The relationship between age and IQ has been a subject of extensive research. Various studies have explored how IQ changes over the lifespan, considering factors such as genetics, environment, and health. This synthesis aims to present key insights from multiple research papers to address whether IQ increases with age.
Heritability and Stability of IQ with Age:
Early Life IQ and Later Life Outcomes:
Sex Differences in IQ Over Time:
IQ and Cognitive Abilities in Special Populations:
Impact of Health and Growth on IQ:
The research indicates that while the heritability of IQ increases and stabilizes in late adolescence, the overall IQ tends to remain stable throughout adulthood. Early-life IQ has significant implications for later life outcomes, including mental and physical health. There are also notable sex differences in IQ development, and specific cognitive abilities may improve with age in certain populations. Overall, IQ does not generally increase with age, but early cognitive abilities play a crucial role in shaping future outcomes.
