![]() We find that people who report that they are optimistic have a positive a priori bias on the likelihood of future reward, whose influence reduces with experience. Using modeling, we could then quantify the link between self-report trait optimism and decision or learning biases. We asked human subjects to fill in questionnaires about trait optimism, then to participate in a behavioral experiment where they needed to infer the likelihood of visual targets to be associated with a reward. However, choices in simple behavioral tasks can also be used to infer how optimistic people are in practice. In individuals, trait optimism is usually measured using self-report questionnaires. The optimism bias is regarded as one of the most prevalent and robust cognitive biases documented in psychology and behavioral economics. Contrary to findings in the literature related to unrealistic optimism and self-beliefs, it does not appear to influence the iterative learning process directly. its influence reduces with increasing experience. Critically, this positive belief behaves like a probabilistic prior, i.e. We find that trait optimism relates to an a priori belief about the likelihood of rewards, but not losses, in our task. Here, we use a novel Pavlovian conditioning task, embedded in a normative framework, to directly assess how trait optimism, as classically measured using self-report questionnaires, influences choices between visual targets, by learning about their association with reward progresses. However, optimistic beliefs can at times appear surprisingly resistant to evidence, suggesting that optimism might also influence how new information is selected and learned. In Bayesian statistical theory, a priori beliefs can be overcome by experience. doi:10.1002/pon.Optimists hold positive a priori beliefs about the future.

One study found that expressive writing focused on positive emotions was linked to decreased mental distress and improved mental well-being. Write down your positive emotions: Research has shown that something as simple as writing down positive thoughts can help improve your optimism. If you are trying to develop a more optimistic attitude, set aside a few minutes each day to jot down some of the things for which you are grateful. One study found that participants who were assigned to write in a gratitude journal showed increased optimism and resilience. Practice gratitude: Gratitude can be defined as an appreciation for what is important in life.This allows you to feel more appreciative of what you have now and less consumed with regrets and anxieties. If you are living fully in the moment, you are much less likely to ruminate over negative past experiences or worry about upcoming events. Become more mindful: Mindfulness is a focus on being engaged, attentive, and present in the here and now. It can be a useful technique to help you focus on what matters in the present and avoid worrying about future events and things that are outside of your control.
