Behavioral Dynamics Between Infants With Visual Loss and Healthy Controls

"A standardized apparatus, scenario, and procedure was applied to record all the behavioral phenotypes with minimized background interference and stimulation.~For each standardized procedure, the guardian sits in the chair, holding the infant facing the stage. Each infant is given a few minutes to adapt to the surroundings and to be calm before recording. No hints or simulations are permitted during the entire process. The recording process lasted for over 5 minutes to ensure that behavioral phenotypes could be completely recorded."
