The aim of this study is to analyze and compare the performance and strategies used by control subjects and patients with unilateral brain damage on phonemic and semantic Verbal Fluency tasks.
The sample consisted of 104 participants divided into four groups (26 with left hemisphere damage and aphasia- LHDa, 28 with left hemisphere damage and no aphasia- LHDna, 25 with right hemisphere damage- RHD and 25 neurologically healthy control subjects). All participants were administered the phonemic ("M" letter-based) and semantic (animals) verbal fluency tasks from the Montreal-Toulouse Language Assessment Battery (MTL-BR).
Patients in the LHDa group showed the worst performance (fewer words produced, fewer clusters and switches) in both types of fluency task. RHD group showed fewer switching productions when compared with controls and LHDna had fewer words productions than controls in the first 30 seconds block.
Our findings suggest that the LHDa group obtained lower scores in most measures of SVF and PVF when compared to the other groups.
本研究旨在分析和比较单侧脑损伤患者和对照组在音位和语义流畅性任务中的表现和策略。
样本由 104 名参与者组成，分为四组（26 名左侧大脑损伤伴失语症- LHDa、28 名左侧大脑损伤无失语症- LHDna、25 名右侧大脑损伤- RHD 和 25 名神经健康对照组）。所有参与者都接受了来自蒙特利尔-图卢兹语言评估电池（MTL-BR）的音位（基于“M”字母）和语义（动物）流畅性任务。
LHDa 组在两种流畅性任务中的表现最差（产生的单词较少，簇和转换较少）。与对照组相比，RHD 组在转换生成方面较少，而在最初的 30 秒组中，LHDna 产生的单词比对照组少。
与其他组相比，LHDa 组在大多数 SVF 和 PVF 测量中得分较低。
