Abstract
We describe a set of algorithms that enhance the sensitivity of cancellatio n tests used in assessing visuospatial neglect. The algorithms can be readi ly implemented on a computer and can provide temporal and nontemporal data on strategies used during cancellation. We also present preliminary results from a group of 68 right-hemisphere brain-damaged patients and 12 age-matc hed control participants, which demonstrate the clinical significance of th e measures we have defined.
