镜像和倒置文本阅读时眼动控制的调节
Modulation of oculomotor control during reading of mirrored and inverted texts
摘要：
当文本的空间布局偏离典型的显示方式时，阅读过程中的认知过程和视觉过程之间的相互作用可以被探讨。在这项研究中，我们调查了各种眼动措施在阅读文本与实验操纵布局（字明智和字母明智镜像反转文本以及倒置和乱序文本）。虽然典型的发现（例如，较长的平均注视时间，较短的平均扫视长度）在阅读操纵文本相比，正常的文本在早期的工作中被报道，很少有人知道的变化，在词内着陆位置观察到上述文本布局。在这里，我们进行了精确的分析着陆位置，并发现在所谓的发射场效应的实质性变化，除了预期的整体放缓的阅读性能。具体来说，在阅读我们的操纵文本条件与颠倒的字母顺序（对整体阅读方向），我们发现一个减少发射场效应，而在所有其他操纵文本条件，我们观察到增加发射场效应。我们的研究结果清楚地表明，眼神经系统是高度适应时，面对不寻常的阅读条件。
英文摘要：
The interplay between cognitive and oculomotor processes during reading can be explored when the spatial layout of text deviates from the typical display. In this study, we investigate various eye-movement measures during reading of text with experimentally manipulated layout (word-wise and letter-wise mirrored-reversed text as well as inverted and scrambled text). While typical findings (e.g., longer mean fixation times, shorter mean saccades lengths) in reading manipulated texts compared to normal texts were reported in earlier work, little is known about changes of oculomotor targeting observed in within-word landing positions under the above text layouts. Here we carry out precise analyses of landing positions and find substantial changes in the so-called launch-site effect in addition to the expected overall slow-down of reading performance. Specifically, during reading of our manipulated text conditions with reversed letter order (against overall reading direction), we find a reduced launch-site effect, while in all other manipulated text conditions, we observe an increased launch-site effect. Our results clearly indicate that the oculomotor system is highly adaptive when confronted with unusual reading conditions.
