The main aim of the present study was to analyze ORN and ORP components of a single outcome gambling task (without the complexity and confound of the error/correct aspect) in the context of several key factors/dimensions, viz., valence, amount, gender, impulsivity and behavioral measures. Since our study has used a “single-outcome” gambling task (SOG), a novel paradigm, it is primarily exploratory in nature. While findings related to valence (loss/gain) and amount (50/10) dimensions (including the morphology and topography of ORN and ORP) are possibly unique to the SOG paradigm, comparisons are also made with previous findings of “two-outcome” tasks in order to elicit paradigm-specific features in the outcome related ERP components.
