The high correlation between the IQs of identical twins raised in different environments supports the role of genetics (nature) in IQ development.
View all questions of this testWhich of the following statements supports the role of environments in...
Correlation between IQs of identical twins raised in different homes is as high as 0.75
Identical twins share 100% of their genetic material, making them ideal subjects for studying the influence of genetics and environment on development. The fact that the correlation between their IQs remains high even when raised in different environments suggests that genetics play a significant role in intelligence. However, the correlation is not perfect, indicating that environmental factors also have an impact on IQ.
Explanation:
- The statement highlights the importance of genetics in determining intelligence, as evidenced by the high correlation between the IQs of identical twins.
- It also acknowledges the role of environments in shaping a child's development, as the correlation is not 1.0, indicating that environmental factors play a part in intelligence.
- This finding underscores the complex interplay between genetics and environments in the development of a child, emphasizing the need to consider both factors when studying cognitive abilities.
In conclusion, the statement supports the role of environments in the development of a child by demonstrating that while genetics play a significant role in intelligence, environmental factors also contribute to a child's cognitive abilities.
