The data that provide the foundation for this investigation of second language (L2) slips ofthe tongue stem from a corpus originally compiled in 1984 to investigate the use of compensatorystrategies by Dutch learners of English. Poulisse defines a slip or speech error as a performanceerror stemming from a temporary processing problem rather than a competence error reflecting anincomplete or incorrect L2 system. The book's focus is the extent to which research on L2slips (morphological, phonological, and syntactic) can shed light on speech-production processingfor the development of bilingual models of speech production.
