Which group matters more: The relative strength of minimal vs. gender and race group memberships in children's
Abstract:
Experimentally created "minimal" social groups are frequently used as a means to investigate core components of intergroup cognition in children and adults. Yet, it is unclear how the effects of such arbitrary group memberships compare to those of salient real-world group memberships (gender and race) when they are directly pitted against each other in the same studies. Across three studies, we investigate these comparisons in 4-7-year-olds. Study 1 (N = 48) establishes the minimal group paradigm, finding that children develop ingroup preferences as well as other forms of group-based reasoning (e.g., moral obligations) following random assignment to a minimal group. Study 2 (N = 96) and Study 3 (N = 48) directly compare this minimal group to a real-world social group (gender or race) in a cross-categorization paradigm, in which targets are participants' ingroups in terms of the minimal group and outgroups in terms of a real-world social group, or vice versa. The relative strength of the minimal group varies, but in general it either has a similar effect or a stronger effect as compared to race and in some cases even gender. Our results support the contention that an abstract tendency to divide the world into "us" and "them" is a central force in early intergroup cognition.
