ARAN FILIPPETTI, VANESSA. Executive functions in school-aged children: age and socioeconomic status effects. Av. Psicol. Latinoam. [online]. 2011, vol.29, n.1, pp.98-113. ISSN 1794-4724.

Lately, the study of prefrontal executive functions in grade scholars has noticeably increased. The aim of this study is to investigate the influence of age and socioeconomic status (SES) on executive tasks performance and to analyze those socioeconomic variables that predict a better execution. A sample of 254 children aged between 7 and 12 years from the city of Santa Fe, Argentina and belonging to different socioeconomic status were tested. A battery of executive functions sensitive to prefrontal function was used to obtain the results. These indicate a significant influence of age and SES on executive functions. The cognitive patterns follow a different path according to the development and SES effect. Besides, it is revealed a pattern of low cognitive functioning in low-SES children in all executive functions. Finally, from the variables included in this study, it was found that only the educational level of the mother and the housing conditions are associated to the children's executive function. The results are discussed in terms of the influence of the cerebral maturation and the environmental variables in the executive functioning.
