Psychophysics is the branch of psychology that deals with the relationships between physical stimuli and their subjective (psychological) effects. The study titled "the effect of light intensity on the experience of brightness" directly investigates this relationship by examining how changes in a physical stimulus (light intensity) affect a psychological experience (perceived brightness).  Psychophysics is the study of the relationship between physical stimuli (such as light intensity) and the behavior or mental experiences (such as the experience of brightness) the stimuli evoke.
