    Train your cognitive ability – PERCEPTION III

    The last post was all about perception and if I remember correctly I am in debt with some responses to the exercises I included in the last post.

    So let us start first with solving the exercises:

    Exercise 1: The picture left shows three geometrical figures. The picture right shows the same figures one after the other. 

    Exercise 2: The cylinder seems at its bottom part to become thinner.

    Exercise 3: The lines symbolize the optical distance. Things seem to meet when we look at them from a certain distance. 

    In this article, I want to show you how elementary cues from our environment are organized through certain laws also called Gestalt Laws. 

    Principle 1: Principle of Closeness 

    Similar elements are perceived as a group if they are close together.


    Principle 2: Principle of Similarity

    Similar elements are perceived as a line if they are close together. 


    Principle 3: Principle of Continuity

    We can guess how the lines will be continued even if we do not see it in the image.


    Principle 4: Principle of Unity

    Our eyes are used to see a full circle even if in the picture you see a little gap.


    Principle 5: Figure and Background

    The elements of the picture which have a sharp contour you perceive as a figure the rest is seen as the background.

    Consequently, I want you to show some other interesting facts:

    Perception of Background and Figure 

    We see the shape independently of the border, but we can also see the border independently of the shape.


    Perception of Faces

    When we try to decipher faces we mainly take account of two criteria: the distance between the eyes and the distance between the nose and mouth. 


    Next, we move to the fun part where I invite you to play some interactive games for training your perception!
