| Abstract: | Leonard Krasner was a psychologist with a degree in experimental psychology. He was known for his influential review of verbal conditioning studies that were published in Psychological Bulletin. After collaborating with a student, Leonard Ullmann, the two Lens began a collaboration that lasted more than 20 years. Their early work on verbal conditioning was followed, in 1965, by two landmark books: Case studies in behavior modification and Research in behavior modification. The books announced the term "behavior modification" and featured the work of many friends Len Krasner had made and invited to the Palo Alto VA to give presentations. In 1969 they published A psychological approach to abnormal behavior, which was the first, and is still the best, behavioral book on the topic. They followed that in 1973 with Behavior influence and personality, which remains one of the best integrative textbooks, combining sociological and behavioral perspectives. Leonard Krasner died November 28, 2007, in Reno, Nevada. (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
