Maternal wait time after open- and closed-ended questions with eight Down syndrome (DS) and eight language-age (LA) matched peers was investigated. Mothers provided a longer mean wait time for LA children (2.5 seconds) than for DS children (1.8 seconds). These wait times matched well with children's usual response times. No differences for…

Reports development as compared to age-related changes in maternal task instruction to children in their second year. Interactions of 12 mother-infant pairs involved with simple tasks were video-recorded bimonthly between the infants' 14th and 22nd month. Comparison revealed the superiority of the development-centered model of adaptation of…

Families were compared at one, three, and nine months to examine the effects of active or passive exposure to the Brazelton Neonatal Behavior Assessment. Either the mother or both parents were the target of the intervention. Assessments of interaction behavior between parents and infants revealed no effects of the experimental intervention.…

The study with 18 children with Down Syndrome (DS), their mothers, and a control group replicated previous findings that mothers of DS children are more directive and identified qualitative differences in types of directives (e.g., mothers of DS children were more likely to request actions) suggesting differences in maternal interactive…

Comparison of communication between hearing mothers and their deaf or hearing children (n=80) at child-ages 22 months and 3 years found most of the differences in communication by mothers of deaf and hearing children seemed attributable to the deaf children's linguistic delays. Results suggest that intervention efforts should focus on fostering…

Examines difficulties associated with the use of conversational features in the analysis of mother-infant vocalization episodes. Observations of six mother-infant dyads revealed difficulties involving (1) pooling of data; (2) the unit of analysis; and (3) selection of appropriate "expected" values for dyadic parameters used in tests of…

Evaluation of the verbal interactions, especially maternal directives, among three mothers and their young blind children indicated that counting single occurrences of directives ignores the possible adaptive role that directive sequences may have in conversational interactions with blind children.

Comparison of 18 mothers and their late-talking male toddlers with 18 mothers and their typically developing male toddlers found no significant differences in degree of synchrony between mothers and children, mothers' use of social cues, play synchrony, compliance, or overall communicativeness, although the late talkers made significantly fewer…

This study compared efforts of 20 deaf and 20 hearing infants to reengage their deaf or hearing mothers in a maternal "still-face" situation. When all kinds of infant signal behaviors were considered, few overall differences were found in eliciting efforts by deaf and hearing infants. (Author/DB)

Interactions between 25 mothers and their developmentally delayed children (ages 2-5) during 15 minutes of semi-structured free play were coded independently with a global rating scale and a behavior count coding scheme. Correlational analyses were performed around three central themes: (1) the nature of the relationship between maternal…

This longitudinal study looked at how communication developed in seven deaf infants (ages 6-18 months) with either deaf or hearing parents. The children were video- recorded in interactional settings with their parents in their home every second month. A parallel study was conducted with seven blind infants and three severely visually impaired…

Three matched groups--hearing mother-hearing child, hearing mother-deaf child, and deaf mother-deaf child--were videotaped. Hearing mothers of deaf children were less likely to adapt their interactional strategies to meet their children's communicative needs and achieve intersubjectivity than were the other mothers. Results support Lev S.…

This observational study examined 60 mothers' comments during play with their 4- to 8-month-old infants who had been either full-term, preterm well, or preterm sick. Mothers of sick preterm babies engaged in the most overall talking, mothers of full-term babies made the most negative remarks, and mothers of healthy preterm babies made the fewest…

A longitudinal study (with data collected at 54 and 83 months of age) was conducted of conversational control in 34 dyads of mothers and their children with severe and profound hearing losses. Results indicated that maternal control was negatively related to the children's developmental levels, and declines in control were not commensurate with…

This study of the pragmatic characteristics of conversations between mothers and their 30 preschool children with developmental delays found significant differences between naturally occurring and researcher-introduced semistructured situations in the proportions of conversational turns taken and the pragmatic functions of mothers' and children's…
