Funny
illusions.
An illusion is a distortion
of a sensory perception, revealing how the brain normally
organizes and interprets sensory stimulation. While illusions
distort reality, they are generally shared by most people.
Illusions may occur with more of the human senses than
vision, but visual illusions, optical illusions, are the
most well known and understood. The emphasis on visual
illusions occurs because vision often dominates the other
senses. For example, individuals watching a ventriloquist
will perceive the voice is coming from the dummy since
they are able to see the dummy mouth the words. Some illusions
are based on general assumptions the brain makes during
perception. These assumptions are made using organizational
principles, like Gestalt, an individual's ability of depth
perception and motion perception, and perceptual constancy.
Other illusions occur because of biological sensory structures
within the human body or conditions outside of the body
within one·s physical environment... |
