最常用的言语流畅范例是语义和字母流畅任务。研究表明，这些范式访问语义记忆和执行功能，并且对额叶干扰敏感。巴西样本中关于这些范式的研究很少。 目的：本研究调查了巴西儿童的表现以及年龄对言语流畅性任务的影响。将结果与其他研究的结果进行比较，呈现评分标准数据的一致性。方法：对119名儿童（7～10岁）进行样本，进行三项音素流畅性（F、A、M）任务和三项语义流畅性（动物、衣服、水果）任务。三十名受试者的成绩由两名独立审查员进行评分。结果：两名独立审查员计算的分数之间存在显着的正相关关系。语义流畅性任务和音素流畅性任务的表现之间发现显着的正相关。年龄对这两项任务的影响都很显着，7 岁和 9 岁受试者之间以及 7 岁和 10 岁受试者之间存在显着差异。 8 岁组与其他年龄组没有差异。结论：结果模式与之前巴西和国际研究中观察到的结果相似。
The most used verbal fluency paradigms are semantic and letter fluency tasks. Studies suggest that these paradigms access semantic memory and executive function and are sensitive to frontal lobe disturbances. There are few studies in Brazilian samples on these paradigms.OBJECTIVE: The present study investigated performance, and the effects of age, on verbal fluency tasks in Brazilian children. The results were compared with those of other studies, and the consistency of the scoring criteria data is presented.METHODS: A sample of 119 children (7 to 10 years old) was submitted to the three phonemic fluency (F, A, M) tasks and three semantic fluency (animals, clothes, fruits) tasks. The results of thirty subjects were scored by two independent examiners.RESULTS: A significant positive correlation was found between the scores calculated by the two independent examiners. Significant positive correlations were found between performance on the semantic fluency task and the phonemic fluency task. The effect of age was significant for both tasks, and a significant difference was found between the 7- and 9-year-old subjects and between the 7- and 10-year-old subjects. The 8-year-old group did not differ to any of the other age groups.CONCLUSION: The pattern of results was similar to that observed in previous Brazilian and international studies.
