Jean Piaget's theory is a central reference point in the study of logico-mathematical development in children. One of the most famous Piagetian tasks is number conservation. Failures and successes in this task reveal two fundamental stages in children's thinking and judgment, shifting at approximately 7 years of age from visuospatial intuition to number conservation. In the current study, preschool children (nonconservers, 5-6 years of age) and school-age children (conservers, 9-10 years of age) were presented with Piaget's conservation-of-number task and monitored by functional magnetic resonance imaging (fMRI). The cognitive change allowing children to access conservation was shown to be related to the neural contribution of a bilateral parietofrontal network involved in numerical and executive functions. These fMRI results highlight how the behavioral and cognitive stages Piaget formulated during the 20th century manifest in the brain with age.
让·皮亚杰的理论是儿童数理逻辑发展研究的一个重要参考点。最著名的皮亚杰任务之一是数量守恒。在这项任务中的失败和成功揭示了儿童思维和判断的两个基本阶段，大约在 7 岁时从视觉空间直觉转变为数量守恒。在当前的研究中，学前儿童（非守恒者，5-6 岁）和学龄儿童（守恒者，9-10 岁）接受了皮亚杰的数量守恒任务，并通过功能磁共振成像（fMRI）进行监测。证明使儿童能够获得守恒的认知变化与涉及数字和执行功能的双侧顶叶-额叶网络的神经贡献有关。这些 fMRI 结果强调了 20 世纪皮亚杰制定的行为和认知阶段如何随着年龄的增长在大脑中表现出来。
