对比敏感度功能，获得了5-12周的婴儿。灵敏度来自固定偏好静态或漂移正弦光栅在一个统一的领域，评估由2-替代强迫选择由一个盲人观察员。在敏锐度，低频切割的程度和整体灵敏度方面，5周组和老年组之间存在较大差异。这种表现上的差异可能反映了前3个月视觉系统的快速神经发育。生命
Contrast sensitivity functions were obtained for infants aged 5-12 wk. Sensitivity was derived from fixation preference for static or drifting sinusoidal gratings over a uniform field, assessed by 2-alternative forced choice by a blind observer. In terms of acuity, extent of the low-frequency cut and overall sensitivity, there were large differences between the 5 wk group and older age groups. This difference in performance may reflect rapid neural development in the visual system over the first 3 mo. of life.
