Sensory adaptation: it

Sensory adaptation: it
interpretations of sensory adaptation by scientists and experts, there are several.Among the most common - the definition as a natural sensitivity changes to existing analyzers under the special influence of the constant exposure to external stimuli.

Sensory adaptation is determined by adaptive changes in sensitivity to a certain intensity of one of the existing analyzers senses adapting stimulus.This is a consistent image that tries on a few options.

types

sensory adaptation Scientists consider sensory adaptation as the action of several directions.

  • Firstly, this adaptation in the category of sensations disappeared.This happens mostly when the loss of tactile sensitivity.For example, during the day a person wears clothes, and in the evening simply ceases to feel its heaviness, skin contact with the cloth trousers, underwear or t-shirts.
  • Secondly, the sensory adaptation is considered as a single sensitivity attenuation, which is formed by the action of a substantial stimulus.For example, the vis
    ual analyzer is manifested in a sharp decrease in the degree of sensitivity when people accidentally goes from unlit room in a room filled with dazzling light.
  • Third, there is a type of sensory adaptation, when there is increased sensitivity under any influence of a weak stimulus.This can result in an opposite example: in view of increasing voltage when one of the light enters the room darkened.

Interaction sensations

Various analyzers are responsible for a certain degree of adaptation.It should be noted that the high degree of sensory adaptation have visual, olfactory, tactile analyzers and describes the degree of reduced hearing and thermal analyzers.

virtually impossible to adapt the feeling of pain as possible adaptation to the painful feelings threatens the destruction of the human body.

process of formation of interaction sensations is realized on the basis of laws of change of the sensitivity of the analyzer while simultaneously irritated other senses.

There is a general law, the essence of which is that weak stimuli one analytical system to actively promote the growth of sensitivity in a different system, then the behavior of strong stimuli directly proportional.
