This chapter consists of three parts. First, a quantitative analysis of the history of psychological gerontology will be given based upon the reconstructed flow of written information in reference networks. Second, this analysis will be supplemented by more traditional, idiographic interpretations, focusing especially on those "underdeveloped" areas not represented in the networks, and deducing conclusions from comparisons with the general area of developmental psychology. Third, in view of the enormous amount of wasted research efforts (noted in the first part) and the concurrent lack of investigations of significant issues (noted in the second part), questions need to be raised concerning our concepts of research and theory, communication and education, and, more generally, our conception of man, society, and their development.
QUANTITATIVE ANALYSIS OF THE HISTORY OF PSYCHOLOGICAL GERONTOLOGYWith the exception of recent reports by Birren (1961) and Munnichs (1966) on psychological gerontology and those by Charles Klaus F. Riegel received his PhD in psychology at the University of Hamburg, West Germany, 1957. Since 1959, he has been a Professor of Psychology a t the University of Michigan. His major interest and orientation are in cognitive changes during old age. Presently, the author is working on two books, one dealing with the acquisition of meaning and the other, with developmental and historical structuralism.
