Ryan and Deci, 2000): most people play video games because they are inherently interesting and enjoyable rather than because they provide financial rewards or other external outcomes (Ryan et al., 2006 Przybylski et al., 2009, 2010). Video game playing is intrinsically motivating (cf. ![]() We propose that the striatal responses to repeated acquisition of rewards that are contingent on game related successes contribute to the motivational pull of video-game playing. Our findings demonstrate striatum to be selectively sensitive to self-acquired rewards, in contrast to frontal components of the reward circuit that process both self-acquired and passively received rewards. Self-ratings indicated losing to be more unpleasant during active than vicarious playing. Sensorimotor confounds related to joystick movements did not account for the results. In contrast, both wins and losses suppressed activations in the midbrain and striatum during active playing however, the striatal suppression, particularly in the anterior putamen, was more pronounced during loss than win events. Brain activation was stronger in the orbitomedial prefrontal cortex (omPFC) during winning than losing, both during active and vicarious playing. Wins and losses were paired with symmetrical monetary rewards and punishments during active and vicarious playing so that the external reward context remained identical during both conditions. Eleven healthy males both played a competitive first-person tank shooter game (active playing) and watched a pre-recorded gameplay video (vicarious playing) while their hemodynamic brain activation was measured with 3-tesla functional magnetic resonance imaging (fMRI). Here we show that striatal reward circuit responses elicited by successes (wins) and failures (losses) in a video game are stronger during active than vicarious gameplay. The extent to which active engagement influences dopaminergic brain reward circuit responses remains unsettled. ![]() ![]() Although the multimodal stimulation provided by modern audiovisual video games is pleasing by itself, the rewarding nature of video game playing depends critically also on the players' active engagement in the gameplay. ![]()
