Music to my ears, goal for my eyes? Music reward modulates gaze disengagement from negative stimuli in dysphoria.
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.
