During a community health workshop on early childhood development, a nurse discusses the predictable sequence of fine motor skill acquisition. Arrange the following milestones in the chronological order in which a child is typically expected to achieve them, from earliest to latest.
- 1Fading of the primitive palmar grasp reflex
- 2Development of a voluntary palmar grasp
- 3Ability to transfer an object from one hand to the other
- 4Use of a neat pincer grasp to pick up small objects
- 5Ability to successfully stack two blocks
Cevap
The correct sequence from earliest to latest is: 1) Fading of the primitive palmar grasp reflex, 2) Development of a voluntary palmar grasp, 3) Ability to transfer an object from one hand to the other, 4) Use of a neat pincer grasp, and 5) Ability to successfully stack two blocks.
Fine motor development in infants follows a predictable proximodistal pattern, progressing from gross, uncoordinated movements to refined, specific actions. The primitive grasp reflex must first fade (2-3 months) before voluntary palmar grasping can occur (5 months). As bilateral coordination improves, the infant learns to cross the midline and transfer objects between hands (7 months). Further refinement of the distal digits leads to the neat pincer grasp (10 months). Finally, the ability to precisely release an object allows the child to stack blocks (12-15 months).
