Genetic Factors in Behaviour BEHAVIORAL AND BRAIN SCIENCES (1986) 9, 687-724 Printed in the United States of America Precis of Behaviorism: A conceptual reconstruction G. E. Zuriff Department of Psychology, Wheaton College, Norton, Mass. 02766 Abstract: The conceptual framework of behaviorism is reconstructed in a logical scheme rather than along chronological lines. The resulting reconstruction is faithful to the history of behaviorism and yet meets the contemporary challenges arising from cognitive science, psycholinguistics, and philosophy. In this reconstruction, the fundamental premise is that psychology is to be a natural science, and the major corollaries are that psychology is to be objective and empirical. To a great extent, the reconstruction of behaviorism is an elaboration of behaviorist views of what it is for a science to be objective and empirical. The reconstruction examines and evaluates behaviorist positions on observation and the rejection of introspection, the behavioral data language, theory construction, stimulus-response psychology, the organization of behavior, complex processes, agency, and the interpretation of mentalistic language. The resulting reconstruction shows behaviorism to be a pragmatic psychological version of positivism based on a behavioral epistemology.

    ARTICLE IN PRESS + MODEL International Journal of Psychophysiology xx (2006) xxx–xxx www.elsevier.com/locate/ijpsycho The role of theory in the psychophysiology of personality: From Ivan Pavlov to Jeffrey Gray ⁎ Philip J. Corr , Adam M. Perkins Department of Psychology, University of Wales Swansea, Singleton Park, Swansea SA2 8PP, UK Received 16 June 2005; received in revised form 24 October 2005; accepted 5 January 2006 Abstract Psychophysiological approaches to personality have made significant progress in recent years, partly as a spin-off of technological innovation (e.g., functional neuroimaging) and partly as a result of an emerging theoretical consensus regarding the structure and biology of basic processes. In this field, Jeffrey Gray's influential psychophysiological theory of personality – now widely known as Reinforcement Sensitivity Theory (RST) – owes much to Pavlov, who devoted a large proportion of his later life to personality differences and their implications for psychiatry. In this article, we trace the influence of Pavlov on Hans Eysenck's and Jeffrey Gray's work, and then provide a brief description of RST in order to highlight some of the central problems – as well as some tentative solutions – in the psychophysiology of personality. Specifically, the importance of theory in personality research is stressed by the contrast of Gray's theoretically driven model with less fertile atheoretical (i.e., exploratory–inductive) approaches. The fecundity of RST, which has been in continual development over a period of thirty years, is discussed in the light of Karl Popper's views on the nature of science, especially the formulation of the ‘problem situation’, which sets up the theoretical and operational conditions under which hypotheses may be challenged and tested to destruction.

  • Behavior Therapy Is Behavioristic
    BEHAVIORTHERAPy ( 1972 ) 3, 609-613 I~ESPONSES AND I~EJOINDER Behavior Therapy Is Behavioristic HANS J. EYSENCK1 University of London This article tries to answer an objection sometimes raised by critics of behavior therapy, namely, flaat it is not "behavioristic." The objection is shown to be ungrounded and dependent on an outmoded use of the term "behaviorism." "Is "behavior therapy" behavioristic?" asked Locke (1971), and con- cluded that the answer is in the negative. One feels inclined to quote in reply Sir Francis Bacon (Dicks, 1955, p. 182), who wrote that it is "The first distemper of learning, when men study words and not matter." Locke brought into juxtaposition two terms, "behavior therapy" and "behavior- ism"; in order to form a judgment of their compatibility, one must first arrive at a definition of both which would not be arbitrary, but widely agreed. By using his own arbitrary definitions Locke was able to make a case; I shall try to show just how arbitrary the definitions are. According to Locke, the term "behavior therapy" was coined by Skinner and Lindsley (1954), and "has since been widely promulgated by Eysenck (1960, 1964)." This is incorrect; the term was "coined" inde- pendently by at least three people or groups, namely, the two mentioned above, and by Lazarus (1958). Its use by Skinner and Lindsley was con- fined to a Status Report to the Office of Naval Research, and never pub- lished; it was not familiar to either of the other two authors. Furthermore, it referred entirely to operant methods of treatment, a restriction which makes it clear that its use was quite different from that intended by Eysenck (1959), who explicitly established its present usage as referring to all methods of therapy which are based on modern learning theory-- thus including both the Skinnerian operant methods and Wolpe's desen- sitization method, as well as many others (Eysenck, 1960).

