Long Beach Longitudinal Study
The Long Beach Longitudinal Study (LBLS) of cognition and aging seeks to study change and the predictors of change in cognitive processes across the adult life span. The LBLS approach to cognitive change and aging involves:
- evaluating individual differences in performance on cognitive measures
- relating sociodemographic phenomena (e.g. birth cohort, gender) to cognitive performance
- understanding how individual charateristics (e.g. personality, physical and mental health, affect) influence cognitive abilities.
- Start Year
