PSYC3600 Lecture Notes - Shock Site, Convergent Validity, Criterion Validity
Document Summary
The four types of data are: self-report data (s-data) Common measures of attitude such as likert-type scales: observer- report data (o-data. Example: questionnaires and interviews that are completed by other people who know you: test-data (t-data) Example: observing the behavior of someone and some other response during certain situations: life-outcome data (l-data) Example: real-life observable outcome of possible psychological significance. To establish validity for a new trait you can uses different types of validity that draw inferences about personality from observations of behavior. This includes, construct validity, which is a test that measures broad categories such as face, convergent and discriminate validity. Face validity, which is test that is done and measures what its suppose to measure on the surface. Convergent validity is a test that correlates with other measures that should correlate with. Discriminant validity which does not correlate with another measure whose underlying construct is conceptually unrelated to it.
