年轻人和老年读者的眼球运动被记录下来，因为他们阅读的句子包含的目标词的频率或可预测性不同。此外，一半的句子是用容易阅读的字体（Times New Roman）打印的，另一半是用更难阅读的字体（古英语）打印的。词频，字的可预测性，字体难度的影响是明显的两组读者的眼动数据。在固定时间数据中，结果的模式是相同的，但老年读者比年轻读者有更大的频率和可预测性的影响。年龄较大的读者比年轻读者更经常地跳过单词（如他们对选定目标词的跳过率所示），但他们更多地回归到目标词，总体上更多地回归。E-Z Reader模型被用作评估结果的平台，使用该模型的模拟表明，老年读者的词汇处理速度较慢，可能因此，他们采取了更冒险的阅读策略。
Young adult and older readers' eye movements were recorded as they read sentences containing target words that varied in frequency or predictability. In addition, half of the sentences were printed in a font that was easy to read (Times New Roman) and the other half were printed in a font that was more difficult to read (Old English). Word frequency, word predictability, and font difficulty effects were apparent in the eye movement data of both groups of readers. In the fixation time data, the pattern of results was the same, but the older readers had larger frequency and predictability effects than the younger readers. The older readers skipped words more often than the younger readers (as indicated by their skipping rate on selected target words), but they made more regressions back to the target words and more regressions overall. The E-Z Reader model was used as a platform to evaluate the results, and simulations using the model suggest that lexical processing is slowed in older readers and that, possibly as a result of this, they adopt a more risky reading strategy.
