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…

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)

The research reported is part of an investigation into the acquisition of grammar, using nonlinguistic information from situational and behavioral context to analyze the development of linguistic expression. Three children were seen for approximately 8 hours, every 6 weeks, in their homes, from the age of 19 months--soon after the earliest…

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…
