在一项实验中评估了Farnsworth‐Munsell 100‐Hue测试（100‐Hue测试）中练习对系列表现的影响程度和持久性，其中6名受试者在6周内进行了100‐Hue测试，最多17次，然后在7个月后再进行一次。实践效果的出现在整个群体（P < 0.001）和三个个体受试者（P < 0.05）中具有高度的统计学显著性。在最后一次测试性能后7个月，实践效果仍然明显。在5-10次重测后，错误分数几乎降为零，因此尚不清楚练习的效果是否已经消失，或者未能进一步提高是否是一种“地板效应”。作为对地板效应的对照，进行了第二个实验，其中通过将中性密度过滤器放置在受试者的眼睛中来损害受试者的表现（从而人为地提高他们的100-Hue错误分数）在这些条件下，错误分数继续下降，并在17次测试后减半（P < 0.03）。得出的结论是，实践对100‐Hue测试性能有很大的影响，这种影响在多次重新测试和测试后的数月内持续存在。
The extent and persistence of practice effects on serial performance in the Farnsworth‐Munsell 100‐Hue test (100‐Hue test) were evaluated in an experiment in which six subjects performed the 100‐Hue lest up to 17 times over six weeks, and then once more after 7 months. A practice effect occurred which was highly statistically significant for the group as a whole (P < 0.001) and for three individual subjects (P < 0.05). A practice effect was still evident 7 months after the last test performance. Error scores were reduced almost to zero after 5–10 retests so that it was unclear whether the effects of practice had disappeared or whether failure to improve further was a ‘floor effect’. As a control against a floor effect, a second experiment was performed in which subjects’performance was impaired by placing neutral density filters in from of their eyes (thus artificially raising their 100‐Hue error score) Under these conditions, error scores continued to fall and were halved after 17 tests (P < 0.03). It is concluded that practice has a large effect on 100‐Hue test performance which continues over many retests and for many months after testing.
