Understanding IQ Scores in Context of Socio-Economic Status
The question revolves around the relationship between socio-economic status and IQ scores, particularly in the context of identical twins who are raised in contrasting environments.
Key Factors Influencing IQ
- Genetic Influence: Since the twins are identical, they share the same genetic makeup, which plays a significant role in determining IQ. This genetic predisposition suggests that their IQ scores may not differ drastically solely based on environmental factors.
- Environmental Factors: While socio-economic status can influence educational opportunities, access to resources, and stimulation, these factors do not completely negate the genetic similarities. In the case of identical twins, the genetic contribution is a strong factor in their IQ.
Socio-Economic Status and Its Effects
- Variability in Development: Although children from wealthier families often have access to better educational resources and cognitive stimulation, the immediate impact on IQ scores within a year may not be significant. Developmental changes take time, and one year may not be sufficient to observe drastic differences in IQ.
- Potential for Underestimation: The boy from the poor family may benefit from resilience and other adaptive skills, while the boy from the wealthy family may not necessarily outperform him in IQ tests.
Conclusion
Given these factors, the correct answer (option B) implies that socio-economic level does not significantly affect IQ scores in identical twins within a year. The genetic similarity provides a strong foundation for comparable IQ scores, regardless of their different socio-economic environments.
