语言流畅性测试，无论是语义流畅性（SF）还是语音流畅性（PF），通常被用作神经心理学评估的标准方法。然而，可用的以英国样本为标准的规范性数据很少，而且人们对这些任务中常用的“简短形式”的实用性知之甚少。此外，很少有人知道言语流畅性测试的重测reliability.In这份报告中，我们描述了N = 365正常参与者的表现SF的版本需要生成的范例类别的“动物”和PF任务的版本，需要参与者生成的话开始的字母“B”。从这些数据中，我们得到了这两项任务的百分位分布，我们还讨论了性别、年龄、受教育年限和智商对SF和PF表现的影响。没有性别差异被发现在PF或SF任务。年龄和SF之间存在显著但很小的相关性，但与PF无关。受教育年限与智商、PF和SF表现之间也存在适度的相关性。我们还报告了SF和PF任务的重测信度分数。在较长的“FAS”版本上的表现与仅使用字母“B”获得的分数高度相关。这表明，从管理三个字母版本的PF获得的额外优势很小。还观察到，在SF桶中，参与者被给予1分钟，而当参与者被给予1分30秒时获得的分数之间具有极高的相关性。最后，为了帮助用户确定重新测试分数的变化是由于测量错误还是真实的影响，我们计算了预测标准误差（SEP）评分。
Tests of verbal fluency, whether of Semantic Fluency (SF) or Phonological Fluency (PF), are often used as a standard method of neuropspchological assessment. However, very little normative data, standardized on a UK sample, is available, and little is known about the utility of popularly used 'short-forms' of these tasks. Additionally, very little is known about verbal fluency test-retest reliability.In this report we describe the performance of N = 365 normal participants on a version of SF requiring the generation of exemplars of the category 'animals' and a version of the PF task requiring participants to generate words beginning with the letter 'B'. From this data we have derived a percentile distribution for both tasks.We also addressed the impact of sex, age, years of education and IQ upon both SF and PF performance. No sex differences were found on either the PF or the SF tasks. A significant but small correlation between age and SF, but not PF, was observed. Modest correlations between both years of education and IQ and PF and SF performance were also seen. We also report test-retest reliability scores for performance on both SF and PF tasks. Performance on the longer 'FAS' Version was found to correlate highly with scores obtained using just the letter 'B'. This suggests that little additional advantage obtains from administering three-letter versions of PF. An extremely high degree of correlation between SF casks in which participants are given 1 minute and scores obtained when participants are given 1 minute 30 seconds was also observed.Finally, in order to assist users in deciding whether a changed retest score is due to error measurement or a real effect, we calculated Standard Error of Prediction (SEP) scores.
