Contrast sensitivity for a 3 cycles deg-1 sinusoidal grating in 7-10 month old infants was tested by presenting gratings and uniform fields on cylinders, with the former providing auditory reinforcement when the infant picked them up. The method shows that a contrast as low as 7.5% can commonly be detected at this age, compared with 1-2% for adults under comparable conditions. However, as the development of hand preferences with the task as an indicator of visual sensitivity, it is concluded that this method is not in its present form suitable for vision testing on a wide scale or in a clinical setting.
通过在圆柱体上呈现光栅和均匀视场来测试7至10个月大婴儿对3周期度-1正弦光栅的对比敏感度,当婴儿拿起光栅时会给予听觉强化。该方法表明,在这个年龄段通常可以检测到低至7.5%的对比度,而在类似条件下成年人的对比度为1%-2%。然而,由于以该任务作为视觉敏感度指标的手偏好发展情况,得出的结论是,这种方法目前的形式不适用于大规模或临床环境中的视力测试。
