A2013 study (luby, et al) looked at three variables that mediate the impact poverty on hippocampus volume: parental education, parenting style and stressful life events. they found that parental education was not correlated with hippocampus volume. this finding was important because in this study, the variable, "parental education," served as a proxy for intelligence, an individual differences variable which is considered to have a genetic component. the lack of a relationship ruled out a rival hypothesis that the size of a child's hippocampus is

the result of inherited ability

Explanation:

Inherited ability refers to the type of ability that can be passed by the parents to the children through genetics.

If the size of hippo campus is determine by genetic,children that are born from intelligent parents should be guaranteed to also have bigger hiccoughs. Since there is no correlation between the two, we can conclude that environmental factors play a crucial role in determining the size of hippocampus.
