“…Another, not mutually exclusive, possibility is that SES differences in brain development are evidence of children acquiring the same ultimate skills but in different, contextually-dependent ways. Interestingly, accumulating evidence supports the possibility that children might rely on different neurocognitive mechanisms to solve the same executive functioning tasks ( Ellwood-Lowe et al, 2021 , Ellwood-Lowe et al, 2022 , Finn et al, 2017 , Leonard et al, 2022 , Merz et al, 2019 , Sheridan et al, 2012 ). For example, one study found that children whose families had lower incomes activated an area of the prefrontal cortex more than their peers from higher-income families when performing a working memory task, and that activation of this region was positively linked to performance for children from lower-SES-backgrounds, but negatively linked to performance for children from higher-SES backgrounds ( Sheridan et al, 2012 ).…”
