Abstract

It has been posited that number and space are processed with shared mechanisms. We examined whether the stimulus configuration that leads to the Ebbinghaus size illusion would change numerosity perception. We first prepared visual stimuli with which perceived densities were equated for given dot number and area size (Experiment 1). In the subsequent experiments using the prepared stimuli, two sets of dots were surrounded by two sets of inducers (one consisted of small circles and the other of large circles). Participants reported which area contained the larger number of dots (Experiment 2) and which area where the dots appeared was larger (Experiment 3). The results showed that dots surrounded by the small (large) inducers appeared more (less) numerous and occupied a larger (smaller) spatial extent. These results suggest that visual processes of numerosity interact with those of size perception independent of visual processes for perceived density.

艾宾浩斯错觉改变了独立于密度感知的数量感知

有人假设数字和空间是通过共享机制处理的。我们研究了导致艾宾浩斯大小错觉的刺激配置是否会改变对数字的感知。我们首先准备了视觉刺激，其感知密度与给定的点数和面积大小相等（实验1）。在使用准备好的刺激的后续实验中，两组点被两组诱导物包围（一组由小圆圈组成，另一组由大圆圈组成）。参与者报告哪个区域包含更多的点（实验2），哪个区域出现的点更大（实验3）。结果表明，被小（大）诱导剂包围的点看起来更多（更少），占据更大（更小）的空间范围。这些结果表明，数量的视觉过程与大小感知的视觉过程相互作用，独立于感知密度的视觉过程。

期刊介绍： Vision Research is a journal devoted to the functional aspects of human, vertebrate and invertebrate vision and publishes experimental and observational studies, reviews, and theoretical and computational analyses. Vision Research also publishes clinical studies relevant to normal visual function and basic research relevant to visual dysfunction or its clinical investigation. Functional aspects of vision is interpreted broadly, ranging from molecular and cellular function to perception and behavior. Detailed descriptions are encouraged but enough introductory background should be included for non-specialists. Theoretical and computational papers should give a sense of order to the facts or point to new verifiable observations. Papers dealing with questions in the history of vision science should stress the development of ideas in the field.
