Evidentials are grammatical elements such as affixes and particles indicating the source of knowledge. We provide an overview of this grammatical category and consider three research domains to which developmental studies on evidentiality contribute: the acquisition of linguistic means to characterize knowledge, the conceptual understanding of…

Studies of copular forms are extremely relevant to issues in philosophy, psychology, and linguistics. Psychologists have recently argued that the most distinctive aspect of human language is its combinatorial nature (e.g., Gentner, 2003; Spelke, 2003). They argue that this linguistic component might be what separates human from animal cognition.…

Bilinguals must have a mechanism for controlling attention to their two language systems in order to achieve fluent performance in each language without intrusions from the other. This paper examines the evidence that the experience of controlling attention to two languages boosts the development of executive control processes in childhood for…

In a study using preschool and elementary school children, the children's judgments of whether brief stories described valid instances of a concept shifted in a manner consistent with the authors' hypothesis that meanings typically develop from representations in which characteristic features predominate to those in which defining features become…

Investigates in an experimental setting the claim that young children have some knowledge of the rules of correspondence between language and reality which are central to propositional logic. (EKN)

In 1986, while still at Harvard, I started teaching summer school at the Bread Loaf School of English, the graduate program in English of Middlebury College. Bread Loaf offers courses in literature, theater, and writing--here I fit in. I came to that job with a background in applied linguistics and cognitive development, but not in literature, and…

While almost all observers agree that young children, older children, and adults differ both in initial rate of acquisition and in the levels of ultimate attainment typically achieved, they continue to disagree over whether the observed patterns are a function of nurture or nature. Is it simply that older starters "do not" do as well because they…

Presents background to the descriptions and discussions of child language that are presented in this issue of the journal on the theme of developing pragmatic competence. This background information, referred to as "intuitive knowledge," serves as a framework for understanding children's development of pragmatic linguistic competence and…

Describes a computer program under development that is to be used as a tool for theory builders, teachers, and students in language learning. This is an interactive program and not only helps the learning of a language but also provides analysis on how language is learned. Questions if computers learn. (GG)

Discusses the role of language development in educational achievement and the implications of this role for curriculum development. Children's preschool knowledge of language and its development in early school years is discussed. How their language experiences in school might enhance their language development also is outlined. Highlighted are…

This paper considers psycholinguistic aspects of bilingualism from two perspectives: the psychology of the individual and social psychology. The linguistic development of children is described and research is presented that compares bilingual and monolingual children with respect to cognitive development. The emotional consequences of parents'…

Identifies five recurring themes in the literature on bilingualism: role of language policy or planning activities in educational reform; concern with nurturing the mother tongue and facilitating transfer of skills across languages; importing a model versus a "cycle of discovery"; practical problems that impede implementation of…

The last 25 years have witnessed an explosion of research at the intersection of typical language development and child language disorders. A pioneer in bringing these fields of study together is Robin S. Chapman, Emerita, University of Wisconsin. This contributed volume honors her with chapters written by former students and colleagues, who track…
