b. to compare the intelligence levels of children to their parents.
c. testing Galton’s psychophysics performance theory.

b. 50% of the population will have average intelligence.
c. 50% of all differences of variabilities observed in a population’s intelligence test scores due to genetic factors.

7. Which states the MOST important difference between Gardner’s and Sternberg’s theories of multiple intelligence?
a. Gardner delineated at least nine types of intelligence whereas Sternberg considered
three types.
b. Gardner linked his theory to knowledge about parts of the brain whereas Sternberg did not consider brain function.
c. Gardner described a number of independent intelligences, whereas Sternberg described
three interacting components.
d. Gardner described his intelligences based on what people could do whereas Sternberg focused on how people did what they did.
8. Which of the following is the MOST consistent sign of intellectual disability?

a. Individuals in racial minority groups tend on average to have lower IQs than individuals
in the majority population.
b. Racial minority children are treated very differently in schools than other children. This bias in the environment restricts their performance on IQ tests.
c. Racial minorities tend to have lower socio-economic status and are often living in a
deficient environment which restricts their performance on IQ tests.
