Influencia del nivel socioeconómico en el desarrollo de las competencias numéricas de los niños ecuatorianos de jardín infantil

The aim of this study was to examine the influence of the socioeconomic level of preschoolers on their development of early numerical skills and spontaneous focusing on numerosity (SFON), after controlling for domain-general cognitive variables like intelligence and working memory and for age. On entering preschool, 355 boys and girls were given a battery of tests to evaluate their early numerical skills, SFON, intelligence, and working memory. The results indicate that there are individual differences in early numerical skills and SFON among Ecuadorian children entering preschool. Also, socioeconomic level was positively correlated with early numerical skills, but not with SFON. At the end, we discuss the theoretical, methodological, and practical implications of the study.
