Caption: Duke University neuroscientists Elizabeth Brannon and Ariel Starr test a rudimentary understanding of numbers in infants called a "primitive number sense." When looking at two collections of dots presented on video screens, primitive number sense allows the child to identify which set is larger even without verbal counting or knowing numbers. The length and direction of the child's gaze is used to infer their sense of novelty.
