    • Key Terms
      • Perception is how we interpret data we collect from our senses
      • Illusions is when we misinterpret data we collect through our senses
      • Shape Constancy is when an object keeps it's shape
      • Colour Constancy is when objects appear the same colour in different lighting conditions
      • Depth Cues: Linear Perspective- the sides converge at a point in the distance. Height in Plane- if something is above the imaginnary horizontal line it's further away. Sumper-imposition- If something blocks the imagine in front. Relative Distance- as we look into the distance objects get smaller. Texture Gradiant- something goes blurry or unfocused in the distance
    • Core Theory
      • Top Down Processing, when our perception is influenced by what we expect to see
      • Perceptual Set is the tendency to perceive based on what we expect
      • Motivation is how we feel effects how we see things
