- Comparison between unidimensional and multidimensional IRT models.
- Study of response times within computer-based adaptive tests.
The research activity is focused on latent variable models, and in particular Item Response Theory (IRT). In-depth analysis deals mainly with the comparison between unidimensional and multidimensional models in different possible situations. Recently, the study focused on coputer-based adaptive testing (CAT) and, specifically, response times in this area.
