Behaviorism is a systematic approach to understanding the behavior of humans and other animals. It assumes that behavior is either a reflex elicited by the pairing of certain antecedent stimuli in the environment, or a consequence of that individual's history, including especially reinforcement and punishment contingencies, together with the individual's current Motivation and Stimulus control. Although behaviorists generally accept the important role of heredity in determining behavior, deriving from Skinner's two levels of selection (phylogeny and ontogeny), they focus primarily on environmental events. The cognitive revolution of the late 20th century largely replaced behaviorism as an explanatory theory with cognitive psychology, which unlike behaviorism views internal mental states as explanations for observable behavior.
Behaviorism emerged in the early 1900s as a reaction to depth psychology and other traditional forms of psychology, which often had difficulty making predictions that could be tested experimentally. It was derived from earlier research in the late nineteenth century, such as when Edward Thorndike pioneered the law of effect, a procedure that involved the use of consequences to strengthen or weaken behavior.
With a 1924 publication, John B. Watson devised methodological behaviorism, which rejected introspection and sought to understand behavior by only measuring observable behaviors and events. It was not until 1945 that B. F. Skinner proposed that covert behavior—including cognition and —are subject to the same controlling variables as observable behavior, which became the basis for his philosophy called radical behaviorism. While Watson and Ivan Pavlov investigated how (conditioned) neutral stimuli elicit reflexes in respondent conditioning, Skinner assessed the reinforcement histories of the discriminative (antecedent) stimuli that emits behavior; the process became known as operant conditioning.
The application of radical behaviorism—known as applied behavior analysis—is used in a variety of contexts, including, for example, applied animal behavior and organizational behavior management to treatment of mental disorders, such as autism and substance abuse. In addition, while behaviorism and cognitive schools of psychological thought do not agree theoretically, they have complemented each other in the cognitive-behavioral therapies, which have demonstrated utility in treating certain pathologies, including simple , PTSD, and mood disorders.
Although John B. Watson mainly emphasized his position of methodological behaviorism throughout his career, Watson and Rosalie Rayner conducted the infamous Little Albert experiment (1920), a study in which Ivan Pavlov's theory to respondent conditioning was first applied to eliciting a fearful reflex of crying in a human infant, and this became the launching point for understanding covert behavior (or private events) in radical behaviorism; however, Skinner felt that aversive stimuli should only be experimented on with animals and spoke out against Watson for testing something so controversial on a human.
In 1959, Skinner observed the emotions of two pigeons by noting that they appeared angry because their feathers ruffled. The pigeons were placed together in an operant chamber, where they were aggressive as a consequence of previous reinforcement in the environment. Through stimulus control and subsequent discrimination training, whenever Skinner turned off the green light, the pigeons came to notice that the food reinforcer is discontinued following each peck and responded without aggression. Skinner concluded that humans also learn aggression and possess such emotions (as well as other private events) no differently than do nonhuman animals.
Skinner's empirical work expanded on earlier research on trial-and-error learning by researchers such as Thorndike and Guthrie with both conceptual reformulations—Thorndike's notion of a stimulus-response "association" or "connection" was abandoned; and methodological ones—the use of the "free operant", so-called because the animal was now permitted to respond at its own rate rather than in a series of trials determined by the experimenter procedures. With this method, Skinner carried out substantial experimental work on the effects of different schedules and rates of reinforcement on the rates of operant responses made by rats and pigeons. He achieved remarkable success in training animals to perform unexpected responses, to emit large numbers of responses, and to demonstrate many empirical regularities at the purely behavioral level. This lent some credibility to his conceptual analysis. It is largely his conceptual analysis that made his work much more rigorous than his peers, a point which can be seen clearly in his seminal work Are Theories of Learning Necessary? in which he criticizes what he viewed to be theoretical weaknesses then common in the study of psychology. An important descendant of the experimental analysis of behavior is the Society for Quantitative Analysis of Behavior.
