Attentional bias for negative information, i.e. difficulties in disengagement from negative stimuli, is considered to be one of the core mechanisms involved in the onset and maintenance of depression. However, current attention training procedures aimed at reducing this bias have shown limited success. In addition to the reliability and validity concerns generated by the use of dot-probe paradigm in these procedures, an important factor is the limited consideration of motivational influences in the use of attention training. Therefore, in the current study we examined whether goal stimuli, reinforced with music reward, can modulate attention for negative information in dysphoric individuals. Using a novel attention task which measures gaze disengagement from negative faces, we found that dysphoric individuals displayed greater difficulties in disengaging eye-gaze from negative and directing it towards standard neutral stimuli, as compared to non-dysphorics. However, when using reward-reinforced goal stimuli, dysphoric individuals were as quick as non-dysphorics in disengaging attention from negative stimuli in order to engage with goal-related stimuli. These results provide preliminary evidence for the modulating role of music-reinforced goals in the attention system of depressed individuals, and highlight how music-reinforced goals can be incorporated in current attention training procedures to improve outcomes.
注意对负面信息的偏向,即难以从负面刺激中解脱出来,被认为是抑郁发生和维持的核心机制之一。然而,目前旨在减少这种偏向的注意力训练程序显示出的效果有限。除了这些程序中使用点探测范式所产生的可靠性和有效性问题外,一个重要因素是在使用注意力训练时对动机影响的考虑有限。因此,在目前的研究中,我们研究了以音乐奖励强化的目标刺激是否可以调节抑郁个体对负面信息的注意力。使用一种新的注意力任务来测量从负面面孔中脱离目光的能力,我们发现与非抑郁个体相比,抑郁个体在从负面刺激中转移目光并将其引导至标准中性刺激时存在更大的困难。然而,当使用奖励强化的目标刺激时,抑郁个体在从负面刺激中转移注意力以参与与目标相关的刺激时,与非抑郁个体一样迅速。这些结果初步证明了音乐强化目标在抑郁个体的注意力系统中的调节作用,并强调了如何将音乐强化目标纳入当前的注意力训练程序以提高效果。
