Abstract
TABORDA, Catalina Gaviria; GAVIRIA, Ana M.; LOPERA, Francisco and 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. https://doi.org/10.22379/24224022235.
INTRODUCTION:
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.
MATERIALS AND METHOD:
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:
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.
CONCLUSION:
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.
