THE PURPOSE OF THIS EFFORT IS TO DETERMINE THE FEASIBILITY AND UTILITY OF A MICROCOMPUTER-BASED SERIES OF NEUROPSYCHOLOGICAL TESTS THAT INCORPORATE VISUAL, AUDITORY, AND MOTOR SKILLS.

THE PURPOSE OF THIS EFFORT IS TO DETERMINE THE FEASIBILITY AND UTILITY OF A MICROCOMPUTER-BASED SERIES OF NEUROPSYCHOLOGICAL TESTS THAT INCORPORATE VISUAL, AUDITORY, AND MOTOR SKILLS. THE OBJECTIVE IS TO DEVELOP A MICROPROCESSOR HARDWARE SYSTEM THAT: 1.IS RELATIVELY INEXPENSIVE (UNDER $10,000); 2.IS FOUND PLEASANT AND SATISFYING TO INTERACT WITH BY THE PATIENT;3.CAN GENERATE MULTISENSORY STIMULI (VISUAL, AUDITORY);4.CAN GENERATE SOPHISTICATED, GRAPHIC DISPLAYS;5.ALLOWS FOR COMPLEX PATIENT-VISUAL DISPLAY INTERACTIONS SUITABLE FOR ASSESSING PREVIOUSLY TECHNOLOGICALLY UNAVAILABLE PSYCHOLOGICAL ABILITIES (E.G., VISUOPERCEPTUAL CONSTRUCTIONAL 6.IS COMPATIBLE FOR USE WITH AVAILABLE CLINICAL ASSESSMENT PRIMARY CONSIDERATION WILL BE GIVEN TO DEVELOPMENT OF AUTOMATED VERSIONS OF TASKS SIMILAR TO THE FOLLOWING FREQUENTLY USED CLINICAL INSTRUMENTS: TRAILMAKING EMPHASIS WILL BE ON DEVELOPMENT OF A MEANINGFUL, USER-FRIENDLY SYSTEM WITHIN HARDWARE AND SOFTWARE LIMITATIONS OF AN INEXPENSIVE SYSTEM. THE DEVELOPMENT OF GRAPHIC DISPLAYS, MAN-MACHINE INTERFACE, AND SCORING FUNCTIONS SHOULD BE ACCOMPLISHED IN PHASE I. THE EQUIVALENCE BETWEEN THE COMPUTERIZED PROCEDURES AND CURRENT PEN AND PENCIL TECHNIQUES WILL BE ANALYSED. INITIAL DATA FOR ASSESSING THE ABILITY TO DISCRIMINATE AMONG RELEVANT POPULATIONS WILL BE OBTAINED.
