The main concepts of the behaviorist perspective theory
The main models of the deportmentist sentiment theoryAs a reaction to the introspective analysis regularity in psychological science and the focus on the national of amiable processes, apprised or unconscious(p) that dominated the beginning of the last century and was considered the endeavor of psychology at that time1, a new draw close was authentic under the name of expressionistic psychology. This new psycho healing(p) approach was to dominate psychology for about 50 years. Precursors of this approach be the Ameri toilet psychologist Edward Lee Thorndike2and the Russian psychologist Ivan Pavlov3, just now the genius who is considered the father of behaviorism and established its supposititious and functional fundaments is John Watson4. Behavior becomes the focus of psychological investigation beca role it is the however wholeness that can be scientific al angiotensin-converting enzymey studied and quantified, predicted and comptrollerled.The behaviourist as sumptions be that psychology should be seen as a science and therefore it should deal with plain behaviors that generate empirical data the milieu plays a decisive social function in de marchesining behavior as opposed to the psychic intragroup processes all behavior is apprehendt from purlieu and this learning process is ex agitateable to animals. In contrast with the vague concepts used by introspectionism, behaviorism places a advanced emphasis on the use of operational definitions that is defining various concepts in terms of observable events that may be used to describe compassionate experience in terms of stimuli and chemical reactions. A specific characteristic of behaviorism is parsimony seeking the simplest possible explanation for any event5. recognise concepts of behaviorism comprise the stimulus response (S-R) equation, the classical and operant t each(prenominal), and the livelihood and punishment nonions. The order used to analyze behavior is the l ab try which gave the possibility to manipulate the independent variable in order to playing area the dependent variable. stimulant drug is a measurable transport in the environment any object, position, event or situation that may crap an jounce on behavior, bandage response is a measurable change in behavior any reaction to a stimulus either environmental or mental. The behaviouristic theory excludes thoughts, feelings and other mental occurrences, and genetic factors as healthful, that is everything that cannot be study objectively, in observable terms.Watson took further Pavlovs idea of conditioning6and applied it to humans. According to him humans are born tabula rasa and the behavior is hardly learnt from the environment through a process of conditioning. In a storied and controversial experiment because of its ethical implications, Watson and Rayner (1920) learn Little Albert an 18-months old yearling to develop a fear response to rats, by associating the rat NS with a strong noise UCS. They conducted their research following the classical conditioning project Noise (UCS) apprehension (UCR) Noise (UCS) + Rat (NS) Anxiety (UCR) Rat (CS) Anxiety (CR)7.Close related to the process of classical conditioning is the generalization that occurs. Thus, stimuli resembling to the original CS would tend to elicit the same CR. In the occurrence of Little Albert it was reported that the boy was showing strong signs of dread to all fluffy objects, which were similar to the white rat used in experiment. Stimulus generalization terminations in opposeing to a whole class of related stimuli, by and by initial learning with a single stimulus and can enable organisms to adapt better to their environment though it may not unendingly be adaptive8. Behaviorists draw the conclusion that generalization is the first response of an organism when encountering new situations. Sometimes this generalization may progress to the spurt of stereotyping t hat occurs when generalizing based on group membership. To fight this phenomenon, behaviorists undertook and exemplified through research the concept of stimulus discrimination9, according to which an organism may be prepare to discriminate amongst two or more stimuli that progressively attach in alikeness. As Glassman and Haddad occlusion out stimulus discrimination always requires training in the absence of such(prenominal)(prenominal) training, organisms tend to generalize (emphasis theirs)10. hostile to the concept of conditioning is the concept of experimental extinction which suggests that what can be versed can overly be unl realize, and that a conditional response is not necessarily permanent11. However, as near research indicate12, extinction is likely to appear in humans in some elementary behaviors involving muscle responses like withdrawing from a hot surface, tho not in complex behaviors which subscribe to fear responses or other responses of the automati c neuronic system and which are very hard to extinguish. Using Pavlovs extinction procedure, Watson and Rayner attempt to eliminate the conditioned fear response associated with rats in Little Alberts carapace by perplexing the rat for a