The relationship between IQ and age has been a subject of extensive research, with various studies examining how IQ changes over the lifespan. This synthesis aims to present key insights from multiple research papers to address whether IQ varies with age.
Heritability of IQ Increases with Age:
IQ Stability Over Time:
Age-Related Changes in IQ:
Sex Differences in IQ Over Time:
Generational Changes in IQ (Flynn Effect):
Differentiation of Cognitive Abilities:
In summary, while IQ shows significant stability over the lifespan, its heritability increases with age, and shared environmental influences decrease. There are age-related changes in specific cognitive tasks, and sex differences in IQ can emerge over time. Generational changes in IQ, known as the Flynn Effect, also vary by age and ability level. Overall, these findings suggest that while IQ remains relatively stable, there are nuanced variations influenced by age, sex, and generational factors.
