Stoel-Gammon (this issue) highlights the close and symbiotic association that exists between the lexical and phonological domains in early linguistic development. Her comprehensive review considers two bodies of literature: (1) child-centred studies; and (2) studies based on adult psycholinguistic research. Within the child-centred studies, both…

This paper argues for broader consideration of children's language production systems and, in that context, describes research on children's planning of syntactic structures. The research presented here measures non-fluency patterns in elicited utterances of varied syntactic type. We describe and interpret several regularities in these patterns…

The present study investigates flexibility of verb use in the early stages of English multiword development, and its relationship with patterns attested in the input. The data is taken from a case study of a monolingual English-speaking boy aged 2; 5-2; 9 and his mother while engaged in daily activities in the home. Data were coded according to…

Parents' use of conventional versus unconventional labels with their two- (n=12), three- (n=12) and four-year-old children (n=12) was assessed as they talked about objects that were either known or unknown to them. For known objects, parents provided typical conventional labels casually during the conversation. For unknown objects, parents were…

This study examined relationships between prelinguistic variables from the MacArthur-Bates CDI and the development of language comprehension and production in children with autism. Forty-four children were assessed at baseline and 6, 12, 24, 33 and 53 months later. Growth Curve Modeling was used to examine the extent to which three composite CDI…

We investigate how Tamil- and Dutch-speaking adults and four- to five-year-old children use caused posture verbs ("lay/stand a bottle on a table") to label placement events in which objects are oriented vertically or horizontally. Tamil caused posture verbs consist of morphemes that individually label the causal and result subevents ("nikka…

This study explores the form of representational gestures produced by forty-five hearing children (age range 2 ; 0-3 ; 1) asked to label pictures in words. Five pictures depicting objects and five pictures depicting actions which elicited more representational gestures were chosen for more detailed analysis. The range of gestures produced for each…

The present study investigates children's bias when interpreting novel noun-noun compounds (e.g. "kig donka") that refer to combinations of novel objects (kig and donka). More specifically, it investigates children's understanding of modifier-head relations of the compounds and their preference for HAS or LOCATED relations (e.g. a donka that HAS a…

This study explores different frequency effects on children's interpretations of novel noun-noun compounds (e.g. "egg bag" as "bag FOR eggs"). We investigated whether four- to five-year-olds and adults use their knowledge of related compounds and their modifier-head relations (e.g. "sandwich bag (FOR)" or "egg white (PART-OF)") when explaining the…

We used a syntactic priming paradigm to show priming effects for active and passive forms in monolingual Spanish-speaking four- and five-year-olds. In a baseline experiment, we examined children's use of the "fue"-passive form and found it was virtually non-existent in their speech, although they produced important elements of the form. Children…

Parent report has proven a valid and cost-effective means of evaluating early child language. Norming datasets for these instruments, which provide the basis for standardized comparisons of individual children to a population, can also be used to derive norms for the acquisition of individual words in production and comprehension and also early…

Children find object relative clauses difficult. They show poor comprehension that lags behind production into their fifth year. This finding has shaped models of relative clause acquisition, with appeals to processing heuristics or syntactic preferences to explain why object relatives are more difficult than subject relatives. Two studies here…

The study examines strategies multilingual children use to interpret grammatical relations, focusing on their two primary languages, Lajamanu Warlpiri and Light Warlpiri. Both languages use mixed systems for indicating grammatical relations. In both languages ergative-absolutive case-marking indicates core arguments, but to different extents in…

Children who require augmentative and alternative communication (AAC) systems while they are in the process of acquiring language face unique challenges because they use graphic symbols for communication. In contrast to the situation of typically developing children, they use different modalities for comprehension (auditory) and expression…

Thai has imperfective aspectual morphemes that are not obligatory in usage, whereas English has obligatory grammaticized imperfective aspectual marking on the verb. Furthermore, Thai has verb final deictic-path verbs that form a closed class set. The current study investigated if obligatoriness of these grammatical categories in Thai and English…
