我们比较了3-10岁的成人和儿童对一阶和二阶运动和形式的敏感性。对于一阶刺激，所有年龄段的运动敏感性都优于形式，运动阈值在6 Hz时优于1.5 Hz。对于二阶刺激，所有年龄段的形式敏感性优于运动敏感性，运动阈值在0.25周期/度时优于1周期/度。运动的阈值比形式的阈值更晚，一阶刺激的阈值比二阶刺激的阈值更晚。对于一阶刺激，随年龄的变化更大，持续时间更长。2009爱思唯尔有限公司版权所有。
We compared the sensitivity of adults and children aged 3-10 years to first- and second-order motion and form. For first-order stimuli, at all ages sensitivity was better for motion than form, and motion thresholds were better at 6 Hz than at 1.5 Hz. For second-order stimuli, at all ages sensitivity was better for form than motion, and motion thresholds were better at 0.25 cyc/deg than at 1 cyc/deg. Thresholds became adult-like later for motion than for form and later for first-order than second-order stimuli. For first-order stimuli, the changes with age were larger and more protracted.
