INPUT, INTERACTION, AND SECOND LANGUAGE DEVELOPMENT An Empirical Study of Question Formation in ESL Alison Mackey Georgetown University This study examines the relationship between different types of con- versational interaction and SLA. Long's (1996) updated version of the interactionist hypothesis claims that implicit negative feedback, which can be obtained through negotiated interaction, facilitates SLA. Similar claims for the benefits of negotiation have been made by Pica (1994) and Gass (1997). Some support for the interaction hypothesis has been provided by studies that have explored the effects of interaction on production (Gass & Varonis, 1994), on lexical acquisition (Ellis, Tanaka, & Yamazaki, 1994), on the short-term outcomes of pushed output (see Swain, 1995), and for specific interactional features such as recasts (Long, Inagaki, & Ortega, 1998; Mackey & Philp, 1998). However, other studies have not found effects for interaction on gram- matical development (Loschky, 1994). The central question ad- dressed by the current study was: Can conversational interaction facilitate second language development? The study employed a pre- test-posttest design. Adult ESL learners (N = 34) of varying L1 back- grounds were divided into four experimental groups and one control I am grateful to Susan M. Gass and Charlene Polio for insightful suggestions and help with this paper. I also want to thank Patsy Lightbown, Michael H. Long, Teresa Pica, and Merrill Swain for many helpful comments on the doctoral dissertation from which this paper arose. I am much indebted to Ian Thornton for assistance with the statistical analysis and discussions of many of the issues in- volved in this study.
