Psychological Institute RAE, Moscow
This review examines the approaches to investigation and interpretation of cross-cultural differences in intelligence. Cross-cultural differences in measured intelligence have been observed in many studies. The paper discusses the mechanisms of cross-cultural differences. Particular attention is paid to the analysis of cross-cultural twin studies. An analysis of twin studies in different countries showed considerable variation in estimates of heritability of intelligence that shows usefulness of cross-cultural genetically informative studies in understanding the nature of intelligence.
Keywords: intelligence, cognitive abilities, cross-cultural studies, twins, culture, heritability, environment.
