Age effects refer to the impact or influence that a person's age has on various aspects of their behavior, cognition, health, or development. Researchers studying age effects aim to understand how and why certain characteristics or abilities change or improve with age, and how these changes may differ among individuals or populations. Age effects can be studied in a wide range of disciplines, including psychology, sociology, gerontology, and medicine, and can provide valuable insights into the aging process and potential interventions to promote healthy aging.
