A clinic nurse is providing education to new parents about the sequence of expected motor skill progression during early childhood development. Place the following fine motor milestones in the chronological order in which they are typically achieved. Arrange the items from the earliest acquired skill to the latest.
- 1Maintains hands predominantly closed in a tight fist.
- 2Brings both hands together at the midline of the body.
- 3Transfers an object seamlessly from one hand to the other.
- 4Utilizes a crude pincer grasp to pick up small items.
- 5Attempts to construct a small tower using two building blocks.
Cevap
The correct chronological sequence of fine motor milestone acquisition is: maintaining hands closed in a fist (1 month), bringing hands to the midline (3-4 months), transferring objects between hands (7 months), utilizing a crude pincer grasp (9 months), and finally constructing a tower of two blocks (12-15 months).
Fine motor development progresses in a predictable proximodistal pattern (from the center of the body outward to the fingertips). The infant begins with involuntary reflexes (fists closed at 1 month), progresses to bilateral midline play (3-4 months), develops unilateral voluntary control to transfer objects (7 months), refines finger dexterity to a pincer grasp (9 months), and finally achieves the precision and deliberate release required to stack blocks (12-15 months).
