Psychology Module 5 Chapter 5

As you are talking to a friend on your cell phone, you might find that you can't hear them because they are speaking very softly. If you ask them to "speak up," from a physical perspective you are asking them to ________ of the sound waves they are producing.

increase the amplitude

________ refers to the way that sensory information is interpreted and consciously experienced; ________ refers to what happens when sensory information is detected by a sensory receptor.

perception, sensation

Nikki was walking around a department store shopping one day, and did not realize that the shirt she was wearing looked just like the shirts worn by employees. When a stranger asked, "do you work here," she thought it was funny. The other customers' assumption that Nikki was a store employee demonstrates the Gestalt principle of _______.

similarity

Some neurons can only generate action potentials up to a certain speed, and no faster. This fact is a limitation of the ________ theory of pitch perception.

temporal

Ravon is deaf. He was born without the ability to hear, and has never experienced an auditory stimulus. When people write using "sound" type words like "loud," "soft," and "quiet," he sometimes has difficulty understanding what they are trying to convey. Ravon has ________ deafness.

congenital

When you watch the teacher at the front of the room, you are easily able to distinguish her from the white board (or chalk board) behind her. This demonstrates the Gestalt principle of _______.

figure-ground relationship

Vinnie is standing on one leg with his arms in the air. The ________ sense helps keep him balanced so he has less chance of falling over.

vestibular

Two lines appear to be a different length, though in reality they are the same length. This is known as the ________ illusion.

Müller-Lyer

Which nerve carries visual information from the retina to the brain?

Optic

Within the visible spectrum, our experience of red is associated with ________ waves of light.

longer wavelengths

If you watch a flock of birds flying overhead, each very close to the next one, you may perceive them as all being part of the same group. If they were all spaced very much apart, however, you may see them as individual birds not flying together. This distinction takes advantage of which Gestalt principle?

proximity

When a child works on a "connect the dots" puzzle, she can often see the completed work before she has finished all of the dots. Once there is enough visual information present, she's able to perceive the completed picture even though it is still incomplete. Which Gestalt principle does this demonstrate?

closure

Light waves are first transmitted through the ______ at the front of the eye and enter an opening called the ________ before shining into the retina.

Cornea; pupil

The amplitude of a wave is the height of a wave as measured from the highest point on the wave ______ to the lowest point on the _____.

Crest; trough

Ronaldo was born without the ability to experience pain, though he can perceive temperature differences and changes in pressure. What is his condition called?

congenital analgesia

Your ears receive sound waves and convert this energy into neural messages that travel to your brain and are processed as sounds. This is an example of ________.

transduction

________ disparity refers to the slightly different view of the world that each eye receives, and is a distance cue that allows us to perceive the depth of a given visual stimulus.

binocular

________ amplitudes are associated with ________ sounds.

higher; louder

One principle of civil engineering is that when you design a highway you should have traffic flow in the same direction and avoid interruptions to that flow as much as possible. Exit ramps tend to be curved so they cars don't have to stop rather than having 90-degree angles that force stops and starts. This is an application of which Gestalt principle?

Good continuation

What has research shown about processing subliminal messages?

In laboratory settings, people can process and respond to information outside of their awareness.

How does a cochlear implant enable the deaf to hear?

It receives incoming sound information and directly stimulates the auditory nerve to transmit information to the brain.

In a person whose eyes work in the usual fashion, the _______ will focus images perfectly on a small indentation in the back of the eye known as the ______.

Lens; fovea

What does the place theory of pitch perception suggest?

Receptors on different portions of the basilar membrane are sensitive to sounds of different frequencies.

What term describes the continuation of a visual sensation after removal of the stimulus?

afterimage

Sarit is at a bar full of music, chatter, and laughter. He gets involved in an interesting conversation with a woman named Mona, and he tunes out all the background noise. Sarit's friend, Karen, taps him on the shoulder and asks what song just played on the jukebox. Sarit says he doesn't know, even though he is sitting right next to the jukebox and is familiar with popular music. This illustrates the role that ________ plays in what is sensed versus what is perceived.

attention

The auditory cortex, in which sounds stimuli are processed for perception, is located in the _____ lobe.

temporal
