This article aims to show the final results of the research project devoted to build norms for Raven’s Standard Progressive Matrices (Raven, Raven, & Court, 2003), on subjects aged 19 to 30 years old in the city of La Plata, Argentina. The sample consisted of 979 subjects of both sexes, and was divided into four age groups. The results show that as the participant’s age increases, the average group’s performance improves, and variability remains similar between groups. There were no statistically significant differences found between sexes, or between the current results and those from the 2000 norms. It was found that the scores’ increase, expected according to the Flynn effect, has stopped, and the possible intergenerational cognitive differences which could explain this phenomenon are discussed. These results are also compared with those from recent research made in other countries.
