Sensation and perception
In our world there is a huge amountstimuli. They, in turn, act on those human organs that are responsible for different feelings. In general, initially any stimulus has a definite effect on our nerve tissues. As a result, there is an excitement that will later be transmitted to the hemispheres of the human brain. All these processes lead to the fact that people begin to feel sounds, warmth and touch and much more. That is, we can say that the sensation is the simplest psychological type processes that arise as a result of the interaction of the stimulus and the sensory organ. In addition, the sensation is, first of all, the material on the basis of which the basis for the knowledge of the surrounding world is created by man.
It is difficult to distinguish between sensation and perception. If we talk about perception, then by these words is meant a process of psychological character, thanks to which every person can simply enough realize what is happening around him. This can be done only on the basis of the work of his senses, as in the first case.
Than the sensation differs from perception? It is worth saying that this difference is to some extent artificial or, as experts say, logical. Do not think that our perception primarily depends and is composed only of sensations. This is not true. In this case, it would be possible to try to decompose the so-called perception into two parts: self-perception and sensation. However, this is simply impossible to do, since all such processes are very complex. They reflect the whole psychology of a particular person precisely at the time of human development, the stage of this process.
A person is not able to "feel" or "feel"tone, color, pain. However, he almost always perceives, for example, a specific blue or green object, perceives, or even feels real pain. At the same time, it must be said that no single property of a particular thing affects people in isolation. It is for this reason that it is not about sensations, but about the perception of something that is said.
If we talk about the prerequisites of any perception,then this, as already mentioned above, impulses or, for example, irritants. They act in some way on our senses. In addition, these organs can perceive such impulses not only with direct contact with the object, but also at a distance. Therefore, it is common to divide irritants into remote or contact ones. Sensation and perception varies depending on the condition of a person. For example, under hypnosis, people feel less pain, they hardly perceive conversations, words, do not react to touching and the like. In this state, a person can be inspired. Then the activity of his senses changes radically. The hypnotist does not react at all with his mimicry to piercing his skin, injections, gestures on pain, and so on. Thus the person under hypnosis all it feels, however does not show these feelings in gestures, for example.
Sometimes people have a change in their perception. Specialists call this state an illusion. This often occurs in some stressful situations, when the body experiences severe stress. Probably everyone knows that during the funeral it is customary to close all the mirrors in the apartment of the deceased person with a dense canvas. However, few people suspect why this is actually done. The thing is that people can see in them not only the deceased, but also the devil, the devil and so on. This is a kind of illusion, which is caused most often by anxiety and self-suggestion. If, for example, to remove its display in the mirror on a videotape, then as a result, there will be no changes at all. That is why it is worth mentioning that the subject is not distorted at all when it is displayed. However, it is distorted directly in the human mind.
As already mentioned above, sensation and perception- this is not the same thing. However, it is impossible to distinguish these concepts. Everyone can learn more about what sensation and perception are. Psychology and psychology have been dealing with such issues for a long time.
