Skinner’s Theory of Operant Conditioning and Behavior Modification Theory: Behaviorism Theorist: B.F. Skinner Biography: B.F Skinner was considered to be the father of the behavioral approach to psychology, due to his prominence as a spokesperson for behaviorism (Corey, 2009). B.F. Skinner was born in 1904 (Corey, 2009). Skinner recalled his upbringing as being a warm and stable family environment (Corey, 2009). In the 8th edition of Theory and Practice of Counseling and Psychotherapy, Gerald Corey, Ph.D. (2009) wrote that Skinner, while growing up, had a great interest “in building all sorts of things, an interest that followed him throughout his professional life” (p. 233). In 1931, Skinner graduated from Harvard University with a Ph.D. in psychology (Corey, 2009). Skinner taught at several other universities, but eventually returned to Harvard (Corey, 2009). Skinner had two daughters; one became an educational psychologist and the other an artist (Corey, 2009). Theory Description: Throughout his career, Skinner was a strong proponent of “radical behaviorism;” in which, a primary emphasis is placed on behavior being impacted by the effects of environment (Corey, 2009). Skinner acknowledged the existence of feelings and thoughts; but, also posited that they did not cause the actions of humans; instead, it is the environment (Corey, 2009). Moreover, he theorized that there are “cause and effect links between objective, observable environmental conditions and behavior” (Corey, 2009, p. 233). Skinner maintained that the 1 internal states of mind and motives on which psychoanalytic approaches are based, such as those of Sigmund Freud and Erik Erikson, cannot be directly observed or changed received too much attention (Corey, 2009). Conversely, he felt environmental factors that could be observed and changed (behaviorism) received too little focus (Corey, 2009). Jennifer L. Stoll (2004) in her Chapter 7 contribution to the book, Counseling Theories and Techniques for Rehabilitation Health Professionals posits that behaviorism or behavior therapy itself is not just one approach to psychological therapy, but rather, a collection of approaches and techniques which are used to change behaviors from maladaptive to adaptive ones. However, they differ in the manner in which the technique delivers the therapeutic treatment (Stoll, 2004). In addition, Stoll (2004) posits that, all behavioral approaches share three common characteristics: 1. Emphasis is placed upon: Current behavior rather than focusing on past behavior (Corey, 2001; Wilson, 2000) Thus behavior theorists treat the behavior itself rather than underlying hypothesized causes of behavior; this represents a marked contrast to more traditional models of psychotherapy (e.g. psychoanalysis), which focus on the past or historical events that contribute to the development and manifestation of maladaptive behavior. (Stoll, 2004, p. 136) 2. Behavioral therapies utilize a scientific approach to the evaluation of the treatments’ effectiveness by setting clearly defined, objective, measurable goals (Stoll, 2004). 3. Throughout the treatment process, multiple assessments of the effectiveness are conducted (Stoll, 2004). 2 Moreover, Stoll also writes the following: In addition to the three central commonalities identified above, Rotgers (1996) identified seven assumptions of behavior therapy: (1) human behavior is largely learned rather than determined by genetics; (2) the same learning processes that create maladaptive behaviors can be used to change or eliminate them; (3) behavior is predominantly determined by contextual and environmental mediators; (4) covert behaviors, such as thoughts and feelings are subject to change through the implementation of learning processes; (5) actual performance of new behaviors in the contexts in which they are to be performed is a critical aspect of behavior change; (6) each client is unique and requires an individualized assessment of inappropriate behavior; and (7) the cornerstone of successful treatment is a thorough behavioral assessment. (Stoll, 2004, p. 136) Finally, Stoll (2004) writes that there are three distinct approaches to behavior therapy, of which, all are aimed at “accomplishing the same ultimate goals of reducing inappropriate behaviors and increasing appropriate behaviors” (Stoll, 2004, p. 137). These approaches are classical conditioning, operant conditioning and cognitive-behavioral approaches (Stoll, 2004). Theory’s Components: For purposes of this paper, the remainder of the discussion will center on B.F. Skinner and operant conditioning. Most of Skinner’s work concentrated upon the concept of operant conditioning. For Skinner, the notion of reinforcement is central to operant conditioning. His contention was that learning could not: 3 Occur in the absence of some kind of reinforcement, either positive or negative. Reinforcement involves some kind of reward or the removal of an aversive stimulus following a response. Reinforcement takes place when the consequences of a behavior increase the likelihood that the behavior will be repeated (Corey, 2005, p. 230). Corey writes further that for Skinner there was the belief that actions “that are reinforced tend to be repeated, and those that are not reinforced tend to be extinguished” (Corey, 2005, p.230). Thus, Corey posits that operant conditioning refers to “a type of learning in which behaviors are influenced mainly by the consequences that follow them” (Corey, 2005, p. 230). If the environmental changes produce no reinforcement or produce aversive stimuli, the chances are lessened that the behavior will recur (Corey, 2005). Skinner performed his work in the laboratory and it was experimental in nature; but, others that followed (such as, Albert Bandura) “applied his ideas to teaching, managing human problems, and social planning (Corey, 2005, p. 227)” The aforementioned applications occurred through the use of positive and negative reinforcement, punishment, and extinction techniques (Corey, 2005)”. Skinner’s writings, such as, Science and Human Behavior (1953) and Walden Two (1948), best illustrate his belief in the application of behavioral concepts to human endeavors.