  • Personality Associations with Mood, Hoarding, Health and Well-Being Janet Katherine Spittlehouse
    Personality Associations with Mood, Hoarding, Health and Well-being Janet Katherine Spittlehouse A thesis submitted for the degree of Doctor of Philosophy Department of Psychological Medicine University of Otago, Christchurch New Zealand 31 August 2016 Abstract Background: Personality has been of interest since ancient times. Hippocrates, also known as ‘The father of Western Medicine’ was possibly the first to document the association between personality and mental and physical health by describing the ancient medical theory of Humourism. Over the last 100 years the study of personality has been evolving and there are many different perspectives. Trait perspectives have become popular but they lack any underlying theory about how personality develops. Psychobiological models offer descriptions of personality and provide testable theories on how biology influences their development. A robust psychobiological model is Cloninger’s psychobiological theory and it provided the basis for this project. Objectives: This project explored the associations of personality in different mental health settings using the Temperament and Character Inventory (TCI; Cloninger, Przybeck, Svrakic, & Wetzel, 1994), the personality inventory developed by Cloninger and colleagues, that is suitable for measuring both normal and abnormal personality. The TCI was used to examine the impact of depression on personality measurement and personality associations to self-reported physical and mental health, mood disorders, hoarding behaviours and well-being. Methods: Participants for this project were from three studies. Two randomised clinical trials designed to examine predictors of treatment response for depressed outpatients using either antidepressant medication (N=195) or psychotherapy (N=177) were used to examine the impact of depression on measures of personality.

  • Introduction to Political Psychology
    INTRODUCTION TO POLITICAL PSYCHOLOGY This comprehensive, user-friendly textbook on political psychology explores the psychological origins of political behavior. The authors introduce read- ers to a broad range of theories, concepts, and case studies of political activ- ity. The book also examines patterns of political behavior in such areas as leadership, group behavior, voting, race, nationalism, terrorism, and war. It explores some of the most horrific things people do to each other, as well as how to prevent and resolve conflict—and how to recover from it. This volume contains numerous features to enhance understanding, includ- ing text boxes highlighting current and historical events to help students make connections between the world around them and the concepts they are learning. Different research methodologies used in the discipline are employed, such as experimentation and content analysis. This third edition of the book has two new chapters on media and social movements. This accessible and engaging textbook is suitable as a primary text for upper- level courses in political psychology, political behavior, and related fields, including policymaking. Martha L. Cottam (Ph.D., UCLA) is a Professor of Political Science at Washington State University. She specializes in political psychology, inter- national politics, and intercommunal conflict. She has published books and articles on US foreign policy, decision making, nationalism, and Latin American politics. Elena Mastors (Ph.D., Washington State University) is Vice President and Dean of Applied Research at the American Public University System.

Eating withuut punishment was called the “normal” reaction: eating with shock was called the “psychopathic” rc:lction. and not eating, even when safe, was called the “dysthymlc” reaction.

  • Personality and Experimental Psychology: the Unification of Psychology and the Possibility of a Paradigm
    PERSONALITY PROCESSES AND INDIVIDUAL DIFFERENCES Personality and Experimental Psychology: The Unification of Psychology and the Possibility of a Paradigm Hans J. Eysenck Institute of Psychiatry It is suggested that the scientific status of psychology is put in danger by the lack of paradigms in many of its fields, and by the failure to achieve unification, psychology is breaking up into many different disciplines. One important cause was suggested by Lee Cronbach in his 1957 presidential address to the American Psychological Association: the continuing failure of the two scientific disciplines of psychology—the experimental and the correlational—to come together and mutually support each other. Personality study in particular has suffered from this disunity, and the debates about the number of major dimensions of personality illustrate the absurdity of the situation. Examples are given to show that by combining methods and theories typical of these two disciplines, one can put forward paradigms that would be impossible without such unification. Such a paradigm is suggested for personality and intelligence. There is a good deal of agreement among philosophers of variance (Eysenck, 1964, 1965). I have also suggested that the science that a mature science is characterized by the existence failure of personality psychology to achieve paradigmatic status of paradigms, indicated by the presence of exemplars and disci- may be due to its failure to link findings and theories to the plinary matrices (Kuhn, 1974), that is, a scientific theory to- knowledge acquired by experimental psychology (Eysenck, gether with examples of successful and striking applications, 1994; Eysenck & Eysenck, 1985).

  • The Outcome of Psychotherapy: Yesterday, Today and Tomorrow
    Te outcome of psychotherapy: Yesterday, today and tomorrow SCOTT D. MILLER, MARK A. HUBBLE, DARYL L. CHOW and JASON A. SEIDEL In 1963, the first issue of the journal Psychotherapy appeared. Responding to findings reported in a previous publication by Eysenck (1952), Strupp wrote of the ‘staggering research problems’ confronting the field and the necessity of conducting ‘properly planned and executed studies’ to resolve questions about the process and outcome of psychotherapy. Today, both the efficacy and effectiveness of psychotherapy has been well established. Despite the consistent findings substantiating the field’s worth, a significant question remains the subject of debate: How does psychotherapy work? On this subject, debate continues to divide the profession. In this paper, a ‘way out’ is proposed informed by research on the therapist’s contribution to treatment outcome and findings from studies on the acquisition of expertise. ‘If we want to solve a problem that we have never solved before, we must leave the door to the unknown ajar.’ Richard P.
