Abstract
<b>Aim</b>: To apply a new paradigm using transient changes to visual scenes to explore information processing biases relating to `social' levels of alcohol and cannabis use. <b>Participants</b>: Male and female student volunteers (n = 200) not self-reporting substance-related problems. <b>Setting</b>: Quiet testing areas throughout the university campus. <b>Design</b>: A flicker paradigm, for inducing change blindness with lighter and heavier social users of alcohol (experiment 1, n= 100) and social users and non-users of cannabis (experiment 2, n= 100), explored the associations between habitual level of use and the latency to detection of a single substance-related or neutral change made to a scene of grouped substance-related and neutral objects. <b>Measurements</b>: Alcohol use was measured as the number of units of the heaviest drinking day from the previous week; cannabis use as the number of months of use in previous 12. Change-detection latency comparisons were used to evaluate processing biases. <b>Findings</b>: In both experiments, (i) heavier social users detected substance-related changes quicker than lighter and non-users; (ii) lighter and non-users detected substance-neutral changes quicker than heavier users; (iii) heavier social users detected substance-related quicker than substance-neutral changes; and (iv) lighter and non-users detected substance-neutral changes quicker than substance-related changes. <b>Conclusions</b>: Alcohol and cannabis processing biases are found at levels of social use, have the potential to influence future consumption and for this reason merit further research.
