title: Linking childhood poverty and cognition: environmental mediators of non-verbal executive control in an Argentine sample.
abstract: Tests of attentional control, working memory, and planning were administered to compare the non-verbal executive control performance of healthy children from different socioeconomic backgrounds. In addition, mediations of several sociodemographic variables, identified in the literature as part of the experience of child poverty, between socioeconomic status and cognitive performance were assessed. Results show: (1) significant differences in performance between groups in most dependent variables analyzed - however, not in all variables associated with attentional control domains; (2) significant indirect effects of literacy activities on working memory and fluid processing domains, as well as computer resources effects on fluid processing; and (3) marginal indirect effects of computer resources on attentional control and working memory domains. These findings extend analysis of the impact of poverty on the development of executive control, through information based on the assessment of combined neurocognitive paradigms and the identification of specific environmental mediators.
