Cognitive Processes on Achievement Tests: Intra-Person Differences in Item Response Times Correlations

• In Event: Response Times

Abstract

Several item response theory (IRT) models incorporate response times (RT) to increase interpretability and precision of trait level scores. If examinees differ in strategies for using RT, the joint model assumptions may not be plausible. In the current study, mathematical achievement tests are examined for within-examinee differences in RT relationships.
