“…Several studies have documented a strict interaction between motor system and numerical representation (Fischer, Warlop, Hill, &, Fias, 2004;Badets & Pesenti, 2010, 2011 as well as the relationship between quantity, space, and decisional processes (Loetscher, Bockisch, Nicholls, & Brugger, 2010;Loetscher et al, 2008;Shaki & Fischer, 2013;Vicario, 2013). In this regard, spatial attention mechanisms might play a key role in explaining these forms of interaction in the human brain (Vicario, 2011;Vicario, Bonní, & Koch, 2011;Vicario, Caltagirone, & Oliveri, 2007;Vicario & Martino, 2010;Vicario, Martino, & Koch, 2013;Vicario et al, 2008;Vicario, Rappo, Pepi, & Oliveri, 2009;Vicario, Rappo, Pepi, Pavan, & Martino, 2012).…”
