我们通过观察中央凹旁处理来测试阅读中眼动控制的理论。根据注意加工理论，只有当固定单词 n 的处理完成时，注意力才会转向单词 n+1，因此，直到对单词 n+1 的扫视编程开始编程时，注意旁中心加工才开始（Henderson &, Ferreira, 1990；Morrison, 1984），甚至在单词 n 的处理时间太长时才开始（Henderson & Ferreira, 1990）。无论中心凹处理负载如何，中心凹旁预览益处都应该是恒定的（Morrison，1984），或者当处理单词 n 超过眼动编程截止日期时应该减少（Henderson＆Ferreira，1990）。通过操纵中央凹单词 n 的频率和长度以及中央凹单词 n+1 的可见性，我重复了这样的发现：中央凹视觉中的低频单词对中央凹预览的好处较小。然而，详细分析表明，眼动编程时限假说无法解释这一发现，这不是由于低频词 n 接受长时间注视的情况，而是由于短注视时间小于 240 毫秒的情况。此外，存在单词n到单词n+1的溢出效应，并且存在两个单词的并行处理的元素。结果更符合并行处理，但受限于注视点 n 上的中央凹单词处理可以与注视点 n+1 上的中央凹 n 字处理相结合的程度。
We tested theories of eye movement control in reading by looking at parafoveal processing. According to attention-processing theories, attention shifts towards word n+1 only when processing of the fixated word n is finished, so that attended parafoveal processing does not start until the programming of the saccade programming to word n+1 is initiated (Henderson &, Ferreira, 1990; Morrison, 1984), or even later when the processing of word n takes tao long (Henderson & Ferreira, 1990). Parafoveal preview benefit should be constant whatever the foveal processing load (Morrison, 1984), or should decrease when processing word n outlasts an eye movement programming deadline (Henderson & Ferreira, 1990). By manipulating the frequency and length of the foveal word n and the visibility of the parafoveal word n+1, me replicated the finding that the parafoveal preview benefit is smaller with a low-frequency word in foveal vision. Detailed analyses, however, showed that the eye movement programming deadline hypothesis could not account for this finding which was due not to cases where the low-frequency words n had received a long fixation, but to cases of a short fixations less than 240 msec. In addition, there mas a spill-over effect of word n to word n+1, and there was an element of parallel processing of both words. The results are more in line with parallel processing limited by the extent to which the parafoveal word professing on fixation n can be combined with the foveal n ord processing on fixation n+1.
