Illusions of perception in psychology

Perception of the properties and relationships of objects in space very often leads to the appearance of visual illusions.

Visual illusions - are called incorrect or distorted perceptions of size, shape, color or remoteness of objects.

Illusions and their psychology

Illusions have a different nature with hallucinations , since the latter arise from nothing in the absence of objects of external reality that could affect the senses. Hallucinations have a central origin and are associated with a disorder of brain activity. Illusions arise in the perception of existing objects in reality, which affect the receptors .

Visual illusions - psychology

Visual illusions can have a different character, depending on which they are classified:

1. False perception of the magnitude of the object.
2. Distortion of the shape of objects.
3. Illusions of geometric perspective.
4. Revaluation of vertical lines.

Optical illusions - psychology

Optical illusions - the deception of vision, errors in the evaluation and comparison among themselves of the proportions of various objects, distances, etc.

Psychologists know that not always the indications of the organs of perception are unambiguous and truthful. They depend on many environmental factors, as well as on the mood, physical and mental state of a person. In this regard, a large number of scientific studies are conducted, especially with regard to optical illusions, the action of which was experienced by any person, the so-called parallax.

Parallax - the displacement of subjects located at a different distance from the eye of the observer. This displacement can be caused by the movement of his eyes. So, for example, moving in a car to a person it seems that the objects that are along the road "run" faster than those that are at a greater distance.

Such examples can be cited by a whole multitude they are everywhere present in our lives and often interfere. Special it is important to take into account the influence of such factors in conducting various experiments and studies on visual modality, since they significantly affect the results.

Psychology of illusions

Experts argue that the emergence of visual illusions is due to established stereotypes, even if the phenomenon seen in reality is contrary to the already familiar.

Conclusion Psychologists and scientists do the same - the causes of the emergence of psychological illusions are most often associated not so much with psychophysiological phenomena as with a physical misperception of the brain.
