The design and application of a data- and methodbase system for the Aachen Aphasia Test.
The basic components of a data- and methodbase system useful for both individual diagnosis and (group-study) research in neuropsychology are described. Such a system enables one to organize, access and evaluate large data-sets of behavioural, neuroradiological and neurological information. The most important component of the system, the data- and methodbase management system, is described in some detail. It operates on databases comprised of Aachen Aphasia Test examinations and standardized CT evaluations as well as on methodbases containing various sets of analysis routines for the psychometric evaluation of (individual) aphasia test results and the evaluation and (graphical) presentation of standardized (individual) CT lesions. Although exemplified for AAT scores the techniques and principles employed are applicable to data- and methodbase systems in general.
