The primary objectives of this research program were the development of a battery of tests to investigate the effects of brain impairment on sensory and perceptual functioning. The Sensory-Perceptual Exam (SPE) contains measures intended to evaluate both relatively "pure" sensory functions, as well as those which involve more integrated and complex perceptual activities of higher cortical functioning. The tests thus far incorporated into the standard battery include the following: Spiral Aftereffect, Critical Flicker Fusion, Complex Reaction Time, Memory-for-Designs, Dot Determination, Auditory Pulse Rate Discrimination, Vestibular Perception of Vertical and Proprioceptive Perception of Vertical, Tactile Form Discrimination, and Color-Word Rigidity. Table 1 of the report demonstrates that SPE performance is responsive to degree of cerebral impairment. The data of Table 2 demonstrate the potential usefulness of several of the tests for possible differential diagnostic application. (DB)