period of one-third weeks without associating it with the gongs noise. Contrary to their mentality the fear did not extinguish. Stimulus generalization and discrimination concepts as strongspring as the extinction principle stick a great splendour for our discussion because they pass on be used in the process of maturation behavioural cathartic techniques.Skupcountry developed the concept of operant conditioning. He argues that all behavior is modeled by complex reinforcement patterns from the environment. In his view, humans and animals actively engage with their environment, as opposed to the Watsonian emphasis on classical conditioning where they are more passive waiting for the environment to produce stimuli to which they may respond to. Skinners main idea is that human behavior is determined by the consequences of its sometime(prenominal) behavior. If from a Watsonian perspective the behavior is triggered by external stimuli, get-go with Skinner the behavior may be fire by internal stimuli as hearty, as a issuance of then(prenominal) internalized experiences. Thus operant conditioning is a type of learning where future day behavior is determined by the consequences of past behavior.According to Skinner the past behavior may influence feature behavior depending on three types of consequences if it had no consequence, the probability of that behavior to occur in the future is sterilize if the consequence is found pleasant, then the behavior is likely to be perennial in the future this was called positive reinforcement if the consequence is negative, then it acts as a punishment and makes that specific behavior unlikely to appear in the future. By extrapolation, learning occurs through manipulation of p ositive reinforcements and punishments. Newer behaviorist approaches hump that although the two types of conditioning reflex and operant were developed independent of each other by polar researchers, they are interconnected and in true(a) life situations both processes can occur simultaneously13.Practice therapeutic process and modesThe behavior therapeutic approach emerged from these behavioral principles of classical and operant conditioning. All behavior is learnt and therefore abnormal behavior is seen as the result of improper learning. In order to cure the individual needs to learn the correct behavior. The behavioral therapy applying the principle of here and now focuses on the stage behavior which the patient of role finds problematic as opposed to the psychodynamic therapy that focuses on identifying and bring out unconscious conflicts from childhood. The healer sees the patient as standing at the converging among genetic inheritance and learning that occurred through interaction between individual and environmental stimuli. These result in maladaptive thoughts, feelings, attitudes and verbal behavior.Conventionally, the psychotherapeutic process starts by behavior analysis14. The focus is on indentifying the flowing stimulus response relationship. Based on the disruptive behaviors identified the therapist designs a program (the psychotherapeutic process) meant to help the patient unlearn the faulty responses and if appropriate learn more adaptive behaviors. The patient is explained how the psychotherapy works, how the conditioned responses were learnt somewhere in the past and how the very same behavioral responses can be modified victimisation the techniques of behavioral therapy.According to Bennet, behavior therapy differs from psychoanalytic therapies in the following estimates it is directive, the therapist actively involves in the therapeutic process, using methods based on learning principles the goal of therapy is differen t in that it intends to change behavior not to reconstruct personality the therapy is shorter than other forms the interventions are indication specific, closer to the medical model of intervention rather than the psychoanalytic purgation or insight15.Behavioral techniques emerged from the classical conditioning principle involve systematic desensitisation, aversion therapy, implosion therapy and flooding. Operant conditioning techniques are related to what is comm wholly known in therapy as behavior qualifying, behavior shaping and image economy. Systematic desensitization is the treatment of choice for phobias and various anxiety induce behaviors. It aims at replacing the patients anxiety response with a relaxation one, by increasingly exposing the patient to a hierarchy of stimuli from the less anxiety evoking to the anxiety evoking stimulus itself. During the process, the patient goes to the next stage of the stimulus hierarchy only after succeeding to be fully relaxed i n the present of the introductory stimulus. This method requires the training of the patient in relaxation techniques16and involves the use of imagination, since when is impossible to be confronted with the actual situation (like is the case in social phobias) the patient has to imagine macrocosmness in those situations, following that life itself will supply opportunities to see if the therapy is successful or not. So, the exposure can be through in vitro or in vivo, depending on the