本研究的目的是调查5 - 14岁儿童视觉对比敏感度（CS）的发展。6个空间频率以及静态（0 Hz）和动态（8 Hz）条件在光性和暗性亮度水平下使用。结果显示，CS成熟程度显著，在11-12岁时达到成人样值。在低空间频率（< 2个周期/度）和动态条件下，这种发展更为明显。暗色CS比光色CS发育缓慢。这些结果提示大细胞视觉通路成熟较晚。(C) 2003爱思唯尔科学爱尔兰有限公司版权所有。
The purpose of this study was to investigate the development of visual contrast sensitivity (CS) in children between 5 and 14 years of age. Six spatial frequencies and static (0 Hz) and dynamic (8 Hz) conditions were used at photopic and scotopic luminance levels. The results revealed significant maturation of CS, which reached the adult-like values by 11-12 years of age. The development was more pronounced at low spatial frequencies (< 2 cycles/degree) and in the dynamic condition. The scotopic CS exhibited slower development than the photopic CS. These results suggest the late maturation of the magnocellular visual pathway. (C) 2003 Elsevier Science Ireland Ltd. All rights reserved.
