Sensation is a tool for a person's perception of himself and the world around him. All living beings have the ability to sense certain phenomena. However, only a person can be aware of this, determine the nature of his feelings and talk about them. What is the concept of "feeling"? What are the stages of its occurrence, and what types of them are distinguished in psychology? All this will be discussed further.
So, sensation is a normal mental process, which is an (unconscious or conscious) product of the activity of the central nervous system that occurs under the influence of stimuli (external and internal).
As a physical process, it can be explained by sensitivity organism to the sensory influences of the environment. With the help of various receptors, a person perceives information about his internal state, as well as about the outside world.
Besides, sensation is also a physiological process in which irritation of receptors gives rise to a nerve impulse. The latter, in turn, is transmitted to the necessary parts of the brain, where the reaction is received and analyzed.stimulus.
The system for classifying sensations in psychology consists of three groups:
proprioceptive, exteroceptive and interoceptive. Proprioceptive sensation reflects the movement of the body in space by receptors in the vestibular apparatus and muscles. The exteroceptive gives a description of the properties of the external world, thanks to the receptors on the body (taste, hearing, sight, smell, tactile and skin sensations). So, to know the taste, you need to eat something, and to get to know the object, you need to touch it. Interoceptive arises when receptors in internal tissues and organs are stimulated and speaks about their state.
Also, there are conscious and unconscious sensations. The former include significant conscious experiences, which sometimes even testify to the unusual capabilities of a person. These include the feeling of deja vu - a state in which one feels that a similar situation has already happened, but this has nothing to do with a specific moment from the past. This phenomenon is very common in humans, but it is impossible to cause it artificially, and it occurs extremely rarely. The reasons for its appearance have not been found, but it is suggested that this happens due to the work of the part of the brain that is responsible for perception and memory.
Usually deja vu causes a feeling of unreality of what is happening. Sometimes it seems that it could just be a dream, but it happens that such a phenomenon can be perceived as a prediction of the future or as a memory of a “past life”. In general, this phenomenon is difficultdescribe, and a typical reaction for a person will be to correlate it with some recent past.
Unconscious sensations include those that occur during sleep, with a decrease in the overall level of awareness, as well as in the form of intuitive feelings (intuitions).
Based on this, we can say that sensation is a many-sided specific concept. It describes phenomena that occur at different levels of perception and have different qualities, intensity (aggravation and dullness) and duration.
