Binge drinking is a common occurrence among younger people, especially univer

2、sity students酗酒指在禁欲后短時間里消費大量的酒精。酗酒的通常是年輕人，特別是大學生。定義、對象2、 The effects of alcohol on the central nervous system (CNS) have been extensively studied, and the neurocognitive, neuroanatomical and neurofunctional consequences of chronic alcohol abuse in alcohol-dependent adults have been documented (Oscar

More specifically, we wanted to examine whether there was any difference in cerebral reactivity between students with binge drinking habits and paired controls when they were confronted

7、 by alcohol-related compared to nonalcohol- related (control) cues.當前研究的目的在于去調查相比成人，短期的酒精暴露歷史、酗酒的學生和沒有診斷出AUD的人，是否展現出對任何酒精線索加工調節。更特別是，我們想調查對于非酒精-酒精相關線索對于酗酒的學生和配對控制組相比的大腦反應是否存在差異。6、Our main hypothesis was that binge drinkers (as compared to controls) will display an enhanced attentional processing of

11、損傷，過去和當前沒有藥物使用（酒精以外），沒有酒精成癮家族史，在上大學學習前酒精低消費和沒有酗酒習慣而且一直維持相同的模式到現在。為什么都有這些刷選標準？All participants were assessed for several psychological measures: State and Trait Anxiety (STAI A and B, Spielberger et al., 1983), depression (BDI, Beck and Steer, 1987) and alexithymia (TAS 20, Bagby et al., 1994).所有的被試要

According to their alcohol consumption characteristics while at university, students were divided into two groups, each of 18 parti

P100 amplitudes elicited by alcohol-related pictures were significantly larger than those elicited by neutral pictures in individuals with binge drinking habits, whereas there were no significant differences in the P100 amplitudes of controls with the different stimuli. 酗酒者和控制組的差異涉及到P100成分。酗酒者對酒精相關圖片相比中性圖片誘發更大的P100。而控制組沒有發現這個現象。（二） It is important to note that, even though such an increase in the P100 component was not observed in the control group, the results showed that, at a behavioural l
