This study explored the influence of Social Media-induced instant gratification on cognitive functioning. Employing a Systematic Literature Review (SLR) grounded in the Search, Appraisal, Synthesis, and Analysis (SALSA) framework, the research synthesized insights from peer-reviewed empirical studies examining neurocognitive alterations associated with excessive Social Networking Site (SNS) usage. The findings revealed that habitual engagement with SNS platforms contributed to addictive behavior that is linked to diminished gray matter volume in brain regions essential to executive function. These neurostructural changes correlate with reduced creative problem-solving abilities and impaired decision-making faculties. The study concluded that Social Media-related Internet Addiction Disorder (IAD), as exacerbated by the dopamine-driven appeal of SNS, disrupted core cognitive mechanisms associated with creative problem-solving abilities and decision-making, thereby framing Social Media gratification not only as a behavioral concern but also as a cognitive risk.
