“…However, in light of the increasingly documented impact of environmental input on children's brain development (Chugani et al, 2001;Marshall & Fox, 2004) and the protracted postnatal development of prefrontal areas in particular (Duncan, 2001;Paus et al, 1999), some authors have suggested that the study of environmental influences, particularly early parent-child relationships, is likely to be useful in understanding individual differences in children's EF (Carlson, 2003;Fonagy & Target, 2002;Glaser, 2000) and related higher mental functions (Fernyhough, 1996;Fernyhough, 2008). Indirect support for the putative role of parent-child relationships in EF development stems from studies that have found parenting to relate to constructs bearing many similarities to some components of EF, labeled (for instance) as self-regulation (Jennings et al, 2008;LeCuyer & Houck, 2006) or effortful control (Kochanska et al, 2000;Poehlmann et al, 2010), or referring to child performance on cognitive tasks similar to those used to measure EF (Diaz, Neal, & Vachio, 1991). In addition, a very recent body of research is beginning to provide direct support for the idea that parenting plays an important role in the development of child EF per se (e.g., Bernier et al, 2010;Bernier, Carlson, Deschênes, & Matte-Gagné, in press;Bibok, Carpendale, & Müller, 2009;Hughes & Ensor, 2009;Landry, Miller-Loncar, Smith, & Swank, 2002).…”
