Personality Psych Lecture February 26, 2008 Validity Reading: -No single study or one source of data will ever sufficiently explain any important aspect of personality. -Psychological theory plays an essential role in developing an understanding of what any measure of personality really means. Criterion-oriented validation: investigator interested in some criterion which he wishes to predict. -Predictive Validity: criterion obtained after the test is given. -Concurrent Validity: test score and criterion score are determined at the same time. Studied when one test is proposed as a substitute for another or a test is shown to correlate with some contemporary criterion. -acceptance of a set of operations as an adequate definition of whatever is being measured, set standards. Ex. An employer does not care if a worker can manipulate blocks, but the score on the block test may predict something he cares about. -Content Validity: established by showing that the test items are a sample of a universe that the investigator is interested in. Established deductively, defining universe and sampling within to obtain a test. -when no criterion or universe of content is accepted as adequate to define the measured quality. -tester is concerned with the type of behavior involved in test performance. -Construct Validity: used whenever a test is to be interpreted as a measure of an attribute or quality which is not “operationally defined”. No standard procedure, based on investigator. -tester has no definite criterion measure of the quality with which he is concerned, uses indirect measures. (trait or quality is highest importance) Face Validity: refers to the extent of which you can tell what they are measuring just by looking at it. Ex. Depression tests (are you tired, irratible, non enthusasitc, sad? Etc) Objective tests – high face validity compared to projective tests. (an inkblot is projective and you have no idea what is being tested for) Incremental Validity: extent to which a test tells us something new that we didn’t know before. Ex. Woman’s husband dies. Decreased incremental validity, find out depressed. But tests reveal a woman is happy or relieved that her husband died so the incremental validity increases. A Theory of Human Motivation – Maslow Hierarchy of needs: lower physiological and safety needs must be satisfied before higher needs can emerge.

Humanistic: the study of human motivation does not need to be based on findings from research with animals, higher needs are uniquely human. -observed that a child that is satisfied in basic needs early in life becomes relatively tolerant of deprivation later in life, better able to focus on higher goals.
