Professor Ernie wants to first develop an intelligence test that can be used cross-culturally, and then to assess the reliability and validity of that test. Briefly explain how Professor Ernie could examine the following characteristics about this new intelligence test • Standardization • Reliability • Validity • Bias

Provide three pieces of evidence that explain why more intelligent people might live longer.

The principal of a new elementary school wants to give an IQ test to all students when they enter the school. The students will then be placed in groups of students with similar IQ scores. The principal assures the community that this plan is supported by scientific research and will improve education for all students, regardless of their ability. • Using evidence, present an argument for or against intelligence testing for children early in life. • Using evidence, present an argument for or against schools that "track" children based on intelligence test scores, separating high scorers from those with lower scores. • Using evidence, present an argument supporting the claim that environmental influences affect intelligence. • Using evidence, present an argument supporting the claim that labeling or tracking students could lead to stereotype threat.

Piaget, Erikson, and Kohlberg described several cognitive, social, and moral reasoning stages of adolescence. Illustrate each of the following stages. Concrete operational; Formal operational; Identity versus role confusion; Intimacy versus isolation; Conventional level; Postconventional level.

If a test yields consistent results upon retesting, it can be said to have a high degree of a. reliability. b. validity. c. content validity. d. predictive validity. c. normal curve.

A school counselor wants to know how smart the students in her school are. She gets funding from the principal to give an IQ test to an SRS of 60 of the over 1000 students in the school. The mean IQ score was 114.98 and the standard deviation was 14.80. Construct a 90% confidence interval for the mean IQ score of students at the school.

Numerous biological, psychological, and social-cultural factors affect the way we age. Explain one example for each of the three that contributes to successful aging.

In the 1980s, a study linked coffee to a higher risk of heart disease and pancreatic cancer. In the early 1990 s, studies showed that drinking coffee posed minimal health threats. However, in 1994, a study showed that pregnant women who drank 3 or more cups of tea daily may be at risk for miscarriage. In 1998, a study claimed that women who drank more than a half-cup of caffeinated tea every day may actually increase their fertility. In 1998, a study showed that over a lifetime, a few extra cups of coffee a day can raise blood pressure, heart rate, and stress (Source: "Bottom Line: Is It Good for You? Or Bad?" by Monika Guttman, USA TODAY Weekend). Propose some reasons why these studies appear to be conflicting.

Which of the following can be used to demonstrate that only about 2 percent of the population scores at least two standard deviations above the mean on an intelligence test? a. Reliability test. b. Aptitude test. c. Predictive validity test. d. Test-retest procedure. e. Normal curve.

Researchers studying the effects of genes on intelligence have found that a. intelligence is affected by many genes working together. b. there is a gene that is involved in the intelligence of men but not women. c. there is a gene that is involved in the intelligence of women but not men. d. a single gene is involved in the intelligence of both men and women. e. there is no evidence that genes play a role in intelligence.

Shervin is a high school student who excels in academics and usually scores very high on academic standardized tests. His friend, Hany, struggles in his coursework and with standardized tests, but is a brilliant pianist and dancer. For each of the following psychologists, briefly explain his theory and identify how that psychologist might describe Shervin's and Hany's intelligence. • Howard Gardner • Robert Sternberg • Charles Spearman
