Development

How do minds and behavior change across the lifespan?

Development concerns both change and continuity across a life. New ways of moving, thinking, communicating, and relating emerge through interactions between people and their surroundings. Adolescence and adulthood bring further changes in opportunities, responsibilities, and goals; development does not end when childhood does.

Start with How Do We Develop Across the Lifespan? for a broad introduction to these questions and the evidence used to answer them. The area connects observations of children, experiments, cultural comparisons, interventions, and longitudinal studies. Throughout, ask whose developmental course a finding describes, what the study actually follows over time, and which alternative explanations remain.
