To address shortcomings of purely reaction-time based attention bias modification (ABM) paradigms, a novel eye-tracking based ABM training (ET-ABM) was developed. This training targets the late disengagement from negative stimuli and the lack of attention for positive information, which are characteristics of depression. In the present study, 75 dysphoric students (BDI ≥ 9) were randomly assigned to either this positive training (PT), or a sham-training (ST) that did not train any valence-specific gaze pattern (positive and negative pictures had to be disengaged from and attended to equally often). Results showed that the PT induced a positive attentional bias (longer fixations of positive than negative pictures). Although the ST group showed an increase in positive attentional bias as well, this increase was not as strong as in the PT group. Compared to the ST, the PT specifically induced faster disengagement from negative pictures. No differential training effects were found on stress responses or state rumination. These results show that the ET-ABM successfully modifies attentional processes, specifically late disengagement from negative stimuli, in dysphoric students, and hence might be a promising alternative to existing ABM paradigms.
为解决基于单纯反应时间的注意力偏差修正(ABM)范式的缺点,开发了一种新颖的基于眼动追踪的ABM训练(ET-ABM)。这种训练针对的是从负面刺激中延迟脱离以及对积极信息缺乏关注的情况,而这正是抑郁症的特征。在本研究中,75名烦躁不安的学生(贝克抑郁量表≥9)被随机分配到这种积极训练(PT)组或假训练(ST)组,假训练组不训练任何与效价相关的注视模式(对正性和负性图片的脱离和关注频率必须相同)。结果表明,PT诱导了积极的注意力偏差(对正性图片的注视时间长于负性图片)。虽然ST组的积极注意力偏差也有所增加,但这种增加不如PT组明显。与ST组相比,PT组能更快速地从负性图片中脱离。在应激反应或状态反刍方面未发现训练效果差异。这些结果表明,ET-ABM成功地改变了烦躁不安学生的注意力过程,特别是从负面刺激中延迟脱离的情况,因此可能是现有ABM范式中一种有前景的替代方法。
