Drawing ability may be compromised by which impairments affecting which components?

• A. sensory; vision; hearing
• B. cognitive; memory; attention
• C. neural; limbs; depth perception
• D. motor; limbs; visual acuity

Answer: (D)

Drawing relies on two main functions: precise motor control of the hands and arms, and clear visual input to guide movements. When there are motor impairments in the limbs, the ability to produce steady, accurate strokes is directly reduced, making controlled drawing difficult. Visual acuity matters because clear vision is needed to see lines, edges, and proportions accurately; if visual acuity is poor, guiding each stroke and judging the details becomes unreliable. While other domains like sensory processing, memory, or depth perception can influence performance, the combination of limb motor control and visual clarity most directly undermines the act of drawing.
