AIM
The purpose of the present study was to investigate if performance in a 30-s verbal semantic fluency task (i.e. animal naming) across five elderly aged groups (60-64; 65-69; 70-74; 75-79; 80-84 years) would be reflective of aging effect.
METHODS
We analyzed differences in performance across 5-s phases and the moment of first word production in these five age groups.
RESULTS
The following results were obtained: (i) with increasing age, the total number of words produced gradually declined (P < 0.001); (ii) there were significant differences in performance among the age groups in three phases (0-5, 6-10, 16-20 s) (P < 0.05); and (iii) the first word production within the first 5-s phase was significantly delayed in the 75-79 years and 80-84 years age groups compared with the rest of the age groups.
CONCLUSIONS
Performance in the initial 5-s phase might be sensitive to cognitive degeneration in normal older adults.
目的
本研究旨在调查五个老年年龄组（60 - 64岁；65 - 69岁；70 - 74岁；75 - 79岁；80 - 84岁）在30秒言语语义流畅性任务（即动物命名）中的表现是否能反映衰老效应。
方法
我们分析了这五个年龄组在5秒时间段以及首个单词产出时刻的表现差异。
结果
得到以下结果：（i）随着年龄增长，产出的单词总数逐渐下降（P < 0.001）；（ii）在三个阶段（0 - 5秒、6 - 10秒、16 - 20秒）各年龄组的表现存在显著差异（P < 0.05）；（iii）与其他年龄组相比，75 - 79岁和80 - 84岁年龄组在首个5秒阶段内的首个单词产出明显延迟。
结论
在最初的5秒阶段的表现可能对正常老年人的认知衰退敏感。
