The key to life history theory is that there are limited resources available, and focusing on only a few life history characteristics is necessary. Examples of some major life history characteristics include: Age at first reproductive event; Reproductive lifespan and ageing; Number and size of offspring
Life-span psychology can be defined as the exploration of biological, cognitive, and psychosocial changes and constancies that occur throughout the course of life. [6] It has been presented as a theoretical perspective, proposing several fundamental, theoretical, and methodological principles about the nature of human development.
