Verbal fluency (VF) tasks are extensively used to measure strategic retrieval and executive functioning. Results for total production of words, clustering and switching strategies, and performance over time for Spanish-speaking children are provided. A total of 120 children, ranging in age from 8 to 11, were divided by age into two groups and evaluated. A higher total score for words produced in the semantic compared with the phonological task, a correlation between clustering and switching strategies and total score, and decreased task performance over time were evidenced. These scores were higher in the older group. Moreover, an association was found between verbal fluency tasks, strategies employed, and cognitive executive functions. This indicates that clustering and switching strategies provide indicators of strategic retrieval and executive processes. Together the results suggest that these fluency scores are valuable to measure underlying cognitive processes and retrieval strategies and therefore could be useful to assess executive function deficits in children.
言语流畅性（VF）任务被广泛用于衡量策略性检索和执行功能。本文提供了西班牙语儿童在总词汇产出、聚类和转换策略以及随时间推移的表现方面的结果。共有 120 名年龄在 8 至 11 岁的儿童按年龄分为两组进行评估。结果表明，与语音任务相比，语义任务的词汇产出总分更高，聚类和转换策略与总分呈正相关，且随时间推移任务表现下降。这些分数在年龄较大的组中更高。此外，言语流畅性任务、所采用的策略与认知执行功能之间存在关联。这表明聚类和转换策略提供了策略性检索和执行过程的指标。综合结果表明，这些流畅性评分可用于衡量潜在的认知过程和检索策略，因此可能有助于评估儿童的执行功能缺陷。