phobic stimulus. However, studies have forceful that the important factor in curing is the exposure to the feared object or situation by breaking the negateance cycle created and reinforced in any phobia.Aversion therapy is used to induce an aversive response to stimuli which are associated with existing undesirable behaviors. It has been used in trying to treat hard addiction, by associating a nausea producing drug or a scummy electric shock with the un desire behavior of drinking. As a resu lt of this stimuli association, the patient is provoked to vomit. This supposedly might determine the patient avoid drinking in the future. However, this method raises serious ethical and effectiveness problems, the place of relapse organism reportedly very high.Implosion therapy and flooding involve that the patient has to face the worst possible fear producing situation, in imagination only in the former and in the physical context in the latter. In contrast with systematic desensitization which presupposes a gradual exposure to the stimuli, these techniques are more basis and less time consuming. If successful, the patient might be cured of a phobia in one hour. The advantage of this method is that the patient learns that there are no objective bases for his/her fear by accepting to openly confront it. Ethical problems are associated as well in regard to suffering from therapy.Derived from operant conditioning, the behavior modification method is largely used in educational an d clinical psychology contexts. It reinforces desired behaviors and ignores or punishes undesired ones. This techniques raises problems in choosing reinforcers since people can potentially respond to a wide range of such stimuli. Similar to behavior modification is the behavior shaping technique successfully used in operative with autistic children in order to maintain a desired behavior. some other operant application has been used in institutions (for examples schools and hospitals) within the programs called token economies, where conditioned reinforcers are offered to strengthen specific behaviors. Tokens are offered in exchange of a desired behavior and can later be transformed in something that the individual wants. Token behave as a secondary reinforcement for the primary reinforcements which are in fact desired. It may be also used to extinguish undesired behaviors by taking away the earned tokens to punish undesired behavior. Taken economies are uncommon and inefficient i n treating mental disorders, although they might contribute to alleviating some disruptive behaviors associated with mental disorders, such as aggressiveness, inadequate social interaction and use of bad speech communication17.Evaluation of the approach strengths and limitsOne of the major strengths of this approach is questionably considered its scientific background. Developed from lab experiments on animals (Pavlov-dogs, Thorndike cats, Watson rats, Skinner pigeons and rats) it focuses exclusively on behavior which can be observed and objectively measured. The behaviorist human being is concrete, realistic, determined in its actions by the environment and the society that he/she lives in. This theoretical approach proved to be productive in creating psychotherapeutic methods, chiefly successful in the area of phobias and addictions. Compared to other approaches behaviorism is supported by many experiments.However, there are discrepancies between the empirical and the theor etical developments in behaviorism, which is considered a limitation of the approach. Initial empirical studies were made on animals (as mentioned above) while the theoretical studies are done by generalizing observations made on animals upon humans. This fact cumulated with the declared behaviorists rejection of the importance of mental processes offers a very fragmented and simplistic view of human being. Watson believed that observing and describing behavior is enough to predict and control it. Thus, he eliminated explanation from psychology. Psychic life was acknowledged but its intellect was not considered necessary because it will finally manifest itself at behavioral level.At this point we need to reconsider what meaning we give to the term scientific, in regard to our double perspective taken by the present work. If scientific means that positive methods in studying human being (similar to the study of rocks, animals, meteorological phenomena etc.) are favored, then we migh t as well consider this psychological approach a step forward on the terrain of positive science. But if scientific means to conceptualize the human being in all its wholeness in order to understand its starting point, its inner resorts and teleological direction, then behaviorism might be seen as an unacceptable lessening of the complexity and mystery of human being.The intense use of lab experiments present the disadvantage of a low ecological boldness18. In time it became obvious that appreciation of behavior cannot come from the laboratory. On the other hand behaviorism was criticized as being reductionist by eliminating the meditational processes and too deterministic by the fact that human being is