dc.description.abstractResponse inhibition, one component of cognitive control, refers to the ability to inhibit automatic responses and has been found to be impaired in gambling disorder. Recent models of cognitive control distinguish between two mechanisms: reactive (ability to stop in response to a stop-stimulus) and proactive control (ability to anticipate and prepare for a stop). Previous studies have focused on reactive modes of control in gambling disorder. Thus, the primary aim of this study was to assess the mechanisms of response inhibition in individuals with gambling disorder (n=27) and community controls (n=21) using a variant of the traditional stop-signal task. Second, the relationship between trait impulsivity, and reactive and proactive control was examined. No group differences in reactive or proactive control were found. However, one domain of trait impulsivity (premeditation) was associated with worse proactive control in the gambling group. Implications for impulsivity-focused approaches to treatment and future directions are discussed.en_US
