Seattle Longitudinal Study

The Seattle Longitudinal Study is a research project that began in the 1950s to understand how intelligence and cognitive abilities change throughout aging. It involves tracking the performance of a diverse group of individuals over decades, examining aspects like problem-solving, reasoning, and memory. The study has revealed that some cognitive abilities can improve with age, while others may decline. Its findings contribute to our understanding of aging, helping to identify patterns related to mental function and informing approaches to enhance quality of life in later years.
