Research on input processing (IP) to date has focused largely on sentences and acquisition of morphosyntax. Other research has addressed IP at the lexical level for different aspects of vocabulary acquisition. This chapter clarifies how understanding multilevel IP can improve our understanding of IP across the board. Section 1 defines multilevel IP and clarifies its overarching role when learners are exposed to input. Section 2 summarizes research on sentence-level IP and identifies areas in which research on lexical IP can be informative. Section 3 summarizes research on lexical IP, noting areas in which research on sentence-level IP can be informative. Finally, Section 4 discusses challenges to be met in new efforts to investigate and advance theory related to multilevel IP.
