Studies have shown an increase in intelligence test scores across decades - the "Flynn effect". Nevertheless, the fact that this effect has not been consistently observed when different sources of cognitive ability are used is one of the main topics of discussion. Thus, the present research aimed to shed some light on this issue. Two studies using different cognitive ability measures were designed in order to control for potential measure effects. Children were Brazilian, aged between 6-12 years. The first study had the Draw-a-Person test as a measure of intelligence; 294 children were assessed during 1980 decade, whilst 203 were assessed during the 2000 decade. The second study used the Raven's Coloured Progressive Matrices. A total of 562 children were assessed during 1990 decade, and 243 in 2000 decade. Results showed no significant generation effects regardless of the measure used. Educational and social aspects are considered in order to explain these results.
