Faster Visual Information Processing in Video Gamers Is Associated With EEG Alpha Amplitude Modulation

Area of Science:

• Neuroscience
• Cognitive Psychology
• Human-Computer Interaction

Background:

• Action video gaming is associated with enhanced cognitive functions, particularly attentional control.
• Electrophysiological correlates, such as electroencephalography (EEG) alpha power, may underlie these improvements by reflecting inhibitory processing crucial for attentional control.

Purpose of the Study:

• To investigate differences in EEG alpha power and visual information processing speed among non-video gamers (NVGs), non-action video gamers (NAVGs), and action video gamers (AVGs).
• To determine if EEG alpha power differences account for variations in visual information processing as measured by the theory of visual attention (TVA).

Main Methods:

• Forty male participants were categorized into NVGs, NAVGs, and AVGs.
• A visual short-term memory task was administered with varying stimulus exposure durations while EEG was recorded.
• Behavioral accuracy data were analyzed using TVA algorithms and correlated with EEG alpha power metrics.

Main Results:

• A positive correlation was observed between post-stimulus EEG alpha power attenuation (10-12 Hz) and information processing speed across all participants.
• Action video gamers (AVGs) exhibited significantly larger EEG alpha power attenuations and faster information processing compared to NVGs and NAVGs, with improvements increasing over time on task.

Conclusions:

• EEG alpha power attenuation serves as a potential neural substrate for cognitive enhancements observed in action video gaming.
• These findings suggest that the inhibitory processes reflected by EEG alpha power are critical for the superior visual information processing capabilities of action video gamers.
