How Can We Know What Babies Perceive? Infants first become sensitive at about two months to kinematic, or motion-carried information for distance, as when one surface moves in front of another. At about four months, infants are able to perceive depth via the difference in the optical projections at the two retinas to determine depth,
What Are We Born Knowing? Summary: While it may appear that infants are helpless creatures that only blink, eat, cry and sleep, one researcher says that studies indicate infant brains come equipped with knowledge of “intuitive physics.” What do babies already know? Highlights: Studies show that when babies are born, they’ve already acquired knowledge about
What Is Intersensory Redundancy? Intersensory redundancy refers to spatially coordinated and concurrent presentation of the same information (e.g., rate, rhythm, intensity) across two or more sense modalities. For the auditory and visual modalities, it also entails the temporally synchronous alignment of the bimodal information. How does the environment an infant is in influence perceptual development?
