Abstract: The article seeks to better understand the negative effects associated with the intensive use of digital
communication technologies: addiction and "addiction" to the Internet, depressive symptoms and anxieties
associated with social networks and the practice of media multitasking, fear of missing out (FOMO), perception
of stressful ghost signals and nomophobia related to the smartphone. In a transdisciplinary perspective, the article
analyzes the psychological and psychosocial processes, major effects and determinants of phenomena involving
negative effects and intensive uses of digital communication. Finally, it opens up new perspectives and research
hypotheses
