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…

Three experiments on the comprehension and acquisition of temporal terms are described. Methodological innovations were applied to control for possible methodological effects on children's performance. Each experiment involved 24 children aged 3 to 5. In the first experiment, subjects manipulated toys in response to instructions containing the…

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)

Investigates whether inflectional morphology is rule-based or whether the assumption of pattern association is more adequate to account for the facts, arguing for the latter based on analysis of acquisitional data. Review of earlier literature on the subject examines experiments with German- and English-speaking children and supports the schema…

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…

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…

A study was undertaken to determine how much knowledge children have of grammatical systems before they evidence the systems in their spontaneous speech in a productive way. A child aged about two and a half years was examined over several months through elicited imitation causing him to repeat a model sentence immediately after the researcher.…

The purpose of this study was to investigate the linguistic differences in the spontaneous speech of language-deviant children in two very different situations. Spontaneous speech samples of eleven five-year-old language-deviant children were obtained from: (1) the traditional adult-child therapy situation using appropriate stimulus materials; and…

If the question of what it is that is innate is simply left as some kind of human learning potential, this position, representative of the nativist philosophy, does not differ radically from that of behaviorists. The latter position holds that a human being starts out with a mind which is basically empty and receptive to, subject to, and the…

Three empirical studies were conducted to investigate the hypothesis that the "easy to see" construction (such as in the sentence "children are hard to understand") is acquired at a younger age than the 7-9 year range reported by previous studies (Cambon and Sinclair, 1974; Chomsky, 1969; 1972; Cromer, 1970; Kessel, 1970).…

The use of locative prepositions in the spontaneous speech of 30 Hebrew speaking children two to three years old was studied. The rank order of locative prepositions is determined according to the correct use in obligatory contexts, and tentative conclusions are drawn concerning the order of acquisition of these terms in Hebrew. An attempt is made…

The general goals of this study of Luo children in Kenya were (1) to provide a description of the acquisition of language in terms of categories acquired within the age range of 12-35 months; (2) to account for their linguistic competence in the generation of their language; and (3) to illustrate how social settings alter the linguistic…

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…

Sixty-five grade 5-6 children were tested on a verbal recall task involving material of varying semantic and syntactic content. There was no difference between best and poorest readers in their performance on random lists of words, but there were clear differences on meaningful sentences and on syntactically well-formed but semantically anomalous…
