Two claims about early stages of language development--that of a limitation on length of utterance and that of reduction rules which delete major constituents from simple sentences--are questioned. Supporting arguments are reviewed, and alternative explanations offered. (RM)

The discussion throughout this paper is devoted to answering the question: What is the nature of our knowledge of language and what theoretical assumptions does the answer entail for linguistic description? Discussed are--(1) what it means to know a language, (2) the distinction between linguistic competence and performance, (3) justification of…

This paper, based on Rosenbaum's (1967) grammar of adult English, attempts to apply ideas of deep structure and transformations to child grammar. The main rules predicated include phrase structure rules, segment structure rules, contextual features, and transformational rules. In this approach, the role of transformations is to segment and place…

Research presented in this paper on the character of infant-directed speech and the nature of infant speech perception abilities from 6 to 12 months suggests that prosody contributes significantly to early analyses of child languages and assists infants in developing root processes of parsing.

Goodluck and Solan (EJ 205 641) presented alternative formulations about why errors predicted by basic operations fail to occur and suggested a refined hypothesis. Each aspect of their argument is addressed, and it is concluded that descriptive power, methodology and principles for restricting error predictions favor our original analysis. (RD)

Presents two analyses of deviant phonological systems. The one based on production evidence alone accounts for (1) differences in surface behavior of a set of phonetic segments with three possible phoneme sources, and (2) obstruent clusters across morpheme boundaries. The "substitution analysis" identifies the child's underlying representations…

The development of production and comprehension by one two-year-old girl of three Japanese constructions (passives, causatives, and "te moraw"), which have similar surface configurations "NP ga NP ni V ("rare"/ "sase"/ "te moraw") TENSE," is investigated through elicited imitations and responses to the investigator's questions about the content of…

This article provides a discussion of current topics in psycholinguistics and of the current research on these problems. The author discusses current thought on the biological foundations of language and the problem of universals. If human language is a species-particular achievement contingent upon a biological endowment, there should be certain…
