Videotaped observations of the free-play interaction of mothers and (1) 12 physically handicapped, (2) 14 premature, and (3) 9 healthy 2-year-olds were evaluated. Results support clinical reports of maternal withdrawal from disabled young children. (Author/RH)

Examined relationships between early vocabulary composition, early language use, and properties of mothers' child-directed speech at 10 words. Found that, when the effects of the child on the mother at 10 words was controlled, there was a negative correlation between mothers' production of speech illustrating word boundaries and the percentage of…

Test-retest reliability of the Q-Sort Inventory of Parenting Behaviors was obtained with a sample of 30 mothers of 3-year-olds. The within-subject correlation, with 2 weeks between test administrations, for sorting the test statements was 0.72. Reliable differences among the respondents were responsible for 35% of the variance. (SLD)

Effects of enacted maternal withdrawal and depression were observed in a sample of 18- to 36-month-old children during counterbalanced episodes of simulated depression and normal affect. Found that when mothers enacted withdrawal and depressed affect, toddlers physically withdrew from them, made more negative physical bids for attention, and…

This study shows that the noun bias in early vocabularies rests only in part on the acquisition of object names. An analysis of vocabulary composition from 45 children at I;8 indicates that more nouns are acquired than all other word classes but that only about half of the nouns acquired are the names of basic level object classes (BLOCs).

Assessed parent-child interaction in 2-parent families with 12- and 18-month-old infants through questionnaires, interviews, family observations, and the Ainsworth Strange Situation procedure. Found no effect of family stress and marital adjustment on infants' attachment classification. Parents of 12 month olds reported greater marital adjustment…

This study documented communication behaviors of 18 hearing mothers and their infants with hearing loss, at 12 and 18 months old, and compared these behaviors with those of 18 mothers and infants without hearing loss. Both groups were similar in quantity of gestural and vocal expressive prelinguistic communication behaviors but not in formal…

Examined patterns of differential parental treatment, child outcomes, and family functioning with 60 families with toddler and preschool siblings. Found that congruence in mothers' and fathers' reports of differential treatment was most frequent. Reports of differential enjoyment were related to differential favoritism, whereas reports of…

Evaluated changes in mothers' interactive behaviors with infants from 6 to 40 months who were medically high risk, medically low risk, very low birthweight preterm, or full-term. Found that variations in mothers' responses to children's changing capabilities predicted rates of change in children's social skills. (Author/KB)

This study examined whether maternal responsivity would predict the extent to which prelinguistic milieu teaching (PMT) facilitated generalized intentional communication better than a contrast small-group treatment with 58 children (ages 17 to 36 months) with developmental disabilities. If mothers were relatively responsive before treatment, PMT…

Fifty-eight prelinguistic children with developmental disabilities and their mothers participated in an experimental test of whether intentional communication elicits maternal responses purported to facilitate language development. Results indicated that treatment effects on maternal responses varied by pre-treatment maternal education level and…

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…

Examined European- and Hispanic-American mothers' multimodal communication to their 5- to 30-month-olds while they taught the children target words by using distinct objects during play. Found that mothers used target words more often than nontarget words in synchrony with object motion and sometimes touch, and tailored communication to infants'…

This study explored effects of training six mothers to use focused stimulation to teach specific target words to their toddlers with Down syndrome. Following treatment, trained mothers used the focused stimulation technique more often than mothers in the control group. Concomitantly, their children used target words more often, as reported by…

Examined longitudinal associations between infant-parent attachment and parent/toddler behavior during storybook interaction. Found that infants with insecure-resistant attachment with mothers were less enthusiastic and focused during storybook interaction at 24 months. Mothers of insecure-resistant infants were less warm/supportive, and less…
