The Exocortex Deficit: A Quantitative Analysis of Cognitive Impairment and Physiological Stress Responses Following Artificial Connectivity Amputation

This study investigates the "Exocortex Deficit" hypothesis: the premise that smartphones have transitioned from external tools to integrated cognitive extensions. Utilizing a within-subjects quasi-experimental design (N=142), university students were subjected to a "Digital Amputation" protocol. Cognitive performance and state anxiety were measured in an Integrated State (device present) and an Amputated State (device removed). Quantitative analysis revealed a 28% decrease in logical reasoning accuracy and a 42% increase in state anxiety during device absence (p < .001$). These findings suggest that connectivity is now a base-level deficiency need, requiring a fundamental update to Maslow?s Hierarchy of Needs.
