Emerging work in semantic cognition has begun to elucidate the interaction between the structure of semantic memory and processes mediating goal-directed memory retrieval. Despite having essential implications for basic and applied research, these objectives remain neglected in both the assessment and interpretation of semantic verbal fluency (SVF) tasks. To test the association between semantic structure and the controlled processes underlying verbal fluency, we assessed how the degree of partitioning (modularity) of SVF responses into semantic clusters moderates the relationship of retrieval fluency with working memory and interference control capacities. We found that working memory capacity predicted retrieval fluency in individuals whose SVF responses were arranged in fine-grained semantic clusters (high modularity), whereas interference control was more predictive of retrieval fluency for individuals who delivered responses of low modularity. Our data support the presumed role of working memory and interference control in SVF and provide novel evidence that relative demands on these capacities are predicted by the organisation of semantic knowledge.
新兴的语义认知研究开始阐明语义记忆结构与目标导向记忆检索中介过程之间的相互作用。尽管这对基础和应用研究具有重要意义，但在语义流畅性测试 (SVF) 任务的评估和解释中，这些目标仍然被忽视。为了检验语义结构与流畅性背后的受控过程之间的关联，我们评估了 SVF 反应的语义聚类程度 (模块性) 如何调节检索流畅性与工作记忆和干扰控制能力之间的关系。我们发现，在 SVF 反应被精细地组织成语义聚类的个体中（模块性高），工作记忆容量可以预测检索流畅性，而在那些反应模块性低的个体中，干扰控制能力则更能预测检索流畅性。我们的数据支持工作记忆和干扰控制在 SVF 中的假定作用，并提供了新的证据，即这些能力的相对需求取决于语义知识的组织。
