Swain's (1985, 1995, 2000) output
hypothesis states that language production is facilitative of second
language (L2) learning. An important component of the output hypothesis
involves pushing learners to produce appropriate, accurate,
and complex language (Swain, 1993), which may
occur when interlocutors provide learners with negative feedback (Gass,
1997, 2003; Long, 1996; Mackey, in press;
Pica, 1994; Swain &
Lapkin, 1995). When learners modify their previous utterances in
response to negative feedback, learning opportunities are created by
both the provision of negative feedback and the production of modified
output. Consequently, it is difficult to determine how these
interactional features—alone or in combination—positively
impact L2 development. The current study examines the impact of
negative feedback and learners' responses on English as a second
language (ESL) question development, which is operationalized as stage
advancement in Pienemann and Johnston's developmental sequence for
ESL question formation (Pienemann & Johnston,
1987; Pienemann, Johnston, & Brindley,
1988). Thai English as a foreign language (EFL) learners
(n = 60) carried out a series of communicative tasks with
native English speakers in four conditions that provided different
negative feedback and modified output opportunities and also completed
four oral production tests over an 8-week period. Analysis of the
treatment data identified the amount of modified output involving
developmentally advanced question forms produced by the learners, and
analysis of the test data revealed whether the learners' stage
assignment changed over time. Logistic regression indicated that the
only significant predictor of ESL question development was the
production of modified output involving developmentally advanced
question forms in response to negative feedback.I am grateful to Alison Mackey for her insightful comments
