This dissertation articulates and defends a view about linguistic competence called 'variabilism'. According to variabilism, the epistemic demands of full linguistic competence vary in a particular way. More specifically, variabilism holds that different individual lexical application conditions (individually essential metaphysical ways of being…

This dissertation investigates the wide-ranging implications of a simple fact: language unfolds over time. Whether as cognitive symbols in our minds, or as their physical realization in the world, if linguistic computations are not made over transient and shifting information as it occurs, they cannot be made at all. This dissertation explores the…

Vulnerability of morphosyntactic production, including grammatical aspect, has been identified in at least some children with autism spectrum disorder (ASD) exposed to typologically different languages. However, Tovar et al. (2015) found strengths in comprehending grammatical aspect in English-exposed children with ASD, suggesting that the…

Metaphor development in conjunction with verbal intelligence and linguistic competence in middle childhood and at the transition to early adolescence was investigated. 298 individuals between seven and ten years (chronological age) who attended grades two-four (mental age) were tested for metaphor processing by the Metaphoric Triads Task, for…

Acquisition in general and first language acquisition in particular is a very complex and a multifaceted phenomenon. The way that children acquire a language in a very limited period is astonishing. Various approaches have been proposed so far to account for this extraordinary phenomenon. These approaches are indeed based on various philosophical…

In this paper we discuss a computational cognitive model of children's poor performance on pronoun interpretation (the so-called Delay of Principle B Effect, or DPBE). This cognitive model is based on a theoretical account that attributes the DPBE to children's inability as hearers to also take into account the speaker's perspective. The cognitive…

Studies have investigated and proposed different potential influences on children's initial mappings of object words to referents. Each proposal is a variant on the idea that children use one source of evidence about the structure of word meanings or of grammar to discover other forms of structure, and in doing so they "bootstrap" their…

This book contains a collection of current research in the development of speech perception and perceptual learning. The collection integrates research involving infants, young children, and adults, and explores systematically how adult perceptual abilities develop from early infant capabilities, focusing particularly on the nature of transitional…

Reviews research pertaining to metalinguistic awareness in young children; examines issues related to the direction of cause between metalinguistic abilities and reading, disparities in research methodology between studies, and commercial instruments perporting to measure metalinguistic knowledge; and offers implications for reading instruction…

A taxonomy developed for the study of the growth and development of written language from the perspective of social event was tested with a group of 68 children, aged three to six years. The subjects were presented with a wide variety of environmental print messages (road signs, toys, fast food signs, and household products) and were questioned…

Examines similarities between human evolution of language and the development of child's language, including the gradual building of sentence, the use of gestures, and the introduction of symbols. Discusses principles of human uniqueness, brain development, and the internal mechanisms for language stages, and offers conclusions similar to…

The ways in which preschoolers use the word "but" were studied. It was found that the eight preschoolers, who ranged in age from 3;9 to 5;5, were able to use "but" to express a number of different types of adversative relationships. "But" introduced clauses containing information that: (1) contrasted with shared knowledge about the usual state of…

Reports three experiments which examined preschool, first-grade, and third-grade children's understanding of metaphorical language. Subjects acted out short stories which ended in metaphorical sentences by using toys. Predictability of the story endings and the complexity of the metaphorical sentences are found to affect metaphor comprehension.…

Pragmatics, the use of language in context, has been investigated only recently in the language used by children who stutter (CWS). Historically, researchers compared the length and complexity of the syntactic constructions produced by these children with those of children who do not stutter (CWNS) and generally found the CWS to be relatively…

Sixteen children (aged 14 to 26 months), who were reported by their parents to overextend, were tested for overextension in both language production and comprehension. The children were first asked to name each of a series of pictures of inappropriate exemplars of the words they were reported to overextend. Those words that were overextended, a…
