Question

Quizplus · Accepted Answer

An absolute threshold refers to the minimum intensity at which a stimulus can be detected 50% of the time. The light touch of an ant crawling across someone's foot is an example of detecting a minimal stimulus, fitting the definition of an absolute threshold. Choices A, C, and D involve noticing differences or changes in intensity, which relate more to the concept of difference threshold or just noticeable difference (JND), not absolute threshold.
