How is learning supported by emotions?
Joe Dispenza in his book Evolve your Brain explains:
“The release of different brain chemicals produces specific feelings, consequently, the end product of every experience is a feeling or an emotion. Feelings are chemical memories. When we remember an experience, we feel the exact same way we did at the time of the event”.
On this topic I can recommend a good movie based on a true story: “The Pursuit of Happyness” or “Das Streben nach Glück” (the german variant)
