Perception How do we really “know” what’s out there? Perception is always indirect. Real world: Distal stimulus (tree). Some energy bounces off the tree and reaches our eyes (image of the tree on our retina is the proximal stimulus ). Lots of processing of that proximal image in our brains to get to the final percept : what we experience when we look at the tree.

How do we come to know the world? The nativist (a.k.a. rationalist) position--Much of our knowledge is based on innately given characteristics. From this perspective, sensation and perception should be “hard- wired.” The empiricist position--We are born as blank slates ( tabula rasa ). Thus, we must learn to sense and perceive.
