我们使用视觉认知中的一个既定范式，即“注意力瞬脱”，来证明我们的注意力被植物捕获的速度比被动物捕获的速度要慢。这表明视觉系统如何处理植物的根本差异，这可能导致广泛考虑的植物失明。对许多人来说，植物并不像动物那样有趣。学生们通常更喜欢研究动物而不是植物，对植物的记忆更差，植物在课堂上的代表性不足。观察到的对植物缺乏兴趣被描述为植物盲视，这个术语旨在概括忽视环境中植物的倾向和对植物功能作用缺乏认识。虽然植物失明这个术语暗示了植物忽视的感知或注意力成分，但很少有研究探讨植物和动物在感知上是否存在真实的差异。在这里，我们使用一个既定的范式在视觉认知，“注意瞬脱”，比较植物和动物的图像捕获注意力资源的程度。我们发现，参与者能够更好地检测到动物比植物在快速图像序列和视觉注意有不同的不应期时，植物已被检测到。这些结果表明，视觉系统如何处理可能导致植物失明的植物存在根本差异。我们讨论了视觉处理的知觉和生理限制可能会提出有用的策略，特征和克服动物中心主义。
We use an established paradigm in visual cognition, the “attentional blink,” to demonstrate that our attention is captured more slowly by plants than by animals. This suggests fundamental differences in how the visual system processes plants, which may contribute to plant blindness considered broadly. Plants, to many, are simply not as interesting as animals. Students typically prefer to study animals rather than plants and recall plants more poorly, and plants are underrepresented in the classroom. The observed paucity of interest for plants has been described as plant blindness, a term that is meant to encapsulate both the tendency to neglect plants in the environment and the lack of appreciation for plants’ functional roles. While the term plant blindness suggests a perceptual or attentional component to plant neglect, few studies have examined whether there are real differences in how plants and animals are perceived. Here, we use an established paradigm in visual cognition, the “attentional blink,” to compare the extent to which images of plants and animals capture attentional resources. We find that participants are better able to detect animals than plants in rapid image sequences and that visual attention has a different refractory period when a plant has been detected. These results suggest there are fundamental differences in how the visual system processes plants that may contribute to plant blindness. We discuss how perceptual and physiological constraints on visual processing may suggest useful strategies for characterizing and overcoming zoocentrism.
