In this article, we provide an overview of the last twenty years of research on Indigenous sign languages, deaf community sign languages, co-speech gesture, and multimodal communication in the Australian context. From a global perspective, research on sign languages and on the gestures that normally accompany speech has been used as the basis for…

I review the classic literature in generative grammar and Marr's three-level program for cognitive science to defend the Evaluation Metric as a psychological theory of language learning. Focusing on well-established facts of language variation, change, and use, I argue that optimal statistical principles embodied in Bayesian inference models are…

Challenges the position of Clark (1988) that no two forms in a language can mean the same thing. An alternative is offered that draws on the drive towards the adult system, development of nonlinguistic concepts, acquisition of language in context, and use of a cooperative principle in conversational exchanges.

Argues against Youssef's treatise which pointed out some difficulties in attempting to test Bickerton's language bioprogram hypothesis (LBH), contending that the treatise seriously misunderstood certain key concepts of the LBH and dismissed with questionable reasoning some important findings which supported the state/process distinction as a…

A discussion of the role of linguistic theory in explaining language acquisition proposes that theory draws too narrow a picture of language to adequately account for the developmental phenomena of acquisition. While recognizing the importance of descriptive linguistic research, a new approach cautions against embracing description to the…

An overview of the babbling stage in child language acquisition, which occurs normally at age six months to one year, looks at research on this period. The babbling stage is preceded by arbitrary infant vocalization and is succeeded by production of simple but recognizable words. Babbling represents a period of increasing pattern and articulatory…

Presents examples of how children acquire language through the principles-and-parameters model, a highly modular system in which different theories interact so that only permissible sequences arise, and highlights research on Spanish syntax and semantics. (136 references) (CB)

This brief overview of child language acquisition begins with a discussion of the affective and cognitive dimensions of the transition period from babbling to speech. Three theories of language acquisition--reinforcement theory, social learning theory, and "innate mechanism" theory--are reviewed. Several theories of the function of language,…

Reviews evidence supporting the Contrastive Hypothesis, revealing little support for the hypothesis that young children automatically assume that every two words in their lexicons contrast. Theoretical problems with the positions that children assign words to semantic fields as they are acquiring them and that innovations are used to fill lexical…

Argues that current attempts to show that forward directionality effects can also be induced in Japanese acquisition do not succeed in supporting the forward directionality preference of anaphora. (57 references) (Author/CB)

Applies a categorical framework for relating compounds and metaphors to a discussion of the aspects of children's development of preferred and metaphoric compounds. Results indicate that preferred compounds serve the function of being conceptually precise, while preferred metaphors serve "suggestive" functions. (Author/CB)

Discusses the concepts of linguistic awareness and metalinguistic consciousness and their development in individuals, and shows how making a distinction between the two concepts can be useful to linguists, particularly in the areas of first and second language learning. (CFM)

Attempts to demonstrate that specifically language-impaired (SLI) children can be viewed as normal learners faced with systematically altered input. By assuming SLI children are limited in their ability to perceive and hypothesize grammatical morphemes that are low in phonetic substance, many features of SLI children's language can be explained by…

Suggests that Goad & Ingram's (1987) argument in favor of a cognitive model of phonological development failed to recognize the uniqueness of each individual's neural and vocal structures, ignored documented variability in the phonetic patterns of prelexical infants, and inexplicably assumed that inter-child variability implied the operation of…

Explores the process of language acquisition, including such aspects as pre-language, speaking and signing, and cultural influences, focusing on the resulting language acquisition differences and needs of children whose language ability and medium do not correspond with those of their family. (CB)
