Introduction to Basal Skin Resistance Basal Skin Resistance (BSR) is a foundational psychophysiological metric that measures the electrical resistance of human skin. As a key component of Electrodermal Activity (EDA), BSR provides an objective, real-time index of the body’s internal physiological state. At its physiological core, skin resistance is determined by the electrical properties of […]
Introduction to Skin Conductance Skin Conductance (SC), often utilized interchangeably with the historical term Galvanic Skin Response (GSR), constitutes a fundamental physiological measure employed across the domains of psychology, neuroscience, and psychophysiology to quantify changes in the electrical properties of the skin. At its core, SC measures the ease with which a small, imperceptible electric […]
Electrodermal Activity: Measurement, Mechanisms, and Applications The Core Definition of Electrodermal Activity (EDA) The electrodermal response (EDR), often referred to broadly as Electrodermal Activity (EDA), is a fundamental physiological measure utilized across various scientific disciplines, most prominently in psychology and neuroscience. At its most basic, EDA reflects transient and tonic changes in the electrical properties […]
