Prior studies have shown that strabismic amblyopes do not exhibit pseudoneglect in visual line bisection, suggesting that the right-hemisphere dominance in the control of spatial attention may depend on a normally developing binocular vision. In this study, we aimed to investigate whether an abnormal binocular childhood experience also affects spatial attention in the haptic modality, thus reflecting a supramodal effect. To this aim, we compared the performance of normally sighted, strabismic and early monocular blind participants in a visual and a haptic line bisection task. In visual line bisection, strabismic individuals tended to err to the right of the veridical midpoint, in contrast with normally sighted participants who showed pseudoneglect. Monocular blind participants exhibited high variability in their visual performance, with a tendency to bisect toward the direction of the functioning eye. In turn, in haptic bisection, all participants consistently erred towards the left of the veridical midpoint. Taken together, our findings support the view that pseudoneglect in the visual and haptic modality relies on different functional and neural mechanisms.

双目视觉在视觉和触觉二分法中驱动假忽略的作用：来自斜视和单眼盲人的证据。

先前的研究表明，斜视性弱视在视线二等分时不会表现出假性忽略，这表明右半球在控制空间注意力方面的优势可能取决于正常发展的双眼视觉。在这项研究中，我们旨在调查异常的双眼童年体验是否也会影响触觉模式的空间注意力，从而反映超模态效应。为此，我们比较了视力正常、斜视和早期单眼盲参与者在视觉和触觉线平分任务中的表现。在视线二等分中，斜视者倾向于在真实中点的右侧犯错，这与表现出假性忽视的正常视力参与者形成鲜明对比。单眼盲参与者在视觉表现上表现出高度可变性，有向功能眼的方向平分的趋势。反过来，在触觉平分中，所有参与者始终错误地朝着真实中点的左侧。总之，我们的研究结果支持视觉和触觉模式中的假性忽略依赖于不同的功能和神经机制的观点。
