Flynn effect Flashcards
Improved Education and Access to Information
Rindermann, H. (2008)
Increased access to education and information may lead to better cognitive skills and problem-solving abilities
Historical data showing increased school enrollment and literacy rates over time Rindermann, H. (2008)
Environmental Enrichment
Campbell, F. A., (2002)
Changes in the environment, such as more intellectually stimulating activities and technology, could promote cognitive development
Studies demonstrating the positive effects of enriched environments on cognitive development in children, such as the Abecedarian Project Campbell, F. A., (2002)
Health and Nutrition
Grantham-McGregor, S., et al (2007).
Improved nutrition and healthcare over the past century may have positively impacted brain development and cognitive function
Research linking malnutrition during critical periods of development to cognitive deficits
Grantham-McGregor, S., et al (2007).
Changes in Family Structure and Parenting Practices
Bornstein, M. H., Bradley, R. H., & Tamis-LeMonda, C. S. (Eds.). (2014)
Shifts in family dynamics and parenting styles could influence intellectual development
Analysis of longitudinal data showing associations between family factors (e.g., parental education, family size) and child IQ
Bornstein, M. H., Bradley, R. H., & Tamis-LeMonda, C. S. (Eds.). (2014)
Technological Advancements and Cognitive Demands
Jones, G., & Schneider, W. J. (2006)
The increasing complexity of modern society, driven by technological advancements, may require higher cognitive abilities
Studies have found correlations between IQ gains and the complexity of modern societies. However, it’s challenging to establish a direct causal link between technological advancements and IQ increases
Jones, G., & Schneider, W. J. (2006)
Selective Migration and Assortative Mating
Conley, D., & Glauber, R. (2006)
Changes in population demographics, such as selective migration and assortative mating (individuals with similar traits choosing each other as partners), could contribute to IQ gains
Longitudinal studies tracking changes in population demographics and cognitive outcomes over time
Conley, D., & Glauber, R. (2006)
Reverse flynn effect
There isn’t definitive evidence but there are debates and concerns about potential factors that could lead to cognitive decline or stagnation in certain populations or contexts
These factors might include changes in educational quality, environmental pollutants, lifestyle factors, or even the impact of excessive screen time and digital distractions
