First published in 1996. The field of behavior analysis began with the research studies of B.F. Skinner in the 1930s. In 1950, Keller and Schoenfeld published Principles of Psychology. It was the first text to present the basic principles of behavior analysis in a systematic fashion. While continuing to cite and describe the seminal articles in the field, in this book Leslie also includes clear presentations of new findings. The systematic presentation of these findings enables the author to provide laboratory based accounts of increasingly complex forms of human behavior, instead of plausible extrapolations which were the only option available at an earlier time. The Principles of Behavior Analysis does not sacrifice sweep for detail, and also does not sacrifice adequate presentation of basic principles for oversimplification.

This book discusses the development of Edward Tolman's purposive behaviourism from the 1920s to the 1950s, highlighting the tension between his references to cognitive processes and the dominant behaviourist trends. It shows how Tolman incorporated concepts from European scholars, including Egon Brunswik and the Gestalt psychologists, to justify a more purposive form of behaviourism and how the theory evolved in response to the criticisms of his contemporaries. The manuscript also discusses Tolman's political activities, culminating in his role in the California loyalty oath controversy in the 1950s. Tolman was involved in a number of progressive causes during his lifetime, activities that drew the attention of both state legislators in California and the Federal Bureau of Investigation. It treats Tolman's theoretical and political activities as emanating from the same source, a desire to understand the learning process in a scientific manner and to apply these concepts to improve the human condition.

Originally published in 1924, this book--as the title suggests--provides an overview of the principles of psychology. Written at a time when psychology was a "youthful" science and the debate over the field's status as a natural science (or even as a science at all) was relatively fresh, Principles of Psychology represents a stock-taking of sorts--a survey of the ends achieved and the newer trends of development in psychological research. The author's aim is to present and study psychological phenomena as actual, observable events consisting of the responses of psychological organisms on the one hand, and the stimulus objects or conditions which interact with them on the other. By dispensing with animatistic conceptions and intangible psychic phenomena that previously dominated the field, the author hopes to bolster psychology's position as a member of the family of natural sciences. According to the author, only by avoiding meticulously all powers or functions--whether considered as psychic or biological--which do not represent actual observable phenomena or interpretations derived from such observations, can psychology as a science be erected upon a firm foundation. It is to this end that the author presents 15 chapters on a wide range of topics that represent the core concepts and principles of psychology: The Domain, Method, and Development of Psychology; The Primary Data of Psychology; The Psychological Individual or Personality; The Psychological Organism or Personality in Action; The Simpler or Foundation Behavior Segments; The Nature of Basic Conduct and How it is Developed; The Development and Operation of Complex Human or Societal Conduct; Attention Behavior as the Actualization of Stimuli; The Nature of Sensing and Perceiving; Implicit Action as Responses to Absent Stimuli Objects; Association as a Fundamental Type of Psychological Activity; The Primary Internal Character of Feeling Reactions; Knowing as Determining and Orientating Conduct; The Nature of Volitional Conduct; and, finally, The Integrative Nature of Habit Reactions.

Originally published in 1985, this book was an attempt at a comprehensive review of the psychology of action in various areas of psychology. It is also an attempt to bridge two languages and traditions in psychology: German and Anglo-American. Although Anglo-American psychology had had an enormous influence on German psychology, the influence had not gone the other way around – at least not in recent years. Therefore, this book attempts to get the two traditions to speak with each other. The main article, from one language area, and the following discussion, from the other language area, together result in an extensive treatment of an action-theoretic approach in the respective psychological area; thus, both the main article and "discussion" should be read together.
