A flicker change blindness task employing eye tracking reveals an association with levels of craving not consumption

We investigated attentional biases with a flicker paradigm, examining the proportion of alcohol relative to neutral changes detected. Furthermore, we examined how measures of the participants initial orienting of attention and of their maintained attention relate to levels of alcohol consumption and subjective craving in social drinkers. The eye movements of 58 participants (24 male) were monitored whilst they completed a flicker-induced change blindness task using both simple stimuli and real world scenes, with both an alcohol and neutral change competing for detection. When examined in terms of consumption levels, we observed that heavier social drinkers detected a higher proportion of alcohol related changes in real world scenes only. However, we also observed that levels of craving wer…
