Using Item Response Theory to Assess the Lynn-Flynn Effect Working Paper, Department of Educational Psychology, Baylor University, 2006 Cohort(s): Children of the NLSY79, NLSY79 Young Adult Publisher: Department of Educational Psychology, Baylor University Keyword(s): Flynn Effect; I.Q.; Intelligence Tests; Peabody Picture Vocabulary Test (PPVT); Test Scores/Test theory/IRT Permission to reprint the abstract has not been received from the publisher. The purpose of this manuscript is to demonstrate the use of Item Response Theory (IRT) methods in determining if the increase in mean IQ scores across time (i.e., the Lynn-Flynn Effect[LFE]) is due to an increase in intelligence, or if it is due to a psychometric artifact. This manuscript demonstrated the use of IRT in assessing the existence of the LFE using cohort data from both the Mathematics section of the College Basic Academic Subjects Examination (CBASE) and the Peabody Picture Vocabulary Test-Revised (PPVT-R) from the NLSY79 Children and Young Adults. |
