The Development of Infant Visual Acuity...and Robots?

Here's a USA Today review article of an intriguing child development study about infant visual acuity. I find this study puzzling because the ability of infants and toddlers to "track" moving objects (whether they look like people or not) is something that they naturally develop as they move from the sensorimotor cognitive stage to the preoperational stage. If anything, this research give credence to the connection humans have with each other as interactive objectives because of our characteristics. If an object (like a robot) bears human characteristics, people (especially very young, impressionable ones) may find themselves developing an affinity toward them.
