Definition of the noun absolute threshold
What does absolute threshold mean as a name of something?
- the lowest level of stimulation that a person can detect
Absolute threshold: In neuroscience and psychophysics, an absolute threshold was originally defined as the lowest level of a stimulus —light, sound, touch, etc.—that an organism could detect. Under the influence of signal detection theory, absolute threshold has been redefined as the level at which a stimulus will be detected a specified percentage of the time. The absolute threshold can be influenced by several different factors, such as the subject's motivations and expectations, cognitive processes, and whether the subject is adapted to the stimulus.
