This review article presents evidence for the claim that frequency effects are pervasive in children's first language acquisition, and hence constitute a phenomenon that any successful account must explain. The article is organized around four key domains of research: children's acquisition of single words, inflectional morphology, simple…

Investigates an aspect of child phonology and consonant harmony, and inquires whether representational or processing deficits are responsible for its occurrence. (36 references) (GLR)

Demonstrates the important need for language researchers to fill in the considerable theory data gap regarding the primary acquisition of Spanish by pointing out that theory development could be distorted if cross-linguistic comparisons of acquisition evidence draw on a faulty, incomplete data base.

Thirteen papers in this book illustrate MacWhinney and Bates's Competition Model (CM), with a focus on cross-linguistic processing. Studies in this volume show that (1) the CM is useful in predicting certain gross cross-linguistic differences of comprehension, particularly in relation to actor assignment and (2) children's processing strategies…

Provides an experimental validation of Landau and Gleitman's (1985) syntactic bootstrapping procedure on how children may use syntactic information to learn new verbs. The children's choice of the correct referent for a given verb versus a nonsense verb in two syntactic structures is explained. (37 references) (GLR)

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…

Research on child language acquisition should distinguish between different possible causes of variation and not just attribute variation to individual variation. An alternative analysis using a different methodology can show that children's patterns of acquisition are actually relatively similar. (Author/CB)

Studies analyzing children's response time to detect word targets revealed that six-year-olds and younger children generally did not show the response time advantage for accented target words which adult listeners show, providing support for the argument that the processing advantage for accented words reflects the semantic role of accent as an…
