The Stimulus-Response Pathway meme utilizes the classical psychological framework to humorously illustrate how specific external triggers elicit immediate and often irrational reactions. While the template is rooted in biological and behavioral science, internet culture has repurposed it to highlight modern-day 'Pavlovian' behaviors—such as reflexively checking a phone when hearing a notification sound or losing all self-control during a holiday sale. It often features a flow chart or a simple diagram of a nervous system, bridging the gap between scientific theory and the absurd reality of daily human habits.
