Children adopted into enriching environments have been shown to improve their IQ by how many points compared to siblings who remained in impoverished environments?

The correct answer highlights research findings that indicate children adopted into nurturing and stimulating environments can experience significant cognitive improvements, specifically an increase in IQ scores. Studies have shown that these children may gain around 14 IQ points compared to their siblings who remain in underprivileged circumstances.

This improvement is attributable to various factors present in enriching environments, such as access to educational resources, supportive relationships, and a stimulating atmosphere that fosters cognitive development. Engaging with diverse experiences and receiving emotional and instructional support are key elements that contribute to this increase in intellectual capability.

The research underscores the impact that environment can have on cognitive development, illustrating that early life experiences play a crucial role in shaping intellectual outcomes. This knowledge is valuable for understanding the interplay between heredity and environment in psychological development.
