Exam 3: Biology and Behavior

Cells called nociceptors respond to pain.

The phantom limb phenomenon is really just an urban legend.

A snack manufacturer finds that it must increase the salt content of its chips by 8% in order for a sample of consumers to notice that the chips are saltier than they were before. This example BEST illustrates the concept of a(n): 

The cones dark-adapt in about _____ minutes. The rods dark-adapt in about _____ minutes.

Retinal disparity is a monocular depth cue.

One can detect a single drop of perfume diffused in an area the size of a one-bedroom apartment. This is a(n):

Acme Foods wants to make its chips saltier, but it doesn't want to spend more than it has to on salt. A sample of consumers are asked to compare its current chip (saltiness = 100) with saltier versions and to say whether the new version is saltier. On average, sample consumers reliably say the new chip is saltier when its saltiness value is 108, but not when its saltiness value is below 108. Assuming Acme Foods' sample consumers are representative of people in general, which of the following BEST represents the difference threshold for saltiness?

According to frequency theory, the perception of:

The function of the basilar membrane is analogous to that of the lens in vision.

People become more sensitive to unchanging stimulation as it continues.

Which sentence expresses data-based processing?

The phenomenon of perceptual set demonstrates the importance of knowledge-based processes in perception.

There are significant cultural differences in the meanings associated with different colors.

Think of a favorite song and consider all the musical sounds it contains, from low-pitched sounds like those of an electric bass (30Hz to 40 Hz at the low end), through middle-frequency tones (say, middle C on a keyboard: 256 Hz), to higher-pitched sounds, such as those of a soprano voice (up to 1000 Hz) or the highest note on a piano keyboard (C8; about 4200 Hz). How do place theory, frequency theory, and the volley principle help explain how you perceive pitch in your favorite song?

Making an analogy between hearing and vision, the auditory hair cells in the ______ are similar to the ______ in the ______.

Shaya finds Chad attractive; her pupils are likely dilated.

With her right hand, Carly plays a middle C on her piano. With her left hand, she plays a note to her left on the keyboard. Her left hand plays a higher-frequency note than her right hand.

In vision, the amplitude of a light wave relates to people's perception of the brightness of a stimulus. To which perceptual dimension does the amplitude of a sound wave correspond in hearing?

Subliminal perception: fact or fiction?

Which method exemplifies a bottom-up means of closing the pain gate?
