Previous research has found that children can engage in rectification of pre-existing inequality by allocating more resources to individuals and groups of disadvantaged status, but less research has investigated how children address the inequalities using resources of different values, especially when they are linked to group membership (i.e., in-group or out-group member) in the first-party (Study 1) and third-party contexts (Study 2). To address these issues, children aged 5-6 years How children will react to pre-existing inequality, whether to rectify (allocate more to the disadvantaged), distribute equally, or perpetuate (allocate more to the advantaged), is an important issue in children's moral development Olson et al., 2011;. Empirical evidence showed that children as young as 4-year-olds were highly sensitive to the concern of equality and that 6-to 8-year-old children would rather throw away resources than distribute them unequally (Blake & Mcauliffe, 2011;Shaw & Olson, 2012;Wu & Gao, 2018). However, in the context of pre-existing inequality where one person has received more resources than another, the most equitable choice is to rectify inequalities by allocating more resources to the disadvantaged rather than by allocating them strictly equally. It has been found that young children seek to equalize resource distributions between others by allocating more resources to individuals with disadvantaged status, and this rectification of inequality increases with age (
