Method of Constant Stimuli

The Method of Constant Stimuli is a way researchers measure how our senses perceive different levels of a stimulus, like brightness or sound. They present a series of stimulus intensities in random order, some just noticeable and others clearly perceptible. By asking participants whether they can detect each one, researchers determine the smallest or largest level at which the stimulus is perceived. This method helps create a detailed picture of sensory thresholds and sensitivity, ensuring that the results are not influenced by expectations or order effects. It’s a precise way to understand how we perceive varying intensities of stimuli.
