They had multiple cohorts: groups of people with certain age ranges. Sls tracked a number of different cognitive abilities: verbal comprehension: passive vocab, spatial orientation: visualize and manipulate spatial configurations, numeric ability: work with numerical relationships inductive reasoning: understand novel concepts and planning. Cross sectional data: age-related differences, gradual decline of most factors starting at 25, numeric and verbal abilities appear to improve until mid-life. Longitudinal data: age related changes, collected as longitudinal data, different patterns emerge: everything stays roughly the same until about age 60. Using natural settings in research: approaches vary based on the degree of intervention during observation, naturalistic observations. Overt: the nature might be aware, but observing from a distance: participant observations. Researcher becomes part of the group being observed.
