This dissertation presents a series of case studies concerned with whether the signal in a given set of measurements that we take in the course of linguistic inquiry reflects grammatical competence or performance factors. We know that performance and competence do not always covary, yet it is not uncommon to assume that measurements that we take…

Language is seen as a system for communicative purposes and as such it involves more than just a structural organization. Indeed this view of language considers different kinds of competence which make communication really meaningful: linguistic, sociolinguistic discourse, and strategic. Linguistic competence is what we usually regard as the basis…

Within child language acquisition research, there has been a fair amount of controversy regarding children's knowledge of the grammatical properties associated with verbal inflection (e.g., tense, agreement, and aspect). Some researchers have proposed that the child's early grammar is fundamentally different from the adult grammar, whereas others…

This study is an attempt to investigate the efficacy of using existing semantic relations categories for understanding how children comprehend the verb "with" + noun construction. (Author)

Evidence is offered to support the view that linguistic competence cannot in principle be divorced from linguistic performance in order to abstract universal properties of grammars, that rules of grammar inevitably incorporate perceptual strategies and constraints, and that grammaticality and acceptability are related to predictability. A theory…

Study offers some evidence which bears on the amount of influence of the environment upon linguistic capacity. (Author)

This article discusses an experiment designed to examine the relationship between the external explanations that learners give for their language behavior, and actual language performance. The subjects who were native and non-native speakers of English were tested on their use of definite articles. (CFM)

This paper is a response to Lavandera's question regarding the limits of the study of language variation. Sociolinguistics is characterized by its desire to limit representational meaning much more narrowly than formal linguistics. In addition while formal linguistics views language as species-specific and designed to accomodate logical…

Expands on study by Brown and Hanlon which showed that parents seemed more attuned to semantic value of their child's speech rather than grammatical form. However, this more recent study suggests that language learning environment presents subtle cues, distinguishing between well-formed and ill-formed sentences, evidenced by mothers' inclinations…

This article outlines a model of the two basic components of a text, namely, the system of formal linguistic rules, and the realization of these rules into concrete discourse, by means of particular transformations. (Text is in French.) (CLK)

Analysis of two studies (interpreted in terms of the distinction between language acquisition and language learning) showed that subjects tended to cluster the -s's on a few verbs rather than randomly, suggesting that the morpheme may be acquired not in isolation but attached to particular verbs.

This assumption that non-standard speakers are limited in their linguistic ability is examined based on a larger study investigating the speech of working-class adolescents in Sydney, Australia's inner-city areas. Speech samples of four children are presented. An examination of verbal structures reveals that there is a predominance of simple…
