An edge-simplicity bias in the visual input to young infants

In the lab, young infants prefer to look at simple, high visibility patterns - those with fewer, thicker, high contrast edges. It is unknown whether these preferences could or do manifest on the vast scale of everyday. This dataset contains images that were captured by fitting 1-3 month-old infants with lightweight head cameras, and adults for comparison. The scripts show how to extract variables related to simplicity (i.e., edge sparsity & orientation consistency) and visibility (root mean square contrast & amplitude by spatial frequency), as well as how those variables were used in analysis.

在实验室环境中，低龄婴儿更倾向于注视简洁、高可视性的图案——即边缘更少、线条更粗且对比度更高的图案。目前尚不明确这类视觉偏好是否能够在广袤的日常视觉场景中显现并发挥作用。本数据集收录了通过为1至3个月大的婴儿佩戴轻量化头戴式摄像头所采集的图像，同时纳入成人的对应图像以作为对照。配套脚本详细说明了如何提取与图案简洁性（即边缘稀疏度(edge sparsity)与方向一致性(orientation consistency)）和可视性（即均方根对比度(root mean square contrast)与空间频率(spatial frequency)维度下的振幅）相关的变量，以及如何将这些变量应用于数据分析。
