Developmental theories posit that immature cognitive control and excessive reward-seeking capacities may be a risk factor for addictive behaviors during adolescence, but the control and reward capacities have rarely been assessed experimentally in adolescents with Internet gaming disorder (IGD) simultaneously. This electrophysiological study examined inhibitory control and reward processing in adolescents with IGD during a go/no-go task and a gambling task. Behaviorally, the adolescents with IGD exhibited lower inhibitory control, as measured by the accuracy of no-go trials, and more risk seeking, as measured by the proportion of risky choices, than did the controls. Compared with the controls, the adolescents with IGD exhibited decreased no-go P3 and blunted feedback-related negativity (FRN) amplitudes following gains (gain FRN) but not losses. Thus, IGD in adolescents is potentially driven by dysfunction of the control system and the approach system rather than the avoidance system, supporting the neurobiological model of adolescent development.
发展理论假设，不成熟的认知控制和过度的寻求奖励能力可能是青少年成瘾行为的一个风险因素，但在同时具有互联网游戏障碍 (IGD) 的青少年中，很少有实验评估控制和奖励能力。这项电生理学研究在 Go/No-Go 任务和赌博任务中检查了具有 IGD 的青少年的抑制控制和奖励处理。行为上，具有 IGD 的青少年在 Go/No-Go 试验中的准确性较低，表现出较低的抑制控制，并且在风险选择的比例较高，表现出更多的风险寻求，这一比例高于对照组。与对照组相比，具有 IGD 的青少年在获得奖励后（获得 FRN）表现出较低的 No-Go P3 和迟钝的反馈相关负波 (FRN) 幅度，但在损失后则没有。因此，青少年的 IGD 可能是由控制系统和接近系统而不是回避系统的功能障碍驱动的，这支持了青少年发展的神经生物学模型。
