The continuous development theory sees our development as a cumulative process with gradual changes, for example: children become more skilfull in talking as they get taller, while discontinous development theory sees our development as taking place in stages, for example: the changes have a abrupt sucession, the children become more skilfull in a specific stage or age. Is possible to see they both a partially correct, bacause the development is a complex process that have various moments, they can happen in abrupt circumstances or in really gradual process. In a bird we see the gradual development for learning, we can see a more abrupt change in other animals that is ralated more to the age than the grown in time and force of the organism.
