In this series of three articles, the work of Rapaport is reviewed in the light of present-day thinking. Mayman, dealing with theory, gives Rapaport credit for his great contributions to metapsychology, but feels that the preoccupation of the past with metapsychology is nearing its end with the emergence of a more carefully systematized clinical theory. Shevrin, in reviewing recent research findings on attention, memory scanning, binocular rivalry, stopped retinal image, and the neurophysiological correlates of consciousness sees considerable support for the existence of a psychological unconscious. He points out that this research comes from far afield and that psychoanalysis should not constrain its research only to the treatment situation at a time when new doors are opening in many areas. Appelbaum pays tribute to Rapaport for building a foundation for the practice of those doing psychological testing. In addition, he reviews the advances made by others since Rapaport's contribution to that field.
