FERNANDES, Débora Cecilio; RUEDA, Fabián Javier Marín  and  SISTO, Fermino Fernandes. Age and intelligence: related variables?. Aval. psicol. [online]. 2009, vol.8, n.3, pp. 303-311. ISSN 1677-0471.

This study aimed to investigate the relationship between the performance in the Test RIn, which measures fluid intelligence (g factor), and the age variable. The test was administered to 1102 participants, with mean age of 18,99 years (SD=6,06), from the states of São Paulo and Minas Gerais. The first analysis of variance showed no correlation between the variables, so the participants were divided into two groups of age, one of them until the age of 22 and the other one 23 years old and up. The subsequent analysis showed that there was a positive correlation between the group of age until 22 years old and the scores of the test, which indicates that as increased the age, the scores also increased. In contrast, the age group from 23 years old and up negatively correlated with the scores of the test, suggesting that the fluid intelligence is ending its development and the beginning of a mild diminishing. Furthermore, it was found significant differences among five age groups scores,: ranging from 11 to 13, 14 to 16, 17 to 22, 23 to 32, 33 to 49 and lastly from 50 years old.
