Visual perception is often not homogenous across the visual field and can vary depending on situational demands. The reasons behind this inhomogeneity are not clear. Here we show that directing attention that is consistent with a western reading habit from left to right, results in a ~32% higher sensitivity to detect transient visual events in the right hemifield. This right visual field advantage was largely reduced in individuals with reading difficulties from developmental dyslexia. Similarly, visual detection became more symmetric in skilled readers, when attention was guided opposite to the reading pattern. Taken together, these findings highlight a higher sensitivity in the right visual field for detecting the onset of sudden visual events that is well accounted for by left hemisphere dominated reading habit.

阅读能力会影响检测右半场视觉事件的优势。

视觉知觉在整个视野中通常是不均匀的，并且可以根据情况要求而变化。这种不均匀性背后的原因尚不清楚。在这里，我们表明，与从左到右的西方阅读习惯相一致的注意力转移，导致在右半场检测短暂视觉事件的灵敏度提高了约32％。患有发展性阅读障碍的阅读困难的人，这种正确的视野优势会大大降低。同样，当注意力与阅读模式相反时，视觉检测在熟练的读者中变得更加对称。综上所述，这些发现强调了在右视野中检测突发视觉事件的敏感性更高，而左半球主导的阅读习惯很好地解释了这种事件。
