因時代的改變及科技的進步，網路成癮是近幾年被大量強調且討論的議題。網路成癮會對人們造成不僅是生理傷害、還有心理的影響。但有研究指出網路帶來的並非全然壞處，網路使用本身即是一項複雜的行為，長期使用網路也可能因認知訓練而造成認知能力的提升。本研究首先欲瞭解網路成癮傾向與認知能力(多重作業能力及工作記憶)之相關，並從目前已知的靜息態大腦網路進行初探，希望能發現網路成癮與多重作業能力在靜息態腦造影的表徵。
本研究計算出每位受試者14個已知大腦網路的內部功能性連結強度，並將認知能力與各連結強度作相關，求出各大腦網路內有關連性之連結。結果顯示網路成癮傾向與多重作業能力並無相關，但與工作記憶有顯著正相關，代表網路成癮可能只能提升特定認知能力，而非全面性認知能力的提升。另多重作業能力與工作記憶有顯著之正相關，顯示可能的確涵蓋工作記憶之範疇。靜息態方面，網路成癮之靜息態研究也發現到，成癮傾向愈高，多個大腦網路連結有愈衰弱之情形。多重作業能力則與多個認知功能網路有顯著的正相關，此結果反映了多重作業在現實中為一涵蓋多項認知功能的能力。
As the times evolve and advances in technology, the internet addiction has been a topic that has been heavily emphasized and discussed in recent years. The internet addiction can cause not only physical damage but also psychological effects. However, some studies have pointed out that the Internet using does not bring just disadvantages. The use of the internet itself is a complicated behavior and long-term use of the Internet may also lead to cognitive improvement due to cognitive training.
The research purposes was to understand the relationship between the internet addiction and cognitive abilities, and discovered the patterns in resting state.
First, we have correlations between the internet addiction, multitasking ability and working memory. Then, we calculated every subjects’ links strength in 14 networks and found correlations between the links and cognitive abilities (internet addiction and multitasking ability). As the result, there was no correlation between the internet addiction and multitasking ability, but a significant correlation between internet addiction and working memory. It meant that the internet addiction may only enhance specific cognitive abilities rather than comprehensive promotion. There was a significant positive correlation between multitasking ability and working memory. In resting state, the study also found that the higher the tendency of the internet addiction, the more debilitating the connections in many brain networks. Multitasking ability was significantly positively correlated with many functional networks, reflecting the ability which include a lot of cognitive functions in reality.
