Resumen

La memoria espacial se considera un factor selectivo en la evolución de la inteligencia. Los estudios en animales permiten pensar que los procesos cognitivos descriptos en humanos comparten características con los de otras especies. Se estudió el comportamiento espacial vinculado a la búsqueda del alimento de los monos capuchinos y su capacidad de retener información sobre la ubicación y estado del mismo. Durante los seguimientos de tres grupos de Cebus nigritus silvestres se aplicó un diseño observacional cualitativo que evaluó las cantidades de fruta madura e inmadura presentes en los árboles frutales consumidos por los monos en sus desplazamientos diarios. Las visitas a los árboles de frutos indicaron que los monos retienen información particular sobre la ubicación y condición de cada árbol. Los resultados obtenidos son fundamentales para la comprensión del funcionamiento de los mecanismos cognitivos no mediados por el lenguaje, lo cual permite ampliar los conocimientos de la base biológica del comportamiento espacial no humano.

Spatial memory is considered a selective factor in the evolution of intelligence. Animal studies lead us to believe that cognitive processes described in humans may have much in common with those of other species. We studied the foraging spatial behavior of capuchin monkeys and their ability to retain information about food location and quality. We analyzed whether individuals were able to integrate stored information about food sites and changes in the ripening of the resource. A qualitative observational design was used to monitor three groups of wild Cebus nigritus in their daily movements, evaluating the amounts of ripe and unripe fruit present in the fruiting trees consumed by monkeys. Visits to fruiting trees showed that monkeys remember specific information on the location and condition of each tree. These findings are essential to understand cognitive mechanisms not mediated by language, allowing a more comprehensive analysis of the biological basis of non-human spatial behavior.
