MINDS (Mental Information Processing and Neuropsychological Diagnostic System) was developed with the goal of integrating a number of independent and stand-alone test programs that are used in the diagnosis of psychological and neuropsychological health. The system runs under MS-DOS. The shell program integrates subject information with data obtained through the use of the individual test programs. The current test battery comprises tasks on memory, attention, and motor performance; these tasks require the use of additional peripheral response devices, which are controlled via a multiple I/O interface card. Questionnaires are also included; they have been developed with the author language shell program MicroCAT. MINDS is programmed to allow easy integration of new tests. As an example, the Motor Planning Test is described. The equivalence of the computerized questionnaires with existing tests is also discussed.
