Aims Previous research has shown that consistently not responding to alcohol‐related stimuli in a go/no‐go training procedure reduces drinking behaviour. This study aimed to examine further the mechanisms underlying this go/no‐go training effect. Design, setting and participants Fifty‐seven heavy drinkers were assigned randomly to two training conditions: in the beer/no‐go condition, alcohol‐related stimuli were always paired with a stopping response, while in the beer/go condition participants always responded to alcohol‐related stimuli. Participants were tested individually in a laboratory at Maastricht University. Measurements Weekly alcohol intake, implicit attitudes towards beer, approach–avoidance action tendencies towards beer and response inhibition were measured before and after the training. Findings Results showed a significant reduction in both implicit attitudes ( P = 0.03) and alcohol intake ( P = 0.02) in the beer/no‐go condition, but not in the beer/go condition. There were no significant training effects on action tendencies or response inhibition. Conclusions Repeatedly stopping pre‐potent responses towards alcohol‐related stimuli reduces excessive alcohol use via a devaluation of alcohol‐related stimuli rather than via increased inhibitory control over alcohol‐related responses.
