Phase One: Cross-Sectional Evidence
for Intellectual Decline


Cross-sectional Study: A study in which
people of different ages are compared with
one another
Researchers found that older adults give
fewer correct answers than do younger
adults in intelligence tests.
Phase Two: Longitudinal Evidence for
Intellectual Stability


Longitudinal Study: Research in which the
same people are restudied and retested over
a long period.
Researchers found that intelligence
remained stable until late in life and even
increased in some tests
Phase Three: It All Depends


Crystallized Intelligence: One's accumulated
knowledge as reflected in vocabulary and
analogies tests; increases with age.
Fluid Intelligence: One's ability to reason
speedily and abstractly, as when solving
novel logic problems; tends to decrease
during late adulthood.
Conclusion

We lose recall memory and processing
speed, but we gain vocabulary and
knowledge
