AP PSYCHOLOGY

Detailed explanation-1: -Weber’s law maintains that the just noticeable difference of a stimulus is a constant proportion of the original intensity of the stimulus. As an example, if you have a cup of coffee that has only a very little bit of sugar in it (say one teaspoon), adding another teaspoon of sugar will make a big difference in taste.

Detailed explanation-2: -The difference threshold, often referred to as just noticeable difference (JND), is the minimum amount of change required to be detected in a stimulus. The concept was first proposed by German psychologist Ernst Heinrich Weber (1795-1878).

Detailed explanation-3: -Weber’s law: the principle that, to be perceived as different, two stimuli must differ by a constant percentage (rather than a constant amount). Sensory adaptation: diminished sensitivity as a consequence of constant stimulation.

Detailed explanation-4: -"Weber’s Law states that the ratio of the increment threshold to the background intensity is a constant. So when you are in a noisy environment you must shout to be heard while a whisper works in a quiet room.

Detailed explanation-5: -Weber’s law is an essential concept because it helps understand how people perceive different stimuli. The law reveals that perception of stimuli is relative, not absolute. This means that people don’t perceive stimuli in terms of their absolute intensity but rather their intensity relative to other stimuli.
