"If something exists, it exists in some quantity, and it it exists in some quantity, it can be measured." - Edward Lee Thorndike
Objectives:
* Discuss the nature of personality assessment * Discuss whether personality tests provide S or B data * Discuss projective and and objective tests * Discuss the methods of objective test construction * Discuss the purpose and potential problems of personality testing
The Nature of Personality Assessment
* More than just measuring traits. * Personality: characteristic patters of behavior, thought, or emotional experience that exhibit relative consistency across time and situations * * Also measures motives, intentions, goals, strategies, and how people perceive and construct the world. * Not restricted to psychologists * * How did you decide whom to have as a roommate? * How did you decide which free-time activities to do? * More important than those made by psychologists * Most important to know: degree to which the judgment or test is right or wrong * * Test: validity * Judgment: accuracy * Two basic criteria * * Agreement * Prediction
Personality Test
* Used by psychologists (experimental and clinical), corporations, and the military * Omnibus inventories: measures a wide range of traits * Some tests are designed to measure one trait * Most tests provide S data * Some test provide B data * * Minnesota Multiphasic Personality Inventory (MMPI) * Implicit Association Tests (IAT) * * Theory: people who implicitly, or nonconsciously, know they have a certain trait will respond faster when the trait is paired with “me” (i.eere better predicted by the IAT. shy) * Aspects of shyness that participants consciously controlled could be predicted by “S” data scores.
