Illusions

1. Fiction Illusions

   • An illusion caused when a figure is percieved even though it is not present in the stimulus
   • Kaniza Triangle
     • The triangle is percieved even though it is not present in the stimulus. It is explained using Gregorys theory because if you used Gestalt you will end up with a six pointed star.

3. Distortion illusion

   •  Where our perception is decieved by some aspect of the stimulus . This can affect the shape or size of an object
   • Herring Illusion
     • This is distortion illusion because it distorts our image to believe the liness converge in the distance. This can be explained using the Gregorys theory of linear perspective
     • Gregory
   • Ponzo Illusion
     • This is a distortion illusion as the bottom bar looks smaller than the top but they are actually the same. This is explained using the Gregorys theory of linear perspective as this states that lines appear to converge in the distance just like the Ponzo illusion
