Document Summary
Babies motor achievements have powerful effect on their social relationships. Chapter 4. 5. 1 the sequence of motor development. Gross-motor development: control actions that help them explore in the environment, such as crawling, standing and walking. Cephalocaudal trend: motor control of the head comes before control of the arms and trunk, which precedes control of the legs. Proximodistal trend: head, trunk and arm control precedes coordination of the hands and fingers. Chapter 4. 5. 2 motor skills as dynamic systems. Ex: control of head + upper chest = sitting with support. While attempting a new skill, previously mastered skills often become less secure: dynamic systems theory shows that motor development cannot be genetically determined. It is motivated by exploration and the desire to master new tasks, hereditary can map it out only at a general level. Rather than being hardwired into he nervous system, behaviours are softly assembled, allowing for different paths to the same motor skill.
