Question 1

The visual receptors are located in the back of the eye,or _______________.

Accepted Answer

The retina is the layer of cells at the back of the eye that contains the visual receptors, which are called rods and cones. The cornea, pupil, and iris are all located at the front of the eye and are involved in focusing light onto the retina.

Question 2

The part of the eye that gives it color is the:

Accepted Answer

The iris is the part of the eye that gives it color. The pupil is the black hole in the center of the iris that allows light to enter the eye. The cornea is the clear, outermost layer at the front of the eye that helps to focus incoming light. The retina is the layer at the back of the eye that contains cells that detect light and send signals to the brain. It does not give the eye its color.

Question 3

When you enter a dim room,the _______________ widens to let more light in.

Accepted Answer

The pupil is the black circular aperture in the center of the iris through which light passes into the eye. It widens or constricts to control the amount of light entering the eye based on the available light in the environment. When you enter a dim room, your pupil widens to let more light enter the eye, enabling you to see better in the low light conditions.

Question 4

The intensity of light is related to our perception of:

Accepted Answer

The intensity of light is directly related to our perception of brightness. Hue refers to the color of light, saturation refers to the purity or vividness of the color, and threshold refers to the minimum level of light required for us to perceive it.

Question 5

Neural tissue lining the back of the eyeball's interior is called the:

Accepted Answer

The retina is a layer of neural tissue lining the back of the eyeball's interior. The pupil is a hole in the center of the iris that allows light to enter the eye. The iris is the colored part of the eye that surrounds the pupil and regulates the amount of light entering the eye. The cornea is the clear outer layer covering the front of the eye.

Question 6

Hue is related to the _______________ of light.

Accepted Answer

Hue refers to the specific color or shade of light, which is determined by its wavelength.

Question 7

When the wavelength of a light is examined,one looks at:

Accepted Answer

When examining the wavelength of light, one measures the distance between the crests or troughs of the wave. This distance determines the color or type of light. Amplitude refers to the height of the wave, and saturation refers to the intensity of color, neither of which relates to wavelength measurement.

Question 8

Which of the following statements is true about white light?

Accepted Answer

White light is considered completely unsaturated because it contains all wavelengths of the visible spectrum at equal intensity, meaning it does not favor any particular hue.

Question 9

The ability to focus on some parts of the environment and block out others is referred to as:

Accepted Answer

Selective attention refers to the ability to focus on certain stimuli in the environment while ignoring others. Sensory deprivation is the extreme lack of stimuli, while sensory overload is an overwhelming amount of stimuli. Inattentional blindness refers to the phenomenon where we fail to notice unexpected stimuli in our environment because our attention is focused elsewhere.

Question 10

The wavelength of light is related to our perception of:

Accepted Answer

The wavelength of light is directly related to our perception of hue or color.

Question 11

The _______________ protects the eye and bends incoming light rays toward a lens located behind it.

Accepted Answer

The cornea is the clear outer layer of the eye that protects it from damage and works with the lens to focus incoming light. The pupil is the opening in the center of the iris that regulates the amount of light entering the eye, and the retina is the innermost layer of the eye that contains photoreceptor cells responsible for transmitting visual information to the brain.

Question 12

The complexity of light is related to our perception of:

Accepted Answer

The answer of The complexity of light is related to...

Question 13

During a break from his job as a waiter,Barnardo begins to read Hamlet and is so engrossed in the play that he fails to notice the clattering of dishes all around him.This is an example of:

Accepted Answer

Barnardo's focused attention on reading Hamlet and disregard for the clattering dishes around him suggests that he is selectively attending to the play and filtering out other stimuli. Therefore, the best choice is D, selective attention.

Question 14

Phoebe is feeling edgy and disoriented as she rests on her hospital bed in the infectious disease isolation unit.She wishes that the room had a television or at least a radio.It is likely that Phoebe is experiencing:

Accepted Answer

Phoebe's desire for external stimulation (e.g. television or radio) suggests she is experiencing sensory deprivation - a lack of sensory input from the environment.

Question 15

When Brett walks out of the theater into the glare of the sun,his _______________ gets smaller to let less light in.

Accepted Answer

The pupil is the part of the eye that contracts or dilates to control the amount of light that enters the eye. In bright light, the pupil gets smaller (contracts) to let less light in, and in dim light, the pupil gets larger (dilates) to let more light in.

Question 16

The capacity for _______________ protects us in daily life from being overwhelmed by all the sensory signals impinging on our receptors.

Accepted Answer

Selective attention allows us to focus on specific stimuli and filter out others, protecting us from being overwhelmed by all sensory signals. Sensory deprivation refers to a lack of stimulation, signal detection refers to the ability to detect specific signals in noise, and anatomical encoding refers to how sensory information is represented and processed in the brain. None of these directly relate to the capacity to protect us from being overwhelmed.

Question 17

The amount of light that gets into the eye is controlled by muscles in the:

Accepted Answer

The iris is the part of the eye that contains muscles which adjust the size of the pupil, thereby controlling the amount of light that enters the eye.

Question 18

Saturation is related to the _______________ of light.

Accepted Answer

The answer of Saturation is related to the _______________ of...

Question 19

Brightness is related to the _______________ of light.

Accepted Answer

Brightness refers to the subjective perception of how intense the light is. Intensity is a measure of the amount of light energy in a particular area, so D) intensity is the most appropriate choice.

Question 20

When Kayla's teacher switches on the lights after showing the class a video,Kayla's _______________ gets smaller to let less light in.

Accepted Answer

The pupils are responsible for controlling the amount of light that enters the eye. When the teacher switched on the lights, the pupils would have constricted to let in less light. Semicircular canals, cochlea, and papillae are not involved in controlling the amount of light that enters the eye.
