Quizplus · Accepted Answer

Aamina is participating in an adoption study, because her IQ is being compared with both her adoptive and biological parents' IQs, which is a common method used in adoption studies to examine the influence of nature vs nurture on intelligence. Option A is incorrect because twin studies examine the heritability of traits in identical twins. Option B is incorrect because correlational studies measure the relationship between variables, which may not be relevant in this case. Option C is incorrect because heritability studies estimate the proportion of variation in a trait that is due to genetic factors.
