AP Psych (Vision)

If we did not have cones in our eyes, we would not see

• Colors

• Shapes

• Sizes

• Distant objects

What is the first part of the eye that light hits?

• Lens

• Pupil

• Cornea

• Iris

Which three primary colors are detected by your cones?

• Blue, red, and yellow

• Green, red, and blue

• Black, gray, and white

• Blue, green, and purple

What is "sensation"?

• Process of neuronal activity traveling from our fingers to our brain

• Process by which our brain organizes and interprets information

• Process by which our sensory receptors detect stimuli from our environment

As we look at a flower, the intensity of the color we see is related to the light wave's

• Placement on the spectrum

• Length

• Hue

• Amplitude

The eye's "blind spot" is related to

• Light rays focusing too far in front of the retina

• Light rays focusing too far behind the retina

• A cluster of cells around the fovea which contain cones but no rods

• An area without receptor cells where the optic nerve leaves the eye

The size of the pupil is controlled by the

• Lens

• Retina

• Iris

• Cornea

The theory that the retina contains three different color receptors (red, green, and blue) is called

• Young Helmholtz Trichromatic Theory

• Gate Control Theory

• Place Theory

• Opponent Process Theory

Experiencing a green afterimage of a red object is most easily explained by the

• Opponent-Process Theory

• Frequency Theory

• Young-Helmholtz Trichromatic Theory

• Place Theory

In vision, transduction occurs within the

• Optic Nerve

• Visual Cortex

• Retina

• Cornea
