The aim of the current study was to investigate if Openness – to – Experience and Neuroticism personality traits are associated with curiosity. This will help us to estimate whether knowledge expansion is dependent on a person’s personality and which trait is more willing to invest time on learning. The experiment consisted of two different sessions. To estimate curiosity, 40 subjects first performed a word-synonymy task, where Shannon’s (1948) entropy was estimated and the result of which lead to the measurement of uncertainty. Then in a second session, participants had the option to request for feedback between a few alternative options at a cost (time), and they were also required to estimate their satisfaction about the answer on a valence rating scale. Finally, participants were screened for personality traits. Neurotic individuals appeared to be more willing in investing time on feedback request, in contrast to open individuals.
