“…For example, when observers are asked to list attributes that people of their own and another race share, the differences between these groups are blurred, which produces a positive effect in the reduction of prejudice (Hall et al, 2009). Other tasks, such as behavioural mimicry and intergroup contact, are also based on the reduction of self-other differences and have been employed to decrease prejudice toward outgroup members (see Crips & Turner, 2009;Davis, Conklin, Smith, & Luce, 1996;Gaertner & Dovidio, 2000;Inzlicht, Gutsell, & Legault, 2012;Pettigrew & Tropp, 2006;Turner, Crisp, & Lambert, 2007).…”
