Extraverts React Faster and More Intensely to Positive Cues, Study Finds
A new study using a dynamic measurement approach shows that people who score higher on extraversion react faster, with stronger emotional peaks and more predictable patterns, to positive images than to negative ones. The findings suggest that extraversion is linked not merely to feeling happier on average, but to heightened reward sensitivity that unfolds in real time. The research used a novel method to track how emotions rise and fall moment by moment, providing a more nuanced picture of how personality shapes moment-to-moment experience. The work was conducted by a team led by a psychology professor, who paired a dynamic task with standard personality assessments to examine how extraverts and introverts differ in processing positive versus aversive stimuli.
