很少有研究对知觉-认知专长的总体保持进行调查，更少有不同年龄段的教练进行比较。这项研究的目的是测试不同年龄段、执照水平以及它们之间的知觉-认知差异。本研究调查了三种不同技能水平的中青年教练员在技能表现上的差异。参与者进行了面向准确性的图形回忆(以像素为单位的平均距离)和以时间为导向的闪烁测试(以ms为单位的平均检测时间)。在两个测试中，年龄组之间和技能组之间有一些显著的差异，但没有交互作用。对于图形回忆测试，技能水平差异的效应大小更大，而对于闪烁测试，年龄的效应更大。这些结果表明，与反应计时任务相比，教练能够更好地保持准确性技能。这与在普通人群中表现加快的研究结果是一致的，后者显示出随着年龄的增长而下降。此外，结果还支持关于准确性很重要的技能知觉专长的研究结果。
There is little research investigating the maintenance of perceptual-cognitive expertise in general and even less comparing coaches of different ages. The aim of this study was to test for perceptual-cognitive differences between age groups, licence levels, and their interaction. This study investigated differences in skilled performance between young and middle-aged coaches of three different skill levels. Participants performed an accuracy-oriented pattern recall (mean distance in pixel) and a time-oriented flicker test (mean detection time in ms). There were some significant differences between age groups and between skill groups for both tests, but no interactions. For the pattern recall test, the effect sizes were larger for skill level differences, while for the flicker test effects were larger for ageing. These results suggest coaches are able to maintain accuracy skills better than reaction timed tasks. This is in line with findings on speeded performance in general populations, which show declines with age. Moreover, results also support findings on perceptual expertise in skills where accuracy was important.
