Tærskelstigning
Tærskelstigning refers to a phenomenon where the perceived intensity of a stimulus needs to increase by a greater amount to be detected as a change, as the original intensity of the stimulus itself increases. This concept is often discussed in the context of psychophysics, the study of the relationship between physical stimuli and the sensations and perceptions they produce.
The underlying principle of tærskelstigning is closely related to Weber's law, also known as the Weber-Fechner
Tærskelstigning is not limited to a single sensory modality but applies across various senses, including vision,
