It is commonly understood by sensitivity to that own and inherent capacity of any living being to perceive sensations on the one hand and on the other, to respond to small stimuli or excitations. This ability is possible to put into practice thanks to the senses that living beings have, touch, taste, hearing, smell, sight and that allow us to perceive the chemical or physical variations that occur both inside and outside..
There are three levels of sensitivity, extereoceptive or superficial, which is responsible for collecting external sensations, interoceptive, which deals with those at an internal level and proprioceptive, which informs us about the limbs and body movements, among others.
But also, the term sensitivity is used in other contexts and to signify matters that have nothing to do with the strictly physical. Then, sensitivity, in addition, is the natural tendency that human beings have to feel emotions or feelingsFor this reason, when a person tends to be very easily moved by certain circumstances that imply or have a strong emotional commitment, it is often said that that person displays a marked sensitivity.
Likewise, in contexts such as art, the term occupies a very special and determining place, since it is usually used to designate or give an account of the capacity that a person has and that allows him to approach, understand or have special training in matters related to art.
In the meantime and already going a little further from these issues that involve the feelings, facilities and perceptions that living beings in general and humans in particular have, sensitivity describes other issues.
In electronics for example, the sensitivity of an electronic device is the minimum signal magnitude required for the equipment to function.
And finally, for epidemiology, sensitivity is that capacity in which the complementary test that will allow detecting the disease in an individual is put into practice.
