Question

The sequence of motor development amongst children, in arms and hands, is as follows: A. Thumb sucking B. Grasp and Hold C. Picking up object with opposed thumb D. Defensive movements E. Reach and Grasp

• A. E, D, C, B, A
• B. D, A, E, B, C
• C. A, C, D, E, B
• D. B, C, A, D, E

Hint:

Remembering key developmental milestones can help identify the correct sequence in such questions. Always consider the chronological order of motor skills acquisition when faced with similar problems.

Answer 1

The Correct Option is B

Step 1: Concept
Motor development refers to the progression of physical skills and movements that children acquire as they grow. This includes gross motor skills (large muscle movements such as walking or jumping) and fine motor skills (smaller, more precise movements involving fingers and hands).

Step 2: Meaning
The sequence provided describes different stages in the fine motor skill development of a child's arms and hands.

Step 3: Analysis
1. Defensive Movements (D): These are involuntary reflexes that help protect the body from harm. They occur early on, often before 2 months. 2. Reach and Grasp (E): Around 3-4 months, children start reaching for objects and grasping them with their whole hand. 3. Thumb Sucking (A): This is a common behavior that starts around the same time as reach and grasp but can be seen earlier in some infants. 4. Grasp and Hold (B): At about 5-6 months, children develop more controlled grasping actions where they can hold objects for longer periods. 5. Picking up Object with Opposed Thumb (C): This fine motor skill typically emerges around 9-10 months when the child can use their thumb and index finger to pick up small objects. The correct sequence aligns with these developmental milestones, showing a progression from basic reflexes to more complex hand movements.

Step 4: Conclusion
By understanding the typical order of motor development in children's arms and hands, we can see that option B (D, A, E, B, C) accurately represents this sequence. Final Answer: (B)
