Freud’s Psychoanalytic Theory

Conscious

Preconscious

Unconscious

Freud’s Psychoanalytic Theory

• Id- made up of innate, biological instincts and urges.

• Ego-responsible for planning, problem solving, reasoning, and controlling the potentially destructive energy of the id.

• Superego-a set of ethical rules for behavior.

Psychosexual Stages of Development

Freud vs. Erikson

Neo-Freudian Theories

• Alfred Adler-believed behavior is purposeful and goal-directed rather than motivated by unconscious forces.– Individual Psychology – we are motivated by our goals in

life—especially our goals of obtaining security and overcoming feelings of inferiority.

• Carl Jung-emphasized unconscious processes, but believed that the unconscious contains positive and spiritual motives as well as sexual and aggressive forces.– Two forms of unconscious: personal and collective

Neo-Freudian Theories

• Karen Horney- developed a creative blend of Freudian, Adlerian, and Jungian theory, with added concepts of her own.– Believed adult personality was shaped by the

child’s relationship to the parents—not by fixation at some stage of psychosexual development, as Freud argued.

Rogerian Theory

• Carl Rogers- coined the term self-concept (all the information and beliefs that individuals have about their own nature, qualities, and behavior).

• Unconditional Positive Regard- Roger’s term for positive behavior toward a person with no contingencies attached.

Maslow’s Theory

• Abraham Maslow believed that there is a basic goodness to human nature and a natural tendency toward self-actualization.

Bandura’s Theory of Reciprocal Determinism

• Self-efficacy- Bandura’s term for the learned belief that one is capable of producing desired results, such as mastering new skills and achieving personal goals.

• Reciprocal Determinism- cognitions, behaviors, and the environment interact to produce personality.

Rotter’s Theory of Locus of Control

• Julian Rotter suggests that learning experiences create cognitive expectancies that guide behavior and influence the environment.

• Considered locus of control in how people view their position in life.

Biopsychosocial Theory and Personality

Personality Tests

• Interviews and Observation• Objective Personality Tests- standardized

questionnaires that require written responses, usually to multiple choice or true-false questions.– Example: Minnesota Multiphasic Personality Inventory

(MMPI)• Projective Tests- psychological tests that use ambiguous

stimuli, such as inkblots or drawings, which allow the test taker to project his or her unconscious thoughts onto the test material.– Example: Rorschach Inkblot Test

Accuracy of Personality Assessment

• Deliberate Deception• Diagnostic Difficulties• Cultural Bias or Inappropriate Use• Reliability/Validity

Psychological Disorders

• Abnormal Behavior-patterns of emotion, thought, and action that are considered pathological (diseased or disordered) for one or more of these reasons: statistical infrequency, disability or dysfunction, personal distress, or violation of norms.

Birth of Psychiatry

“Mentally Ill”

• Thomas Szasz- a critic of the medical model—believes it encourages people to have no responsibility for their actions.

The Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR)
