A device was developed that permits measurement of performance of primates, through the visual modality, before and after application of pulsed ionizing radiation. Two platforms were constructed, each featuring 2 degrees of freedom. One accommodates the primate and provides him with a response stick to counteract disturbances or fly the platform in relation to a horizon displayed by the second platform. The second platform carries a large hollow sphere that encircles the primate and displays the horizon as the borderline of dark and translucent segments. This platform can be moved about two axes intersecting at a common center with those of the first platform. The shock-signal circuitry is variable in its basic parameters and adjusts automatically to the magnitude of the error committed. Author
