This report is a continuation of a research project, begun by B. Spolsky and E. Migliazza in the English as a Foreign Language Program at Indiana University, designed to show that foreign students whose overall integrative motivation is high (+IM) have achieved a higher standard of English proficiency than those whose integrative motivation is low (-IM). The purpose of this report is to relate the English proficiency and bicultural attitudes of Japanese students who have all studied English for about the same length of time in Japan. The equipment used for testing consisted of a taped interview from which was derived an English proficiency score and two questionnaires designed to measure degrees of integrative motivation. The first questionnaire listed 30 adjectives which are traits in a person's value system. The second questionnaire listed reasons for coming to America; students indicated the importance of each reason. Figures based on the results show--(1) Students with a high total English score tend to have a +IM sign; (2) Length of stay in America is not a significant factor in determining whether a student has a + or -IM sign; (3) There is no positive relationship between reasons for coming to America and English ability; and (4) Most of the students considered learning English "rather important." This had no relationship to their English score, however. The final conclusion is that Japanese students with high IM--who tend to become somewhat "Americanized"--tend to become better speakers of English. (AMM)
