Bioelectrical Measurements of Lenses Effect During Esports Training Sessions: Could the Yellow Lenses Enhance Gaming Performance?

The study of neurophysiological processes during esports training is an expanding field of research, with previous studies investigating the effects of colours in enhancing both the performance and gaming experience. In this paper we assessed the effect of wearing yellow lenses during a game session and whether neurophysiological indexes were correlated to the game performance. A group of 68 participants were asked to play in three different conditions: wearing no lenses (NoL), wearing neutral lenses (NeL) and wearing yellow lenses (YL). The attention level, together with the arousal, the emotional valence and the workload were assessed by means of bioelectrical signals. In YL condition, we found the highest correlation between the valence and the gaming score, as well as the lowest (in absolute value) correlation between the workload and the score. The workload showed a near-to-significant decrease from NeL to YL, while the attention level showed a significant increase from NeL to YL and from NoL to YL, but a non-significant difference between NeL and YL. No differences between the conditions were found for arousal and emotions. The results seem to support a slightly positive effect of the yellow lens in improving gaming performance, qualifying them as a potential personal ergonomic tool for use during tournaments.
