Document Summary

*motor development: the progressive change in motor behavior through the lifespan. 2, 8, 10, 30, etc. ) are studied at once. This is how study usually goes because it is cheaper and you can see different factors of different age groups. *longitudinal study: measures 1 group over the course of many years (10, 20, 30, lifetime). This takes obviously, a long time to get all the data, it is very expensive, participants may drop out or die. Changes in observable motor performance in the first two years. Develop motor skills from head down in that: proximodorsal principle: axis-outward. Posture: 3 main stages: head control, sitting, standing. Gets to sitting pulls to standing stands alone. *special populations: down syndrome: takes 2 years to walk unsupported, low intelligence quotients: takes at least 1 year to walk. *critical period: the time when a child is most sensitive to learning a skill.
