Define the term - lateralisation and localisation
Discriminative validity studies including lateralisation and localisation achieved satisfactory results, but the localisation studies were based on small samples. Quantitative indices from the Luria-Nebraska were found to correlate significantly with CT scan quantitative indices in alcoholic and schizophrenic samples. There have been several studies of specific neurological disorders including multiple sclerosis, alcoholism, Huntington's disease, and learning disability, all with satisfactory results in terms of discrimination.
