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…

In six analyses using the Child Language Data Exchange System known as CHILDES, we explored whether and how parents and their 1.5- to 5-year-old children talk about writing. Parent speech might include information about the similarity between print and speech and about the difference between writing and drawing. Parents could convey similarity…

This book concerns a neglected aspect of the education of bilingual children, namely, their potential desire and ability to learn to read before age 5. The basis of the study is considered in the chapter on children as early learners, which provides accounts of children being taught to read from the age of 6 months to 4 years. The next part of the…

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)

The types of gesture+speech combinations children produce during the early stages of language development change over time. This change, in turn, predicts the onset of two-word speech and thus might reflect a cognitive transition that the child is undergoing. An alternative, however, is that the change merely reflects changes in the types of…

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…

A study investigated the extent to which the nature of verb input accounts for the order in which children acquire verbs. Subjects were 57 mothers and their Stage I children. Results suggest that the effect of syntactic diversity in input supports the "syntactic bootstrapping" account of how children use structural information to learn new verbs'…

The crib talk reported here of a 2;2-2;4-year-old boy replicates the phenomenon of crib talk reported in previous studies by other investigators. This study adds a corpus of mother-child interaction (MCI) and tests one aspect of the hypothesis that crib talk may enhance production of linguistic forms at a later date. Transcripts of monologues were…

The order in which wh-questions are acquired in the production and comprehension of two Korean one-year-olds is analyzed and compared. Consistencies in acquisition order are to be based on universals of cognitive development, while discrepancies in acquisition order were attributed to differences in interactive styles across caregivers and…

A study examined patterns of development in spoken interaction and types of causal thought that might reflect the human capacity to displace, that is, to shift reference from the present moment to another moment in time. Participants were four infants and their parents, who came to a laboratory for one-half hour every 2 weeks from the child's…

Literature on the sighted child suggests that blind children might be delayed in language acquisition and/or restricted in the semantic content of their utterances and in the communicative intentions they express. This study questions the use of guidelines appropriate for monitoring sighted children in the study of language development in blind…

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,…

A discussion of word acquisition rates and strategies is based upon a 6-month case study of an Estonian-speaking child who gradually and systematically relaxed phonotactic constraints to allow greater complexity in word production. In addition to the cognitive tools of assimilation and accomodation as described by Piaget, the child used a further…

Maternal infant-directed speech in Mandarin Chinese and Turkish (two mother-child dyads each) was examined to see if cues exist in input that might assist infants' assignments of words to lexical and functional item categories. Results show that sets of distributional, phonological, and acoustic cues distinguishing lexical and functional items are…
