The invention, named Test Administration Platform (TAP), comprises a software language and method and means for the development and administration of tests based on an open-source proprietary programming language, and for the storage of these test results in a searchable and exportable database. While intended initially for use in the field of neuropsychology, the invention has utility in many fields, particularly in research fields in which intermediate data might be useful. The invention can also be used to store free-form data, such as interview notes and demographic data. All data within the invention is organized by subject. Tests utilizing the invention can be administered on personal computer and personal digital assistant (PDA) platforms, and can use one or two displays. The invention provides that tests created with the invention and data created during administration of the tests can synchronize and backup to a central server using wireless or wired networking technologies, and can take advantage of text-to-speech, audio recording and tablet/touch-screen recording technologies.

The invention comprises a neuropsychological test method designed to measure a test subject's variables of visual attention for stimuli believed to preferentially elicit specific visual pathways. Target visual pathways include the magnocellular on/off, parvocellular chromatic red/green, koniocellular blue/yellow, and parvocellular achromatic pathways. Furthermore, the invention computes differential measures between the different stimuli types for diagnostic value. These computations include, but are not limited to, measures believed to elicit non-linear contrast gain control, on versus off pathways, and changes in performance over time. The test displays both target and noise (non-target) stimuli with different apriori probabilities at different stages of the test. The test can capture and analyze physiological measures, isoluminant points and critical flicker fusion points. In accordance with the present invention, a novel method and system called the “Variable Contrast Continuous Performance Test (VC-CPT)” is provided.
