FROM THE PREFACE: The present work is the result of a series of connected studies, starting with some exploratory investigations in Oslo in 1956, continued in terms of a series of experiments in Minneapolis 1956-57, and followed up by a program for experimental research in Oslo 1957-58. The common core of the empirical studies, though, is a new kind of research instrument that was first tried out in Minneapolis during the fall of 1956. By constructing material representing stimulus persons systematically distributed in an "attribute surface" and by having subjects rank these artificially composed persons as potential friends, the author began accumulating new and interesting experimental evidence of particular relevance to the understanding of selective and intuitive social perception.
