Document Summary

Fine: palmer: full hand, intermediate: use of fingers for smaller objects, pincer: rare (thumb and finger) Crawling position but lack skill of alternate extension of arms and legs. Can"t walk lack of perception (moving walls experiment) Visual cue of crawling on floor is blocked by tray feet movement to brain. Important to use muscles than to be in a position to walk. 4 months understand solids (solid through solid?) Better to see real 3d objects than tv. <6 months easier if objects are moving/real. >6 months can infer object properties and depth from picture. 7 months use visual cues for depth. 4-6 months = specialized combo hand, mouth, vision. After 6 months = hand movements to detect info about object (ex. More cross-modal perception, better than unimodal stimulation. Sensitive to distortions in sound track (rattle shaking faster or slower than sound)
