沉思会增加患抑郁症的风险，而注意力分散则有助于将注意力从负面经历中转移开，从而降低风险。许多人以心理意象的形式进行反刍，而以意象为基础的反刍与抑郁症状的严重程度的关系比以语言思维的形式进行反刍更大。然而，我们还不明白为什么基于意象的反刍可能会特别成问题，也不知道如何干预以减少基于意象的反刍。青少年（N= 145）先进行负性情绪诱导，然后以心理意象或言语思维的形式进行反刍或分心的实验诱导，同时收集情感、高频心率变异性和皮肤电导反应数据。反刍与相似的情感、高频心率变异性和皮肤电导反应相关，无论青少年是以心理意象还是言语思维的形式被诱导进行反刍。注意力分散导致了更大的情感改善和更大的高频心率变异性增加，但当青少年被诱导以心理意象的形式分散注意力时，与口头思维相比，皮肤电导反应相似。研究结果强调了在评估反刍和使用分心干预时，在临床环境中考虑心理意象的重要性。
Rumination is associated with increased risk for depression whereas distraction helps draw attention away from negative experiences, lowering risk. Many individuals who ruminate do so in the form of mental imagery and imagery-based rumination is more highly associated with depressive symptom severity than ruminating in the form of verbal thoughts. We do not yet understand why imagery-based rumination may be especially problematic nor how to intervene to reduce imagery-based rumination, however. Adolescents (N= 145) underwent a negative mood induction followed by experimental induction of rumination or distraction in the form of mental imagery or verbal thought while affective, high-frequency heart rate variability, and skin conductance response data were collected. Rumination was associated with similar affective, high-frequency heart rate variability, and skin conductance response regardless of whether adolescents were induced to ruminate in the form of mental imagery or verbal thought. Distraction led to greater affective improvement and greater increases in high-frequency heart rate variability, but similar skin conductance responses when adolescents were inducted to distract themselves in the form of mental imagery compared with verbal thought. Findings emphasize the importance of considering mental imagery in clinical contexts when assessing rumination and when intervening using distraction.
