Mediating role of poverty in the association between environmental factors and cognitive performance in preschoolers

The association between environmental factors and cognitive performance during childhood could be mediated by poverty (i.e., households with Unsatisfied or Satisfied Basic Needs). This study explored such mediating roles in preschoolers from different socioeconomic backgrounds. Tasks to assess executive attention, working memory, inhibitory control, planning, and fluid reasoning were administered to 250 children aged 4 and 5 years. The results suggested that poverty mediated the effects of family composition, child health, health risk factors, children and adults at home, maternal age, and literacy activities on the performance of executive attention, fluid reasoning, and inhibitory control. These results contribute to our understanding of the relationship between environmental factors and cognitive development through the identification of the mediating role of poverty.
