infant?
a) Skills develop from the center of the body outward.
b) Skills develop from the feet towards the head.
c) Skills develop in a random, unpredictable sequence.
d) Skills develop from the head downward towards the feet.
Answer: D
Explanation: Gross motor development follows a cephalocaudal pattern, meaning infants gain
control of their head and neck first, followed by the trunk, and finally the legs and feet.
2. An infant's fine motor skills, such as reaching and grasping, typically develop in which pattern?
a) From the head to the feet
b) In a symmetrical fashion on both sides of the body
c) From the center of the body outward to the hands and fingers

Answer: C
Explanation: Fine motor development follows a proximodistal pattern, where control progresses
from the shoulder and trunk towards the more distant parts of the limbs, like the hands and
fingers.

object permanence and trial-and-error exploration?
