Neurogaming with motion-onset visual evoked potentials (mVEPs): adults versus teenagers.

Motion-onset visually evoked potentials (mVEPs) are neural potentials that are time-locked to the onset of motion of evoking stimuli. Due to their visually elegant properties, mVEP stimuli may be suited to video game control given gaming's inherent demand on the users' visual attention and the requirement to process rapidly changing visual information. Here, we investigate mVEPs associated with 5 different stimuli to control the position of a car in a visually rich 3D racing game in a group of 15 BCI naïve teenagers and compared to 19 BCI naive adults. Results from an additional 14 BCI experienced adults were compared to BCI naïve adults. Our results demonstrate that game control accuracy is related to the number of trials used to make a decision on the users' chosen button/stimulus (76%, 62% and 35% for 5, 3 and 1 trials, respectively) and information transfer rate (ITR) (13.4, 13.9 and 6.6 bits per minute (BPM)), although, even though accuracy decreases when using three compared to the commonly used five trial repetitions, ITR is maintained. A Kruskal-Wallis test suggests that BCI naïve adults do not outperform BCI naïve teenagers in the 3D racing game in the first and seconds laps (p>0.05), but do outperform in the third lap (p<0.05). A comparison between BCI naïve and BCI experienced adults indicates BCI experienced adults do not perform better than BCI naïve adults (p>0.05).
