System and methods for testing and/or training a subject's visual perception span and/or speed are provided. More specifically, a method may include testing/training various aspects of the subject's visual perception span/speed through the use of assessments that test the subject's ability to receive and retain information that is flashed in front of them. By using various assessments, an efficient examination may be administered. In accordance with the invention, an individual may be subjected to such a method of testing/training comprising: presenting one or more two-dimensional representations to the subject at a first time; receiving input responses from the subject at a second time; and processing the received input responses to provide a measure of the perception span of the subject; and processing the time between the first time and the second time to provide a measure of the perception speed of the subject.
