Optimism refers to peoples’ general tendency to anticipate good outcomes in areas that are important to them. Numerous studies have shown that optimism is significantly correlated with improved physical and mental health. Optimism can come to an overly optimistic degree, called optimism bias. People generally expect better outcomes and fewer negative events to happen for themselves in the future compared to the average person. There are two sides to this: being optimistically biased might lead to risky behavior, but it might also ease people's worries about the future. To have a consistently negative view is suggested to correlate with depressive symptoms and worsened health. The aim of this thesis is to investigate the neural correlates and functional markers of optimism and optimism bias. Optimism is suggested to correlate with gray-matter volume in the thalamus, orbitofrontal cortex (OFC), and bilateral putamen. The inferior frontal gyrus (IFG) and the rostral anterior cingulate cortex (rACC) have a crucial role in dismissing undesirable information and self referential processing. Research regarding this issue might be beneficial for further understanding of the connection between optimism and well-being.
