While the use of social media and online-communication applications has become an integral part of everyday life, some individuals suffer from an excessive, uncontrolled use of social media despite experiencing negative consequences. In accordance with neuropsychological models of addiction, we assume the tendency of a social-networks-use disorder to be related to an interplay of predisposing personality traits (e.g., impulsivity), and reductions in cognitive functions (e.g., executive functions, inhibitory control). The current study makes first strides towards examining this interplay. In addition to a newly developed social-networks-specific auditory Go-NoGo paradigm, other neuropsychological paradigms were used. Impulsivity and social-networks-use-disorder symptoms were assessed by standardized questionnaires. The results show that the symptom severity of a social-networks-use disorder is mainly associated with attentional impulsivity. General executive functions and specific inhibitory control of social-networks-related cues have no direct effect on symptom severity. However, moderated regression analyses emphasize that increased symptom severity is associated with higher attentional impulsivity, especially if there are additionally reductions in executive functions or specific inhibitory control. The results complement previous findings and inform future research on social-networks-use disorder. The findings support the applicability of theoretical models of addictive behaviors to the social-networks-use disorder and point to social-networks-related specificities regarding attention-related facets.
虽然社交媒体和在线通信应用的使用已经成为日常生活的不可或缺的一部分，但一些人尽管经历了负面后果，仍然过度、无法控制地使用社交媒体。根据成瘾的神经心理学模型，我们假设社交网络使用障碍的倾向与易感性人格特质（例如冲动）的相互作用以及认知功能（例如执行功能、抑制控制）的降低有关。目前的研究朝着检验这种相互作用迈出了第一步。除了新开发的社交网络特定的听觉 Go-NoGo 范式外，还使用了其他神经心理学范式。通过标准化问卷评估冲动和社交网络使用障碍症状。结果表明，社交网络使用障碍的症状严重程度主要与注意力冲动有关。一般执行功能和社交网络相关线索的特定抑制控制对症状严重程度没有直接影响。然而，调节回归分析强调，症状严重程度的增加与注意力冲动增加有关，尤其是在执行功能或特定抑制控制进一步降低的情况下。研究结果补充了先前的发现，并为社交网络使用障碍的未来研究提供了信息。研究结果支持成瘾行为的理论模型适用于社交网络使用障碍，并指出与注意力相关方面有关的社交网络的特殊性。
