Infantile Behavior Patterns and Developmental Delays in Adolescents and Young Adults (Aged 12-29) with Screen Addiction

This study examines the relationship between screen addiction and infantile behavior patterns in individuals aged 12 to 29. Quantitative electroencephalography (qEEG) and physiological markers (HRV, SCL, T, Resp.) were utilized to assess the cognitive and neurophysiological effects of screen addiction. Findings reveal that screen addiction is linked to significant alterations in brain activity, including increased theta and/or alpha activity and reduced beta1 and/or increased beta2 and/or beta3 activity in the frontal and prefrontal cortex, leading to attention deficits, cognitive regression, and impaired executive functioning. Additionally, deficits in emotional regulation were observed, evidenced by low heart rate variability—an indicator of chronic stress and heightened susceptibility to anxiety and depression. On a social level, screen addiction was associated with increased dependence on external validation, reduced competitiveness, and difficulties in developing autonomy. The results support the hypothesis that infantile behavior patterns reinforced by excessive screen use contribute to regression in social adaptation and self-regulation. Based on these findings, targeted interventions are recommended, including screen time reduction, biofeedback neurotherapy, and structured programs aimed at fostering critical thinking and self-regulation to mitigate the adverse effects of screen addiction on cognitive, emotional, and social development.
