Absolute threshold is the critical level of a stimulus that is necessary for the occurrence of a barely noticeable sensation or perception. This parameter of stimulus intensity denotes the smallest impact that is capable of attracting the organism's attention. When the absolute threshold is exceeded, the organism responds with corresponding perception, most often becoming aware of the sensation.
It is important to note that the absolute threshold may differ for different types of stimuli and different sense organs. Different sensory systems of the organism have their own unique threshold values, which highlights their specificity and diversity. This property makes the absolute threshold an important object of study in psychology and in research on perception, because it makes it possible to better understand how the organism perceives and responds to the surrounding world.
