A set of psychophysical procedures is described for rapidly measuring visual functions such as spatial contrast sensitivity, flicker fusion, and rod and cone two-color increment thresholds in young children. The psychophysical procedures, disguised as electronic space games, use a forced-choice paradigm combined with the method of descending limits. Because children enjoy the tasks and are highly motivated, the tests yield good sensory thresholds in a short period of time. However, when thresholds from 6-8-year-old children are compared with those of adults, the children have slightly higher thresholds for all of the functions tested. The differences are ascribed to the tendency of children to adopt a guessing strategy when stimuli are close to threshold.
本文描述了一套心理物理学程序，用于快速测量幼儿的视觉功能，如空间对比敏感度、闪烁融合以及视杆和视锥细胞双色增量阈值。这些心理物理学程序伪装成电子太空游戏，采用强制选择范式并结合极限递减法。由于儿童喜欢这些任务且积极性很高，所以测试能在短时间内得出良好的感官阈值。然而，将6至8岁儿童的阈值与成年人的阈值进行比较时，儿童在所有测试功能上的阈值略高。这些差异归因于儿童在刺激接近阈值时倾向于采用猜测策略。
