Guerra et al., 2013: Recategorizing identities between European and African Portuguese children decreased bias against European Portugese among African Portugese children
Reference:
Summary:
9-11 year-old European and African Portuguese children worked together on a school-related activity in 45-minute weekly sessions for a month that was identified and functioned as either the “Portuguese team” (recategorization condition) or the “Portuguese team with Portuguese and African origin students” (dual identity condition). One month after the last interaction, African Portuguese children in the recategorization condition exhibited less bias against European Portuguese children as compared to both the dual identity condition and a no-treatment control condition in which students did not interact. European Portuguese children did not differ significantly by condition, but if anything the dual identity condition was more effective for them.
