Whereas concern for other’s outcomes – that is, Advantageous Inequity Aversion (AIA), has been shown to be a late emerging response to unfairness linked to reciprocity, reputation, and cultural norms of fairness, the concern for one own’s outcomes – that is, Disadvantageous Inequity Aversion (DIA), has been documented in children as young as 4-years of age in the Inequity game and it has been proposed to be linked to competition, spite, and an early emerging sense of fairness with a focus on the self. However, little work has examined whether implicit and explicit DIA is already present in children younger than 4, much less explored the cognitive mechanisms associated with its early development. Here, we examined whether DIA is present before 4-years of age (i.e., 2-year-olds) using an apparatus especially sensitive to implicit responses (Chapter 2), validated a methodology that weights implicit and explicit responses equally while showing that implicit and explicit DIA is already present by the second year of life (Chapter 3), and examined whether understanding the cardinal principle of counting or cardinal number word knowledge more generally is linked early in development to DIA finding support for the second hypothesis (Chapter 4).
