Gamers with Internet gaming disorder (IGD) dynamically regulate their psychophysiological responses during playing; however, analyzing instantaneous psychophysiological responses in these gamers has been limited by a lack of appropriate methods. We propose combining the Complementary Ensemble Empirical Mode Decomposition and Direct Quadrature methods to overcome this limitation. The related effect of abdominal breathing (AB) training (as a relaxing psychology method) on the distribution of instantaneous frequency (IF) was investigated by calculating median (IF), kurtosis (IF) and skewness (IF), and 19 participants with high-risk IGD (HIGD) were found to have increased IF [massively multiplayer online role-playing game (MMORPG): 0.36 ± 0.08; first-person shooter game (FPSG): 0.34 ± 0.08] but decreased IF (MMORPG: 5.98 ± 2.31; FPSG: 6.84 ± 4.61) and IF (MMORPG: 0.40 ± 0.69; FPSG: 0.64 ±1.04) during game-film stimuli compared with baseline and recovery states. After AB training, IF of these 19 participants (MMORPG: 0.24 ± 0.11; FPSG: 0.18 ± 0.06) decreased significantly. This study is firstly to observe the IF distribution of respiratory signal in gamers with HIGD; thus, this distribution may be used as a respiratory physiological marker of IGD risk.
患有网络游戏障碍（IGD）的玩家在游戏过程中会动态调节其心理生理反应；然而，由于缺乏合适的方法，对这些玩家瞬时心理生理反应的分析一直受到限制。我们建议结合互补总体经验模态分解和直接正交方法来克服这一限制。通过计算中位数（IF）、峰度（IF）和偏度（IF），研究了腹式呼吸（AB）训练（作为一种放松心理的方法）对瞬时频率（IF）分布的相关影响，发现19名高风险IGD（HIGD）参与者的IF有所增加[大型多人在线角色扮演游戏（MMORPG）：0.36±0.08；第一人称射击游戏（FPSG）：0.34±0.08]，但在游戏电影刺激期间，与基线和恢复状态相比，IF（MMORPG：5.98±2.31；FPSG：6.84±4.61）和IF（MMORPG：0.40±0.69；FPSG：0.64±1.04）有所下降。经过AB训练后，这19名参与者的IF（MMORPG：0.24±0.11；FPSG：0.18±0.06）显著下降。本研究首次观察了HIGD玩家呼吸信号的IF分布；因此，这种分布可能用作IGD风险的呼吸生理标志物。
