This study determined which study habits would distinguish successful from unsuccessful foreign language learners. Participants were 219 college students from a variety of disciplinary backgrounds enrolled in either Spanish, French, German, or Japanese classes. The students completed the Study Habits Inventory and the Background Demographic Form. A canonical discriminant analysis revealed that, compared to their high-performing counterparts, students with the lowest levels of foreign language performance tended to report the following: (1) they frequently included a lot of irrelevant or unimportant information in their notes; (2) when they had difficulty with their assignments, they did not seek help from their instructor; (3) they put their lecture notes away after taking the test and never consulted them again; (4) they had to be in the mood before attempting to study; (5) they had a tendency to doodle or daydream when they were trying to study; and (6) they did not look up in a dictionary the meaning of words that they did not understand.
