Attention difficulties are common after neurological injury and can affect how a person scans information, stays focused, and completes everyday tasks. In adult rehabilitation settings, printable worksheets are often used to provide structured cognitive practice in a format that is easy to understand, low-prep, and repeatable.
This page covers the Star Cancellation Test — a well-known screening instrument — and the shape cancellation worksheets that borrow its format for structured practice. You can download a free shape cancellation worksheet below, learn how the task works, and see how graded versions are typically used.

What is a shape cancellation task?
A shape cancellation task is a visual attention activity in which the person scans a page filled with shapes and marks only the target shape while ignoring distractors. This type of task can be used to challenge sustained attention, selective attention, visual scanning, and processing speed in an adult-appropriate worksheet format. In some settings, completion time and error counts are also recorded for added structure.
The task may look simple at first, but it becomes meaningfully more challenging depending on the number of shapes on the page, the similarity between target and distractor shapes, the visual density of the worksheet, and whether the task is timed. That flexibility is one reason cancellation worksheets are commonly used in clinical, educational, and home practice settings.
The Star Cancellation Test
The worksheet format is based on the Star Cancellation Test, a paper-and-pencil screening test for unilateral spatial neglect, most often used after stroke or other brain injury. In practical terms, it checks whether a person is missing information on one side of space when scanning a page.
In the test, the person is asked to cross out the small stars on a page while ignoring other distractors. One commonly cited version includes 56 small stars mixed with 52 large stars, 13 letters, and 10 short words. Missing more items on one side of the page can suggest spatial neglect. To learn more, see the Stroke Engine assessment page, which also hosts a copy of the test.
Worth knowing: printable shape cancellation worksheets used for practice are not the same as the standardized Star Cancellation Test. The worksheets on this page are structured cognitive practice materials — they are not assessment, diagnostic, or treatment tools.
Grading: from simple to complex
In practice, attention tasks are often most useful when they are graded rather than one-off. With shape cancellation tasks, grading typically involves:
- fewer or more shapes on the page
- minimal versus increased distractors
- consistent versus varied shape sizes
- lower versus higher visual density
- untimed versus timed completion
This allows the task to better match the individual's needs, tolerance, and current level of performance — starting simple and building up, rather than jumping straight to the hardest version.
Who uses shape cancellation worksheets
- Occupational therapists and speech-language professionals
- Rehabilitation and community programs
- Educators working with adult learners
- Caregivers supporting cognitive practice at home
- Adults looking for structured, printable cognitive activities
All of our worksheets are designed to be adult-appropriate, visually clean, and easy to understand without unnecessary visual clutter.
The free worksheet above is a single sample. If you want the full graded progression, our Shape Cancellation set includes 30 worksheets across basic, moderate, and complex levels — the basic pages use fewer shapes and minimal distractors, and the complex pages use denser layouts with greater variability and time challenge.
