This task group report is one of a series prepared by eminent psychologists who have served as consultants in the U.S.O.E.-sponsored grant study to conduct a Critical Appraisal of the Personality-emotions-Motivation Domain. In order to achieve the goal of identifying important problems and areas for new research and methodological issues related to them, an approach was followed in which leading investigators in specialized areas were enlisted as members of task groups and asked to reflect in their current knowledge of ongoing research and to identify the research needs in their respective areas. The titles of the articles in this volume are: Interests and Vocational Guidance (Campbell); Research Suggestions for Interest Test Interpretation (Sharf); Interests and Vocational Guidance (Harmon); and Interests and Vocational Guidance (Zytowski).