Skinner did not respond in detail but claimed that Chomsky failed to understand his ideas, and the disagreements between the two and the theories involved have been further discussed. Innateness theory, which has been heavily critiqued, is opposed to behaviorist theory which claims that language is a set of habits that can be acquired by means of conditioning. According to some, the behaviorist account is a process which would be too slow to explain a phenomenon as complicated as language learning. What was important for a behaviorist's analysis of human behavior was not language acquisition so much as the interaction between language and overt behavior. In an essay republished in his 1969 book Contingencies of Reinforcement, Skinner took the view that humans could construct linguistic stimuli that would then acquire control over their behavior in the same way that external stimuli could. The possibility of such "instructional control" over behavior meant that contingencies of reinforcement would not always produce the same effects on human behavior as they reliably do in other animals. The focus of a radical behaviorist analysis of human behavior therefore shifted to an attempt to understand the interaction between instructional control and contingency control, and also to understand the behavioral processes that determine what instructions are constructed and what control they acquire over behavior. Recently, a new line of behavioral research on language was started under the name of relational frame theory.Blackledge, J. T. (2003). An introduction to relational frame theory: Basics and applications. The Behavior Analyst Today, 3(4), 421-433.[2]Martin O'Connor, Lynn Farrell, Anita Munnelly, Louise McHugh. (2017).

The following descriptions explains the concepts of four common types of consequences in operant conditioning:
A classical experiment in operant conditioning, for example, is the Skinner Box, "puzzle box" or operant conditioning chamber to test the effects of operant conditioning principles on rats, cats and other species. From this experiment, he discovered that the rats learned very effectively if they were rewarded frequently with food. Skinner also found that he could shape (create new behavior) the rats' behavior through the use of rewards, which could, in turn, be applied to human learning as well.
Skinner's model was based on the premise that reinforcement is used for the desired actions or responses while punishment was used to stop the responses of the undesired actions that are not. This theory proved that humans or animals will repeat any action that leads to a positive outcome, and avoid any action that leads to a negative outcome. The experiment with the pigeons showed that a positive outcome leads to learned behavior since the pigeon learned to peck the disc in return for the reward of food.
These historical consequential contingencies subsequently lead to (antecedent) stimulus control, but in contrast to respondent conditioning where antecedent stimuli elicit reflexive behavior, operant behavior is only emitted and therefore does not force its occurrence. It includes the following controlling stimuli:
Watson's "Behaviorist Manifesto" has three aspects that deserve special recognition: one is that psychology should be purely objective, with any interpretation of conscious experience being removed, thus leading to psychology as the "science of behavior"; the second one is that the goals of psychology should be to predict and control behavior (as opposed to describe and explain conscious mental states); the third one is that there is no notable distinction between human and non-human behavior. Following Darwin's theory of evolution, this would simply mean that human behavior is just a more complex version in respect to behavior displayed by other species.Richard Gross, Psychology: The Science of Mind and Behaviour
Behaviorist sentiments are not uncommon within philosophy of language and analytic philosophy. It is sometimes argued that Ludwig Wittgenstein defended a logical behaviorist position (e.g., the beetle in a box argument). In logical positivism (as held, e.g., by Rudolf Carnap and Carl Hempel), the meaning of psychological statements are their verification conditions, which consist of performed overt behavior. W. V. O. Quine made use of a type of behaviorism, influenced by some of Skinner's ideas, in his own work on language. Quine's work in semantics differed substantially from the empiricist semantics of Carnap which he attempted to create an alternative to, couching his semantic theory in references to physical objects rather than sensations. Gilbert Ryle defended a distinct strain of philosophical behaviorism, sketched in his book The Concept of Mind. Ryle's central claim was that instances of dualism frequently represented "", and hence that they were really misunderstandings of the use of ordinary language. Daniel Dennett likewise acknowledges himself to be a type of behaviorist, though he offers extensive criticism of radical behaviorism and refutes Skinner's rejection of the value of intentional idioms and the possibility of free will.
