Small animals see the world in slow motion

This helps to escape from hischnikov



Small creatures like birds or flies can sense the movement differently than larger animals. Their perception more like a slow-motion footage of shooting such a scene in the movie "The Matrix", when the hero is flying bullet that allows animals to avoid the large predators.

It is known that every kind of animal perceives the world in a special way. Dogs, for example, have seen a terrible sight and underestimated the horizon, therefore focuses mainly on the basis of sounds and smells. Furthermore, animals have different dynamic ranges dogs can hear frequencies up to 40 kHz, dolphins - 150 kHz, and bats - up to 212 kHz. This is largely due to the adaptation of animals to their roles predators or victims.

In the vision, too, there is a kind of dynamic range, pertaining to the speed with which the world is perceived. Small animals, birds and insects can be one second to perceive more information than larger animals or people.

To understand this, just observe how a small bird inspecting the neighborhood: as a rule, the bird sharply pulls his head because her eyes are working at a higher clock rate. For birds and large carnivores people move in slow motion, and probably it seem incredibly slow and cumbersome. And the eyes, for example, flies react to visual stimuli in four times faster than the human eye.

In the metabolism, body size and perception of temporal information are closely linked: the larger the animal, the slower time for him perception. According to scientists, the reason is an evolutionary compromise between other neural power and time perception. Perhaps people are also susceptible to this effect: the perception of time with age faster, and small children perceive more information per second than adults.
