Stimulus filtering : ウィキペディア英語版 | Stimulus filtering Stimulus filtering occurs when an animal’s nervous system fails to respond to stimuli that would otherwise cause a reaction to occur.〔 The nervous system has developed the capability to perceive and distinguish between minute differences in stimuli, which allows the animal to only react to significant impetus.〔 This enables the animal to conserve energy as it is not responding to unimportant signals. ==Adaptive value== The proximate causes of stimulus filtering can be many things in and around an animal’s environment, but the ultimate cause of this response may be the evolutionary advantage offered by stimulus filtering. An animal that saves energy by not responding to unnecessary stimuli may have increased fitness, which means that it would be able to produce more offspring, whereas an animal that does not filter stimuli may have reduced fitness due to depleted energy stores.〔 An animal that practices stimulus filtering may also be more likely to respond appropriately to serious threats than an animal that is distracted by unimportant stimuli.