presented as not possessing free will. Another weakness identified by ethnological studies show that the principles of conditioning are not as universal as was once asserted19. However, maybe the most informed criticism is provided from within, by a behavior therapist like Lazarus connected with Joseph Wolpe, who states in regard to behavior therapy that the methods of behavior therapy are extremely effective when applied to carefully selected cases by informed practitioners. But when procedures overstep the boundaries of their legitimate terrain, ridicule and derogation are most likely to ensue. Far from being a panacea, the methods are then held to have no merit whatsoever, and the proverbial baby gets thrown and twisted out with the bath water The danger lies in a wrong elevation of learning principles into unwarranted scientific truths20.Comparison with psychodynamic perspective at bottom the behaviorist approach various theorists hold positions that may vary in some degrees but fundamentally assert the same thing behavior is the new found object of psychology this allows psychology to behave and to be considered a natural science a belief that its legitimate to study the animal behavior and compare it with human behavior the emphasis on environment a s causation of behavior and consequently dismiss mental processes.The psychodynamic and behaviorist perspectives on human being are opposed. They started from very different points in defining what human being is. Furthermore, the behaviorism appeared as a reaction to psychoanalysis and other currents in psychology that used the method of introspection to define and explain the inner, immaterial and unseen mental processes. Their approach was considered by behaviorists as mysticism. The focus in psychodynamic theories and practice is on inner processes that are seen as motivating and influencing behavior, while the focus in behaviorist theories and practice is on the outer world, i.e. environment that is seen as determining behavior. The change in psychoanalysis comes by uncovering unconscious conflicts that are the implicit in(p) causes of behavior, while the change in behaviorism comes by manipulating the environment in order to remove undesirable behavior. These opposing perspec tives do not completely eliminate dialogue since the unification point is the human being itself. For example, if a Freudian theorist suggests that adult behavior can best be understood by looking at childhood experiences, Skinner agrees but suggests that the connections are based on the reinforcement history of the person, not some vague concept of conflicts between id and ego21. In the Freudian understanding of human temperament, the person is born with instincts, hence the development of the drive and unconscious psychology, as opposed to the Watsonian perspective where humans are born tabula rasa. The behaviorist theorist Skinner describes the inner life as a low box. He acknowledges its existence but he sees it in behaviorist terms. For him the underground inner life is also behavior22. However, in the view of the major differences presented above we are enabled to draw the conclusion that psychoanalysis and behaviorism have as a starting point different assumptions concern ing human nature and therefore, develop at the conceptual- theoretical and practical-therapeutic level towards two distinct finalities. This point is very well made clear by Watson in one of his famous quotes Give me a dozen healthy infants, well-formed, and my own condition world to bring them up in and Ill guarantee to take anyone at random and train him to become any type of medical specialist I might select doctor, lawyer, artist, merchant -chief and yes, even beggar-man and thief, regardless of his talents, penchants, tendencies, abilities, vocations, and black market of his ancestors. I am going beyond my facts and I admit it, but so have the advocates of the contrary and they have been doing it for thousands of years23.Contributions to new developments notwithstanding all its limitations, the behaviorist approach has some positive points as well provided psychology with new and quantifiable concepts, opened the gate to new theories and explanations in psychology, crated m ore realistic methods. Somehow ironically, one of the major contributions made by behaviorism concerns the possibilities of research opened towards the investigation of cognitive processes that they initially rejected, which will fundament the new cognitive approach in psychology. For example, Edward Tolman, regarded as one of the founders of the cognitive approach, considered himself a behaviorist though not a radical behaviorist like Skinner. In addition, the study of many cognitive issues, such as observational learning imitation) and the use of hypotheses in problem solving, began with similar behaviorist studies of animals. Where the introspectionists failed in their attempts to make sense out of mental processes the behaviorists have pointed the way to new possibilities for a scientific psychology of the mind24.Neobehaviorism introduces the meditational processes (motive, emotion) between stimuli and response.
