Question 1

Research would predict that _____ would show the largest intellectual declines in the coming years.

Accepted Answer

Research has consistently shown that social engagement is a protective factor against cognitive decline in older adults. Therefore, option B, where Grace lives alone and is socially inactive, is the most likely to show intellectual declines in the coming years.

Question 2

Longitudinal research on IQ change during adulthood indicates that

Accepted Answer

Longitudinal research on IQ change during adulthood indicates that fluid intelligence peaks and then declines, while crystallized intelligence remains steady well into adulthood.

Question 3

Who will likely have the highest IQ?

Accepted Answer

Microbiology is a highly specialized field that requires advanced knowledge and skills in sciences, mathematics, and critical thinking. Therefore, Reena, who is a microbiologist, is likely to have a higher IQ compared to Jose, Sandy, or Parker, who perform jobs that may not require the same level of intellectual abilities.

Question 4

Which of the following is true of creative children?

Accepted Answer

Research has consistently shown that creative children engage in more fantasy or pretend play than less creative children. This type of play allows for exploration and imagination, which are important components of creativity.

Question 5

Which statement is true?

Accepted Answer

During adolescence, IQ scores tend to stabilize and become more predictable, reflecting a consolidation of cognitive abilities. However, creativity can show significant variation during this period as adolescents explore different aspects of their identity and interests.

Question 6

Which is the best definition of wisdom?

Accepted Answer

Wisdom is often associated with expert knowledge and practical expertise in navigating life's challenges and solving complex problems. It requires more than just intelligence and creativity, and cannot be fully captured by a high IQ score. The ability to generate novel solutions is an important aspect of creativity, but wisdom involves knowing which solutions are most practical and effective given the circumstances.

Question 7

The cumulative-deficit hypothesis is often used to explain

Accepted Answer

The cumulative-deficit hypothesis suggests that the negative effects of an impoverished environment, such as poor nutrition and lack of stimulation, accumulate over time to create lowered cognitive abilities and IQ scores. This can have a long-term impact on educational outcomes and future success.

Question 8

The Flynn effect refers to the observation that

Accepted Answer

The Flynn effect refers to the phenomenon of average IQ scores increasing over time, which cannot be explained by genetic changes.

Question 9

Research on aging and creativity has shown that older individuals are _____ than younger adults.

Accepted Answer

Research indicates that while older individuals can be as original in their thinking as younger adults, they tend to be less productive in generating creative ideas. This suggests that the capacity for original thought does not diminish with age, but the quantity of creative output might decrease.

Question 10

Which "home environment" factor seems to be most important for the intellectual development of a child?

Accepted Answer

Parental involvement with the child has consistently been found to be the most important factor in a child's intellectual development. Parents who actively engage with their child through talking, reading, and other educational activities have been shown to have children with higher cognitive abilities and academic success. Having siblings or a particular parenting style may have some influence, but they are not as consistently impactful as parental involvement.

Question 11

IQ scores obtained during adolescence are best at predicting

Accepted Answer

IQ scores are most effective at predicting academic performance, such as high school grades, because they measure cognitive abilities that are directly related to learning and problem-solving skills used in educational settings.

Question 12

Which of the following can we conclude about intellectual functioning across the lifespan?

Accepted Answer

Research has consistently shown that processing speed is related to intellectual performance. Those who are able to quickly and accurately process information tend to have higher levels of intellectual functioning.

Answer: D 
 Age-related declines in intellectual ability are not universal. While some decline may occur, the rate and extent of decline can vary greatly among individuals. Factors such as education, lifestyle, and genetics can all influence the degree of decline.

Question 13

Who will likely have the lowest IQ?

Accepted Answer

IQ does not correlate with occupation, making this question misleading. However, the question seems to imply a stereotype that manual or trade jobs (like a pipe fitter) require less intelligence than professional or academic jobs. This is a false and harmful stereotype. Intelligence varies widely within all professions and cannot be accurately predicted based on occupation alone.

Question 14

Which statement best describes the impact of genetics and environment on a child's IQ?

Accepted Answer

Research has shown that both genetics and environment play a role in a child's development of intelligence. At age two, maternal IQ has a stronger impact on a child's IQ than the quality of the home environment. However, by age four, the quality of the home environment becomes just as important a predictor of a child's IQ as maternal IQ. This suggests that both genetic and environmental factors are important in shaping a child's intelligence.

Question 15

Research on wisdom suggests that

Accepted Answer

Research suggests that wisdom is closely related to expertise and experience in a particular domain. While age may contribute to wisdom to some extent, it is not necessarily a predictor of wisdom. Personality traits such as openness to experience and emotional stability may also play a role in the development of wisdom. Intelligence may be a factor, but it is not as strongly tied to wisdom as expertise and experience. Therefore, option B is the best choice.

Question 16

Peak levels of creativity tend to occur EARLIEST in individuals who are in the

Accepted Answer

Peak levels of creativity tend to occur earliest in individuals who are in the arts. This is because the arts are typically associated with abstract and imaginative thinking, which is conducive to creative problem-solving and ideation. Additionally, many artists begin their careers at young ages, honing their skills and developing their creativity over time. However, it's important to note that creativity can emerge in individuals across all fields and disciplines.

Question 17

Research on changes in intellectual abilities during adulthood indicates that

Accepted Answer

Research has consistently shown that fluid intelligence, or the ability to reason and solve problems in new situations, declines earlier and more quickly than crystallized intelligence, or the knowledge and skills gained through education and experience. Crystallized intelligence may even continue to increase into middle adulthood before eventually seeing a decline in later life.

Question 18

A researcher is using a measure in which both the emotional and verbal responsiveness of a parent and the provision of appropriate play materials are being assessed.Given this description,the researcher appears to be using the

Accepted Answer

The HOME inventory (Home Observation for Measurement of the Environment) assesses the quality and quantity of stimulation and support provided by a child's home environment, including both emotional and verbal responsiveness and appropriate play materials. The other measures listed do not specifically assess these aspects of the home environment.

Question 19

Children from impoverished environments may show progressively lower IQ scores over time,a phenomenon called

Accepted Answer

The phenomenon in which children from impoverished environments show progressively lower IQ scores over time is called cumulative-deficit. This refers to the idea that the effects of deprivation add up over time, leading to a widening gap in cognitive abilities between children from low-income families and their more advantaged peers. Terminal drop refers to a sudden and dramatic decline in cognitive abilities in older adults, savant syndrome is a rare condition in which individuals with developmental disabilities exhibit exceptional skills in a specific area, and factor analysis is a statistical method used to explore relationships between variables.

Question 20

The fact that adults born in the 1980s have higher adult IQs than adults born in the 1950s illustrates the _____ effect.

Accepted Answer

The Flynn effect refers to the worldwide phenomenon of IQ scores increasing over time, particularly in the 20th century. The increase in IQ scores is not due to genetic factors, but rather environmental ones such as improved education, access to information, and technology. This is demonstrated by the fact that adults born in the 1980s have higher adult IQs than adults born in the 1950s, which suggests that something in the environment is causing this increase. The other options are not relevant to this increase in IQ scores.
