Document Summary

Hypothesized- result of genetic plan or maturation. New understandings and theories: dynamic systems view. Explains assembly of motor behaviors for perceiving and acting. Infants are motivated to act by something they perceive. Must use perceptions to achieve that goal: mastering a skill. Adaptation through modification of movement: reflexes: built-in reactions to stimuli. Some reflexes are incorporated into more complex voluntary actions. Rooting reflex: when infant"s cheek is stroked, turn their head toward the side being stroked. Sucking reflex: newborns suck on anything put in their mouth. Moro reflex: startle response to sudden, intense noise or movement; arch back, throw head back, fling out arms and legs and then return back to original position. Grasping reflex: infants grasp anything in their palm. Gross motor development- skills that involve large-muscle activities. Qualitative: over time, adapt to more effective patterns. Individual: rate of change differs based on body characteristics and environmental situations. Cumulative: developmental change built upon previous capabilities;
