Experimental psychological research on infants' perceptual development using illusory figures

在本研究中，我们使用各种视觉图像对婴儿的知觉发展进行了实验。在第一年，我们调查了婴儿的1）扩张和收缩运动的知觉不对称性，2）非模态完成和3）知觉透明度，并显示了什么年龄的婴儿可以识别每一个知觉线索。我们的扩展和收缩工作的结果发表在国际期刊《婴儿行为与发展》上，非模态工作发表在《知觉》上，透明工作发表在《知觉》上。在本研究项目的第二年，我们使用项目成员之一的北冈制作的刺激，调查了1）运动透明度和2）颜色感应的知觉发展。我们将这些结果发表在国际期刊《感知》和《婴幼儿发展》上。本研究在2008年3月本研究项目结束前，进行了1）婴儿对运动刺激的颜色知觉，2）婴儿对运动信息的图形整合和3）图形深度线索的知觉发展的研究。这些研究的论文将发表在国际期刊《婴儿行为与发展》、《实验心理学与视觉研究》上。

In this research, we conducted experiments on infants' perceptual development using various kinds of visual images. In first year, we investigated 1) perceptual asymmetry of expansion and contraction motion, 2) amodal completion and 3) perceptual transparency in infants and showed what age of infants can recognize each perceptual cue. We published the result of expansion and contraction works in the international journal of Infant Behaviour and Development, amodal one in Perception and transparency one in Perception, too. In second year of this research project, we investigated perceptual development of 1) motion transparency and 2) color induction using the stimuli made by one of project member, Kitaoka. We published these results in the international journals of Perception and Infant and Child Development. And we progressed the researches of 1) perception of color from motion stimuli in infants, 2) figure integration from motion information in infants and 3) perceptual development of pictorial depth cue until the end of this research project term, March 2008. Papers of these researches will appear in the international journal of Infant Behaviour and Development, Journal of Experimental Psychology and Vision Research.
