Measuring right-hemisphere dysfunction in children: validity of two new computer tests

The validity of two new computer-mediated tests for the detection of right-cerebral hemisphere lesions in children--the Right-hemisphere Dysfunction Test and the Visual Perception Test--was evaluated. Normative data were drawn from a group of 91 children (aged five to 14 years) and 14 young adults. The tests were also administered to 14 children with acquired lesions of either right- or left-cerebral hemisphere. The results demonstrate that the Right-hemisphere Dysfunction Test and the Visual Perception Test, with predictive values of 71 per cent and 88 per cent, respectively, are useful in clinical practice for detection of right-hemisphere dysfunction in children.
