The visual, cognitive, and coordination skills of a subject may be tested and/or trained by providing a variety of stimuli to a subject. Responses may be received from a subject, the appropriateness of which may depend upon the combination of stimuli provided to the subject. A touch screen display device may be used both to provide stimuli and to receive responses from a subject. Any number and type of output devices and input devices to receive responses may be used. Behavioral information and other data regarding the performance of a subject may be recorded. Scoring may be based upon the speed, accuracy, and other aspects of the performance of a subject.
