Longitudinal research is the best choice because it follows the same individuals over time, allowing for a comparison of their cognitive ability at different ages. This provides a more accurate assessment of cognitive changes with age, as opposed to cross-sectional research which compares individuals of different ages at a single point in time. Research on fluid intelligence, which is the ability to think logically and solve problems in novel situations, has also challenged the idea of age-related decline in intelligence, as it tends to remain relatively stable throughout adulthood. Tests assessing recall memory may show declines in specific cognitive abilities with age, but do not necessarily reflect overall intelligence.
