Baby Blur: Infants’ Eyes Take Longer to Process Movement
LiveScience:
Rapidly changing images may look like a blur to infants, according to a new study. Although babies can see the movement, they may not be able to identify the individual elements within a moving scene as well as an adult can.
Babies’ brains gradually develop the ability to use visual information to discover and process their world. Researchers found that the speed limit at which babies can recognize individual moment-to-moment changes is about half a second.
That’s about 10 times slower than for adults, who can recognize rapid, individual changes that occur 50 to 70 milliseconds or slower.
“Their visual experience of changes around them is definitely different from that of an adult,” study researcher Faraz Farzin said in a statement. (Farzin, who conducted the work as a graduate student at UC Davis, is now a postdoctoral fellow at Stanford University.)
