Psychophysics
Psychophysics is the study of the relationship between physical stimuli and the sensations and perceptions they produce. It examines how changes in a stimulus, such as brightness or loudness, affect our subjective experience. Researchers use precise methods to quantify this relationship, often identifying thresholds at which a stimulus becomes perceivable or the smallest difference that can be noticed. This field helps us understand how we perceive the world around us and informs areas such as psychology, neuroscience, and sensory science.

Psychophysics is the scientific study of how we perceive sensory stimuli and the relationship between physical stimuli and our psychological experiences. It explores how changes in the intensity of a stimulus—like light, sound, or taste—affect our sensory perception. For example, how dim can a light be before we no longer see it? Psychophysics helps us understand human perception and aids in designing better sensory experiences in various fields, including psychology, marketing, and ergonomics. Essentially, it connects the physical world with our personal sensory experiences.
