An absolute threshold is the smallest amount of stimulation needed for a person to detect that stimulus 50% of the time. This can be applied to all our senses: The minimum intensity of light we can see. The lowest volume of a sound we can hear. The smallest concentration of particles we can smell.

Signal Detection Theory is a psychophysical model that explains how humans make decisions based on sensory information. It is based on the idea that individuals may pick up on meaningful information, known as “signals,” from noisy and ambiguous stimuli.B. Signal-detection theory: theory which suggests how individuals are able to detect a minimal stimulus (signal) among other background stimuli (noise). This may influence how individuals make a decision in a specific situation. C. Receptor sensitivity is subject to change. 1. Sensory adaptation: a decline in receptor activity when stimuliFor example, some cells are stimulated by green and inhibited by red; others are stimulated byred and inhibited by green “The retina’s red, green, and blue cones respond in varying degrees to different color stimuli, as the Young-Helmholtz trichromatic theory suggested.” “The cones’ responses are then processed by opponent-process ...In the field of cognitive neuroscience, researchers extensively utilize quantitative methods derived from the Weber-Fechner theory, particularly in areas related to perception and cognition.
