Abstract

This study examined the utility of response timeā€based analyses in understanding the behavior of unmotivated test takers. For the data from an adaptive achievement test, patterns of observed rapidā€guessing behavior and item response accuracy were compared to the behavior expected under several types of models that have been proposed to represent unmotivated test taking behavior. Test taker behavior was found to be inconsistent with these models, with the exception of the effortā€moderated model. Effortā€moderated scoring was found to both yield scores that were more accurate than those found under traditional scoring, and exhibit improved person fit statistics. In addition, an effortā€guided adaptive test was proposed and shown by a simulation study to alleviate item difficulty mistargeting caused by unmotivated test taking.
