A Speeded Item Response Model with Gradual Process Change
Goegebeur, Yuri; De Boeck, Paul; Wollack, James A.; Cohen, Allan S.
Psychometrika, v73 n1 p65-87 Mar 2008
An item response theory model for dealing with test speededness is proposed. The model consists of two random processes, a problem solving process and a random guessing process, with the random guessing gradually taking over from the problem solving process. The involved change point and change rate are considered random parameters in order to model examinee differences in both respects. The proposed model is evaluated on simulated data and in a case study.
