the principle that, to be perceived as different, two stimuli must differ by a constant minimum percentage (rather than a constant amount).

Weber's law states that a just noticeable differenceMultiple Choicevaries according to people's perception.is a constant proportion of the intensity of an initial stimulus.is a variable proportion of the intensity of an initial stimulus.should always increase the intensity of an initial stimulus.

Which principle is demonstrated here? If you are in a room with 60 lights, you cannot tell when one goes out; but when you are in a room with 6 lights, you can easily tell when one goes out.Multiple choice question.sensory adaptationabsolute lawWeber's lawstimulus decay

Which of the following contradicts Weber’s law? A.A weightlifter who doesn’t notice a 5-pound difference in weight added in 1-pound increments, but who notices the difference in weight added in one 5-pound incrementB.A nonlinear relationship between the intensity of a stimulus and an individual’s ability to detect itC.The existence of a threshold, above which stimuli are detectable and below which stimuli are not detectableD.Hearing a whisper in a quiet room but not hearing a shout in a noisy room

Weber's LawMultiple Choiceis the study of the layer of the eye that light passes through.is based on the belief that a thin membrane vibrates when sound waves reach it.a law that describes the process of adapting to a new stimulus over time.is a basic law of psychophysics that states that a just-noticeable difference is in constant proportion to the intensity of the initial stimulus.
