AP Psych Vision/Hearing Review

Problems with the vestibular system would likely cause a person to

• not recognize shapes or colors

• stumble or fall

• fail to identify sound locations

• not be bothered by touching hot objects

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

• colors

• shapes

• sizes

• distant objects

What is "Sensation?"

• Process of neuronal activity traveling from our fingers to our brain.
• Process by which our sensory receptors detect stimulus energy from our environment.

• Process by which our brain organizes and interprets information

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 contains cones, but no rods.
• an area without receptor cells where the optic nerve leaves the eye.

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

In vision, transduction occurs within the

• Optic nerve

• Visual cortex

• Retina

• Cornea

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

• the opponent-process theory.

• frequency theory.

• place theory.

• the Young-Helmholtz theory.

A short wavelength would most likely produce what color?

• Red

• Yellow

• Green

• Blue

What receptor allows humans to see better in low or dim light?

• Rods

• Cones

• Tympanic Membranes

• Pupils
