This chapter discusses how emotions impact learning and processing of information in the brain. It describes the autonomic nervous system and how emotional states can influence physiological responses in the body. A key point is that the amygdala acts as a switch, determining whether incoming sensory information reaches the prefrontal cortex for higher-level cognitive processing, or is routed to the lower, more reactive parts of the brain. Stressors like boredom and frustration can put the amygdala into a hyper-metabolic state, diverting information away from the prefrontal cortex and inhibiting learning. The chapter explores strategies to promote positive emotional states that are optimal for learning.
