Motor Development Lecture

Question 1

What are the newborn reflexes

Answer 1

• Rooting/ sucking
• Palmar (hand grasp)
• Newborn stepping -Declines at 2 mos bc they’re growing & getting heavy
• Babinski Reflex= Lasts 2 yrs of age (curling toes when feet are touched)

Question 2

What is Cephalocaudal Progression?

Answer 2

-Development starts from head to toe

Question 13

What does the degree of Motor Development depend on?

Answer 13

• Culture

- Movement is discouraged in dangerous placesvs encouraged in safe places

Question 14

What is the Neurlogical Maturation theory?

Answer 14

• Emerging milestones relfect a natural unfolding of biological plan
• Disappearence of newborn reflexes are attributed to cortical maturation, inhibition of primitive reflex actions

Question 15

What is the Dynamic systems approach?

Answer 15

• Emphasized confluence of many factors= emerge of new motor skills including neural mechs, increases in strength/posture/balance/perception skills/motivation
• Both internal & external factors (gravity)

Question 16

What is the process of Variation & Selection?

Answer 16

• Change occurs through mechs of variation & selection
• Variation= strategies
• Selection= most efficient/ effective strategies for certain situations
• Each infant has to learn from epxerience for EVERY SINGLE motor skills they master
