Contemporary evidence shows that different intervention approaches can be effective in improving executive cognitive performance in preschoolers from poor homes. However, several aspects about the role of individual and contextual differences in intervention effects remain to be elucidated. The present study aimed to explore the impact of a computerized executive cognitive intervention with lab-based tasks in preschoolers from Unsatisfied Basic Needs (UBN) homes. In the context of a randomized controlled design, different activities were administered to children according to their baseline performance in a variety of cognitive tasks tapping inhibitory control, working memory, and planning demands (i.e., high- and low-performance intervention and control groups). Results suggested that the impact of the intervention was shown preferentially by high-performers in Tower of London and KBit tasks, who increased their performances in the posttest assessment. This finding supports the importance of considering individual and contextual differences in the design of interventions aimed at changing the cognitive performance of children from poor homes.
