Document Summary
Perception mother"s milk imitate actiosn of other humans but not objects. Smell- babies turned head towards pad with mother"s milk, not other. Hearing- crying when other infants cry, due to distress response. Will not begin to cry when hearing a recording of their own crying. By age 6 months, have full adult level auditory function. Visual acuity- ability to distinguish differences among shapes, patterns, and colors. Reach adult acuity around 1 year old. Poor for distance objects when first born. Respond to high-contrast patterns increased development of visual cortex, development of cones in retina, practice allow for increased development. Preferential-looking technique- researcher shows an infant two things, if infant looks longer at something, then they are more interested by it. Older infants that kicked fasted when ribbon not attached, showed increased memory retention regarding connection between ankle kicking and mobile movement infantile amnesia- inability to remember before the age of 3-4 years.
