Document Summary
Preparing to learn: infants vision improves over the rst few months of life and there are major developments in color vision, focus and acuity. Babies don"t have 20/20 vision until about 6 months. Infants focus best at 8-12 inches away. Infants can not recognize faces until 4 months of age. Infants do not know how to track moving objects until about 6-10 weeks of age. Babies do not develop full depth perception skills until they begin moving around in their environment. Social referencing: baby uses mother"s reaction to determine what to do. Overall, hearing is much better than vision. Locating sounds improves from 4 months to about 18 months. Infants are sensitive to low-pitches and high-pitched frequencies( more so than adults) Evidence suggest that babies respond to sound in the womb. > by the 25th week of pregnancy( 2nd trimester), baby responds to sound. > by the 32nd week of pregnancy(3rd trimester), baby identi es novel sounds.
