True or false: Perceptual set is a predisposition or readiness to perceive something in a particular way.

True

top-down processing

Using your past experiences to inform your Interpretation of the sensation

bottom-up processing.

You went to the Army-Navy football game to meet your friend Kurt, who attends the Naval Academy. Finding Kurt turns out to be somewhat of a problem because half of the people at the game are approximately six feet tall, with similar hair cuts, wearing naval academy uniforms (including hats, which are called covers at the Naval Academy). The difficulty you have in finding Kurt occurs because you cannot use top-down processing. bottom-up processing. ear-to-ear processing. head-to-toe processing

Which of the following is NOT an example of perceptual constancy? A car you are watching is not getting bigger; it is just getting closer to you.

Your blue sweater is the same shade of blue whether you are outside or in a dimly-lit room. Your eye is drawn to the way a tablespoon of olive oil moves and changes shape on the surface of a bowl of water.
