The relation of the Archimedes spiral aftereffect and the Trail Making Test to brain damage in children.

Abstract

The spiral aftereffect test and the trail making test were administered to a group of normal children, a group of emotionally disturbed children, and a group of children suffering from cortical damage. These two tests, used separately in unrelated studies, had previously been found to differentiate between adults with and without organic brain damage. In the present study both tests were found to reveal significant differences among the groups, as predicted, and both appear to possess considerable promise as valid methods for assessing cortical impairment.
