The purpose of this research was to show how the syntactic and semantic components of the tense-aspect system interact during the acquisition process. Our methodology involved: (1) identifying predicates, (2) finding the initial occurrence of their tense-aspect morphology, and (3) observing the emergence of contrasts. Six children learning Polish…

Childers and Tomasello (2001) found that training 2 1/2-year-olds on the English transitive construction greatly improves their performance on a post-test in which they must use novel verbs in that construction. In the current study, we replicated Childers and Tomasello's finding, but using a much lower frequency of transitive verbs and models in…

Two studies addressed the relative strengths of object kind bias and syntactic knowledge in 2-year-olds' inductions of word meaning. The study looked at children's interpretations of novel proper names for familiar and unfamiliar objects. In each study, 10 children were assigned to each of 2 conditions (familiar and unfamiliar) and shown 2 cats…

The nature of semantic roles and grammatical relations are explored from the perspective of Role and Reference Grammar (RRG). It is proposed that unraveling the relational aspects of grammar involves the recognition that semantic roles fall into two types, thematic relations and macroroles, and that grammatical relations are not universal and are…

A study investigated children's hypotheses about the meanings of novel verbs on the child's first exposure to the verb. The study focused on the properties (action, result, or instrument) ascribed to the verbs before any information was given about word meaning. Subjects were 3-year-olds, 5-year-olds, and adults. The stimuli were six sets of…

Three experiments with children between 5 and 7 years are described. It is shown that nominal predication of an unknown word by a superordinate term enables young children to make appropriate inferences concerning its attributes. The results are discussed in relation to semantic development and reasoning in the young child. (Author/RM)

The booklet discusses and reports on a study of elicited imitation as a vehicle for assessing the language-functioning level of echolalic autistic children. An historical overview is presented of the diagnosis of early infantile autism. The question of whether or not early infantile autism is a distinct syndrome is addressed. The theoretical and…

The author considers controversial psycholinguistic problems in the study of first and second language acquisition, raising such questions as whether all children learn language in the same way, and whether all languages are learned in the same way. Her observations, based partially on observing her own bilingual child, suggest that the cenematic…

Ludwig Wittgenstein's pragmatic conception of language, his theory on language learning, and his treatment of the function of language in the growth of the child are the focus of this book. Wiggenstein's study of language is compared with those made by linguists, psychologists, and sociologists, and accounts of language learning based on empirical…

Selected spontaneous errors of word choice made between the ages of two and five by two children whose language development had been followed longitudinally were analyzed for clues to semantic developmnet. (JMB)

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,…

Discusses the audio and video-recorded longitudinal data from six infants with varying degrees of vision. The findings indicate that there are basic differences in early language, which appear to reflect differences in cognitive development. (SL)

This case study of two Latvian children attempts to show how the parental terms for"mummy" and "daddy" in Latvian are acquired, paying particular attention to the changing relationship between the input and output forms during the acquisition process. (Author/RM)

Examines the influence of the situational environment on language use in the classroom. (RL)
