这项研究探讨了整个学龄前阶段抑制和工作记忆对灵活性的两个基本组成部分的各自贡献，即目标表征（根据混合成本评估）和转换实施（根据当地成本评估）。到学龄前后期（4岁零6个月和5岁零3个月），抑制和工作记忆表现都与混合成本相关，但与局部成本无关，而早期（3岁零9个月）则没有观察到任何关系。抑制和工作记忆与灵活性的关系似乎出现在学龄前后期，并且主要由目标表征驱动。
This study addressed the respective contributions of inhibition and working memory to two underlying components of flexibility, goal representation (as assessed by mixing costs) and switch implementation (as assessed by local costs), across the preschool period. By later preschool age (4 years 6 months and 5 years 3 months), both inhibition and working-memory performance were associated with mixing costs, but not with local costs, whereas no relation was observed earlier (3 years, 9 months). The relations of inhibition and working memory to flexibility appear to emerge late in the preschool period and are mainly driven by goal representation.
