Question 1

_________ was heavily influenced by the introduction of intelligence tests,and refers to the belief that some individuals have "superior" genes than others.
A)Stereotype threat
B)Anthropometrics
C)Eugenics
D)Ravens Progressive Matrices

Accepted Answer

Eugenics was heavily influenced by intelligence tests, which claimed to measure innate intelligence and ability. Eugenicists believed in the existence of "superior" genes and advocated for selective breeding to improve the genetic quality of the human race. This belief system led to the forced sterilization and persecution of certain groups, including people with disabilities and minorities.

Question 2

What does the Flynn effect refer to?
A)the increase in average IQ test scores over decades
B)the decrease in average IQ test scores over decades
C)the higher IQ test average scores for Asian Americans compared to European Americans
D)the lower IQ test average scores for African Americans compared to European Americans

Accepted Answer

The Flynn effect refers to the increase in average IQ test scores over decades.

Question 3

Using the original formula for the intelligence quotient,an 8-year-old child with a mental age of 10 would have an IQ that
A)is exactly 100.
B)is greater than 100.
C)is less than 100.
D)cannot be determined without more information.

Accepted Answer

The original formula for IQ is (mental age/chronological age) x 100. In this case, the child's mental age is greater than their chronological age, so their IQ would be greater than 100. Specifically, (10/8) x 100 = 125.

Question 4

Which of the following statements is true about the relationship between brain size and some aspects of intelligence?
A)Brain size is moderately related to intelligence.
B)There is no relationship between brain size and intelligence.
C)Brain size is an almost perfect predictor of intelligence.
D)The number and size of cerebral gyri,but not overall brain size,are related to intelligence.

Accepted Answer

Brain size is moderately related to intelligence. While brain size is not the only factor that determines intelligence, larger brains do tend to be associated with higher intelligence. However, it is important to note that there are many other factors that contribute to intelligence such as neuroplasticity, neural connectivity, and environmental factors.

Question 5

Hussein is a small business owner.He was a C student in school and does not generally think of himself as very "smart." Nonetheless,Hussein does an excellent job of running his business and dealing intelligently with real -world problems when they arise.According to the triarchic theory of intelligence,which type of intelligence is Hussein demonstrating?
A)creative
B)analytical
C)crystallized
D)practical

Accepted Answer

Hussein is demonstrating practical intelligence, which involves being able to apply one's knowledge and skills to real-world settings and effectively deal with practical problems. This type of intelligence is not necessarily associated with academic achievement or traditional measures of intelligence, but rather with the ability to adapt to and thrive in real-world situations.

Question 6

Which of the following is the best psychological definition of intelligence?
A)how much information an individual can correctly recall
B)the ability to think,understand,reason,and cognitively adapt to obstacles
C)an individual's score on a standardized intelligence test
D)the ability to quickly and efficiently learn new material in an unknown environment

Accepted Answer

Intelligence is not just about memorizing and recalling information, but also about the ability to think critically, understand complex concepts, reason logically, and adapt to unfamiliar or challenging situations. Intelligence tests may be a measure of certain aspects of intelligence, but they are not the only or definitive measure. Being able to learn quickly in a new environment is also a component of intelligence, but it is not the sole definition.

Question 7

Which of the following statements supports the theory that intelligence is determined in part by genes?
A)The correlation between IQ scores is stronger for fraternal twins than it is for identical twins.
B)Diet and lifestyle factors have a substantial influence on intelligence.
C)Offspring raised by their biological parents are more similar to them than when they are raised by foster parents.
D)Identical twins separated by adoption still have highly correlated IQ scores.

Accepted Answer

Identical twins share 100% of their genes, and if they have highly correlated IQ scores even when separated by adoption, it suggests that genes play a significant role in determining intelligence.

Question 8

Carla is asked to take a math test by a job placement company.As she sits down to take the test,Carla begins to think about how women are often viewed as being worse at math than men.These thoughts cause Carla to experience discomfort and anxiety during the test,which then have a negative impact on her test result.Carla's dilemma is an example of what psychologists call
A)the Flynn effect.
B)covert discrimination.
C)stereotype threat.
D)confirmation bias.

Accepted Answer

Carla's anxiety and discomfort during the math test were caused by thoughts related to a stereotype about women's ability in math. This is known as stereotype threat, which is the phenomenon where individuals experience anxiety and negative emotions, and perform worse on tasks, when they are aware of negative stereotypes about the group to which they belong.

Question 9

Differences between men and women on mental rotation and verbal fluency tests may reflect differences in _____ levels in the brain.
A)testosterone
B)estrogen
C)serotonin
D)dopamine

Accepted Answer

Testosterone is a hormone found in higher levels in males than females and has been linked to spatial abilities such as mental rotation. Estrogen, serotonin, and dopamine have not been consistently linked to sex differences in these abilities.

Question 10

Whereas _____ intelligence tends to decrease in later life,_____ intelligence generally does not decline,and may even continue to increase.
A)general;crystallized
B)general;fluid
C)crystallized;fluid
D)fluid;crystallized

Accepted Answer

Fluid intelligence refers to the ability to solve problems and think abstractly, which tends to peak in early adulthood and gradually declines with age. On the other hand, Crystallized intelligence refers to the accumulation of knowledge and skills through experience and education, which tends to increase or remain stable throughout adulthood. Therefore, choice D is the best fit as it correctly reflects that fluid intelligence tends to decrease with age, while crystallized intelligence generally does not decline and may continue to increase.
