14
Q
Choose three theoretical views of motor development. Compare how the three views explain motor development.
A
The developmental systems perspective takes a look at how both biological and environmental systems influence one’s motor development as it changes.
This is also similar to that of the environmental context theory as it questions on how contexts (objects, people, culture, affordances) can have influence on an individual’s personal development. For example the affordances to certain toys may contribute to child’s motor development.
The ecological systems theory also contributes to the idea of the influences of the environment. The way that it is done through this theory is by taking a look at what has a direct effect on the development while also taking a look at indirect influences. The systems that are looked at include of the Microsystem, the mesosystem, the ecosystem, the macrosystem and the chronosystem. This can be applied to motor development depending on the physical activity that is done within the family in which influences motor development (Microsystem).
