AP PSYCHOLOGY

Detailed explanation-1: -Weber’s law: the principle that, to be perceived as different, two stimuli must differ by a constant percentage (rather than a constant amount).

Detailed explanation-2: -An absolute threshold is the smallest level of stimulus that can be detected, usually defined as at least half the time. The term is often used in neuroscience and experimental research and can be applied to any stimulus that can be detected by the human senses including sound, touch, taste, sight, and smell.

Detailed explanation-3: -Difference Threshold-minimum difference in intensity between two stimuli that one can detect. Absolute Threshold-minimum intensity of a stimulus that one can detect 50% of the time.

Detailed explanation-4: -Weber’s Law, also sometimes known as the Weber-Fechner Law, suggests that the just noticeable difference is a constant proportion of the original stimulus.
