This study attempts to test aspects of the input hypothesis (Krashen, 1980, 1983, 1985) and Long's modification of it (Long, 1980, 1983a, 1985). Specifically, it experimentally tests the hypothesis that both input and interactional modifications facilitate second language acquisition, using Japanese as the target language. Three experimental groups were differentiated in terms of input and inte...
