The original rotor pursuit test requires that the subject attempts to keep a metal stylus in contact with a small metal disk that was placed in the surface of a turntable that rotated at a constant speed. The present study evaluated the Psychology Experiment Building Language (PEBL) pursuit rotor task. Children (N=427, ages 9-13, 44.4% females) completed a handedness inventory followed by four pursuit rotor trials with each hand. The total time on target increased with age with the dominant as well as non-dominant hands. A small, but significant, sex difference favoring males was also observed. Dextrals spent more time on target than sinistrals with their dominant hand but the reverse pattern was observed for the non-dominant hand. These group differences were independent of prior computer experience. These findings indicate that the freely downloadable PEBL pursuit rotor task is a useful measure of psychomotor function (http://pebl.sf.net) in children and adolescents.
原始的转子追踪测试要求被试者试图让一个金属触针与一个放在旋转台表面的小金属盘保持接触，该旋转台以恒定速度旋转。本研究评估了心理学实验构建语言（PEBL）的转子追踪任务。儿童（N=427，年龄 9-13 岁，女性占 44.4%）完成了一份惯用手问卷，然后用每只手完成了四次转子追踪试验。主导手和非主导手的目标时间都随着年龄的增长而增加。也观察到一个较小但显著的男性优势性别差异。惯用右手的人比惯用左手的人在目标上花费的时间多，但在非主导手上则相反。这些组间差异与之前的计算机经验无关。这些发现表明，可免费下载的 PEBL 转子追踪任务是一种测量儿童和青少年心理运动功能的有用方法（http://pebl.sf.net）。
