Visual symmetry perception and symmetry preference have been studied extensively. However, less is known about how people spontaneously scan symmetrical stimuli with their eyes. We thus examined spontaneous saccadic eye movements when participants (N = 20) observed patterns with horizontal or vertical mirror reflection. We found that participants tend to make saccades along the axis of reflection and that this oculomotor behaviour was similar during objective classification and subjective evaluation tasks. The axis-scanning behaviour generates a dynamic sequence of novel symmetrical images from a single static stimulus. This could aid symmetry perception and evaluation by enhancing the neural response to symmetry.

在分类和评估任务中,视觉对称性的自发眼部扫描是相似的
视觉对称感知和对称偏好已被广泛研究。然而,人们如何自发地用眼睛扫描对称刺激却知之甚少。因此,当参与者( N = 20)观察水平或垂直镜面反射的图案时,我们检查了自发的眼跳运动。我们发现参与者倾向于沿着反射轴进行扫视,并且这种动眼行为在客观分类和主观评估任务中是相似的。轴扫描行为从单个静态刺激生成新颖对称图像的动态序列。这可以通过增强对对称性的神经反应来帮助对称性感知和评估。
