This figure -O- tends to be perceived as a single line partially covered by a circle. Which Gestalt principle explains the tendency to organize the visual world in this way? Explain why.

Define sensation and perception. Explain what sense receptors are.

After taking your best friend to the airport, you stay to watch the plane take off. As you watch it go, the image of the plane on your retinas becomes smaller and smaller. Why is it that you perceive the airplane as flying away from you instead of shrinking? Briefly explain how this works.

There are two levels of processing involved in colour vision. The first occurs in the retina and the second in the ganglion cells and in neurons in the brain. Identify and explain the theory associated with each level.

In sensory deprivation studies, researchers were interested in what would happen if our senses adapted to most incoming stimuli. Explain the findings of the early studies in sensory deprivation. What has been revealed by later research?

In the Müller-Lyer illusion, most people perceive the line with the outward-facing branches as longer than the line with inward-facing branches, despite the fact that they are really the same length. Which of the following is a likely reason why this occurs?

Mei-Ling participated in an experiment where she had to press one button if she detected a visual stimulus and another button if she did not detect it. Five percent of the time Mei-Ling indicated a stimulus was present when it was not. From this information you can conclude that:
