A Mokken Scale for Transitive Reasoning Suited for Longitudinal Research
Anton C. Verweij · International Journal of Behavioral Development · 1996
A set of transitivity tasks was solved on two occasions by 634 2nd through 6th grade primary school children. Transitivity scales were constructed for both occasions using M okken scale analysis. Combining the results, one final scale was constructed for use in future research. The order of the scale tasks according to their difficulty level was the sam e on both occasions. A nalysis of the scale scores of one group retested after 16 weeks and two control groups revealed an absence of effects due to mem orisation or test experience. It was concluded that the final scale is useful as a transitivity measure in longitudinal research.
