When reading, low-level visual properties of text are acquired from central vision during brief fixational pauses, but the effectiveness of these properties may differ in older age. To investigate, a filtering technique displayed the low, medium, or high spatial frequencies of text falling within central vision as young (18-28 years) and older (65+ years) adults read. Reading times for normal text did not differ across age groups, but striking differences in the effectiveness of spatial frequencies were observed. Consequently, even when young and older adults read equally well, the effectiveness of spatial frequencies in central vision differs markedly in older age.
阅读时，中央凹短暂注视期间会获取文本的低水平视觉属性，但这些属性在老年人群中的有效性可能不同。为了进行研究，一种过滤技术在年轻（18-28 岁）和老年（65+岁）成年人阅读时，将中央凹内的文本的低、中、高空间频率显示出来。正常文本的阅读时间在年龄组之间没有差异，但观察到空间频率的有效性存在显著差异。因此，即使年轻和老年成年人的阅读能力相当，中央凹内空间频率的有效性在老年时也有明显差异。
