Abstract
The purpose of the present study was to evaluate the psychometric properties of Raven’s colored progressive matrices by estimating the presence of pseudo-guessing and pseudo-carelessness. Participants were 1127 children from ages 5 to 11. Guessing and carelessness were assessed using the lower and upper asymptotes of the 3PL and 4PL item response theory (IRT) models, respectively. Optimal model fit was judged using difference loglikelihood tests and information criteria. Results indicated that guessing, but not carelessness, were evident in the AB and B forms of the CPM, with successful guessing being more prevalent in the AB form. It is concluded that nonverbal IQ estimation in CPM should include variable estimation methods so that aptitude scores are estimated with the highest possible accuracy.
Highlights
Optimal model fit was judged using difference loglikelihood tests and information criteria
The most important finding of the present study was that non-zero person parameters of guessing were observed with regard to Raven’s colored progressive matrices
When comparing nested models and penalizing the one estimating a larger number of parameters, the findings indicated a preference for the 4PL model
Summary
The purpose of the present study was to evaluate the psychometric properties of Raven’s colored progressive matrices by estimating the presence of pseudo-guessing and pseudo-carelessness. The children were told that the purpose of the study was to see how they think about geometric matching and that this ‘game’ would have no influence whatsoever on their school grades
