Piaget, like Freud, defines development in terms of age and related stages. However, Piaget’s stages are related to cognitive development as opposed to sexual development and/or unconscious motives. Piaget identified cognitive tasks to be completed at each stage, the success of which will enable the changes and therefore the adjustments for the next stages. Freud emphasized that failure to resolve a stage could result in lifelong consequences (such as being overly controlling, smoking, talking too much, etc.).
