PSYC 100: Quiz 5

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

cornea; pupil

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

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

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

________ 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

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

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 wave ________.

crest; trough

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 that 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

________ amplitudes are associated with ________ sounds.

higher; louder

Participants were instructed to focus on either white or black objects, disregarding the other color. When a red cross passed across the screen, about one third of the subjects did not notice it. This research protocol demonstrates which concept?

inattentional blindness

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

longer wavelengths

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

optic

Catherine is at a crowded baseball game when she loses track of her son, Nick. Despite the loud cheering and noise of the crowd, she can pinpoint his location when he calls for her because she can distinguish the sound of his voice from the all the other voices. This illustrates ________ theory.

signal detection

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

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

temporal

Which of these is not one of the structures that comprises the outer ear?

the basilar membrane

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

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

What has research shown about processing subliminal messages?

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

________ 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

What does the place theory of pitch perception suggest?

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

Why are olfaction and gustation called chemical senses?

They have sensory receptors that respond to molecules in the food we eat or in the air we breathe.

Imagine yourself in a dark classroom reading PowerPoint slides. If an audience member were to check the internet using their cell phone and causing their screen to light up, chances are that many people would notice the change in illumination in the classroom. However, if the same thing happened in a brightly lit classroom during a discussion, very few people would notice. The cell phone brightness does not change, but its ability to be detected as a change in illumination varies dramatically between the two contexts. This is an example of ________

Weber's law

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

a figure-ground relationship

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

afterimage

Tyrahn's rods do not transform light into nerve impulses as easily and efficiently as they should, so he has trouble seeing in dim light. This is called ________ blindness

night blindness

Felicia smacks her thumb with a hammer while building a doghouse. The sense of ________ provides her brain with information about the pain she feels

nociception

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

Which type of processing involves the interpretation of sensations and is influenced by available knowledge and expectancies?

top-down

The hair cells in your cochlear convert sound wave energy into neural messages that travel to your brain to be processed as sounds. This conversion is an example of ________

transduction

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

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
