Document Summary
Vision: blurry, but by three months can perceive all color. Hearing: by six months can localize sound in a dark room, and if the sound is in reaching distance they will reach for it. Premise: infants prefer novel stimuli over familiar stimuli. As the stimulus becomes familiar, they lose interest and they habituate . Study: test of color - can they tell the difference between colors? (will they habituate to the color red and then react to yellow?) Edges (boundaries of objects) can be perceived at three months of age. Showed that locomoting (crawling) infants won"t go to the deep side". Two month old non-locomoting infants will show a deceleration (decrease) in their heart rate, which indicates an interest to the deep side". Locomoting infants will show an increase in heart rate, indicating anxiety when they look towards the deep side". Children are naturally curious (non-regulatory drive) and develop schemes . Schemes - structures for perceiving and processing the world.
