Three Major Issues of Developmental Psychology
- Nature vs. Nurture - This issue revolves around the relative contributions of both genetic inheritance (nature) and experience (nurture) on our development.
- Continuity vs. Stages - There are different, opposing theories on whether or not our development is a gradual, continuous process, or a sequence of separate stages.
- Stability vs. Change - This dilemma regards the persistence or evolution of our personality traits - do they persist or do they change?
