“…Executive functions are necessary to acquire, combine and select spatial strategies, to plan and monitor behavioral motor responses according to environmental requirements (Lithfous et al, 2013;Vasilyeva & Lourenco, 2012). Some evidence has indeed reported strong associations between egocentric encoding and executive functions (e.g., Borella, Carretti, & De Beni, 2008;Iachini et al, 2005;Lithfous et al, 2013;Ruggiero, Sergi, & Iachini, 2008;Sanders, Holtzer, Lipton, Hall, & Verghese, 2008; see also Cornoldi & Vecchi, 2003;Craik, 1986;Meneghetti, Fiore, Borella, & De Beni, 2011;Park, 2000). Similarly, in childhood, the capacity to efficiently use reference frames would occur at about 6 years or later (Nardini et al, 2008(Nardini et al, , 2009Vasilyeva & Lourenco, 2012), as a consequence of delayed maturation of hippocampus and surrounding areas and frontal lobes as proved by myelination process, gray matter reduction, synaptogenesis, and resting metabolism (e.g., Fuster, 2002;Lenroot & Giedd, 2006;Newcombe & Huttenlocher, 2003;Pfefferbaum et al, 1994;Tsujimoto, 2008).…”
