Little is known about the extent to which information encoding and retrieval differ between materials studied in first and second language (L1 and L2). In this study we compared memory for short, expository texts in L1 and L2, tested with a free recall test and a true/false judgement test. Our results show that students performed at the same level on the recognition test in both languages but not on the free recall test, with much lower performance in L2 than in L1, defined here as the dominant language. The L2 recall cost suggests that students’ performance may be underestimated if they are exclusively tested with essay-type exams in L2.
