有研究表明，患有中央视野丧失（CFL）的读者可能无法像正常视力的读者那样利用上下文来促进阅读，因为他们的处理能力被充分利用来解码退化的视觉刺激。如果这是真的，这可以解释他们阅读缓慢的原因，即使文本被适当放大。患有CFL的读者和视力正常、年龄匹配的对照组从两个动态文本显示中阅读句子和随机单词列表。我们使用句子增益（句子与随机单词的阅读率之比）来评估上下文的使用。各组之间的句子增加是相同的。因此，对语境依赖的减少并不能解释CFL患者阅读速度较慢的原因。
It has been suggested that readers with central field loss (CFL) may not be able to use context to facilitate reading in the same way that normally sighted readers do because their processing capacity is fully utilized decoding the degraded visual stimulus. If true, this could account for their slow reading, even when text is appropriately magnified. Readers with CFL and normally sighted, age-matched controls read sentences and lists of random words from two dynamic text displays. We used sentence-gain (the ratio of reading rates for sentences to random words) to assess the use of context. Sentence-gain was equivalent across groups. Therefore, reduced reliance on context cannot explain the slower reading rates of people with CFL.
