Final answer:
Children's development is best described as organized and hierarchical, with development occurring in stages that are unique and at specific times or ages.
Step-by-step explanation:
Children's development occurs in a organized and hierarchical manner. This concept is evidenced by the theorists who view development as discontinuous, believing that development happens in unique stages that occur at specific times or ages, such as the acquisition of object permanence in infants. Contrasting with continuous development, which views development as a cumulative process of gradually improving on existing skills, such as the physical growth of a child adding inches to height year by year. Furthermore, in the broader context of organismal development, mammals exhibit a determinate form of development, reaching an endpoint at the adult form. Conversely, plants and fungi may display indeterminate development, where no endpoint exists, and parts of the organism retain embryonic characteristics, allowing perpetual growth.
