long as the stimulus or stimulus difference remains below threshold, its perception is, as one says, unconscious. What’s a personal experience you’ve had with this? In psychology, absolute threshold is the smallest amount of intensity from a stimulus that is detected by a person's senses. By the end of this section, you will be able to: Distinguish between sensation and perception. Ernst Weber, a well‐known early investigator, observed that regardless of their magnitude, two stimuli must differ by a constant proportion for their difference to be detectable. Sensation: Perception: The process of detecting a stimulus, such as • light waves (vision) , • sound waves (hearing) , • chemical molecules (smell and taste ), • heat or pressure (touch). The size of the difference threshold is greater for heavier objects than for lighter ones. What is difference threshold in psychology? This best illustrates Question 2 options: a) Weber's law.

The difference threshold is demonstrated at the moment a change in the nature of such stimuli is detected.
