“…First, vision is coarse in early childhood, with temporal and spatial perception developing up to the age of seven (Ellemberg, Lewis, Liu, & Maurer, ; Farzin, Rivera, & Whitney, , ). Second, although holistic perception of faces (presumably a related process; Nakato et al, ) is at least in place at the age of six (Markham & Adams, ), perception of global visual features develops gradually throughout childhood (Dukette & Stiles, ; Harrison & Stiles, ; Narasimhan & Giaschi, ; Parrish, Giaschi, Boden, & Dougherty, ), even into adulthood (Scherf, Berhmann, Kimchi, & Luna, ), and processing of eye gaze develops at least until the age of 11 (Mareschal et al, ). Testing ages 7–15 thus allowed us to measure emergent gaze perception during a potentially sensitive developmental window among children whose more basic visual mechanisms were presumably in place.…”
