Traditional theories of cognitive development predict that children pr
ogress from intuitive to computational thinking, whereas fuzzy-trace t
heory makes the opposite prediction. To evaluate these alternatives, f
raming problems were administered to preschoolers, second graders, and
fifth graders. Consistent with fuzzy-trace theory, results indicated
(a) that younger children focused on quantitative differences between
outcomes and did not exhibit framing effects (risk avoidance for gains
, risk seeking for losses) and (b) that older children assimilated the
se quantitative differences and displayed framing effects.
