One hundred and seven healthy volunteers were administered Cloninger's Tridimensional Personality Questionnaire (TPQ), the Differential Attentional Processes Inventory (DAPI), Tellegen Absorption Scale (TAS), Stanford Hypnotic Susceptibility Scale, Form C (SHSS:C). Polymorphisms of catechol O-methyltransferase (COMT), an enzyme involved in dopamine metabolism, assessed. Highly hypnotizable subjects self-reported greater TPQ persistence, absorption, focused attentional abilities. Hierarchical multiple regression analyses found that COMT, TAS, DAPI scales explained 43.8% variance women 29% men. Membership was correctly discriminated for more extreme low (62.1%) highly (81.5%) groups. These results suggest persons have a effective frontolimbic system further involvement dopaminergic systems hypnotizability.
