Implicit Association Test with Alcohol Related Words and Pictures in Alcohol Dependence Patients

Objectives：The Implicit Association Test (IAT) is a paradigm designed to assess individual difference in implicit cognition. This study investigated the difference of IAT effect of alcohol related pictures and words in alcohol dependent patients, heavy drinkers and control subjects. Methods：23 alcohol dependence patients, 23 heavy drinkers and 22 controls were included. All subjects per-formed two IAT, one of which was composed of alcohol related pictures and the other was made of words. Results：Repeated measurement ANOVA showed significant main effect of ‘Type of stimuli’ [F(1,65)=29.38, p<0.001], and IAT effect was more prominent by words than pictures. But there was no significant interaction of ‘Type of stimuli’ and ‘Group’ [F(1,65)=1.466, p= 0.238]. In between group analysis, there was the significant main effect of ‘Gorup’ [F(2,65)=4.007, p=0.023], and control group had significantly negative implicit cognition to alcohol than heavy drinker group. Conclusion：IAT effect was marked in alcohol related word than picture. But IAT effect pattern of each group was not changed by stimulus. Overall alcohol related word and picture show difference in IAT effect power but both alcohol related picture and word IAT was useful for estimate alcohol related implicit cognition.
