sensations - it's just a mental cognitive process.All of them can be divided into three types: interoceptive, proprioceptive and exteroceptive.The first group includes sensations appearing on the pulses that reach us from the internal environment of the human body;the second - a reflection of information on finding a body in space, provides for the regulation and correction of movement;the third group - the sensations that occur due to signals from the outside world, creating the basis for conscious actions and human behavior.Various sensations characterize certain properties, but we will describe below.
Group interoceptive sensations brings to the brain information about the internal processes occurring in the human body.This species is the most ancient and it belongs among the less conscious than others.
Proprioceptive sensations - is the reflected information about the location of the human body in space.They play a major role in regulating movement.The receptors are peripheral proprioceptive sensitivity in the joints, muscles, tendons and ligaments.Excitation arising in these receptors belong to the sensations that occur when tension and relaxation of muscles and changes in the position of the joints.This group includes a special kind of sensitivity, which is called the "sense of balance."These receptors are located in the inner ear and connected to the vestibular apparatus.
Third, most prevalence group are exteroceptive sensations that bring to the human body a variety of information coming from the external world.There are distant and contact sensations.Contacts can be caused by exposure, directly attached to the surface of the body or the body of the perceiver.Examples of contact sensations - touch, taste.Distant caused by stimuli acting on the receptors of the analyzers in the distance.These include the sense of smell, hearing and sight.
Types sensations
most known since the days of Aristotle types such as auditory, visual, olfactory, tactile and gustatory.But a person has and the specific types of experiences that provide information about acceleration, vibration time.Some types of energy a person does not feel at all at the level of consciousness (eg, radiation, ultraviolet and infrared radiation, ultrasound, infrasound and others).Different types can interact with each other.
Properties sensations
Types sensations are differences in the sources of their generators, and other differences.They have not only the specifics, but the general properties of sensations: the quality, intensity, duration.
intensity - a characteristic determined by the strength of the stimulus and the state of the receptor.
quality - a feature that distinguishes it from other forms of sensations and changes within this kind of feeling.
Duration is a time characteristic and determines the duration of the stimulus, and its intensity.
The action of the stimulus on the receptors of the senses sensation may not occur immediately, but after some time.This period is called latency, which have different kinds of experiences are different.
These properties feelings that we have reviewed in this article.
So, we found that feeling - it's a mental cognitive process, which is to reflect the properties of objects and internal states of the organism under the influence of stimuli on the receptors of the senses.Options consist of sensations to quickly and promptly bring to the human central nervous system on the status of internal and external environment.
