Product Description

Video and lesson investigations on the topic of illusion. Key concepts include:

  • Vision can be fooled sometimes. The brain can only interpret one picture at a time.
  • It cannot see the two alternatives simultaneously.
  • Illusions work because of human perception ‘fills in’ the ‘gaps’ in what it sees. It makes the ‘best order’ it can of visual stimuli to make sense of it.
  • Illusions have competing stimuli.
  • One of the most common visual perception ‘illusions’ is based on the fact that our brain has to decide which is foreground (or figure) and which is background. With ‘double image’ pictures and figure and background are inter-changeable and can be reversed so that either way a meaningful picture can be seen.
    But the two different images cannot be seen at exactly the same moment by the brain.
