Question 3

Cason is initially blinded as he walks out of a daytime movie.However,very rapidly his eyes begin to adjust to the bright light.What is the best explanation for his rapid recovery?&#10;A)Perceptual adjustments&#10;B)Sensory deprivation&#10;C)Oversensitivity of his rods and cones&#10;D)Sensory adaptation

Accepted Answer

Sensory adaptation is the process by which our sensory receptors adjust to changes in the environment. In this case, Cason's eyes rapidly adjust to the bright light, which can be explained by sensory adaptation.

Question 4

A common symptom associated with depression is loss of appetite.Research indicates that this occurs because&#10;A)our taste sensitivity is heightened by the neurotransmitters targeted by antidepressant drugs.&#10;B)our taste thresholds are increased by the neurotransmitters targeted by antidepressant drugs.&#10;C)our taste thresholds are unchanged by the neurotransmitters targeted by antidepressant drugs.&#10;D)we are more likely to label food as &#34;disgusting&#34; when we are emotionally aroused.

Accepted Answer

The answer of A common symptom associated with depression is...

Question 5

Attending to many modalities simultaneously is a phenomenon called&#10;A)bottom-up processing.&#10;B)top-down processing.&#10;C)parallel processing.&#10;D)selective attention.

Accepted Answer

Parallel processing refers to the ability of the brain to process multiple streams of information simultaneously. This allows us to attend to many modalities (e.g. visual and auditory) at the same time. Bottom-up processing refers to perception that is driven by the features of the stimulus, while top-down processing refers to perception that is driven by prior knowledge and expectations. Selective attention refers to the ability to focus on one particular stimuli while ignoring others.

Question 6

Pete has played lead guitar in a rock band for years.He often would turn the volume on his guitar way up and spend a great deal of time in front of the speakers during the shows.His resulting hearing loss over the past few years is most likely the result of

A)conductive deafness.
B)nerve deafness.
C)noise-induced hearing loss.
D)tinnitus.

Accepted Answer

Pete's exposure to loud music and sound over a prolonged period is most likely the cause of his hearing loss. This is known as noise-induced hearing loss, which occurs when the auditory hair cells in the inner ear are damaged by exposure to noise. Conductive deafness refers to hearing loss due to problems with the outer or middle ear, while nerve deafness is due to damage to the auditory nerve. Tinnitus is a ringing or buzzing sound in the ear and can be a symptom of hearing loss, but it is not the cause of hearing loss itself.

Question 7

The somatosensory system responds to sensory information about&#10;A)body position and equilibrium.&#10;B)temperature,touch and pain.&#10;C)taste and smell.&#10;D)sound and vision.

Accepted Answer

The somatosensory system is responsible for detecting sensory information about touch, temperature, and pain. Therefore, choice B is the best answer.

Question 8

The difference between high-definition television and regular television is analogous to which component of sound?&#10;A)Pitch&#10;B)Loudness&#10;C)Amplitude&#10;D)Timbre

Accepted Answer

High-definition television primarily differs from regular television in the clarity and detail of the image, which is analogous to timbre in sound. Timbre refers to the quality or color of a sound that makes it distinct from another sound at the same pitch and loudness, similar to how high-definition enhances the detail and quality of a visual image.

Question 9

According to _____,color vision evolved because perceiving color helped our early ancestors forage for food.&#10;A)binocular theory&#10;B)trichromatic theory&#10;C)opponent process theory&#10;D)gestalt theory

Accepted Answer

The trichromatic theory of color vision suggests that there are three types of color receptors, or cones, in the human eye that are each most sensitive to different wavelengths of light. This theory proposes that color vision evolved because being able to perceive different colors helped our early ancestors distinguish between different kinds of ripe fruits and other food sources, which would have aided in survival and reproduction.

Question 10

When light enters the eye,it first passes through what structure?&#10;A)Cornea&#10;B)Lens&#10;C)Pupil&#10;D)Sclera

Accepted Answer

The cornea is the outermost structure of the eye and is responsible for refracting and focusing light onto the lens. When light enters the eye, it passes through the cornea first before moving on to the other structures of the eye.
