Despite a number of studies, it remains unclear whether male and female human newborns manifest different visual preferences or perceptual abilities. The goal of this project is to determine with greater confidence whether this is the case or not. In particular, we are interested in finding out whether male and female newborns show different spontaneous preferences for human faces vs. inanimate objects, as suggested by various studies, old and new (e.g., Lewis et al. 1966; Connellan et al. 2000).
