This study conducted at the University of Kentucky in 1967-68 tests the theory of interaction between discrimination and pronunciation through a field test. After a brief review of previous research in phonemic discrimination as related to foreign language learning, the procedures and results of the test are presented. The text used was "Basic French: A Programmed Course" by Mueller and Niedzieldski. A quantitative analysis and impressionistic evaluation of the test are included, and there is discussion of the procedures and variables involved. It is concluded that discrimination training seems to be an effective training device in the learning of pronunciation. (JH)
