The article addresses a particularly current and important topic in the condition that since ancient times, optimism has been correlated with the human psyche, primarily with emotions, and mood, positive emotions and humor are recognized as components of it. The research sample consisted of 70 people aged between 25-35 years. The following methods were applied in the research: Optimism level test according to K. Scheer and M. Carver (adapted by T.O. Gordeeva, Sychev and E.N. Osin) and Humor style questionnaire according to R. Martin. The obtained results highlight a link of interdependence between the variables included in the research. For female subjects, self-motivating humor shows a significant correlation with optimism, positive expectation and negative expectations. Also, aggressive humor shows a significant correlation with negative expectations and optimism. In male subjects, we highlight a positive correlation between affiliative humor and negative expectations. The conclusions highlight the role of optimism in the human experience as a positive aspect of strengthening social bonds and interpersonal relationships, thinking about the future and achieving goals, as well as a negative influence on unrealistic aspirations and hopes.
