AP Psych Unit 3: Vision and Body Senses

In a perception research lab, you are asked to describe the shape of the top of a box as the box is slowly rotated. Which concept are the researchers most likely investigating.

• feature detectors in the retina

• feature detectors in the occipital lobe

• placement of rods and cones in the retina

• binocular depth cues

• shape constancy

The blind spot in our eyes results from

• the lack of receptors at the spot where the optic nerve connects to the retina.

• the shadow the pupil makes on the retina.

• competing processing between the visual cortices in the left and right hemisphere.

• floating debris in the space between the lens and the retina.

• retinal damage from the bright light.

What function does the retina serve?

• The retina contains the visual receptor cells that transform light into neural impulses.

• The retina focuses light coming in the eye through the lens.

• The retina determines how much light is let into the eye.

• The retina determines which parts of the brain incoming light will be sent to.

• The retina connects the two optic nerves and sends impulses to the left and right visual cortices.

Color blindness and color afterimages are best explained by what theory of color vision?

• trichromatic theory

• visible hue theory

• opponent-process theory

• dichromatic theory

• binocular disparity theory

What behavior would be difficult without our vestibular sense?

• integrating what we see and hear

• writing our name

• repeating a list of digits

• walking a straight line with our eyes closed

• reporting to a researcher the exact position and orientation of our limbs.

Which perceptual process explains why you can see varied aspects of your favorite singer's face and instantly recognize him or her?

• Selective attention

• Accomodation

• Psychokinesis

• Blindsight

• Parallel processing

What do we call the specialized neurons in the occipital lobe's visual cortex that respond to particular edges, lines, angles, and movements?

• Rods

• Cones

• Bipolar cells

• Feature detectors

• Ganglion cells

Which of the following structures helps you most in detecting the color of your friend's shirt?

• Rods

• Cones

• Fovea

• Lens

• Cornea

Your best friend decides to paint her room an extremely bright electric blue. Which of the following best describes the physical properties of the color's light waves?

• No wavelength; large amplitude

• Short wavelength; large amplitude

• Short wavelength; small amplitude

• No wavelength; small amplitude

• Long wavelength; large amplitude

If you scratch your eye, which structure are you most likely to damage?

• Pupil

• Iris

• Cornea

• Lens

• Fovea
