Web18 Jul 2024 · Sensory adaptation: the processes by which organisms become more sensitive to stimuli that are low in magnitude and less sensitive to stimuli that are constant or ongoing in magnitude Sensitization: the type of sensory adaptation in which we become more sensitive to stimuli that are low in magnitude. also called positive adaptation. Webing the sensory information an observer can obtain about a stimulus despite limited sensory resources [4, 5, 6]. More mechanistically, adaptation can be interpreted as the attempt of the sensory system to adjusts its (limited) dynamic range such that it is maximally infor-mative with respect to the statistics of the stimulus. bateau gdansk saint maloWebSensory adaptation, selective attention, and signal detection theory can help explain what is perceived and what is not.
