ABSTRACT This study used a novel approach that combined the latency and accuracy scores to examine the relative involvement of inhibition and working memory in two measures of cognitive flexibility – mixing cost and switch cost in 110 Nigerian adolescents. Results showed that inhibition was significantly associated with switch cost. On the other hand, working memory was negatively associated with mixing cost. These findings support the assumption that cognitive flexibility skills are dependent on inputs from inhibition and working memory processes. Inhibition is involved in the deactivation of irrelevant stimuli during switching trials while working memory is essential to maintain the current rule in sets that require no shifting.

工作记忆和抑制对尼日利亚青少年认知灵活性的贡献

摘要 本研究使用了一种结合延迟和准确度分数的新方法来检查抑制和工作记忆在认知灵活性的两种测量中的相对参与度——混合成本和 110 名尼日利亚青少年的转换成本。结果表明，抑制与转换成本显着相关。另一方面，工作记忆与混合成本呈负相关。这些发现支持认知灵活性技能依赖于抑制和工作记忆过程的输入的假设。抑制涉及在转换试验期间不相关刺激的失活，而工作记忆对于在不需要转移的集合中维持当前规则至关重要。
