A visual enhancement training program utilizing the Eyespan was evaluated for its effect on the P-300 latency. The P-300 latency is a cortical response occuring appoximately 300 ms. after a stimulus is presented. The latency of 16 subjects was measured under identical conditions before and after a training program. Eight subjects participated in three weeks of training involving 16 five minute sessions with the Eyespan. The other eight subjects served as control for the study. After the training program, results showed an insignificant change in latency of the experimental group, while the control group showed an increase in latency.