Molar behaviorists, such as Howard Rachlin, Richard Herrnstein, and William Baum, argue that behavior cannot be understood by focusing on events in the moment. That is, they argue that behavior is best understood as the ultimate product of an organism's history and that molecular behaviorists are committing a fallacy by inventing fictitious proximal causes for behavior. Molar behaviorists argue that standard molecular constructs, such as "associative strength", are better replaced by molar variables such as rate of reinforcement. Thus, a molar behaviorist would describe "loving someone" as a pattern of love over time; there is no isolated, proximal cause of loving behavior, only a history of behaviors (of which the current behavior might be an example) that can be summarized as "love".
Pavel et al. (2015) found that in the realm of Health care and health psychology, substantial evidence supports the notion that personalized health interventions yield greater effectiveness compared to standardized approaches. Additionally, researchers found that recent progress in sensor and communication technology, coupled with data analysis and computational modeling, holds significant potential in revolutionizing interventions aimed at changing health behavior. Simultaneous advancements in sensor and communication technology, alongside the field of data science, have now made it possible to comprehensively measure behaviors occurring in real-life settings. These two elements, when combined with advancements in computational modeling, have laid the groundwork for the emerging discipline known as behavioral informatics. Behavioral informatics represents a scientific and engineering domain encompassing behavior tracking, evaluation, computational modeling, deduction, and intervention.
In more recent years, several scholars have expressed reservations about the pragmatic tendencies of behaviorism.
In the early years of cognitive psychology, behaviorist critics held that the empiricism it pursued was incompatible with the concept of internal mental states. Cognitive neuroscience, however, continues to gather evidence of direct correlations between physiological brain activity and putative mental states, endorsing the basis for cognitive psychology.
The influential Rescorla-Wagner model highlights the significance of competition for limited "associative value," essential for assessing predictability. A similar formal argument was presented by Ying Zhang and John Staddon (1991, in press) concerning operant conditioning: the combination of contiguity and competition among action tendencies suffices as an assignment-of-credit mechanism capable of detecting genuine instrumental contingency between a response and its reinforcer. This mechanism delineates the limitations of Skinner's idea of adventitious reinforcement, revealing its efficacy only under stringent conditions – when the reinforcement's strengthening effect is nearly constant across instances and with very short intervals between reinforcers. However, these conditions rarely hold in reality: behavior following reinforcement tends to exhibit high variability, and superstitious behavior diminishes with extremely brief intervals between reinforcements.
Although ABA and behavior modification are similar behavior-change technologies in that the learning environment is modified through respondent and operant conditioning, behavior modification did not initially address the causes of the behavior (particularly, the environmental stimuli that occurred in the past), or investigate solutions that would otherwise prevent the behavior from reoccurring. As the evolution of ABA began to unfold in the mid-1980s, functional behavior assessments (FBAs) were developed to clarify the function of that behavior, so that it is accurately determined which differential reinforcement contingencies will be most effective and less likely for aversive to be administered. In addition, methodological behaviorism was the theory underpinning behavior modification since private events were not conceptualized during the 1970s and early 1980s, which contrasted from the radical behaviorism of behavior analysis. ABA—the term that replaced behavior modification—has emerged into a thriving field.
The independent development of behavior analysis outside the United States also continues to develop. In the US, the American Psychological Association (APA) features a subdivision for Behavior Analysis, titled APA Division 25: Behavior Analysis, which has been in existence since 1964, and the interests among behavior analysts today are wide-ranging, as indicated in a review of the 30 Special Interest Groups (SIGs) within the Association for Behavior Analysis International (ABAI). Such interests include everything from animal behavior and environmental conservation to classroom instruction (such as direct instruction and precision teaching), verbal behavior, developmental disabilities and autism, clinical psychology (i.e., Criminology), behavioral medicine (i.e., behavioral gerontology, AIDS prevention, and fitness training), and consumer behavior analysis.
The field of Animal training—a sub-discipline of ABA that involves training animals—is regulated by the Animal Behavior Society, and those who practice this technique are called applied animal behaviorists. Research on applied animal behavior has been frequently conducted in the Applied Animal Behaviour Science journal since its founding in 1974.
