Hypothesis

Does education associate with better retention of cognitive abilities from adolescence to older adulthood?

Conclusion

Cognitive abilities remain stable from adolescence to older adulthood, and education has varying benefits based on initial cognitive levels and sex.

Supporting Evidence

  • Cognitive abilities were assessed 58 years apart.
  • Education predicted higher cognitive ability in older age.
  • The effect of education on cognitive ability was diminished for those with higher initial cognitive scores.
  • The benefits of education varied by sex.

Takeaway

This study shows that what you learn in school helps you think better when you're older, but it helps some people more than others.

Methodology

The study used confirmatory factor analysis and structural equation modeling to assess cognitive abilities over time.

Participant Demographics

Participants were aged 71 to 79, with data collected from both men and women.
