Implicit priming of conflicting motivational orientations in heavy drinkers

摘要

BackgroundApproach and avoidance motivation for alcohol are relatively independent, and they operate in both automatic (or implicit) and controlled processes. In this study, we adapted methods previously used in the appetite literature and implicitly primed an alcohol-related motivational orientation (approach or avoidance) in order to investigate its influence on the opposing motivational orientation, in a group of non-dependent heavy drinkers. MethodsParticipants (N?=?110) completed computerised measures of attentional bias and avoidance for alcohol cues (visual probe task) and behavioural approach and avoidance for alcohol cues (Stimulus–response Compatibility (SRC) task). Word primes were subliminally presented during each trial of these tasks. Participants were randomly allocated to groups that were exposed to alcohol-appetitive primes, alcohol-aversive primes, or neutral primes. ResultsContrary to hypotheses, word primes had no effect on responding during the visual probe or SRC tasks. Supplementary analyses revealed that participants showed attentional avoidance of alcohol cues combined with slower behavioural avoidance responses to alcohol cues. Attentional bias was positively correlated with scores on the Alcohol Use Disorders Identification Test. ConclusionsIn contrast to previous findings from the appetite domain, our findings suggest that automatic alcohol cognitions are unaffected by implicit priming of motivational orientations, although features of our novel methodology may account for these results.
