However, there are numerous theories, and they can be classified into three different categories: BiologicalLearning-basedPsychoanalytic It is unlikely that these three categories are mutually exclusive as chances are that multiple causes interact in individuals to cause phobias. For example, it may be that biological differences in the brain are triggered by an experience or something in that person's environment, or that a negative experience may lead to a learned response. Look at these theories and you'll see how complex the development of a phobia is, and why it likely stems from a combination of many factors. Psychoanalytic Theory Spazi Angusti/Getty Images Sigmund Freud is popularly known as the father of psychoanalysis. His pioneering structural theory was largely based on the three parts of the psyche: Ego Id Superego The id is the most primal and instinctive part of the mind and is the basis of our drives. The superego composes morals, values, and prohibitions internalized during development. The ego is the rational moderator between the two. A significant portion of the ego’s duty is to control the impulses of the id. According to this theory, phobias are based on anxiety reactions when the ego is overwhelmed by these forces. The phobia may symbolically represent some other internal source of anxiety. The Psychoanalytic Theory of Phobias Learning Theory Blend Images - JGI/Jamie Grill/Brand X Pictures/Getty Images The learning theory is a broadly inclusive set of theories that are based on principles of behaviorism and cognitive theory. Ivan Pavlov pioneered the learning theory by showing that dogs could be trained to salivate when a bell was rung. Since then, numerous psychologists have built on Pavlov’s work to develop more complex theories of human behavior. According to the learning theory, phobias develop when fear responses are reinforced or punished. Both reinforcement and punishment can be positive or negative. Positive reinforcement is the presentation of something positive, such as a parent rewarding a child for staying away from a snake. Positive punishment is the presentation of something negative or unfavorable to prevent that behavior from occurring again, such as a child being bitten by a snake. How Learning Theories Help Treat Phobias Biological Basis Catherine Delahaye/Getty Images The medical model of psychology states that mental disorders are caused by physiological factors. This theory focuses on neuropsychology, which is a branch of psychology that is dedicated to studying the structure and function of the brain. Neuropsychologists have identified certain genetic factors that may play a role in the development of phobias. It is also known that certain medications that affect the brain’s chemistry are helpful in treating phobias. Phobias With a Biological Cause A Word From Verywell At present, we have no definitive answer to what causes phobias. Chances are, however, that there are multiple causes, and that different people may develop phobias for different reasons. In some cases, a combination of genetic and physiological issues may be at play. For others, the cause may be psychological or environmental. Fortunately, exposure treatments are effective for phobias, regardless of their causes.
