Variation in Raven's Progressive Matrices scores across time and place

Abstract: The paper describes a cross-cultural and historical meta-analysis of Raven''s Progressive Matrices. Data were analyzed of 798 samples from 45 countries (N =244,316), which were published between 1944 and 2003. Country-level indicators of educational permeation (which involves a broad set of interrelated educational input and output factors that are strongly related to economic development), the samples'' educational age, and publication year were all independently related to performance on Raven''s matrices. Our data suggest that the Flynn effect can be found in high as well as low GNP countries, although its size is moderated by education-related sample and country characteristics and seems to be smaller in developed than in emerging countries.
