| Summary: | Introduction: Having an identity as a ‘drinker’ has been linked to increased alcohol-related harm, self-reported consumption and self-reported intention to engage in risky drinking behavior. These effects have been observed when identities have been measured using explicit measures (e.g. via questionnaires) and implicitly (e.g. using Implicit Association Tests [IATs] adapted to measure identity). Little research has used actual behavioral measures to measure alcohol consumption in-the-moment, nor compared the effects of implicit and explicit identities directly.
Methods: Participants' (n = 40) implicit and explicit identities associated with being a drinker were measured. Attitudes towards one's own drinking were measured explicitly. Participants completed a Pouring Taste Preference Task [PTPT] involving the consumption and rating of non-alcoholic wine. This provided a behavioral measure of intention (pouring), a behavioral measure of consumption and a measure of the implementation of intention into behavior.
Results: Results showed an interactive effect of implicit and explicit identities on attitudes and behavior. Explicit identities predicted attitudes towards drinking, but not behavior. Neither identity predicted the amount poured. Implicit identities predicted the amount consumed. A greater proportion of wine poured was predicted by higher implicit identities when explicit identities were absent.
Conclusion: These results suggest that explicit identities may be associated more with those beliefs about drinking that one is aware of than behavioral intention. In addition, explicit identities may not predict behavioral enactment well. Implicit identity shows effects on actual behavior and not behavioral intention. Together this highlights the differential influence of reflective (explicit) and impulsive (implicit) identity in-the-moment behavior.
