Many children learn language, in part, from the speech of non-native speakers who vary in their language proficiency. To investigate the influence of speaker proficiency on the quality of child-directed speech, 29 mothers who were native English speakers and 31 mothers who were native speakers of Spanish and who reported speaking English to their…

Background: In recent years many studies have shown that the use of cochlear implants (CIs) improves children's skills in processing the auditory signal and, consequently, the development of both language comprehension and production. Nevertheless, many authors have also reported that the development of language skills in children with CIs is…

Some research in child language suggests that semantically general verbs appear in grammatical structures earlier than semantically complex, specific ones. The present study examines whether this was the case in nouns, using imageability as a proxy measure of semantic generality. Longitudinal corpus data from 12 children from the Manchester corpus…

The MacArthur-Bates Communicative Development Inventory (short form) was adapted for Samoan and Tongan speakers in New Zealand. The adaptation process drew upon language samples from Samoan and Tongan parent-child dyads with 20- and 26-month-old children and adult informants. The resulting 100-word language inventories in Samoan and Tongan, plus a…

Acquisition of regular inflectional suffixes is an integral part of grammatical development in English and delayed acquisition of certain inflectional suffixes is a hallmark of language impairment. We investigate the relationship between input frequency and grammatical suffix acquisition, analyzing 217 transcripts of mother-child (ages 1 ; 11-6 ;…

The present study determined whether parenting style, defined by control strategies varying in power-assertion mediated the established relation between maternal language usage (grammar and semantics) and child language (grammar, semantics and pragmatics) during toddlerhood (n = 60). Based upon their use of control strategies mothers were…

The current study examines the syntactic and prosodic characteristics of the maternal speech to two infants between six and ten months. Consistent with previous work, we find infant-directed speech to be characterized by generally short utterances, isolated words and phrases, and large numbers of questions, but longer utterances are also found.…

Expands on study by Brown and Hanlon which showed that parents seemed more attuned to semantic value of their child's speech rather than grammatical form. However, this more recent study suggests that language learning environment presents subtle cues, distinguishing between well-formed and ill-formed sentences, evidenced by mothers' inclinations…

Investigated how prosodic cues in motherese assisted infants' language acquisition. Infants oriented longer to speech interrupted at clausal boundaries than to matched speech interrupted at within-clause locations. The prosodic qualities of motherese provided infants with cues to units of speech that corresponded to grammatical units of language.…

Describes a study of spontaneous speech from two young children and their mothers to examine how children learn some of the inflectional/syntactic possibilities for individual verbs. Multiple regression analyses were used. Maternal variety of use was a highly significant predictor of the children's use of the same verbs. (Author/SED)

Reports on a study investigating the relationship between children's linguistic environment and language acquisition. In particular, the study examined the effect of mothers' speech on subsequent child speech. (Author/AM)

Examined 1 hour of conversation between 12 mothers and their 23-month-old children. Children were more likely to imitate correct grammatical morphemes after mothers' corrective recasting of children's errors than after three types of maternal responses that did not correct an error but did model a morpheme.

A longitudinal study of the language development of children of adolescent mothers followed 20 adolescent and 20 older mothers from their children's birth through three years of age. This report is based on data collected from a subsample of 20 mothers. Mother-child interactions in feeding, teaching, and play at eight months and two years were…

A study tested the hypothesis that if, for the 2-year-old, the transitive/intransitive distinction functions to signal differences in the conceptualization of actions, the child's sentence production should show a relationship between sentence frame and (1) locus of change animacy and (2) the child's expectations concerning an action's outcome.…

This study investigated the use of generic noun phrases by preschool children and their mothers. Results indicate striking differences in the way generics and non-generics are distributed in the speech of both groups, suggesting generic noun phrases differ in their semantics and conceptual organization from non-generics and may reflect children's…
