Cancellation tests are designed to measure sustained and selective attention.
Numerous variations of cancellation tests have been developed to assess sustained, selective attention and spatial inattention following hemispheric lesions. The patient is typically required to scan through an array of stimuli and find (cancel) specific target stimuli (e.g., bells).
There is relatively little normative data for cancellation tests, and most comparative studies show that normal individuals make few, if any, errors (Weintraub 2000). Standardized versions of cancellation tests, such as the Ruff 2 & 7, show good test-retest reliability. In addition, on the Ruff 2 & 7, younger adults performed better than older adults, and performances improved with higher levels of education. There were no gender effects (Mitrushina et al. 2005).
Cancellation tests have been shown to be sensitive in detecting deficits in...
