The paper summarizes four presentations made by members of the Pennsylvania State University Program for Learning Disabled (LD) students. An initial section considers the definition of LD and reviews a study on diagnosing LD in 12 undergraduates. The existence of a foreign language disability in students with good attitudes toward learning a foreign language, but who have repeatedly failed foreign language courses, is discussed, and analysis of scores on the Modern Language Aptitude Test are analyzed. A study to develop norms for evaluating written expression is described. Intervention programing is said to include procedures based on behavioral theories as well as availability of special equipment on a long term basis. Intervention is programed according to the amount of structure needed by the student. (CL)
