Drs. Snyder, Waldman, Plomin, and Haden all conduct twin-design Behavioral Genetics studies of IQ. Drs. Snyder and Waldman's datasets are of young children; Drs. Plomin and Haden's datasets are of older adults. Further, Drs. Waldman and Plomin's datasets were collected in poorer neighborhoods. Drs. Snyder and Haden's datasets were collected in wealthier neighborhoods. Which of the following is MOST likely to happen? A.Compared to her colleagues, Dr. Plomin will likely conclude that the genetic contributions to IQ is highest. B.Compared to her colleagues, Dr. Plomin will likely conclude that the environmental contributions to IQ is highest. C.Compared to her colleagues, Dr. Haden will likely conclude that the environmental contributions to IQ is highest. D.Compared to her colleagues, Dr. Haden will likely conclude that the genetic contributions to IQ is highest.

B. Compared to her colleagues, Dr. Plomin will likely conclude that the environmental contributions to IQ is highest This is because Dr. Plomin worked with participants of lower SES which is a major environmental factor associated with IQ. D. compared to her colleagues, Dr. Haden will likely to conclude that the genetic contributions to IQ is the highest. This is the correct answer because (a) Lower socio-economic status is a factor which also determines a person's intelligence and Dr. Haden chose high socio-economic status candidates. (b) Dr. Haden chose older adults to determine the heritability of intelligence. It has been proven that with increase in age the heritability of intelligence also increases. Therefore, he will be better able to prove that genetic contributions to IQ is the highest. A is incorrect because Dr. Plomin chose participants from poor neighborhood and SES is an environmental factor for IQ which means that his conclusion would not show higher genetic contributions but higher environmental contributions. C is incorrect because Dr. Haden worked with richer participants hence he would not be able to conclude that.
