Document Summary
In tv screens, nothing is moving, we just perceive it to be in reality we are just seeing a series of still photographs flashed very quickly. Phi phenomenon: when looking at flashing neon signs, there is no movement, but we perceive the alternating stationary lights as movement (because the brain constructs reality!) Perceptual constancy: ability to perceive objects as remaining unchanging and constant even if visual stimulus changes ex when olga is facing sideways she is still olga x) Size constancy: ability to perceive object as staying the same size despite changes in sensory input (ex. Object moving away from you is still the same size in real life as it was when it was near you) Shape constancy: ability to perceive shape (ex a cube) as staying the same despite rotations. Colour constancy: ability to perceive colour as staying the same despite changes in light conditions.
