Individuals can vary widely in their experience of color. Whether these differences are more closely tied to innate differences in the brain or to experience and learning remains actively debated. Recent studies in adults show systematic biases in the perception of blues and yellows and also striking differences in how they perceive these colors in images. This project will use behavioral measurements to examine whether these perceptual differences are also present in infants, and explore the potential role of development and experience in color perception. The research will be conducted at Chuo University in Japan in collaboration with Dr. Masami Yamaguchi, a noted expert in infant perception. With the paradigms designed in Japan, data will also be collected in the United States to explore cross-cultural factors. The results of this project will help reveal how both visual sensitivity and color appearance are shaped by experience and the timescales of these effects.Human observers show a reduced sensitivity to blue and yellow compared to other hues. This sensitivity bias is postulated to represent an adaptation to the natural environment, which varies predominantly in blue and yellow. Individuals also show ?higher-order? differences in how they experience blue and yellow, with the bluish tints more likely to be attributed to the lighting than the object. This may again reflect a learned property of the world (e.g. that shadows tend to be bluish). Little is known about how these effects develop, and this project will explore this development by testing for parallel color biases in infants. At Dr. Masami Yamaguchi's lab, preferential looking techniques are used to investigate the color perception of infants, and this project will use this technique to evaluate color sensitivity and appearance in infant observers. Results from infants and adults in the United States and Japan will be compared to inform whether the blue-yellow axis asymmetry is also influenced by the observer?s specific visual environment.This award under the East Asia and Pacific Summer Institutes program supports summer research by a U.S. graduate student and is jointly funded by NSF and the Japan Society for the Promotion of Science.

每个人对颜色的体验都有很大的不同。这些差异是否与大脑的先天差异或经验和学习更密切相关，仍然存在积极的争论。最近对成年人的研究表明，他们对蓝色和黄色的感知存在系统性偏见，而且他们在图像中感知这些颜色的方式也存在显着差异。 这个项目将使用行为测量来检查这些感知差异是否也存在于婴儿中，并探索发展和经验在颜色感知中的潜在作用。这项研究将在日本中央大学与婴儿感知领域的著名专家山口雅美博士合作进行。在日本设计的范例中，也将在美国收集数据，以探讨跨文化因素。这个项目的结果将有助于揭示视觉敏感度和颜色外观是如何通过经验和这些影响的时间尺度来塑造的。人类观察者对蓝色和黄色的敏感度比其他色调要低。这种敏感性偏差被认为是对自然环境的适应，主要是蓝色和黄色。个人也表现出？更高阶？他们感受蓝色和黄色的方式存在差异，蓝色的色调更可能归因于照明而不是物体。这可能再次反映了世界的一个习得属性（例如，阴影往往是蓝色的）。人们对这些影响是如何发展的知之甚少，本项目将通过测试婴儿的平行颜色偏差来探索这种发展。在Masami Yamaguchi博士的实验室，优先观察技术被用于研究婴儿的颜色感知，本项目将使用该技术来评估婴儿观察者的颜色敏感度和外观。将比较来自美国和日本的婴儿和成人的结果，以了解蓝黄轴不对称是否也受到观察者的影响？该奖项是由美国国家科学基金会（NSF）和日本科学促进会（Japan Society for the Promotion of Science）共同资助的，旨在支持美国研究生的暑期研究。
