Question

How would you test the claim that 80% of a child's intelligence comes from their mum? (4pts)

a) Conduct a twin study comparing maternal and paternal influence
b) Analyze the heritability of specific intelligence genes
c) Assess the environmental factors in the child's upbringing
d) Examine the correlation between maternal intelligence and the child's IQ score

Answer 1

To test the claim that 80% of a child's intelligence comes from their mother, twin studies, analysis of specific genes, and examining the correlation between maternal intelligence and the child's IQ score can be used.

Step-by-step explanation:

To test the claim that 80% of a child's intelligence comes from their mother, several approaches can be taken:

1. Conduct a twin study comparing maternal and paternal influence: Identical twins raised together and apart can be studied to compare the similarity in their IQ scores, which can provide insight into the influence of genetics.
2. Analyze the heritability of specific intelligence genes: By studying specific genes associated with intelligence, researchers can determine their heritability and contribution to a child's intelligence.
3. Examine the correlation between maternal intelligence and the child's IQ score: By assessing the correlation between the IQ scores of mothers and their children, researchers can explore the influence of maternal intelligence on a child's intelligence.
