Study Notes
Heritability
- Individual behavior and thinking patterns are influenced by a mix of genetic makeup and environmental factors.
The Flynn Effect
- A significant increase in average intelligence test scores observed over time across populations.
Explanations for the Flynn Effect
- Possible reasons for the Flynn Effect include:
- Improved nutrition
- Decreased prevalence of infectious diseases
- Enhanced access to and quality of education
- More stimulating living environments
Relative Intelligence vs Actual Intelligence
- Relative Intelligence remains constant over time, while Actual Intelligence tends to decline as individuals age.
Crystalized Intelligence
- Involves the use of acquired knowledge and factual information, such as knowing state capitals or historical figures.
- Individuals with high crystallized intelligence are often referred to as having "book smarts."
Fluid Intelligence
- Refers to the capacity to solve novel problems and adapt quickly in unfamiliar situations.
- Often associated with "street smarts," highlighting practical problem-solving abilities.
Factors Influencing Intelligence in Wealthier Families
- Wealthier families can:
- Invest more resources into education.
- Access higher educational levels, improving their children’s knowledge.
- Engage in broader social networks, enhancing opportunities and connections.
Influence of Nutrition on Infant IQ
- Infants who are breastfed are statistically found to have higher IQs compared to those fed formula.
Lewis Terman's Controversial Views
- Known for promoting the idea that intelligence varies among races, displaying racist attitudes regarding IQ differences among Black, Caucasian, and Asian populations.
Enhancing Neural Change
- Important practices for promoting neural development and cognitive function include:
- Adequate sleep
- Regular exercise
- Proper nutrition
