Steps of Reasoning in Children and Adolescents
通过一个新颖的图形化博弈实验，研究了从8岁到成年人的推理步骤发展轨迹，发现年龄影响均衡选择，但部分年幼者天生具备均衡推理能力，且均衡行为比例在五年级后趋于稳定。
We develop a novel graphical paradigm of a strict-dominance-solvable game to study the developmental trajectory of steps of reasoning between 8 years old and adulthood. Most participants play the equilibrium action either always or only when they have a dominant strategy. Although age is a determinant of equilibrium choice, some very young participants display an innate ability to play at equilibrium. Finally, the proportion of equilibrium play increases significantly until fifth grade and stabilizes afterward, suggesting that the contribution of age to equilibrium play vanishes early in life.
