The intensity of light that Linda perceives 50 percent of the time is her absolute threshold, which is the minimum amount of stimulation necessary for her to perceive the light 50 percent of the time. Just noticeable difference refers to the smallest difference between two stimuli that she can detect, and Weber's constant is the ratio of the just noticeable difference to the original stimulus intensity. Subliminal limit refers to the point below which she cannot perceive the light at all.
