Describe early motor skill development by focusing on the topics of grasping and handedness
What will be an ideal response?
Grasping requires the infant to coordinate movements of individual fingers to grab an object. Most 4 month olds use their fingers to hold objects. At 7 or 8 months, infants use their thumbs to hold objects. By 12 months old, babies can adjust their hand's orientation and the number of fingers they use to grasp an object. Handedness describes how many or which hands are used to grasp objects. At 4 months old, infants use both hands to grab for objects. At about 5 to 6 months, infants can coordinate the motions of their hands so that each hand performs different actions that serve a common goal. By 12 months of age, children reach for most objects with one hand.
