The validity of mean length of utterance (MLU) and a measure of syntactic complexity were tested against the language assessment, remediation, and screening procedure on spontaneous speech samples from 87 children, concluding that MLU is a valid measure of clausal complexity up to 4:5 and that the measure of syntactic complexity is more valid at…

Provides a contemporary Government-and-Binding reinterpretation and evaluation of Klima and Bellugi's 1966 work on the acquisition of interrogatives. It is argued that wh-questions in Child English involve a wh-pronoun positioned in the head complementizer position within the Complementizer Phrase (CP) and that children learn that wh-questions…

Investigated the first verbs to participate in verb-object and subject-verb-object combinations and the temporal parameters of the spread of these combinations over different verbs, observing longitudinally young children acquiring English and Hebrew. Results indicated that the more verbs children already knew to combine in a certain pattern, the…

The authors investigated the role of syntax in verb learning in Mandarin Chinese, which allows pervasive ellipsis of noun arguments. Two questions were investigated using the Beijing corpus on CHILDES: (a) Does the input to young children manifest syntactic-semantic correspondences as needed for acquiring verb meanings? (b) Are verbs presented in…

This study investigated the nature and extent of differences in young children's talk when they interact with mothers and peers. Sixteen girls between 2.5 and 3.5 years of age played twice with their mothers and twice with a peer. Play sessions were videotaped and coded according to measures of quantity and quality of talk. Results of measures of…

A study investigating the acquisition of empty categories (ECs) in Sinhala, a language of the Indo-Aryan family spoken in Sri Lanka, is reported in part. The results examined here concern ECs occurring in a subset of adverbial clause types differing with regard to the kinds of null subjects they permit, including those obligatorily coindexed,…

Dialogues of sets of socially similar twins are studied. The opinion that twins have slower syntactic development than non-twins is seriously questioned. Dialogues with twins saying the same utterance together, correcting each other, quarreling, playing verbal games, etc. are analyzed in their deep structure. (SCC)

Through discussion and illustrative events, an evolving segment of communication is described during the course of transition of one child's total communication system from the sensorimotor or gestural level at 12 months into the level of use of the adult words "more" and "mine," and associated utterances, at 24 months. (Author/RM)

A phonological and syntactic study of a small important group of nonarbitrary terms in Pomo baby talk that are concerned with elemental body needs. A progression is shown from sound images closely associated with the action state or object denoted to the phonological patterns of adult languages. (SCC)

This article discusses the relationship between the linguistic description of language and the speaker's acquisition and use of language, with specific reference to the role of paradigmatic and syntagmatic relationships in the acquisition of definition as a linguistic behavior. (Text is in French.) (AM)

Kindergarten-aged children's use of parallel constructions in their peer storytelling, while not common, reflect children's interest in the organizational principle of theme and variation. Semantic and syntactic parallelism represent two of many ways in which some youngsters employ theme and variation in their storytelling. The constructions give…

In a study extending and refining Carol Chomsky's research, 48 Arabic speaking children aged six, eight, and ten were tested for their comprehension of imperatives using the complement-requiring verbs Ask, Tell, and Promise. Clear support for children's overgeneralization of the minimal distance principle was found only with Promise constructions.…

Two groups of preschoolers and one of young grade-schoolers were tested for their comprehension of presuppositions and negation in complex syntax. Four types of sentences were presented: affirmative and negative versions of sentences with factive main predicates (which presuppose the truth of the proposition of the complement clause) and with…

Children's language acquisition is viewed by developmental psycholinguists as a process of change in the organization of language processing operations. Normal children seem to acquire their native language by this process, rather than by eliminating specific mistakes. Preschool language develops in stages, and knowledge of where syntactic change…

The author calls attention to a basic split between perception and cognition that psychologists or linguists tend to make either explicitly or implicitly. There is some psychological evidence to substantiate, at least for higher developmental levels, the functional importance of this split. The chief problems for psycholinguistics which arise out…
