Transcript of Perception
PERCEPTION How we process mental images.
MONOCULAR DEPTH CUES Relative Clarity
Distant objects appear less clear than they are. Moisture exaggerates depth.
Linear Perspective Parallel lines seem to come
together in the distance.
"Whilst part of what we perceive comes
through our senses from the object before
us, another part always comes out of
our own mind." -- William James
PERCEPTUAL CONSTANCY Perceiving that the size, shape, and
lightness of an object as unchanging even as the image on the retina of the eye changes.
SIZE CONSTANCY When an object comes nearer, our brain
understands that it’s not getting bigger even if it appears to.
Which is bigger?

SHAPE CONSTANCY Even if the angle in which we are
looking things changes we don’t see the object in a different shape.
LIGHTNESS CONSTANCY When the light around the object
changes the objects apparent color changes but it’s actual color doesn’t.
PERCEPTUAL SET Mental predisposition to perceive
something one way and not the other.
