Theoretical relations between anxiety and curiosity have been suggested, and analogies have been drawn between the state-trait formulation in anxiety theory and research and a similar formulation in curiosity. Individual differences in the potential for curiosity experiences suggest a trait (C-Trait) formulation; while individual differences in curiosity experiences themselves (C-State) suggest a state formulation. Three studies reporting psychometric aspects of the Melbourne Curiosity Inventory concern descriptive statistical characteristics of the C-Trait and C-State scales, and the validity of the state-trait distinction for curiosity research. It is concluded that the scales have acceptable levels of reliability and validity to justify their use as research instruments.
