We investigated small temporal nonalignments between the two eyes’ fixations in the reading of English and Chinese. We define nine different patterns of asynchrony and report their spatial distribution across the screen of text. We interpret them in terms of their implications for ocular prevalence—prioritizing the input from one eye over the input from the other eye in higher perception/cognition, even when binocular fusion has occurred. The data are strikingly similar across the two very different orthographies. Asynchronies, in which one eye begins the fixation earlier and/or ends it later, occur most frequently in the hemifield corresponding to that eye. We propose that such small asynchronies cue higher processing to prioritize the input from that eye, during and after binocular fusion.

我们调查了在阅读英文和中文时两只眼睛注视之间的小的时间不一致。我们定义了九种不同的异步模式，并报告它们在文本屏幕上的空间分布。我们根据它们对眼睛患病率的影响来解释它们——在更高的感知/认知中，优先考虑来自一只眼睛的输入而不是来自另一只眼睛的输入，即使发生了双眼融合。两种截然不同的拼写法的数据惊人地相似。异步，其中一只眼睛较早开始注视和/或较晚结束注视，最常发生在对应于该眼睛的半场中。我们建议，在双眼融合期间和之后，这种小的异步提示更高的处理来优先考虑来自那只眼睛的输入。
