10 Questions
What was the surprising finding from the study on mouse twins separated when young?
There was no interaction effect between genes and environment.
What is the best explanation for the lack of gene-environment interaction effect, according to the text?
The Transactional Model of cognitive development.
According to the Transactional Model of cognitive development, what is the relationship between genes and environment?
Children select and evoke experiences in line with their genetic predispositions, leading to a snowball effect.
What is the proposed mechanism behind the snowball effect described in the text?
Children actively choose environments that align with their genetic predispositions, amplifying their cognitive development.
What is the relationship between socioeconomic status and heritability of cognitive abilities?
Heritability is higher in rich families than in poor families.
What is proposed as a potential explanation for the differences in heritability across socioeconomic levels?
Gene-environment interactions (GxE) and active gene-environment correlations (rGE).
What is the relationship between genes and environments in human development?
Children are born with all of their genes, and as they grow, they experience more and more environments.
Which of the following is NOT a proposed mechanism for gene-environment interactions, according to the text?
The Additive Model of cognitive development.
What is the significance of the finding that heritability differs across socioeconomic levels?
It indicates that gene-environment interactions play a role in cognitive development.
Based on the information provided in the text, which of the following statements is accurate?
Children select and evoke experiences in line with their genetic predispositions.
Test your knowledge on passive genotype-environment correlation and how genetic predispositions can influence the environment in related individuals. Learn about the impact of genetic factors on creating both positive and negative environments in households.
