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.
