Constraints on learning, rather than being unique to evolutionarily privileged domains, may operate in nonprivileged domains as well.

THe presente experiments showed that children can use their conceptual understanding to accurately evaluate strategies that they not only do not yet use but hat are more conceptually advanced than the strategies they do not use. In Experiment 1, 5-year-olds who did not yet use the min strategy
