The early development of vocalic and consonantal production in Mandarin-learning infants was studied at the transition from babbling to producing first words. Spontaneous vocalizations were recorded for 24 infants grouped by age: G1 (0 ; 7 to 1 ; 0) and G2 (1 ; 1 to 1 ; 6). Additionally, the infant-directed speech of 24 caregivers was recorded…

A child acquiring a language must learn to correctly match the phenomena of the realworld which he perceives with the lexical items and the segregates and perhaps some of the grammatical categories of the language to be learned. He must correlatively learn the organization in meaning of and among these last named elements, that is, the internal…

Based on a series of lectures given at the Summer Language Program, University of California at Santa Cruz, August 1972; translated from the English; special issue on "Changing Linguistics." (DD)

The present research investigated whether children's referential choices for verb arguments are motivated by pragmatic features of discourse referents across different developmental stages, not only for children learning null argument languages but also for those learning overt argument languages. In Study 1, the form (null, pronominal, or…

A discussion of the child's language acquisition including examples of syntactic development. This analysis is introduced by references to various language theories, particularly the generative and psycholinguistic theories, and to various systems of syntactic description. The examples given raise questions on the theoretic and ideological levels.…

This paper outlines a proposal to cover four very early stages for the acquisition of negation systems in natural languages. It emphasizes the formal linguistic devices as the major variables that determine the various language-specific developmental sequences. (CHK)

Outside the core grammar, the set of "peripheral" or marked properties of a language include exceptions or relaxations of the settings of core grammar and the idiosyncratic features of the language governed by particular lexical items. The core/peripheral distinction has direct implications for grammatical development in children. The…

Analysis of Sesotho-speaking children's spontaneous language showed that the acquisition of passives was closely linked to the fact that Sesotho subjects must be discourse topics. It is suggested that a detailed analysis of how passive constructions interact with other components of a given linguistic system is critical for developing coherent and…

The ability of children between the ages of two years and four years, eight months, to produce locative pre- or postpositions was investigated in English, Italian, Serbocroatian, and Turkish to discover universals of conceptual and communicative development. (Author/AM)

For the linguist interested in typology and language universals, this paper suggests the usefulness of a taxonomy of copula and copula-like constructions in the world's languages and the elaboration of hypotheses of synchronic variation and diachronic change in this part of language. For the linguist interested in child language development, the…

Examines the relationship between phonetic substitution patterns in child speech and sound change patterns in dialects of adult language, basing an explanation of these phenomena on acoustic data and language universals. (AM)

Compares the prosodic modifications in mothers' and fathers' speech to preverbal infants in American and British English, French, German, Japanese, and Italian. Speech samples were instrumentally analyzed to measure mean fundamental frequency, variability, utterance, duration, and pause duration. (67 references) (Author/CB)

Presents evidence for four major design features of serial organization of speech arising from comparison of babbling and early speech with patterns in ten languages. Maintains that no explanation for the design features is available from Universal Grammar; except for intercyclical consonant repetition development, perceptual-motor learning seems…

This work is an English translation of the author's classic "Kindersprache, Aphasie und allgemeine Lautgesetze," first published in 1941. It is considered the most representative and comprehensive of the author's phonological writings, dealing not only with phonological typology but related problems of language acquisition and phonemic regression…
