Magnitude estimation is a psychophysical method used to quantify subjective sensory experiences. It involves asking observers to assign numerical values to the intensity of a stimulus, such as loudness, brightness, or perceived effort. This differs from methods like discrimination, which ask whether two stimuli are different, or classification, which asks which category a stimulus belongs to. In magnitude estimation, observers are typically given a standard stimulus with an assigned magnitude and then presented with other stimuli. They are asked to assign numbers to these new stimuli in proportion to their perceived magnitude relative to the standard. For example, if a sound is perceived as twice as loud as a standard sound assigned a value of 10, the observer might assign it a value of 20.
The key principle behind magnitude estimation is that sensory perception often follows a power law relationship
