced by social support provided to mothers in the early months of the infants' lives, mothers' visual and tactile responsiveness when their infants were 9 months of age, infants' ability to cope with interactive stress at 9 months of age, and fewer attempts by infants to engage with the social environment during the mastery motivation assessment at 9 months of age. Neither mother-infant affective matching nor maternal visual-tactile responsiveness correlated with the deaf infants' language level.

Intuitive parenting as a model for understanding parent-infant interactions when one partner is deaf.

This paper reviews the concept of intuitive parenting, with particular focus on its applicability to parent-infant dyads in which the parent or child is deaf. Although the conceptual model discussed in this paper was developed primarily from observations of hearing dyads, it has the potential to contribute to our understanding of early adaptive processes in other populations as well. Examples of nonconscious or intuitive parental behaviors are presented in terms of the ways they help infants adapt to the postnatal environment and in the later transition from preverbal to verbal stages of development. In addition, implications are drawn for difficulties in parent-infant interactions that may occur as a result of deafness in the parent or child.

Preference for complexity in the auditory and visual modes.

The contribution of sex and age was determined in comparisons of complexity preference in the auditory and visual modes. Six tonal passages and 22 random polygons of varying complexity constituted the auditory and visual stimuli, respectively. Preferences for complexity were elicited from 30 M and 30 F Ss, all of similar socio-economic status, in each of the age groups 5 and 17 yrs. Preference for complexity was not correlated across auditory and visual modes for any age or sex group. It was interesting, however, that although for 5-yr-old boys there was anon-significant inverse relationship between modes, and for 17-yr-old youths there was a non-significant direct relationship, the difference between these two correlations was significant. There was a significant (p less than .001) increase in visual complexity preference with age, although no such effect was found for auditory complexity; preference in the auditory mode remained at a moderate level for all groups.
