Final answer:
The grasp associated with a child using their whole arm to color or draw is the power grasp, emerging around 1-1.5 years. As children develop, their grasp evolves from using large muscle groups to more precise control, eventually leading to a quadruped or tripod grasp by ages 3-4 years. Option 2) power grasp; 1-1.5 years is the correct answer.
Step-by-step explanation:
The grasp associated with a child using their whole arm to color or draw is known as the power grasp. This developmental milestone typically emerges around the age of 1-1.5 years. At this stage in physical development, toddlers are learning to control and coordinate their movements better, but they still rely on larger muscle groups in the shoulder and arm, leading to a more generalized and less refined grip on objects like crayons or markers.
As children grow, their fine motor skills improve, allowing for more complex and precise movements. For example, by approximately 15 months, some toddlers begin using the mature pincer grasp, which involves picking up small objects with the tips of the thumb and forefinger, indicating more dexterity. Then, as they approach ages 3-4 years, the quadrupod grasp or tripod grasp may develop, where they use their fingers more efficiently to hold and manipulate writing tools for drawing and writing activities.
In conclusion, the correct option for the grasp associated with whole-arm movement in coloring or drawing that emerges at 1-1.5 years is the power grasp.
