This document discusses the neuroscience of hazard awareness and the power of positive emotions. It explains that the threat response system in the brain is faster acting, stronger and longer lasting than the reward response system. Positive emotions broaden thinking and build personal resources. Research shows that positive people are healthier, more successful, caring and resilient. They perform better at work and keep their jobs longer. The document also covers neuroscience principles of learning like attention, generation effects, spacing effects, and using error detection to improve plasticity in the brain.
