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.
本研究探讨了在整个学龄前阶段，抑制和工作记忆对灵活性的两个潜在组成部分——目标表征（通过混合成本评估）和转换执行（通过局部成本评估）——的各自贡献。到学龄前晚期（4岁6个月和5岁3个月），抑制和工作记忆表现均与混合成本相关，但与局部成本无关，而在早期（3岁9个月）未观察到相关性。抑制和工作记忆与灵活性的关系似乎在学龄前阶段后期出现，且主要由目标表征驱动。
