TABORDA, Catalina Gaviria; GAVIRIA, Ana M.; LOPERA, Francisco  e  MONTOYA-ARENAS, David-Andrés. Differences in working memory performance between men and women aged 49 and over in Medellin, Antioquia. Acta Neurol Colomb. [online]. 2019, vol.35, n.2, pp.55-63. ISSN 0120-8748.


the objective of this study was to evaluate working memory performance in a population aged 50 and over from Medellin, analyzing the differences of this achievement between men and women.


An analytical observational study was carried out with a cross-sectional design in which the performance of this system was evaluated in 144 subjects with the Digit Span and the Corsi Block-Tapping Task. Participants were 60 men (41.7 %) and 84 women (58.3 %) with an average age of 66.5 ± 9.9 and 69.3 ± 12.1 years, respectively.


Results show that men's scores slightly surpass those of women in all the tests performed, with a statistically significant difference in the Corsi Block-Tapping Task. Furthermore, women have a better performance in simple span tasks and verbal tasks, while men achieve better results in complex span tasks and visuospatial tasks.


These findings suggest that men have an advantage over women in attentional control, and they have a better capacity to maintain and integrate visual and kinesthetic information. Also, these results indicate that men have a better development in some higher-order cognitive skills as language comprehension and visuospatial orientation.
