When (and When Not) to Make Exceptions: Links among Age, Precedent Setting Decisions, and Argument Evaluation

Negative precedents are set when, in the absence of mitigating conditions, social rules are not enforced by relevant authorities. This study examined the effects of normative (i.e., to enforce rules) and nonnormative arguments (i.e., to "make exceptions") on decisions that could establish negative precedents and whether those effects differed for children and adolescents. As expected, on baseline problems, age correlated positively with decision-making performance. After receiving normative arguments, normative decisions increased and adolescents-but not preadolescents-transferred their understanding to novel problems. Nonnormative arguments led to decrements in normative decisions across ages. However, only for preadolescents did performance decrements following nonnormative arguments transfer to novel problems. Discussion focuses on the abilities to engage in "metacognitive intercession," variability in children's and adolescents' decisions, and developments in the understanding of the consequences of violating the social rules.
