Emerging scientific evidence indicates that frequent digital technology use has a significant impact-both negative and positive-on brain function and behavior. Potential harmful effects of extensive screen time and technology use include heightened attention-deficit symptoms, impaired emotional and social intelligence, technology addiction, social isolation, impaired brain development, and disrupted sleep. However, various apps, videogames, and other online tools may benefit brain health. Functional imaging scans show that internet-naive older adults who learn to search online show significant increases in brain neural activity during simulated internet searches. Certain computer programs and videogames may improve memory, multitasking skills, fluid intelligence, and other cognitive abilities. Some apps and digital tools offer mental health interventions providing self-management, monitoring, skills training, and other interventions that may improve mood and behavior. Additional research on the positive and negative brain health effects of technology is needed to elucidate mechanisms and underlying causal relationships. .
新兴科学证据表明，频繁使用数字技术对大脑功能和行为有重大影响——既有负面的，也有正面的。过度使用屏幕和技术可能带来的潜在有害影响包括注意力缺陷症状加剧、情绪和社交智力受损、技术成瘾、社交孤立、大脑发育受损以及睡眠紊乱。然而，各种应用程序、视频游戏和其他在线工具可能有益于大脑健康。功能成像扫描显示，学习在线搜索的互联网新手老年人在模拟在线搜索过程中大脑神经活动显著增加。某些计算机程序和视频游戏可以提高记忆力、多任务处理技能、流体智力和其他认知能力。一些应用程序和数字工具提供心理健康干预措施，提供自我管理、监测、技能培训和其他干预措施，可能改善情绪和行为。需要更多关于技术对大脑健康的积极和消极影响的研究，以阐明机制和潜在的因果关系。
