Zoe has just received an A for her first psychology assignment. She put a lot of effort into that assignment and is proud of how much she is already learning. Before she even realizes it, Zoe has a big smile on her face. These good feelings, along with the positive feedback from her instructor, motivate her to do well in the class. So she spends about 20 minutes reviewing the requirements for the next assignment and scheduling blocks of time in the coming week to read her webtext. Later that night, a loud sound startles Zoe awake from her sleep. She immediately jumps out of bed, her heart pounding, and can feel the muscles in her legs and arms shake as she runs toward the kitchen. Her mother calls out, "Sorry Zoe! Everything's okay. I dropped the pan of lasagna as I was putting it away." Zoe sighs and takes a deep breath. By the time she helps her mother finish cleaning up the mess, she is no longer scared and can feel her body returning to normal. Discuss how Zoe's brain is contributing to her feelings of happiness and motivation after receiving a good grade and positive feedback on her psychology assignment. What are specific neurotransmitters that are likely involved? Place quotation marks around any exact working that is used from the webtext.
