Abstract

Previous research on the use of peripheral vision to identify two spatially separated stimuli simultaneously has led to the conclusion that the focus of attention has the form of a symmetric ellipse with a broader expansion along the horizontal compared to the vertical meridian. However, research on pseudoneglect has indicated that attention is not symmetrically distributed to the whole visual field. Here, we test if the attention window is indeed symmetrical with regard to its shape and resolution during peripheral vision. The results indicate that the position of those stimuli relative to the focus of attention influences the ability to identify a given set of stimuli. Specifically, stimuli presented to the left and top of the fixation point were more frequently identified correctly compared to those presented to the right bottom. That is, the attention window is rather not symmetric, which must be considered in future studies on the nature of the focus of attention.

周边视觉的注意不对称。
以往关于利用周边视觉同时识别两个空间上分离的刺激物的研究得出的结论是,注意焦点呈对称椭圆形,沿水平经线的扩展范围大于垂直经线。然而,对假性近视的研究表明,注意力并不是对称地分布在整个视野中。在此,我们测试了在周边视觉时,注意力窗口的形状和分辨率是否真的对称。结果表明,这些刺激物相对于注意力焦点的位置会影响识别一组特定刺激物的能力。具体来说,与右下方的刺激物相比,定点左侧和上方的刺激物更容易被正确识别。也就是说,注意窗口并不是对称的,这一点在今后有关注意焦点性质的研究中必须加以考虑。
