Research interests

The primary goal of Professor Sprouse's research is to gain a better understanding of the adult nonnative language paradox: Why is that adults exposed to a nonnative language develop systems of linguistic knowledge of a startlingly rich and complex nature, including properties for which there is little or no evidence in the input (“poverty/bankruptcy of the stimulus”), while still (in a large percentage of cases) experiencing significant difficulty in the acquisition and use of relatively “simple” features of word choice and form? Professor Sprouse is best known in second language studies for proposing (together with Bonnie D. Schwartz, University of Hawaii) the Full Transfer/Full Access hypothesis and for pioneering (together with Laurent Dekydtspotter, Indiana University) research on the syntax-semantics interface in English-French interlanguage. He is currently developing the Deep Lexical Transfer Hypothesis, which a re-conceptualizes Full Transfer in terms of relexification/relabeling in the sense that Claire Lefebvre (Université du Québec à Montréal) has used these terms to describe creole genesis. In current work, Professor Sprouse, together with his students in the Comparative and Diachronic Syntax Lab at IU and with his long-time collaborator Prof. Bonnie D. Schwartz, are considering the role of previously acquired grammars in the acquisition of third or additional languages. Professor Sprouse is also considering ways in which the Language Instinct becomes “blunted” over the course of the life span, even though the fundamental architecture of grammars and processing mechanisms remains untouched.

An additional research topic for Professor Sprouse is the role on multilingualism in morpho-syntactic change.
