“…In their scientific literature analysis about ethnic prejudices, Clark et al, (2017) mentioned studies that had shown tendencies of light-skinned boys and girls, from kindergarten to elementary school, to positively rate subjects or groups with their skin colour and to evaluate those who had dark skin tones negatively (Williams & Morland, 1976;Aboud, 1988;Katz & Kofkin, 1997;Bernstein et al, 2000;Baron & Banaji, 2004;McGlothlin & Killen, 2006;Gibson et al, 2015), especially when the former had no direct contact with the latter (Radke & Sutherland, 1949;George & Hoppe, 1979;Jarrett, 1981). However, several studies have shown that older girls and boys develop positive attitudes towards each other (Katz & Zalk, 1978;Cameron et al, 2007;Verkuyten & De Wolf, 2007), having a greater capacity for «reconciliation», that is, the ability to recognize preferences other than one's own as equally valid and just, compared to younger girls and boys (Johnson & Aboud, 2017).…”
