Psychophysics is a subfield of psychology that explores the relationship between physical stimuli and sensory perception. Researchers in psychophysics study how people perceive and interpret sensory information, such as light, sound, touch, taste, and smell. They seek to understand how individuals perceive and respond to stimuli, as well as the thresholds at which stimuli can be detected or distinguished. Psychophysics combines principles of physics and psychology to investigate the complex interactions between physical stimuli and psychological processes. This research area helps to deepen our understanding of human perception and behavior.
