A reduced form of the CPM (A + AB): A useful tool for the assessment of children under six years of age

The progressive matrices of Raven (CPM) is a very useful test for clinicians. The CPM has three series (A, AB and B), with twelve items for each. In the present study, we showed that the B series is inappropriate for children below six years old. Therefore, we calculated norms for children between 3 and 6 years old in a reduced form of CPM (A + AB). Theoretical and practical implications are discussed. © 2015, Societa Editrice il Mulino.
