Design Between subject. Setting Eye-tracking laboratory at the University of Liverpool. Participants Student social drinkers ( n = 64). Measurements An operant choice task in which participants chose between simultaneously presented alcohol and non-alcohol drink rewards, while attentional bias for alcohol and non-alcohol drink cues was inferred from eye movements. Participants then consumed 30 mL of an alcoholic beverage, which was either presented alone (no devaluation: n = 32) or had been adulterated to taste unpleasant (devaluation: n = 32). Choice and attentional bias for the alcohol and non-alcohol drink pictures were then measured again. Findings Alcohol devaluation reduced behavioural choice for alcohol ( F = 32.64, P < 0.001) and attentional bias for the alcohol pictures indexed by dwell time ( F = 22.68, P < 0.001), initial fixation ( F = 7.08, P = 0.01) and final fixation ( F = 22.44, P < 0.001). Mediation analysis revealed that attentional bias partially mediated the effect of devaluation on alcohol choice; however, the proportion of the variance accounted for by attentional bias is low to moderate (∼30%). Conclusions Among student social drinkers, attentional bias is only a partial mediator of alcohol choice following devaluation of alcohol. Value-based decision-making may be a more important determinant of drinking behaviour among student social drinkers than attentional bias. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
