The aim of the present study was to develop a new approach-avoidance task in a virtual environment that could be used to assess the response to virtual alcohol-related situations by heavy social drinkers (HSDs) and light social drinkers (LSDs). Thirty-six male undergraduates (18 HSDs, 18 LSDs) responded to signals when they pulled or pushed a joystick after watching scenes of alcohol- or nonalcohol-related situations in a virtual environment. The HSD group spent more time on moving away from alcohol-related situations than nonalcohol-related situations. We found that the HSD group had difficulty in avoiding alcohol-related situations in the virtual environment. The Virtual Approach-Avoidance Task might more accurately measure the levels of social drinkers' craving to drink as it provides realistic situations and allows individuals to be immersed in virtual environments.
本研究的目的是在虚拟环境中开发一种新的趋避任务，该任务可用于评估重度社交饮酒者（HSDs）和轻度社交饮酒者（LSDs）对与酒精相关的虚拟情境的反应。36名男性本科生（18名HSDs，18名LSDs）在虚拟环境中观看与酒精或非酒精相关的情境场景后，拉动或推动操纵杆时对信号做出反应。HSD组在远离与酒精相关的情境上花费的时间比远离非酒精相关的情境更多。我们发现HSD组在虚拟环境中难以避免与酒精相关的情境。虚拟趋避任务可能更准确地测量社交饮酒者的饮酒渴望程度，因为它提供了现实情境，并允许个体沉浸在虚拟环境中。
