Buffer Theory
Buffer theory posits a dynamic mechanism in various disciplines, from chemistry to psychology, to describe systems' capacity to absorb change without significant disruption. Central to this concept is the notion of buffering agents that act as stabilizing forces, regulating fluctuations and maintaining equilibrium. Originally conceptualized in the context of acid-base chemistry, the application of buffer theory has expanded to encompass diverse phenomena, including ecological resilience, emotional regulation, and organizational resilience. Understanding the principles of buffer theory is essential for comprehending how systems adapt to stressors and maintain stability in the face of perturbations.
