The document reports the proceedings of a conference on "Theory and Methods of Research on Aging" held under the auspices of the Division of Maturity and Old Age of the American Psychological Association, the Department of Psychology and the Human Resources Research Institute of West Virginia University, May 17-19, 1967. The summaries of four speeches and of the ensuing floor discussions on all are presented. McFarland Discusses the status of perception and aging and includes sensory as well as perceptual processes. Kay's paper restricts the field of learning largely to that of the memory functions. The paper by Bayley on the topic of cognition also limits the field of discussion by attending primarily to the basic components of standard tests of intelligence, such as reasoning, problem-solving, information, and complex measures of memory function. She bases her analysis of the art on a description of data and issues arising out of the Berkeley growth studies. In the fourth primary paper Chown discusses the current status of work in personality and aging. She organizes her discussion around two major trends, the work on disengagement theory and life style and the more isolated pursuits of age differences on a large variety of particular test and inventory type measures of personality.
