Quizplus · Accepted Answer

The absolute threshold is the level of sensory stimulation that must be present for a stimulus to be detected at least 50% of the time. This is the lowest level of stimulation that can be detected by a sensory system. The just noticeable threshold (B) is the smallest difference in stimulation that can be detected between two stimuli, and the perceptional limit (C) refers to the maximum level of stimulation that can be processed by a sensory system. The subliminal threshold (D) refers to stimuli that are below the level of conscious awareness and are not detected at all.
