Abstract The present study examined the impacts of corrective feedbacks on the perception and production of English tense-lax vowel contrast /i/-/I/. 100 non-English major freshmen were randomly assigned to one of three experimental groups (recast, elicitation or elicitation + recast) or a control group. The present study employed a pre-test, 6 perception-based treatment interactional activities, an immediate post-test and a delayed post-test. The participants’ speech performance was measured by perception, controlled and spontaneous tests. The results show that: 1) as for both the trained and untrained items, recasts, elicitations and elicitations + recasts all had beneficial effects on the Chinese EFL learners’ perception of English target vowel contrast in the /i/-/I/, and there was no significant difference among the corrective feedback types, 2) as for both the trained and untrained items, recasts and elicitations + recasts demonstrated significantly superior effects than elicitations on the Chinese EFL learners’ production of English target vowel contrast /i/-/I/.
Key words: corrective feedback; English tense-lax /i/-/I/ vowel contrast; perception; production
