VISUAL GNOSIS
AND VISUAL MEMORY

 

cerveau-rapidite traitement fonctions cognitives

Visual gnosis refer to the ability to perceive an object through our vision, to represent it and to grasp its meaning.

 

What are visual gnosis?

Visual gnosis are simply a term that defines the ability to recognize objects through vision.

What you need to know is that there are 2 main visual cerebral pathways:

  • The “WHAT” pathway, specialized in the visual identification of objects. It extracts the visual information from the stimuli and processes it in order to recognize them and attribute a meaning to them.
  • The “WHERE” channel which allows us to localize objects in space.

When there is a brain lesion in one of these two pathways, it can cause problems that affect either the recognition of objects or the location of objects. When there is a disorder in one of the two pathways, it is called visual agnosia.

 

Visual gnosis disorders

When there is a disorder of visual gnosis, it is called visual agnosia. Visual agnosias are defined as the inability to recognize people or objects when presented visually. In order to conclude that there is visual agnosia, recognition in other modalities must be preserved. For example, in the tactile modality, i.e. by touching the object, or in the auditory modality, by hearing the noise it makes.

There are two types of visual agnosia:

  • Associative visual agnosia, which is the inability to recognize what one perceives correctly; the perception is correct but devoid of meaning. For example, one can copy a drawing, but one does not recognize what one is copying.
  • Perceptual visual agnosia, which is the inability to recognize because of perceptual deficits, what one sees is meaningless. For example, one is unable to copy a drawing.

 

Exercises to train and improve your visual gnosis

To improve your visual gnosis, try to observe your surroundings. Look for all possible details in an object, a person or a place. Focus on shapes, sizes and colors.

You can also reflect on the distance between objects or their positions in space. Then try to remember what you saw, without having the model in front of you. Do you remember all the details?

You can also do the opposite exercise. Think of an object you have at home, try to create a mental image of that object. Then take the object in question and see if there are any differences from what you just imagined.

Visual gnosis are therefore very important to be able to move in the environment and interact with others or with objects. The visual gnosias are necessary for 3 functions:

 

1. Identification of objects and people

This function allows us to recognize an object by looking at it.

Recognizing an object allows us to prepare for action, to know how to use an object and to adapt to the environment. We can also recognize people and know their names, but also remember common experiences.

Puzzle Plus

In this game, you have to solve a puzzle by moving the available pieces.

The player must identify the elements in the pieces and organize them to form the final image.

2. Analysis of objects and the environment

To move and interact with the environment we must be able to analyze the objects around us. We can therefore imagine the size of an object, its weight and its functionality.

Moreover, we can analyze the movement of an object or a person to imagine its trajectory, for example.

Clint the pirate

In this game, you have to move the character to his goal without touching the obstacles.

The player has to imagine the path of the character and analyze the position of each element. There are several ways to reach the goal, but by analyzing all the objects, you can find the fastest way.

3. Eye movements organization

Visual gnosis is something that happens through sight, so eye movements are very important. Indeed, when we look around us, our gaze moves over the different elements to “soften” the information. When we look at something, our gaze must be organized to be sure not to forget anything, so we look from top to bottom or from left to right.

Eye movements are also important for reading since our eyes must jump from one word to another following the line.

Geography

In this game, the person has to find a country or a State (US) on the map.

The eye movements are very important because you have to look at the map with your eyes. To find the right place of a country, we put our eyes in the zone where it is going to be located and then we look at all the countries to find the right one.
