A researcher creates a new test for aggression levels. To assess the tests validity, its performance is compared to a previous test for aggression that has very high validity. Both tests are administered at about the same time; aggression levels are measured with the researcher's new test on one day, and on the next day, with the established test. What type of validity is being assessed here? A. Predictive Validity B. Concurrent Validity C. Face Validity D. Discriminent Validity
