Abstract:
Objective To explore the influence on each dimension of executive function of social drinkers with moderate dose of alcohol intake and different alcohol expectations.Methods 90 university students who were social drinkers allocated randomly by a lottery method to drinking group (n=31),control group (n=30) and placebo group (n=29).The Stroop task,1-Back task and local-global task were employed to measure executive function from three aspects respectively,namely the inhibition,updating and shifting process.Results Drinking group was compared with the Control group in the three dimensions of executive function:inhibition ((61.65 ± 26.31) ms,(42.48 ± 32.94) ms),updating ((557.23 ± 86.24) ms,(515.02 ± 70.24) ms),and shifting process ((718.85±246.03) ms,(553.95± 151.74) ms).The differences were statistically significant (P＜0.05 or P＜0.01).Placebo group was compared with the control group,in the three dimensions of executive function:inhibition ((39.25±29.35) ms,(42.48±32.94) ms),updating ((516.32±73.25) ms,(515.02±70.24) ms),and shifting process ((591.20± 193.07) ms,(553.95± 151.74) ms),all the differences had no statistically significance (P＞ 0.05).In the drinking group,positive expectation was negatively related to each dimension of executive function (-0.427,-0.330,-0.383).The inhibition and the shifting process appeared significant correlation(P＜0.05).Negative expectation was positively related to each dimension of executive function (0.251,0.323,0.377).The shifting process appeared significant correlation (P＜0.05).Regression analysis showed that positive expectation was significantly negative predictions of inhibition and shifting process.Conclusion Executive function of social drinkers is damaged after moderate alcohol intake,and there are differences between executive function damage of different alcohol expectancy drinkers.
