Abstract:
The central visual field is essential for activities like reading and face recognition. However, the impact of peripheral vision loss on daily activities is profound. While the importance of central vision is well established, the contribution of peripheral vision to spatial attention is less clear. In this study, we introduced a \"mouse-eye\" method as an alternative to traditional gaze-contingent eye tracking. We found that even in tasks requiring central vision, peripheral vision contributes to implicit attentional learning. Participants searched for a T among Ls, with the T appearing more often in one visual quadrant. Earlier studies showed that participants\' awareness of the T location probability was not essential for their ability to learn. When we limited the visible area around the mouse cursor, only participants aware of the target\'s location probability showed learning; those unaware did not. Adding placeholders in the periphery did not restore implicit attentional learning. A control experiment showed that when participants were allowed to see all items while searching and moving the mouse to reveal the target\'s color, both aware and unaware participants acquired location probability learning. Our results underscore the importance of peripheral vision in implicitly guided attention. Without peripheral vision, only explicit, but not implicit, attentional learning prevails.
摘要:
中央视野对于阅读和面部识别等活动至关重要。然而,周围视力丧失对日常活动的影响是深远的。虽然中央愿景的重要性已经确立,周边视觉对空间注意力的贡献不太清楚。在这项研究中,我们引入了一种“鼠标眼”方法,作为传统凝视视跟踪的替代方法。我们发现即使在需要中央视觉的任务中,周边视觉有助于内隐注意学习。参与者在Ls中搜索T,T更频繁地出现在一个视觉象限中。早期的研究表明,参与者对T位置概率的认识对他们的学习能力并不重要。当我们限制鼠标光标周围的可见区域时,只有参与者知道目标的位置概率显示学习;那些不知道没有。在外围添加占位符并不能恢复内隐注意学习。一项对照实验表明,当参与者被允许在搜索和移动鼠标以显示目标颜色的同时查看所有项目时,有意识和无意识的参与者都获得了位置概率学习。我们的结果强调了周边视觉在隐性引导注意力中的重要性。没有周边视觉,只有明确的,但不是隐含的,注意学习盛行。
