Document Summary

Assumptions underlying motor development: postural, manual, motor skills- not pro cient the rst time as media may suggest- in an invariant sequence, onset ages are a good estimate, little variability between cultures. Assumption that it is a brain maturation and physical maturation and with basic experience they will vary at the same time (compared to other people) Western infants are the norm this is the problem: others are precocious (advanced) or delayed- compared to western standards. Motor development milestones: invariant sequence, linear progression, emphasis on onset age. Stability of a skill, the ef cency that the child will show, as time progress they will do better than rst time: adaptability. !1: coping with changes- example: slope, te on shoes. The best predictor of pro ciency: experience. Number of days between onset and test. But, what determines experience: nature/nurture stuff. Cross-cultural variability: can help us learn how experience shapes learning!
