Associations Between Individual And Contextual Factors With Cognitive Performance In Preschoolers From Unsatisfied Basic Needs (Ubn) Homes

In the context of an experimental intervention aimed at optimizing cognitive development through play activities for mothers and their children, this study presents the results of an association analysis between (a) individual (i.e. cortisol, electroencephalographic activity, language, and health conditions), and (b) contextual factors (i.e. home characteristics, maternal health, and mother language) with the efficiency in task solution with cognitive demands, in a sample of 46 5-years-old children, with no history of developmental disorder, and from UBN homes. After applying non-parametric trend analyses between groups, the results indicated the following as the factors of greatest association with cognitive performance: (a) neural connectivity and power; and (b) mother language. The implemented approach contributes to the understanding of the associations between individual and contextual factors of cognitive performance, considering different levels of organization involved in its development.