ABA has also been particularly well-established in the area of developmental disabilities since the 1960s, but it was not until the late 1980s that individuals diagnosed with autism spectrum disorders were beginning to grow so rapidly and groundbreaking research was being published that parent advocacy groups started demanding for services throughout the 1990s, which encouraged the formation of the Behavior Analyst Certification Board, a credentialing program that certifies professionally trained behavior analysts on the national level to deliver such services. Nevertheless, the certification is applicable to all human services related to the rather broad field of behavior analysis (other than the treatment for autism), and the ABAI currently has 14 accredited MA and Ph.D. programs for comprehensive study in that field.
Early behavioral interventions (EBIs) based on ABA are empirically validated for teaching children with autism and have been proven as such for over the past five decades. Since the late 1990s and throughout the twenty-first century, early ABA interventions have also been identified as the treatment of choice by the US Surgeon General, American Academy of Pediatrics, and US National Research Council.
Discrete trial training—also called early intensive behavioral intervention—is the traditional EBI technique implemented for thirty to forty hours per week that instructs a child to sit in a chair, imitate fine and gross motor behaviors, as well as learn eye contact and speech, which are taught through shaping, modeling, and prompting, with such prompting being phased out as the child begins mastering each skill. When the child becomes more verbal from discrete trials, the table-based instructions are later discontinued, and another EBI procedure known as incidental teaching is introduced in the natural environment by having the child ask for desired items kept out of their direct access, as well as allowing the child to choose the play activities that will motivate them to engage with their facilitators before teaching the child how to interact with other children their own age.
A related term for incidental teaching, called pivotal response treatment (PRT), refers to EBI procedures that exclusively entail twenty-five hours per week of naturalistic teaching (without initially using discrete trials). Current research is showing that there is a wide array of learning styles and that is the children with receptive language delays who initially require discrete trials to acquire speech.
Organizational behavior management, which applies contingency management procedures to model and reinforce appropriate work behavior for employees in organizations, has developed a particularly strong following within ABA, as evidenced by the formation of the OBM Network and Journal of Organizational Behavior Management, which was rated the third-highest impact journal in applied psychology by ISI JOBM rating.
Modern-day clinical behavior analysis has also witnessed a massive resurgence in research, with the development of relational frame theory (RFT), which is described as an extension of verbal behavior and a "post-Skinnerian account of language and cognition."Hayes, S.C.; Barnes-Holmes, D. & Roche, B. (2001) Relational Frame Theory: A Post-Skinnerian account of human language and cognition. Kluwer Academic: New York. RFT also forms the empirical basis for acceptance and commitment therapy, a therapeutic approach to counseling often used to manage such conditions as anxiety and obesity that consists of acceptance and commitment, value-based living, cognitive defusion, counterconditioning (mindfulness), and contingency management (positive reinforcement).Corrigan, P. W. (2001). Getting ahead of the data: A Threat to some behavior therapies. The Behavior Therapist, 24(9), 189-193.[9]Hayes, S. C. (2002). On being visited by the vita police: A reply to Corrigan. The Behavior Therapist, 25, 134-137.[10]Corrigan, P. (2002). The data is still the thing: A reply to Gaynor and Hayes. The Behavior Therapist, 25, 140.[11]Powers, M.B., Vörding, M. & Emmelkamp, P.M.G. (2009). Acceptance and commitment therapy: A meta-analytic review. Psychotherapy and Psychosomatics, 8, 73-80.Levin, M., & Hayes, S.C. (2009). Is Acceptance and commitment therapy superior to established treatment comparisons? Psychotherapy & Psychosomatics, 78, 380.Powers, M. B., & Emmelkamp, P. M. G. (2009). Response to 'Is acceptance and commitment therapy superior to established treatment comparisons?' Psychotherapy & Psychosomatics, 78, 380–381. Another evidence-based counseling technique derived from RFT is the functional analytic psychotherapy known as behavioral activation that relies on the ACL model—awareness, courage, and love—to reinforce more positive moods for those struggling with depression.
