The organization of personality consists of interpersonal events and interpersonal behavior.

Sullivan’s Theory focuses on: 1-Personality as hypothetical entity 2- This personality is a part of an interpersonal situation and interpersonal behavior.

Harry Stack Sullivan: Biographical sketch

Harry Stack Sullivan was born in 1892 in Norwich, near New York and died in1949 in Paris. He received his medical degree in 1917 and served with the armed forces in World War I. In 1922 he met William Alanson White, a leader in American Neuropsychiatry. Then he conducted investigations in Schizophrenia that established his reputation as a clinician. Harry Stack Sullivan was the creator of a new viewpoint that is known as the interpersonal theory of Psychiatry. Its major tenet as it relates to personality is “the relatively enduring pattern of recurrent interpersonal situations which characterize a human life”.. Personality is a hypothetical entity that cannot be isolated from interpersonal situations, and interpersonal behavior is all that can be observed as personality Sullivan sees the individual as the object of study because the individual does not and cannot exist apart from his or her relations with other people. From the first day of life, the baby is a part of an interpersonal situation, and throughout the rest of its life it remains a member of a social field. Even a wild cat who has resigned from society carries with him into the wilderness memories of former personal relationships that continue to influence his thinking and acting.

Sullivan does not deny the importance of heredity and maturation in shaping the organism; he feels that human is the product of social interactions. More over, the interpersonal experiences of a person may alter his or her purely physiological functioning, so that even the organism loses its status as a biological entity and becomes a social organism with its own socialized ways of breathing, digesting, eliminating, circulating, and so forth.

For Sullivan, the science of psychiatry is allied with social psychology, and his theory of personality bears the imprint of his strong preference for social psychological concepts and variables.

Sullivan insists repeatedly that personality is a purely hypothetical entity, “an illusion,” which cannot be observed apart from interpersonal situations. The unit of study is the interpersonal situation and not the person. The organization of personality consists of interpersonal events rather than intra-psychic ones. Personality only manifests itself when the person is behaving in relation to one or more other individuals. These people do not need to be present; in fact they can even be illusory or nonexistent figures.

Dynamism is the smallest unit that can be employed in the study of the individual. It is defined as “the relatively enduring pattern of energy transformations, which recurrently characterize the organism in its duration as a living organism” An energy transformation is any form of behavior. It may be overt and public like talking, or covert and private like thinking and fantasying.

Because dynamism is a pattern of behavior that endures and recurs, it is about the same thing as a habit. This means that a new feature may be added to a pattern without changing the pattern just as long as it is not significantly different from the other contents of the envelope. It is significantly different it changes the pattern into a new pattern. For example, two apples may be quite different in appearance and yet be identified as apples because their differences are not important. However, an apple and a banana are different in significant respects and consequently form two different patterns.

1-The Self-System

Anxiety is a product of interpersonal relations, being transmitted originally from the mother to the infant and later in life by threats to one’s security. To avoid or minimize actual or potential anxiety, people adopt various types of protective measures and supervisory controls over their behavior. One learns, for example, that one can avoid punishment by conforming to parents’ wishes. These security measures form the self-system that sanctions certain forms of behavior (the good-me self) and forbids other forms (the bad-me self).

The self-system as the guardian of one’s security tends to become isolated from the rest of the personality; it excludes information that is incongruous with its present organization and fails thereby to profit from experience. Since the self guards the person from anxiety, it is held in high esteem and is protected from criticism. As the self-system grows in complexity and independence, it prevents the person from making objective judgments of his or her own behavior and it glosses over obvious contradictions between what the person really is and what the self-system says he or she is. In general, the more experiences people have with anxiety, the more inflated their self-system becomes and the more it becomes dissociated from the rest of the personality. Although the self-system serves the useful purpose of reducing anxiety, it interferes with one’s ability to live constructively with others.


A personification is an image that an individual has of him or herself or of another person. It is a complex of feelings, attitudes, and conceptions that grows out of experiences with need-satisfaction and anxiety.

For example, the baby develops a personification of a good mother by being nursed and cared for by her. Any interpersonal relationship that involves satisfaction tends to build up a favorable picture of the satisfying agent. On the other hand, the baby’s personification of a bad mother results from experiences with her that evokes anxiety. The anxious mother becomes personified as the bad mother. Ultimately, these two personifications of the mother along with any others that may be formed, such as the overprotective mother, fuse together to form a complex personification.

3-Cognitive Process

Sullivan’s unique contribution regarding the place of cognition in the affairs of personality is his threefold classification of experience. Experience, he says, occurs in three modes; these are Prototaxic


Syntaxic 1-Prototaxic experience “may be regarded as the discrete series of momentary states of the sensitive organism”. This type of experience is similar to the “stream of consciousness,” the raw sensations, images, and feelings that flow through the mind of a sensate being. They have no necessary connection” among themselves and possess no meaning for the experiencing person.


The prototaxic mode of experience is found in its purest form during the early months of life and is the necessary precondition for the appearance of the other two modes.

2-The Parataxic mode of thinking consists of seeing causal relationship between events that occur at about the same time but which are not logically related. When ever a black cat comes my way I face disaster, we see causal connections between experiences that have nothing to do with one another.
