Question 1

Intelligence is positively associated with longevity.

Accepted Answer

Studies have shown that higher intelligence scores are associated with a lower risk of death, suggesting a positive association between intelligence and longevity. This relationship may be due to a variety of factors, including better health behaviors, more effective disease management, and socioeconomic advantages linked to higher intelligence.

Question 2

Your text reports that in the early years of the 20th century, advocates for the disadvantaged argued that good education can lift the IQ scores of the disadvantaged. In light of subsequent research, were the advocates correct

Accepted Answer

Research has shown that education can have a significant impact on IQ scores. A lack of schooling can indeed result in declines in IQ, indicating that the environment, including educational opportunities, plays a crucial role in intellectual development.

Question 3

The aspect of emotional intelligence that is most strongly supported by empirical research is emotional __________.

Accepted Answer

Emotional regulation, which refers to the ability to manage and respond to an emotional experience with a range of strategies, is the aspect of emotional intelligence most strongly supported by empirical research. This includes research on how individuals control and modify their own emotions, as well as how they influence the emotions of others, which has significant implications for personal well-being and interpersonal relationships.

Question 4

The notion that practical intelligence is separate from g is well-supported empirically.

Accepted Answer

Practical intelligence, often associated with "street smarts" or the ability to handle everyday tasks, is not empirically supported as a construct separate from general intelligence (g). Most research in psychology suggests that practical intelligence correlates with measures of general intelligence, indicating it may not be a distinct form of intelligence.

Question 5

Studies comparing identical and fraternal twins reveal that:

Accepted Answer

Studies show that identical twins have a more highly correlated intelligence scores than fraternal twins, indicating that genetics play a significant role in intelligence.

Question 6

Charles Spearman developed the first intelligence test.

Accepted Answer

Alfred Binet and Theodore Simon developed the first practical intelligence test in 1905, not Charles Spearman.

Question 7

The ability to regulate one's emotions is positively associated with:

Accepted Answer

The ability to regulate one's emotions is crucial for various aspects of well-being and success, including academic performance (like SAT scores), social interactions (hence, higher ratings of social skills), and managing challenging situations (such as coping with frustration). Emotional regulation helps individuals navigate their feelings in ways that are productive and healthy, impacting these areas positively.

Question 8

A persisting issue or controversy in psychology that is especially relevant to the study of intelligence is that of:

Accepted Answer

The nature vs. nurture debate is especially relevant to the study of intelligence as it concerns the extent to which intelligence is a product of genetic inheritance (nature) or influenced by environmental factors (nurture).

Question 9

Intelligence is found primarily in the

Accepted Answer

Intelligence is primarily associated with the cortex, especially the prefrontal cortex, which is involved in complex cognitive behaviors, personality expression, decision making, and moderating social behavior.

Question 10

Which of the following interpretations is consistent with the correlation between intelligence scores and the number of neurons in the brain

Accepted Answer

Correlations indicate a relationship between two variables but do not establish causation. Each of the interpretations (A, B, C) suggests a plausible link between intelligence scores and the number of neurons, fitting the concept that correlation can be consistent with multiple causal interpretations.

Question 11

Psychologists use the term divergent thinking to refer to the ability to generate new solutions to problems.

Accepted Answer

Divergent thinking is a thought process or method used to generate creative ideas by exploring many possible solutions. It involves thinking in a non-linear manner to explore different avenues and create multiple solutions for a given problem.

Question 12

Which of the following pairs of correlation coefficients most closely corresponds to the observed correlations between the intelligence scores of adopted children and those of their adoptive or biological parents

Accepted Answer

Research generally shows that the correlation between adopted children's intelligence scores and those of their biological parents is higher than the correlation between adopted children's intelligence scores and those of their adoptive parents. This suggests a genetic component to intelligence. Option A reflects this pattern, with a higher correlation to biological parents (0.40) than to adoptive parents (0.20).

Question 13

Which of the following is the best evidence for a genetic contribution to intelligence

Accepted Answer

The fact that intelligence scores of identical twins (who share 100% of their genes) tend to be more similar than those of fraternal twins (who share on average 50% of their genes) provides strong evidence for a genetic contribution to intelligence. This comparison controls for environmental factors to a large extent, as both types of twins typically grow up in the same environment.

Question 14

Which of the following is NOT among the criticisms that have been levied against emotional intelligence and the tests that claim to measure it

Accepted Answer

Criticisms of emotional intelligence and its measurement often focus on its predictive validity for job performance (A), the nature of what is being assessed (knowledge vs. application of emotions, B), and debates about its classification as a type of intelligence or a personality trait (D). The claim that people higher in emotional intelligence are no healthier than those lower in it (C) is not a common criticism in the literature, as emotional intelligence is often linked to better mental health and well-being.

Question 15

The most widely used test of adult intelligence is the WAIS-IV.

Accepted Answer

The WAIS-IV, or Wechsler Adult Intelligence Scale - Fourth Edition, is indeed the most widely used intelligence test for adults, assessing various aspects of intelligence and cognitive ability.

Question 16

The ability to identify, assess, manage, and control one's emotions is known as

Accepted Answer

Emotional intelligence refers to the capacity to be aware of, control, and express one's emotions, and to handle interpersonal relationships judiciously and empathetically.

Question 17

Recall your text's discussion of emotional intelligence. The ________ of a measure of emotional intelligence would be supported by positive correlations between scores on the measure and scores on a measure of Gardner's _______ intelligence.

Accepted Answer

Emotional intelligence is closely related to Gardner's interpersonal and intrapersonal intelligences. Interpersonal intelligence involves understanding and interacting with others, while intrapersonal intelligence involves understanding oneself. Both are aspects of emotional intelligence, which deals with recognizing, understanding, and managing emotions in oneself and others. Therefore, a measure of emotional intelligence would be considered valid if it correlates positively with measures of these types of intelligence.

Question 18

The New York Times crossword puzzle draws primarily on crystallized intelligence.

Accepted Answer

Crystallized intelligence refers to the use of knowledge that comes from prior learning and past experiences, which is exactly what solving crossword puzzles, like those in The New York Times, relies on.

Question 19

Angie is computing the correlation between the intelligence test scores and the household incomes of a large sample of American adults. What type of correlation should she find

Accepted Answer

Angie is likely to find a positive correlation between intelligence test scores and household incomes, as research often shows that higher levels of education and intelligence can lead to higher-paying jobs, which in turn can lead to higher household incomes.

Question 20

A researcher finds a significant correlation between the IQ scores and the socioeconomic status (SES) of a large sample of American adults. Which of the following can she conclude

Accepted Answer

The researcher can conclude that there is a relationship between SES and IQ (C), but cannot determine causality (i.e., whether one causes the other) based solely on a correlation.
