A Commentary on: On the Importance of the Speed-Ability Trade-Off When Dealing With Not Reached Items by Tijmstra, J., and Bolsinova M. (2018). Front. Psychol. 9:964. doi: 10.3389/fpsyg.2018.00964
In their 2018 article, (T&B) discuss how to deal with not reached items due to low working speed in ability tests (Tijmstra and Bolsinova, 2018). An important contribution of the paper is focusing on the question of how to define the targeted ability measure. In this note, we aim to add further aspects to this discussion and to propose alternative approaches.
