Even though it is diminishing in Europe, smoking is still a serious health problem. The craving of Nicotine is one of the hardest behaviours to tackle when a smoking cessation programme is implemented. Following on previous work [1], which aimed at evaluating the possibility of inducing smoking craving in smokers using a VR platform, the present study was devised to assess the role of craving in cognitive processing through event related potentials (ERP). From an initial sample of 89 university students (smokers and non-smokers), which was randomly exposed to VR smoking cues and VR non-smoking cue scenarios, a subsample of 13 smokers and non-smokers was drawn. This subsample (M = 23.08; SD = 4.39), which had previously been immersed in the VR smoking cues environment, was presented to a rapid (1 sec) serial of smoking and neutral images. Data on brain activity was recorded through an EEG during this task to further estimate ERPs. When compared to non-smokers, smokers showed higher frontal activation when watching smoking related images.
尽管在欧洲吸烟现象正在减少，但它仍然是一个严重的健康问题。在实施戒烟计划时，对尼古丁的渴望是最难克服的行为之一。继之前旨在评估使用虚拟现实（VR）平台诱发吸烟者吸烟渴望可能性的研究[1]之后，本研究旨在通过事件相关电位（ERP）评估渴望在认知加工中的作用。从89名大学生（吸烟者和非吸烟者）的初始样本中随机抽取13名吸烟者和非吸烟者作为子样本，该初始样本被随机暴露于VR吸烟线索和VR非吸烟线索场景中。这个子样本（M = 23.08；SD = 4.39）之前曾沉浸在VR吸烟线索环境中，他们被呈现一系列快速（1秒）的吸烟和中性图像。在这项任务中通过脑电图（EEG）记录大脑活动数据，以进一步估计ERP。与非吸烟者相比，吸烟者在观看吸烟相关图像时额叶激活程度更高。
