Direct Observation
Have you ever watched the behavior of people as you waited in line or sat in a public place? If so, you were engaging in a process similar to the assessment known as direct observation. Psychologists sometimes look at the behavior of an individual as he/she interacts with others, carries on normal functions, or performs specific tasks in order to identify personality traits or problems. Behaviorists prefer observational techniques. They may use rating scales that list personality traits or behaviors to be evaluated. Behavioral assessments record the frequency of specific behaviors in an observation. Though they criticize the subjective nature of other types of assessment, behaviorists also have to make inferences about what they see in another person’s behavior. Lab studies have careful controls, but a potential flaw with naturalistic observational studies is the Hawthorn effect. When people know that they are being observed, they change their behavior to what they think the observer expects or to make themselves look good.
Projective Tests
Psychoanalysts use projective personality tests that present ambiguous stimuli, such as inkblots or pictures, with the assumption that test takers will project their unconscious thoughts or feelings onto the stimuli. The objective is to uncover deeply hidden unconscious thoughts, feelings, wishes, and needs. The famous Rorschach inkblot test presents 10 bilaterally symmetrical inkblots, asking the person to tell what he/she sees in each one and to indicate the features of the inkblot that prompted the response. The evaluator scores each response based on a rubric, inputs the data into a scoring system, then uses clinical judgment to prepare a profile of the person’s motives and conflicts. Another projective test, the Thematic Apperception Test (TAT) created by Henry Murray and Christiana Morgan, consists of a set of 20 cards (one blank) with people in ambiguous situations. People are shown a number of cards in sequence. Murray thought that people would reveal their need for achievement, sex, power, or affiliation in their answers to requests to tell what is happening in the picture, what led up to it, how the people feel, and how the situation turns out. For example, people who tell stories in which people work hard to accomplish their goals or overcome obstacles indicate a high need for achievement. Because they are unstructured, projective tests often get people to talk about anxiety-provoking situations that they otherwise wouldn’t reveal, exposing unconscious conflicts. Although psychoanalysts have delineated ways to interpret the subjective responses on projective tests, other psychologists question the validity and reliability of these assessments.
Self-Reported Tests
Self-report methods, the most common personality assessment techniques, involve the person answering a series of questions, such as a personality questionnaire, or supplying information about himself/herself. Different psychologists and different approaches make use of different self-report methods. Jung’s personality types are measured by the Myers-Briggs Type Indicator; Cattell’s personality traits are measured by the 16 PF; Rotter’s locus of control is measured by the Internal-External Locus of Control Scale; Maslow’s self-actualization is measured by the Personal Orientation Inventory; Rogers’s congruence between the actual self and ideal self is measured by the Q-sort. The validity of all of these is questioned. Among the best-known, most
