我们使用基本的视觉任务检查了左右两个视觉半球之间和内部的相互作用。每个实验要求在注视时识别一个字母，然后辨别(实验I)或检测(实验2)周边Gabor目标的方向。在一半的试验中，Gabor牵引物出现在Gabor靶区之间，或者被限制在一侧半视野(单侧条件)，或者跨越左右半视野(双侧条件)。只有在干扰因素存在的情况下，方位辨别和检测才显示出双边优势。结果证实，即使在这些最基本的视觉任务上，注意选择也具有双边优势。(C)2009爱思唯尔有限公司。保留所有权利。
We examined interactions between and within the left and right visual hemifields using elementary visual tasks. Each trial required identifying a letter at fixation and then either discriminating the orientation of (experiment I) or detecting (experiment 2) peripheral Gabor targets. On half the trials Gabor distracters were presented between the Gabor targets, and were either restricted to one lateral hemifield (unilateral condition) or presented across the left and right hemifields (bilateral condition). Orientation discrimination and detection each exhibited bilateral superiority only when distracters were present. The results confirm bilateral superiority in attentional selection, even on these most elementary visual tasks. (C) 2009 Elsevier Ltd. All rights reserved.
