In the partner choice phase, participants learned about prospective partners’ decisions in an Inequity Game. Decisions were represented by laminated coloured cards (green for accept and red for reject), which read either “accept” or “reject”, and resource allocations were represented by laminated pictures of Skittles. Coloured cards were stored in small brown paper bags on which were written the initials of children who had previously played the inequity game, represented here by “Partner 1” and “Partner 2”.
