Accepted Answer

Large-print books require more pages due to the larger font size, which results in them taking up more storage space compared to standard print books.

Question 3

Which of the following statements about the conceptual abilities of children with visual impairment is true?

Accepted Answer

It is true that infants and toddlers with visual impairment may be less likely to explore their environment on their own, so it is important for adults to encourage and assist them in doing so. Option A is incorrect as infants with visual problems may have some delay in their conceptual abilities. Option C is not entirely true as sight is typically the primary modality through which children develop conceptualizations of objects. Option D is also not entirely accurate as children with visual impairment may require more explicit information and instruction to pick up information incidentally.

Question 4

When walking, Lisa, an eighteen-year-old with blindness, has learned to attend to the subtle changes in pitch of echoes from objects as she moves towards them. Which phenomenon is responsible for these changes?

Accepted Answer

The Doppler effect is responsible for the changes in pitch of echoes as Lisa moves towards objects. This is due to the compression of sound waves as they bounce back towards her, creating a higher frequency (and therefore higher-pitched) sound. This phenomenon is similar to the changes in pitch of a siren as an ambulance or police car approaches and then passes by.

Question 5

Use of compressed speech enables students with blindness to

Accepted Answer

Compressed speech allows recorded texts to be played at a faster rate, which enables students with blindness to listen to the content more efficiently.

Question 6

A condition characterized by a preference for looking at near objects, non-purposeful gazing, distinct color preferences, attraction to rapid movements, and abnormal visual reflexes is

Accepted Answer

The condition described matches the characteristics of cortical visual impairment (CVI). CVI is a neurological disorder that affects the visual cortex of the brain, resulting in atypical visual processing and responses. It can lead to a variety of visual impairments and behaviors, including those described in the question. Strabismus is a misalignment of the eyes that can cause double vision or low vision, but it does not typically cause the other behaviors mentioned. Retinitis pigmentosa is a genetic disorder that affects the retina and can cause vision loss, but it does not typically cause the behaviors described. Nystagmus is a condition that causes involuntary eye movements, which can result in vision problems, but it does not necessarily cause the other behaviors mentioned in the question.

Question 7

A hereditary disease that usually causes the field of vision to narrow and also affects night vision is

Accepted Answer

Retinitis pigmentosa is a hereditary disease that causes the gradual breakdown and loss of cells in the retina, leading to a narrowed field of vision and difficulty seeing in low light conditions such as at night.

Question 8

A condition that involves an underdevelopment of part of the eye and is often associated with brain abnormalities such that a child is at risk for speech and cognitive disabilities is

Accepted Answer

Optic nerve hypoplasia involves an underdevelopment of the optic nerve which can lead to visual impairment. It is often associated with brain abnormalities and can increase the risk for speech and cognitive disabilities.

Question 9

The basic unit of braille is a

Accepted Answer

The basic unit of braille is a cell of six raised dots arranged in two columns of three dots each. Each cell represents a letter, number, punctuation mark or a contracted word. Therefore, choice C is the best answer as it accurately describes the basic unit of braille. Choice A is incorrect as a single dot does not convey any information on its own. Choice B is incorrect as braille is not written in words but in cells of dots that represent individual letters or contracted words. Choice D is also incorrect as braille cells are arranged in columns and not in a circular array.

Question 10

In comparison to sighted children, children who are blind

Accepted Answer

Children who are blind are not impaired in language functioning; they can develop language skills similarly to sighted children, although they may rely more on auditory and tactile experiences.

Question 11

Social adjustment problems for children with visual impairment are most likely the result of

Accepted Answer

Social adjustment problems for children with visual impairment are often caused by society's reactions and attitudes towards individuals with disabilities. Due to stereotypes and misinformation about blindness, children with visual impairments may face discrimination or exclusion from their peers. It is important for society to promote inclusivity and understanding of individuals with disabilities in order to support their social and emotional development.

Question 12

Most professionals now agree that the intelligence of people with blindness

Accepted Answer

It is not appropriate to directly compare the intelligence of people with blindness to that of people with sight because intelligence is a complex and multifaceted trait that cannot be measured solely by visual abilities. People with blindness may have developed compensatory skills and strengths in other areas, while people with sight may have different strengths and weaknesses. Therefore, it is best to consider each individual's unique abilities and strengths rather than making generalizations based on blindness status.

Question 13

People with sight can facilitate communication with people who are blind by

Accepted Answer

Using "telephone skills" involves clear verbal communication, which is helpful for people who are blind as it compensates for the lack of visual cues.

Question 14

A skill used by people who are blind to aid them in acquiring mobility is

Accepted Answer

The answer of A skill used by people who are...

Question 15

As a result of improper muscle functioning, Zelda's eyes are misaligned. This description suggests which one of the following conditions?

Accepted Answer

Strabismus is a condition in which the eyes are misaligned due to improper muscle functioning. This can lead to the eyes appearing to be looking in different directions, causing double vision and other visual disturbances.

Question 16

The National Federation of the Blind had a braille bill passed to

Accepted Answer

The National Federation of the Blind had a braille bill passed to ensure that teachers of students with visual impairment are proficient in braille. This would help to ensure that students who rely on braille as their primary mode of reading and writing have access to quality instruction and support.

Question 17

The lower achievement scores of students who are blind or who have low vision is most likely due to

Accepted Answer

The lack of exposure to braille or low expectations is the most likely reason for lower achievement scores among students who are blind or have low vision. This is because if the students are not provided with accessible materials or if educators have low expectations for their abilities, it can hinder their academic progress. While their visual problem may contribute to some difficulties, it is usually not the main cause of lower achievement scores. Listening skills and the emphasis on using braille forms of achievement tests may also have some impact, but they are not as significant as the lack of exposure to braille or low expectations.

Question 18

Repetitive movements such as rocking, rubbing the eyes, and grimacing displayed by some people who are blind are known as

Accepted Answer

The answer of Repetitive movements such as rocking, rubbing the...

Question 19

Approximately what percentage of the population of people with blindness currently uses braille as a primary reading method?

Accepted Answer

According to the National Federation of the Blind, only around 10-12% of blind individuals in the US currently use braille as their primary reading method.

Question 20

Accepted Answer

Excessive oxygen given to infants at birth can cause retinopathy of prematurity (ROP).
