Learnability theory involves the construction of formal mathematical proofs whose goal is to demonstrate how the child can successfully induce a mature grammar. An empirically adequate learnability proof constitutes a detailed hypothesis concerning the boundary conditions within which acquisition proceeds and can provide a general framework for…

Reports on a longitudinal study of the acquisition of the voicing contrast in American English word-initial stop consonants as measured by voice-onset time. The rate and nature of the developmental process are discussed in relation to two competing models of phonological acquisition and two hypotheses regarding the skills being learned. (Author/AM)

The purpose of this study was to determine what effect exposure to linguistic input pertinent to kinship terms and kinship relations has on the acquisition of the meaning of such terms. The subjects were 84 German children living in families, and 84 orphans. (Author/CFM)

Presents the goals of the Plunkett and Marchman (PM) connectionist model of the acquisition of verb morphology, and responds to related criticisms. Claims that small vocabulary size allows young children to correctly produce both regular and irregular past tense forms, and that non-linearities in vocabulary growth are a contributing factor to the…

Provides a look at primary grade children's abilities, inabilities, and requirements to use phonics as a beginning reading strategy and suggests a model that facilitates children's application of phonics while reading. (FL)

In response to earlier studies by Thompson and Chapman (1977) and Clark and Clark (1977), 16 middle-class and upper-class White children between 1.2 and 2.2 were tested for overextension in production and comprehension. (AM)

Replies to McLaughlin's (l978) critique of the Krashen (1975, 1977) Monitor Model of language learning, presenting rebuttals to major attacks, followed by a discussion of minor issues. (AM)

Research on the grammatical cues that guide comprehension of a language and that children are most sensitive to, particularly in Hebrew, is reviewed as an introduction to the first phase of a study conducted with 20 native Hebrew-speaking children aged 4 to 9 in southern California and a group of adults to provide comparative data. The study…

Presents a model that predicts writing growth in children as a logical outcome of language acquisition. Provides a list of the kinds of language learning underway in the elementary school years and suggests that teachers may use this list to anticipate where and how such learning will influence the writing processes of children. (FL)

This paper examines whether language development can be understood epigenetically in the same manner and based on the same principles with which Piaget has analyzed intellectual-cognitive development generally. The study is subdivided into four parts: (1) some principles in Piaget's system (the epigenetic principle, the genetic circle, and the…

This paper proposes a broad outline of a variable model of language development and explores several particulars of such a model in the language behavior of four two-year-old children. The process by which information about language is progressively transformed and integrated rather than merely being added together can be seen in the shifting…
