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.The absolute threshold is an important tool for researchers studying the capabilities and limitations of human sensation and perception. It is defined as the lowest stimulus level that an organism can detect at least half the time. These limits can vary depending on factors such as motivation, expectation, and attention.The "absolute threshold of sensation" refers to the minimum intensity of a stimulus that a person can detect half the time.
