The clock drawing test is used to screen which cognitive domains?

• A. Visuospatial and executive function
• B. Memory and language
• C. Attention and processing speed
• D. Social cognition

Answer: (A)

Visuospatial abilities and executive function are what the clock drawing test mainly screens. When asked to draw a clock, you must mentally picture the circle and the placement of numbers around it, then plan and execute placing the hands to show the requested time. This blends visuospatial construction—transforming a mental image into a precise drawing—with executive skills like planning, sequencing, and monitoring for errors. Deficits often show up as a distorted circle, misplaced or clustered numbers, or incorrect hand placement, reflecting difficulties in spatial representation and strategic organization. The test is not primarily a measure of memory or language, since it doesn’t require recalling words or facts. It also isn’t a direct test of attention or processing speed, though those can influence performance, nor does it assess social cognition.
