Longitudinal evidence showed modest gains in midlife 50s & early 60s where gradually decline. Using a sequential design, schaei found cross-sectional, steep drop-off largely due to cohort effects as each new generation experienced better health & education.

Measured by general info, verbal compression & logical reasoning on intelligence tests. Fluid intelligence: depends on basic information-processing skills (ability to detect relationships among visual stimuli, speed of analyzing info, & capacity of working memory) Begins to decline in 20s & influenced by brain condition & unique learning.
