VAN NOSTRAND INSIGHT BOOKS
Insight Books are devoted to filling a vital need in the efficient study of human behavior. By making available, in paperback, essential materials that are frequently inaccessible or often neglected in a more expensive form, the Insight Series renders a valuable service to students, teachers, and interested laymen. Drawn from psychology and its allied fields, the bulk of the books published will deal with the following categories: 1) studies of enduring problems in psychology through original sources; 2) selections from their own works by contemporary behavioral scientists; and 3) authoritative discussions of timely, even controversial, issues.
