forskelsstærskel
Forskelsstærskel, also known as the just noticeable difference (JND), is a concept in psychology and sensory perception that refers to the minimum difference in stimulus intensity required for an individual to detect a difference between two stimuli. It represents the smallest change in a sensory input that can be perceived by a human or animal observer.
The concept originated from Gustav Fechner's work in the 19th century, forming a fundamental part of psychophysics.
Measurement of forskelsstærskel typically involves controlled experiments where subjects compare stimuli and indicate when they notice
Understanding forskelsstærskel has practical applications in various fields, including product design, ergonomics, and sensory testing, where
Overall, forskelsstærskel is a key concept for understanding the sensitivity and limitations of sensory systems, providing
