This is a study of instances of negative transfer attributable to interference of Texas English with German. It is intended for use as a supplement to William G. Moulton's The Sounds of English and German in teaching German in Texas. The system of stressed vowels of Texas English is presented for comparison and contrast with the stressed vowel system of Modern High German. There follows a contrastive analysis section, which discusses difficulties the Texas student is likely to experience in pronouncing German, based upon conflict between the two systems of stressed vowels. Finally, a discussion is offered of how the instructor of German can best deal with those instances of negative transfer, and specific corrective drills are formulated.
