|
|
|
the stimuli must differ by at least ten percent
|
|
|
the difference threshold decreases with the magnitude of the stimulus
|
|
|
the minimum difference needed for detection depends on the type of stimulus
|
|
|
Weber’s Law does not address this issue
|
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). Sensory adaptation: diminished sensitivity as a consequence of constant stimulation.
Detailed explanation-2: -The difference threshold is the smallest difference in stimulation that can be detected 50 percent of the time. The difference threshold is sometimes called the just noticeable difference (jnd), and it depends on the strength of the stimulus.
Detailed explanation-3: -Weber’s law, also called Weber-Fechner law, historically important psychological law quantifying the perception of change in a given stimulus. The law states that the change in a stimulus that will be just noticeable is a constant ratio of the original stimulus.
Detailed explanation-4: -The just noticeable difference (JND), also known as the difference threshold, is the minimum level of stimulation that a person can detect 50% of the time.
