Properties of sensations

Feeling – this is the simplest mental cognitive process. All of them can be divided into three types: interoceptive, proprioceptive and exteroceptive. The first group includes those sensations that appear from the impulses that reach us from the internal environment of the human body; to the second – a reflection information about the location of the body in space, providing for the regulation and correction of the movement; the third group – the feelings that appear with signals from the outside world, create the basis for conscious action and behavior. Different types characterize certain properties of sensations, which we'll describe below.

Group interoceptive sensations to the brain bring information about internal processes occurring in the human body. This species is the most ancient and considered one of the less realized than others.

Proprioceptive sensations – reflected information about the location of the human body in space. They play a major role in the regulation of movement. Receptors of peripheral proprioceptive sensitivity are the joints, muscles, tendons and ligaments. The excitation arising in the receptors these are sensations that occur when the tension and relaxation of the muscles and changes in position of the joints. This group includes a special kind of sensitivity, which is called “the feeling of balance”. Their receptors are located in the inner ear and connected with the vestibular apparatus.

The Third most common group are feeling exteroceptive, which convey to the human body a variety of information emanating from the outside world. There are distance and contact experience. Contact can cause effects that are directly applied to the surface of a body or sensing body. Examples of the contact of senses-touch, taste. Distant are caused by a stimulus acting on the receptors of the analyzers in the distance. These include smell, hearing and sight.

Senses

The Most famous since the time of Aristotle types such as auditory, visual, olfactory, tactile and gustatory. But there are specific kinds of sensations, which give information about the acceleration, vibration, time. Some types of energy people do not feel the General level of consciousness (e.g., radiation, ultraviolet and infrared radiation, ultrasound, infrasound, etc.). Different types can interact with each other.

Properties of sensations

The senses are differences in the sources that generate them, and other differences. They have not only specific features but also General properties of sensation: quality, intensity, duration.

Intensity – the characteristics determined by the strength of the stimulus and the receptor.

Quality – a feature that distinguishes it from other forms of feelings and changes within this sense.

Duration is the time characteristic and determines the duration of the stimulus and its intensity.

Under the action of the stimulus on the receptors of the sense organs sensation may occur immediately, but after some time. This period is called latent, which have different types of sensations is different.

These Are properties of sensations, which we have considered in this article.

So, we have found that a sense — it is a mental cognitive process, which consists in reflection of properties of objects and the internal States of the organism under the influence of stimuli on the receptors of the senses. The functions of the senses are to promptly convey to the Central nervous system information about the status of the internal and external environment.
