令人满意的人际互动包括理解他人的面部表情。酗酒者通常有严重的人际关系困难，这可能与对面部表情的糟糕和扭曲的感知有关。在最近的灵长类动物研究中，负责检测注意方向的神经元的发现突显了注意方向的重要性。对人类的研究表明，表情知觉受到注意方向的调节(无论表情是朝向还是远离观察者)。这里。首次对酗酒者和对照组的注意方向与表情知觉(愤怒、悲伤、快乐和厌恶)之间的关系进行了研究。我们使用描绘不同情绪的动画面部刺激来衡量识别的准确性和感知敏感度。我们的研究表明，酗酒者在识别表情时比对照组的受试者犯了更多的错误，并倾向于错误地将针对他们的悲伤表情误认为是敌意的(愤怒/厌恶)。当被要求选择他们开始看到这个表情的时间点时，酗酒者。尤其是女性酗酒者，选择了更高的表达强度。这项研究强调了在研究表情感知时调查注意方向的调节作用的重要性，并提供了酗酒者不适当的社会反应可能如何被触发的指示，(C)2002 Elsevier Science爱尔兰有限公司。保留所有权利。
Satisfactory interpersonal interaction involves understanding others' facial expressions. Alcoholic individuals often have severe interpersonal difficulties that may relate to poor and distorted perception of facial expressions. The importance of attention direction has been highlighted by the finding, in recent primate studies, of neurons responsible for the detection of attention direction. Studies on humans suggest that expression perception is modulated by attention direction (whether the expression is directed towards or away from the observer). Here. for the first time, the relationship between attention direction and perception of expression (anger, sadness, happiness and disgust) in alcoholic and control subjects is investigated. We used animated facial stimuli depicting different emotions to give measures of recognition accuracy and of perceptual sensitivity. Our study demonstrated that alcoholics made more errors than control subjects in recognising expressions generally and had a tendency to mis-label sad expressions directed towards them as being hostile (angry/disgusted). When asked to select the point when they started to see the expression, alcoholics. especially female alcoholics, chose higher expression intensities. This study highlights the importance of investigating the modulating effects of attention direction when studying the perception of expressions and provides an indication of how alcoholics' inappropriate social reactions may be triggered, (C) 2002 Elsevier Science Ireland Ltd.
