Question 1

One explanation for extraordinary performances of people with savant syndrome is that the _____ of the brain is damaged, freeing them from the "distractions" of language, concepts, and higher-level thoughts.
A)left hemisphere
B)right hemisphere
C)corpus callosum
D)reticular formation

Accepted Answer

Studies suggest that some savants have a damaged or less active left hemisphere, which is responsible for language, logic, and higher-level thinking. This frees up the right hemisphere to excel in areas such as music, art, and spatial reasoning.

Question 2

People with IQs between 40 and 50 and adaptive behaviors within the same functioning range would be described as having which degree of intellectual disabilitiy?
A)moderate
B)profound
C)severe
D)mild

Accepted Answer

According to the standard definition of intellectual disability, individuals with IQs between 40 and 50 and adaptive behaviors within the same range would be classified as having moderate intellectual disability. This means they may have significant challenges with functional skills, but may still be able to learn some basic academic and vocational skills with appropriate support.

Question 3

Which of the following is a possible explanation for the remarkable mental abilities displayed by individuals with savant syndrome?
A)They suffer from a familial intellectual disability, which results in this pseudo-giftedness.
B)It is caused by a mutation on the X chromosome.
C)It is caused by a mutation on the 21st chromosome.
D)They have suffered damage to the left hemisphere, which freed them from the "distractions" of language, concepts, and higher-level thoughts.

Accepted Answer

Individuals with savant syndrome may have suffered damage to the left hemisphere of their brain, which allows their right hemisphere to function uninhibited. This can result in enhanced abilities in certain areas, such as music or art, but also may come with deficits in other areas, such as language and communication.

Question 4

People with IQs below 20 and adaptive behaviors within the same functioning range would be described as having which degree of intellectual disabilitiy?
A)moderate
B)trainable
C)severe
D)profound

Accepted Answer

People with IQs below 20 and adaptive behaviors within the same functioning range would be classified as having a profound level of intellectual disability. This means they have significant limitations in intellectual functioning and adaptive behaviors, which affect their ability to function independently in daily life.

Question 5

A person with limited intelligence, but who shows exceptional mental ability in one or more narrow areas, such as mental arithmetic, calendar calculations, art, or music is said to have
A)pseudo-giftedness.
B)savant syndrome.
C)Klinefelter's syndrome.
D)borderline intelligence.

Accepted Answer

The term "savant syndrome" is used to describe individuals with low general intelligence but with exceptional specific abilities, such as in music, art, or mathematics. This condition is rare and occurs more frequently in individuals on the autism spectrum. Options A, C, and D are not related to this specific phenomenon.

Question 6

Kim Peek was the model for Dustin Hoffman's character in the movie Rain Man.Although Kim had difficulty with abstract thinking and tests of general intelligence, he exhibited exceptional mental abilitiy in memorizing books, zip codes, and classical music.Kim Peek has what is known as
A)gifted autism.
B)savant syndrome.
C)Turner's syndrome.
D)a schizotypal personality.

Accepted Answer

Kim Peek exhibited exceptional mental abilities in memorizing books, zip codes, and classical music, which is characteristic of savant syndrome. Savant syndrome is a condition in which a person with cognitive or developmental disabilities has one or more areas of expertise, talent or brilliance that are in contrast with their overall limitations.

Question 7

Jonathan has an intellectual disability.He is unable to read books or to read music and has had no music lessons.However, he is able to play any song he hears once on the piano.Jonathan would best be described as having
A)a schizotypal personality.
B)savant syndrome.
C)Turner's syndrome.
D)pseudo-giftedness.

Accepted Answer

Jonathan's ability to play any song on the piano after hearing it once is a characteristic of savant syndrome. Individuals with savant syndrome often have exceptional abilities in a specific area, despite having intellectual disabilities in other areas. Jonathan's inability to read books or music also suggests a learning disability, which is often seen in individuals with savant syndrome. Therefore, B is the best choice.

Question 8

One explanation for extraordinary performances of people with savant syndrome is that it results from
A)chance mutations in their genetic make-up.
B)intense practice.
C)damage to their right brain hemisphere.

Question 9

An intellectual disability is formally defined by deficiencies in
A)aptitudes and kinesthetic skills.
B)intelligence and scholastic aptitudes.
C)language and spatial thinking.
D)IQ and adaptive behaviors.

Accepted Answer

Intellectual disability is defined by both an IQ score that is significantly below average (usually below 70) and deficits in adaptive behavior that affect everyday functioning. Aptitudes, scholastic aptitudes, language, and spatial thinking may be affected, but they are not the defining characteristics of intellectual disability.

Question 10

A person with an IQ score below 70 and a significant impairment in adaptive behaviors is said to have
A)an intellectual disability.
B)a learning disability.
C)dyslexia.
D)savant syndrome.

Accepted Answer

An IQ score below 70 and a significant impairment in adaptive behaviors are the criteria used to diagnose an intellectual disability. This is a condition that affects a person's intellectual functioning and can impact their ability to learn, communicate, and perform everyday tasks. A learning disability, dyslexia, and savant syndrome are all different conditions with distinct characteristics and diagnostic criteria.

