Rooting Reflex: Newborn’s mouth moves towards brush on cheek
Grasp Reflex: Newborn’s grab on to anything in their hand (E.G finger in hand)

Question 3

“Theories of motor development”
Maturational Account

Answer 3

Motor development depends on the DEVELOPMENT OF THE BRAIN’S MOTOR.

(E.G study (1929) on learning to climb stairs with twins. Found out that both were able to walk up the stairs, despite the study. It should that within a year (52 weeks) they were developmental ready.

Question 4

Maturational Account Part 2

Answer 4

Motor deprivation doesn’t lead to motor impairment
- babies with less motor experience sill DEVELOP NORMALLY
(E.g Indians carrying babies on their backs)
- In some cause, ONLY extreme motor deprivation; (E.g having babies only in cribs)

Question 5

Dynamic systems theory

Answer 5

Emphasizes that it is the interaction between the person, environment, and the task that changes how our movement.
- Brain system
- Body
- Perception
- Environment

Question 6

The Mystery of the Disappearing Step Reflex

Maturation theory or dynamic System theory ?

Answer 6

dynamic System theory ?

Question 7

Support for Dynamic Systems theory

Answer 7

The Step Reflex
- babies are born with a stepping reflex that disappears within weeks of birth.
One- month-old infants. ( who don’t have the step reflex will step in water
-babies still have the kick reflex

Question 8
