许多评论神经心理学评估的人都强调用百分位数来表示考试成绩的缺点。因此，有一种忽视基本原理的危险：百分位排名以一种与神经心理学家更相关的形式表达分数，而不是任何其他指标，因为它们直接告诉我们这些分数在正常人群中有多常见或不常见。我们主张，除了用标准指标来表达分数外，神经心理学家还应该定期记录所有测试分数的百分位排名，以便后者在试图得出公式时可用。此外，有人认为，目前在标准分数度量上表示测试分数的置信限的做法，应该用百分位数等级表示的置信限加以补充，因为后者提供了围绕观察到的分数的不确定性的更直接和有形的指示。本文附带了计算机程序，可用于获得wis - iii或wis - iv的指数分数（和FSIQs）的百分位秩置信限（这些可从以下网页下载：http://www.abdn.ac.uk/psy086/dept/PRCLME.htm）。
Many commentators on neuropsychological assessment stress the disadvantages of expressing test scores in the form of percentile ranks. As a result, there is a danger of losing sight of the fundamentals: percentile ranks express scores in a form that is of greater relevance to the neuropsychologist than any alternative metric because they tell us directly how common or uncommon such scores are in the normative population. We advocate that, in addition to expressing scores on a standard metric, neuropsychologists should also routinely record the percentile rank of all test scores so that the latter are available when attempting to reach a formulation. In addition, it is argued that the current practice of expressing confidence limits on test scores on a standard score metric should be supplemented with confidence limits expressed as percentile ranks, because the latter provide a more direct and tangible indication of the uncertainty surrounding an observed score. Computer programs accompany this paper and can be used to obtain percentile rank confidence limits for Index scores (and FSIQs) on the WAIS-III or WISC-IV (these can be downloaded from the following web page: http://www.abdn.ac.uk/psy086/dept/PRCLME.htm).