Question 11

People with IQs between 55 and 70 and adaptive behaviors within the same functioning range would be described as having which degree of intellectual disability?
A)moderate
B)profound
C)severe
D)mild

Accepted Answer

Individuals with IQs between 55 and 70 are typically classified as having a mild intellectual disability.

Question 12

Savant syndrome refers to a person
A)having either a high IQ or special talents or aptitudes.
B)having a mild intellectual disability associated with homes that are intellectually, nutritionally, and emotionally impoverished.
C)having limited intelligence but showing exceptional abilities in art, music, mental arithmetic, or calendar calculations.
D)a genetic form of intellectual disability caused by the presence of an extra chromosome.

Accepted Answer

Savant syndrome is a rare condition in which a person with limited intelligence shows exceptional abilities in specific areas such as art, music, mathematics or memory. This person may have difficulty with basic life skills, but demonstrates exceptional performance in their special area of talent. Therefore, option C is the correct choice. Option A is incorrect because high IQ or special talents alone do not define Savant syndrome. Option B is incorrect because Savant syndrome is not associated with mild intellectual disability or an impoverished home environment. Option D is incorrect because Savant syndrome is not caused by an extra chromosome.

Question 13

Early signs of giftedness include
A)learning to walk by nine months.
B)a sense of selfishness and self-centeredness.
C)being absent-minded and disorganized.
D)seeking out older children and adults.

Accepted Answer

Seeking out older children and adults is an early sign of giftedness as it shows a desire for intellectual stimulation and social interaction with those who can offer more challenging conversation and activities. Learning to walk by nine months, being self-centered, and being absent-minded are not necessarily early signs of giftedness.

Question 14

People with IQs between 25 and 35 and adaptive behaviors within the same functioning range would be described as having which degree of intellectual disabilitiy?
A)severe
B)moderate
C)educable
D)trainable

Accepted Answer

People with IQs between 25 and 35 are typically classified as having a severe intellectual disability. This classification is based on the level of cognitive and adaptive functioning.

Question 15

Using IQ scores as the sole measure of giftedness
A)is the quickest way to identify creative individuals.
B)ignores special talents.
C)ignores the poor adjustment that characterizes such persons.
D)identifies only persons from upper socioeconomic levels.

Using only IQ scores as the measure of giftedness ignores special talents that cannot be measured by IQ tests, such as artistic or athletic abilities.

Question 16

A person with an intellectual disability has an IQ score of approximately 70 or below and has difficulty with _____, such as dressing, eating, communicating, shopping, or working.
A)basic aptitudes
B)kinesthetic skills
C)convergent abilities
D)adaptive behaviors

Accepted Answer

An intellectual disability is defined by not only having a low IQ score, but also by having difficulties with adaptive behaviors, which are the daily living skills needed to function independently in society. These can include dressing, eating, communicating, shopping, or working. Therefore, the best choice is D, adaptive behaviors.

Question 17

The dividing line between normal intelligence and an intellectual disability has traditionally been an IQ of
A)80.
B)70.
C)60.
D)50.

Accepted Answer

An IQ of 70 or below is typically used as the dividing line between normal intelligence and an intellectual disability. This is based on the standard deviations for IQ scores, where approximately 95% of individuals’ scores fall within two standard deviations of the mean score of 100. An IQ score of 70 falls two standard deviations below the mean, which is indicative of significant cognitive limitations.

Question 18

Regarding the identification of giftedness, which of the following statements is/are TRUE?
A)Limiting giftedness to high IQ can shortchange children with special talents.
B)Ethnic minority children may not be recognized as gifted because of subtle biases in standardized intelligence tests.
C)Children with physical disabilities are less likely to be recognized as being gifted.
D)All of these statements are true.

Accepted Answer

All three statements are true. Giftedness should not be limited to high IQ scores as different talents and abilities can manifest in many ways. Standardized intelligence tests may not be culturally sensitive or may contain biases that favor certain groups, resulting in giftedness being recognized less in ethnic minority children. Children with physical disabilities may also face additional barriers in being recognized as gifted.

Question 19

Persons with savant syndrome
A)were geniuses who developed a mental illness during adolescence.
B)have a familial intellectual disability.
C)have exceptional skills in music, math, or remembering names or numbers.
D)are characterized by all of these characteristics.

Accepted Answer

Persons with savant syndrome have exceptional skills in areas such as music, math, or memory, but this ability is often accompanied by intellectual disability or developmental disorders. There is no evidence to suggest that they were geniuses who developed a mental illness or that their condition is familial.

Question 20

Sandra has below normal intelligence but she is able to tell you the exact day of the week for any given day in any given year as well as knowing all the zip codes and area codes in the United States.She has
A)pseudo-giftedness.
B)savant syndrome.
C)Klinefelter's syndrome.
D)a schizotypal personality.

Accepted Answer

Sandra displays abilities that are characteristic of savant syndrome, which is a condition in which an individual with a developmental disorder like autism, has extraordinary abilities in a very specific area, while exhibiting below average intellectual functioning in broad areas that are unrelated to the specific skill. In Sandra's case, she has the ability to perform complex calendrical calculations and recall all US zip codes and area codes, while having below normal intelligence.
