“…For example, de Heering and colleagues (2007) found that 4-, 5-and 6-year-olds displayed similar susceptibility to each other and to adults when tested using the original matching procedure (see also Carey & Diamond, 1994;Mondloch, Pathman, Maurer, Le Grand, & de Schonen, 2007;Susilo, Crookes, McKone, & Turner, 2009). Comparable results have also been reported for expression composites (Durand, Gallay, Seigneuric, Robichon, & Baudouin, 2007). Susceptibility, however, may be present at an even younger age.…”
