What Trauma Is and Why It Matters

This lesson defines trauma in psychological terms and explains why it matters for mental health, relationships, learning, and physical wellbeing. Students will learn the difference between a traumatic event and a trauma response, why people can react very differently to similar experiences, and how trauma can affect attention, memory, emotion, and behavior. The lesson also introduces core trauma-informed principles that will be used throughout the course, while leaving treatment, recovery planning, and intervention strategies for later lessons.
