Question 1

What structure in your eye is most like the film in a camera?

Accepted Answer

The retina in the eye functions similarly to the film in a camera, capturing the images projected onto it by the lens.

Question 2

Rods and cones are found in the __________.

Accepted Answer

Rods and cones are photoreceptor cells that are located in the retina of the eye.

Question 3

The eyes convert light energy into neural responses that we experience as sight. The conversion of light energy into sight is done by receptor cells in the __________.

Accepted Answer

The retina contains photoreceptor cells that convert incoming light into neural signals that are transmitted to the brain via the optic nerve. The iris controls the size of the pupil, which allows light to enter the eye. The blind spot is the point on the retina where the optic nerve leaves the eye, and there are no photoreceptor cells in this area. Therefore, the correct answer is D, the retina.

Question 4

The physical stimuli for the sense of hearing are called __________ waves.

Accepted Answer

The physical stimuli for the sense of hearing are sound waves.

Question 5

The changes in pressure caused when molecules of air or fluid collide with one another then move apart again are called __________.

Accepted Answer

The changes in pressure caused by molecules colliding and moving apart again create sound waves. Hertz, decibels, and pitch are all related to sound, but they do not describe the specific changes in pressure caused by molecular collisions.

Question 6

The process by which rods and cones become more sensitive to light in response to lowered levels of illumination is called __________.

Accepted Answer

Dark adaptation is the process by which rods and cones become more sensitive to light in response to lowered levels of illumination. This is why it takes some time for our eyes to adjust to a darkened room after coming from a well-lit area. Option A is incorrect because afterimage resolution is the ability to see a clear image after a visual stimulus has been removed. Option B is incorrect because light adaptation refers to the process by which our eyes adjust to brighter environments. Option D is incorrect because afterimage adaptation is not a commonly used term in psychology.

Question 7

Which type of receptor cell is associated with seeing colors?

Accepted Answer

Cones are the type of receptor cells in the retina that are associated with seeing colors.

Question 8

Light receptors that see best at night are the __________.

Accepted Answer

Rods are photoreceptor cells in the retina that are responsible for low-light vision, such as in dimly lit environments or at night. They are more sensitive to light than cones and are densely located in the peripheral areas of the retina. Foveas and cones are responsible for high-acuity daytime vision and color vision, respectively. Shafts is not a correct term for any part of the eye.

Question 9

The ability to discern fine details in visual patterns is termed __________.

Accepted Answer

Visual acuity is the ability to see fine details in visual patterns. Temporal acuity refers to the ability to perceive changes in time, while visual perspicacity and myopia are not related to the ability to discern fine details in visual patterns.

Question 10

__________ are receptors that are best for seeing details.

Accepted Answer

Cones are the receptors in the retina that are responsible for color vision and the detection of fine details. They are most densely packed in the fovea, which is the area of the retina responsible for central vision and high visual acuity. Rods, on the other hand, are more numerous in the periphery of the retina and are better suited for low-light vision and detecting motion.

Question 11

Red, green, and blue are __________ colors.

Accepted Answer

Red, green, and blue are primary colors because they cannot be made by mixing other colors together. These are the three colors that can be combined in various proportions to create all other colors in the visible spectrum.

Question 12

Emily enters a dark movie theater from the bright sunlight. Which of the following is occurring in her retinal system?

Accepted Answer

When moving from bright sunlight to a dark environment, the eyes adapt by shifting from cone vision, which is dominant in bright conditions, to rod vision, which is more sensitive in low light. This adaptation process is relatively slow, taking several minutes to complete.

Question 13

The place in the retina where the axons of all the ganglion cells come together to leave the eye is called the __________.

Accepted Answer

The blind spot, or optic disc, is the point in the retina where the axons of all the ganglion cells converge to form the optic nerve, leaving the eye. This area lacks photoreceptors, hence it does not detect light, creating a "blind spot."

Question 14

The eyes detect different colors by using the __________.

Accepted Answer

Cones are the photoreceptor cells in the human eye that are responsible for detecting color. They are located in the retina and are responsible for color vision and visual acuity under bright light conditions. Rods, on the other hand, are responsible for detecting low levels of light and are less sensitive to color. The cortex is the outer layer of the brain responsible for processing sensory input, but it is not directly involved in color vision. Shaft is not a term used in the context of vision.

Question 15

Rods and cones are connected to __________.

Accepted Answer

Rods and cones are directly connected to bipolar neurons in the retina, which then connect to ganglion cells, transmitting visual information to the brain via the optic nerve.

Question 16

If you stare for 30 seconds at a red object and then look at a blank sheet of white paper, you will see a greenish image of the object. This phenomenon best supports the __________ theory of color vision.

Accepted Answer

The phenomenon described is best explained by the Hering opponent-process theory of color vision, which posits that the human visual system interprets color in terms of opposing pairs: blue-yellow, red-green, and black-white. After staring at a red object, the red-green color channel becomes fatigued, leading to a stronger response from the green side when looking at a neutral (white) background, hence the greenish afterimage.

Question 17

The physical stimuli for the sense of hearing are called __________ waves.

Accepted Answer

The physical stimuli for the sense of hearing are sound waves.

Question 18

Jake acted out in class and made poor grades. After a vision screening at the school, Jake's teacher moved him to the front of the class. Jake's academic and social behaviors improved. Jake probably has which vision problem?

Accepted Answer

Jake's behavior and poor grades improved after being moved to the front of the class, indicating that he had difficulty seeing objects from a distance. This is indicative of nearsightedness, which causes difficulty seeing distant objects clearly.

Question 19

When people are nearsighted, this most likely means that their eye __________.

Accepted Answer

Nearsightedness, or myopia, occurs when light entering the eye is focused in front of the retina, causing distant objects to appear blurry. This is typically due to either an elongated eyeball or a misshapen cornea, which affects the eye's ability to refract light properly.

Question 20

A dichromat __________.

Accepted Answer

Dichromats are individuals with a form of color blindness where they only have two types of functional cone cells in their eyes, instead of the normal three. This means they are unable to distinguish certain colors, typically either red-green or yellow-blue. Therefore, option B is the correct choice.
