In a brief article published some years ago (Foster-Cohen 1993), I suggested that fruitful collaboration between the fields of first and second language acquisition was underexploited. I also suggested that second language researchers were, in general, better at keeping themselves informed of developments in first language studies than first language researchers were at paying attention to second language issues. I think it fair to say that there are some signs this is changing. One is the now established existence of the journal Language Acquisition (Lawrence Erlbaum Associates), started in 1990, which publishes work in both first and second language acquisition with a view to understanding the nature of language acquisition in general. Its preference for papers that address issues in formal linguistic theory complements well Applied Psycholinguistics (Cambridge University Press), which has always published material relevant to both fields, but which also goes well beyond acquisition issues in its brief. A second factor seems to be a gentle but insistent re-examination of issues in bilingualism and a growing awareness that bilingual studies, second language studies, and first language studies overlap in important ways in the study of the bilingual individual. One key indicator of this shift is the appearance of a new journal Bilingualism: Language and Cognition (Cambridge University Press).
