Productivity, Proceduralization and Specific Language Impairment Commentary on Hsu and Bishop

摘要

In the 1990s, many researchers tried to explain specific language impairment (SLI) by appealing to an innately specified 'language module,' which was assumed to be impaired in affected individuals. Over the years, language researchers have be-come increasingly dissatisfied with this explanation, and a number of alternative ac-counts have been put forward which attempt to explain the language difficulties in second language acquisition as a consequence of an underlying processing or learn-ing deficit. Hsu and Bishop's [this issue] contribution is part of this research tradi-tion.
