UNLABELLED
Verbal fluency (VF) is a widely used tool in neuropsychological assessment.
OBJECTIVE
We aimed to investigate the influence of age and educational level on clustering and switching in three VF modalities: phonemic (PVF), semantic (SVF) and unconstrained (UVF). We evaluated type of cluster, mean cluster size, and quantity of clusters, intersections, and returns. A total of 260 healthy subjects were assessed.
METHODS
Participants were divided into three age groups: young adults (18 to 39 years), middle-aged adults (40 to 59 years) and older adults (60 to 80 years) and into two groups of educational level: 1-8 years (low), 9 years or more (high). A two-way ANOVA analysis was conducted to analyze the effect of age and educational level and its interactions. A repeated measures ANOVA was performed to verify the performance during the task.
RESULTS
A main effect of age was detected on the UVF and SVF scores for total switches, taxonomic clusters, and for the total semantic clusters on the SVF. There was a greater effect of educational level on total switches (UVF, PFV and SVF), taxonomic clusters (UVF and SVF), thematic clusters and total semantic cluster (UVF), phonemic and mixed clusters (PVF), mean cluster size (UVF and SVF) and intersections (SVF). Educational level had a greater effect on all three VF tasks.

言语流畅性（VF）是神经心理学评估中广泛使用的工具。
目的
我们旨在研究年龄和教育水平对三种言语流畅性模式（音素性言语流畅性（PVF）、语义性言语流畅性（SVF）和无限制言语流畅性（UVF））中的聚类和转换的影响。我们评估了聚类类型、平均聚类大小以及聚类、交叉点和返回的数量。共评估了260名健康受试者。
方法
参与者被分为三个年龄组：青年成年人（18至39岁）、中年成年人（40至59岁）和老年成年人（60至80岁），并分为两个教育水平组：1至8年（低）、9年或以上（高）。进行双向方差分析以分析年龄和教育水平的影响及其相互作用。进行重复测量方差分析以验证任务期间的表现。
结果
在UVF和SVF总分的转换、分类聚类以及SVF的总语义聚类方面检测到年龄的主要影响。教育水平对总转换（UVF、PFV和SVF）、分类聚类（UVF和SVF）、主题聚类和总语义聚类（UVF）、音素和混合聚类（PVF）、平均聚类大小（UVF和SVF）和交叉点（SVF）有更大影响。教育水平对所有三项言语流畅性任务有更大影响。
