Psych 101 Unit 4

When Atanas describes the "color" of a note played on the guitar, what's he referring to?

a large number of pitches all being produced at the same time.

The frequency which is not audible to the human ear is

50000 Hz.

One of the world's brightest flashlights is "The Torch" - in fact, the light energy it produces is so powerful that it can fry an egg, or start a fire, in just a few seconds. Which of the following aspects of The Torch's light is so powerful?

Amplitude.

The brain area involved in perceiving visual motion (MT) is a part of the ...

Dorsal Stream.

Some animals, like bees, are able to see ultraviolet light energy. What is true of ultraviolet light?

It has a shorter wavelength that violet light.

Imagine that it's possible to become adapted to the sight of cats. If I spend all day looking at cats, and then I suddenly see a mongoose, what will that mongoose look like?

It'll look very different from a cat, because I've reduced my sensitivity to the appearance of cats.

The smell of something burning reminds you that you forgot to set the timer on the stove. What has happened?

Perception of a burning smell.

_________ above 85 dB is enough to cause hearing damage.

Sound amplitude.

Sugar activates TAS1R2 receptors on your tongue, triggering action potentials, and sending nerve impulses to the brainstem. What has happened?

Transduction of the taste of sugar.

The Rubin vase illusion demonstrates:

figure ground separation.

A guitar string that has more tension and pressure, that vibrates more quickly, will produce a _______ sound than a string that has less tension.

higher-pitched.

An example of apparent motion is...

when flashing lights surrounding a marquee seem to move around the sign.

When you first dive into a cold swimming pool, the temperature is shocking. But thanks to sensory adaptation...

your sensitivity to the cold will decline.

Which of the following is responsible for the transduction of sound information into neural information?

Hair cells.

My son throws a ball at my face, and the ball's pressure against my skin stimulates pain receptors and touch receptors. What has happened?

Sensation of the ball hitting my face.

Vibrations from a guitar string cause changes in air pressure that arrive in a person's ear. What has happened?

Sensation of the guitar.

The frequency of a sound is _________.

The number of waves that pass in one second.

What does a cochlear implant do?

Transmits sound information to electrodes that directly stimulate the auditory nerve.

If someone has conductive hearing loss, the results of the Rinne test will be:

Worse hearing through the pinna than the mastoid.

Most movies are filmed at 24 frames per second. We perceive these static images as a moving image because of...

apparent motion.

A complex tone with multiple frequencies causes peak vibration of the basilar membrane...

at places along the cochlea associated with each of the frequencies.

The Rinne test is based on the fact that, in normal hearing, air (through the auditory canal) conducts sound ________ bone (through the mastoid).

better than.

Our sensory systems respond more strongly to ___________ than to constant stimulation.

changes in stimulation .

Radio waves have _________ than visible light.

larger wavelength.

Interaural time differences are used to perceive the location of ...

low frequency sounds.

The Ames illusion demonstrates:

monocular depth cues.

The Waterfall illusion demonstrates:

motion aftereffects.

The fact that different cells along the basilar membrane are stimulated by different frequencies of sound is most consistent with...

place code.

A harmonic played on the guitar _______ than a note played with the string pressed on the fret.

sounds more like a pure tone.

High frequency sounds that arrive at the ear closer to the sound source are louder than the sounds in the farther ear because...

the head partially blocks the sound energy.
