The purpose of the lens is to

• focus light on the retina

• to process light

• to allow light into the eye

• to enable night vision

• to detect specific shapes

Neurons that fire in response to specific edges, lines, angles, and movements are called what?

• rods

• cones

• ganglion cells

• feature detectors

• bipolar cells

Which of the following represents perceptual adaptation?

• we recognize the taste of McDonald's food each time we eat it

• in photos of people, the people almost always are perceived as figure and everything else is ground

• from the time they are very young, most people can recognize the smell of a dentist's office

• the cold water in a lake doesn't seem so cold after you have been swimming in it for a few minutes

The process by which rods and cones change electromagnetic energy into neural messages is called what?

• adaptation

• accommodation

• parallel processing

• transduction

• perceptual set

Which of the following is most likely to influence our memory of a painful event?

• the overall length of the event

• the intensity of the pain at the end of the event

• the reason for the pain

• the amount of rest you've had in the 24 hours preceding the event

• the specific part of the body that experiences the pain

Place theory relates to which element of the hearing process?

• your mom throws out the milk because she says that the taste is "off"

Which perception process are the cones involved in?

• processing intense colors

• processing information related to our sense of balance

• supporting a structural frame to hold the eardrum

• trasmitting sound waves to the cochlea

• holding hair cells that enable hearing

Which of the following might result from a disruption of your vestibular sense?

• inability to detect the position of your arm without looking at it

• loss of the ability to detect bitter taste

• dizziness and a loss of balance

• an inability to detect pain

• loss of color vision

When you see blinking lights next to each other, like in the new turn signals, and perceive the light as moving is due to which process?

• perceptual set

• stroboscopic movement

• relative motion

• illusory effect
