Themes and Methods in Developmental Psychology

What this topic is about

The review introduces developmental psychology as the study of changes across the lifespan. It raises questions about continuity and change and describes longitudinal and cross-sectional research as ways to study development over time. The example contrasts following the same group over time with comparing separate age groups, while noting cost and participant dropout.

Key ideas

• Development includes physical, cognitive, and social-emotional change.
• The video asks whether traits remain stable or change as people grow older.
• Longitudinal research follows the same participants over time and can be costly or affected by dropout.
• Cross-sectional research compares age groups at one point in time.
• The review uses research methods to frame later examples of developmental change.
