Social deficits have been implicated in the language delays and deficits of children with autism (ASD); thus, the extent to which these children use language input in social contexts similarly to typically developing (TD) children is unknown. The current study investigated how caregiver input influenced the development of "wh"-question…

The relation of social and linguistic input measures to early vocabulary development was examined in 30 low-income African American mother-infant pairs. Observations were conducted when the child was 0 years, 1 month (0;1), 0;4, 0;8, 1;0, 1;6, and 2;0. Maternal input was coded for word types and tokens, contingent responsiveness, and…

Relationships between syntactic and semantic aspects of mothers' speech and infants' word acquisition was examined in 27 mother-infant dyads. Results indicated that the more the mother differentiated the complexity of her speech to child and adult, the earlier the child attained 20 words. The more the mother used adult-basic labels in her speech,…

Assesses the interrelations among the functional properties of maternal speech, the structural properties of maternal speech, and child language growth for a period of six months for 22 two-year-old children and their mothers. (HOD)

Longitudinal observation of 12 infants, including measures of child behavior and maternal language and child language, revealed that most subjects acquired a balanced distribution of object labels and social-centered words and phrases. (Author/CB)

Examined whether the characteristics in perception of speech sounds found in preverbal hearing infants might extend to the perception of signed language in infants with congenital deafness. Seventeen Japanese mother-infant dyads participated in the study. Found that infants with deafness showed greater attentional and affective responsiveness to…

This article hypothesizes that language repetition of young children (in the sense used by Kobashigawa and Snow) does not help language acquisition. The evidence comes from the results of a prior study in which no indication was found that mothers who repeat themselves a great deal have children who acquire language more quickly. However,…