Incentive-based contingency management (CM) is the standard of care for adults with substance-use disorders; it has also been shown to be highly effective for other addictions (i.e., obesity and gambling). Although it does not directly address the underlying causes of behavior, incentive-based CM is highly behavior analytic as it targets the function of the client's motivational behavior by relying on a preference assessment, which is an assessment procedure that allows the individual to select the preferred reinforcer (in this case, the monetary value of the voucher, or the use of other incentives, such as prizes). Another evidence-based CM intervention for substance abuse is community reinforcement approach and family training that uses FBAs and counterconditioning techniques—such as behavioral skills training and relapse prevention—to model and reinforce healthier lifestyle choices which promote self-management of abstinence from drugs, alcohol, or cigarette smoking during high-risk exposure when engaging with family members, friends, and co-workers.
While schoolwide positive behavior support consists of conducting assessments and a task analysis plan to differentially reinforce curricular supports that replace students' disruptive behavior in the classroom, pediatric feeding therapy incorporates a liquid chaser and chin feeder to shape proper eating behavior for children with feeding disorders. Habit reversal training, an approach firmly grounded in counterconditioning which uses contingency management procedures to reinforce alternative behavior, is currently the only empirically validated approach for managing tic disorders.
Some studies on exposure (desensitization) therapies—which refer to an array of interventions based on the respondent conditioning procedure known as habituation and typically infuses counterconditioning procedures, such as meditation and breathing exercises—have recently been published in behavior analytic journals since the 1990s, as most other research is conducted from a cognitive-behavior therapy framework. When based on a behavior analytic research standpoint, FBAs are implemented to precisely outline how to employ the flooding form of desensitization (also called direct exposure therapy) for those who are unsuccessful in overcoming their specific phobia through systematic desensitization (also known as graduated exposure therapy). These studies also reveal that systematic desensitization is more effective for children if used in conjunction with shaping, which is further termed contact desensitization, but this comparison has yet to be substantiated with adults.
Other widely published behavior analytic journals include Behavior Modification, The Behavior Analyst, Journal of Positive Behavior Interventions, Journal of Contextual Behavioral Science, The Analysis of Verbal Behavior, Behavior and Philosophy, Behavior and Social Issues, and The Psychological Record.
A popularly noted counseling intervention known as dialectical behavior therapy (DBT) includes the use of a chain analysis, as well as cognitive restructuring, emotional regulation, distress tolerance, counterconditioning (mindfulness), and contingency management (positive reinforcement). DBT is quite similar to acceptance and commitment therapy, but contrasts in that it derives from a CBT framework. Although DBT is most widely researched for and empirically validated to reduce the risk of suicide in psychiatric patients with borderline personality disorder, it can often be applied effectively to other mental health conditions, such as substance abuse, as well as mood and eating disorders. A study on BPD was conducted, confirming DBT as a constructive therapeutic option for emotionally unregulated patients. Before DBT, participants with borderline personality disorder were shown images of highly emotional people and neuron activity in the amygdala was recorded via fMRI; after 1 year of consistent dialectical behavior therapy, participants were re-tested, with fMRI capturing a decrease in amygdala hyperactivity (emotional activation) in response to the applied stimulus, exhibiting increases in emotional regulation capabilities.
Most research on exposure therapies (also called desensitization)—ranging from eye movement desensitization and reprocessing therapy to exposure and response prevention—are conducted through a CBT framework in non-behavior analytic journals, and these enhanced exposure therapies are well-established in the research literature for treating phobic, post-traumatic stress, and other anxiety disorders (such as obsessive-compulsive disorder, or OCD).
Cognitive-based behavioral activation (BA)—the psychotherapeutic approach used for depression—is shown to be highly effective and is widely used in clinical practice. Some large randomized control trials have indicated that cognitive-based BA is as beneficial as antidepressant medications but more efficacious than traditional cognitive therapy. Other commonly used clinical treatments derived from behavioral learning principles that are often implemented through a CBT model include community reinforcement approach and family training, and habit reversal training for substance abuse and tics, respectively.
