四个不同年龄组（8-9岁、11-12岁、13-15岁和年轻人）执行空间规则切换任务，其中必须根据反馈或切换线索检测排序规则。根据最近引入的威斯康星卡片分类任务错误评分方法（WCST；Barcelo & Knight.2002）检查性能错误。这种方法使我们能够区分由于维护设置失败（分心错误）和由于切换设置失败而导致的错误（持续性错误）。表现错误的预期年龄差异在 8-9 岁和 11-12 岁之间的持续性错误中最为明显，但是，对于分心错误，直到 13-15 岁才达到成人水平。这些发现被解释为支持集合切换和集合维持遵循不同的发展轨迹的观点。
Four different age groups (8-9-year-olds, 11-12-year-olds 13-15-year-olds and young adults) performed a spatial rule-switch task in which the sorting rule had to be detected on the basis of feedback or on the basis of switch cues. Performance errors were examined on the basis of a recently introduced method of error scoring for the Wisconsin Card Sorting Task (WCST; Barcelo & Knight. 2002). This method allowed us to differentiate between errors due to failure-to-maintain-set (distraction errors) and errors dire to failure-to-switch-set (perseverative errors). The anticipated age differences in performance errors were most pronounced for perseverative errors between 8-9 years and 11-12 years, but,for distraction errors adult levels were not reached until 13-15 years. These findings were interpreted to support the notion that set switching and set maintenance follow distinct developmental trajectories.
