ECOLOGY OF LANGUAGE ACQUISITION. Jonathan Leather and Jet van Dam (Eds.). Dordrecht: Kluwer, 2003. Pp xiv + 225. $88.00 cloth.

This volume contains 11 papers on various aspects of language acquisition both in first language (L1) and second language (L2) from an ecological perspective. This approach departs from generative grammar by rejecting both its theoretical and methodological axioms. It first questions the generative assumption that language is a mental state determined by human biology and experience. In its stead, proponents of the ecological view treat language as an entity inseparable from the speakers and their social network (Leather & van Dam, chapter 1). Methodologically, they dismiss generative grammar's essential tenet that competence should be investigated independently of performance; along with this, they also reject idealization in the study of language and language acquisition. Leather and van Dam also presume a priori the nonexistence of context-free meanings (cf. Higginbotham, 1988). As for language acquisition, they claim that the notion of primary linguistic data is too narrow; rather, data in other forms such as gestures and deictic motion are equally relevant in language acquisition. Although both the generative and ecological approaches emphasize individual language learners, for the former, language development constitutes the normal human biology, triggered by sensory input (Chomsky, 1995), whereas for the latter, it results from the interaction of the individuals and their cultural environment.
