Multilevel Measurement of Interpersonal Behavior.
Berkeley: Psychological Consultation Service, 1956.
4to. Softbound (only issued softbound). First edition of Leary's first solely-authored book (preceded only by a play he co-wrote in college in 1942). Written in conjuction with his first full-length book, Interpersonal Diagnosis of Personality, but published before it, this book is the result of Leary's experiments in interpersonal behavior at the Kaiser Foundation in Oakland in the '50s. It helped to establish Leary as one of the most important thinkers in the field, eventually leading to his position at Harvard. The tests Leary designed for this book were given to Leary himself when he was imprisoned. Brief ink name to corner of front cover, faint ring stain to front cover, a couple of pages have a single word in ink and a couple have some minor pencil writing, still, overall, a very good copy of an important early item that rarely surfaces in fine condition.
