Since the coronavirus disease 2019 outbreak, the frequency of smartphone use has surged, which has caused an increase in smartphone addiction among individuals. Smartphone addiction can impair various cognitive abilities. However, to date, the impact of smartphone addiction on creative cognition remains unclear. The current functional near-infrared spectroscopy study compared neural differences between smartphone addiction tendency (SAT) and healthy control (HC) individuals during creative idea generation. In particular, by manipulating a key component of creative cognition, that is, overcoming semantic constraints, we explored whether SAT individuals could overcome semantic constraints. Both the SAT and HC groups completed the alternate uses task (AUT) in semantic constraint and unconstraint conditions. The results indicated that the prefrontal cortex (PFC) and temporal regions were less active during AUT in the SAT group than in the HC group. In the SAT group, the PFC was less active under constraint than unconstraint conditions. Moreover, both task-related and resting-state functional connectivity analyses indicated weaker coupling between the PFC and temporal regions in the SAT than in the HC group. Furthermore, the left dorsolateral PFC mediated the effect of smartphone addiction on creative performance. These findings provide unprecedented neuroimaging evidence on the negative impact of smartphone addiction on creative cognition.
自 2019 年冠状病毒病爆发以来，智能手机的使用频率飙升，这导致个体中出现了智能手机成瘾的现象。智能手机成瘾会损害各种认知能力。然而，迄今为止，智能手机成瘾对创造性认知的影响尚不清楚。目前的功能近红外光谱研究比较了智能手机成瘾倾向（SAT）个体和健康对照组（HC）在创造性思维产生过程中的神经差异。特别是，通过操纵创造性认知的一个关键组成部分，即克服语义约束，我们探讨了 SAT 个体是否能够克服语义约束。SAT 和 HC 组都在语义约束和无约束条件下完成了替代用途任务（AUT）。结果表明，与 HC 组相比，SAT 组在 AUT 期间前额叶皮层（PFC）和颞区的活动较少。在 SAT 组中，PFC 在约束条件下的活动低于无约束条件。此外，任务相关和静息状态功能连接分析表明，SAT 组中 PFC 和颞区之间的耦合比 HC 组弱。此外，左侧背外侧前额叶介导了智能手机成瘾对创造性表现的影响。这些发现提供了前所未有的神经影像学证据，证明了智能手机成瘾对创造性认知的负面影响。
