Identifications of a deficit by neuropsychological tests
Ideometric approach and psychometric approach are the two methods that are used in the identification of deficits by neuropsychological tests. Ideometric approach is suitable for clinical examinations of individual patients. Psychometric approach is suitable for the assessment of abilities/ aptitudes using quantitative scores. Whereas the first is used in a clinical examination that takes into account the background of the patient, the second is used in an examination of abilities and aptitudes of the patient irrespective of his or her background.
