Previous research has demonstrated that heightened ruminative disposition is characterized by an attentional bias to depressogenic information at 1,000-ms exposure durations. However, it is unknown whether this attentional bias reflects facilitated attentional engagement with depressogenic information, or impaired attentional disengagement from such information. The present study was designed to address this question. In keeping with recent theoretical proposals, our findings demonstrate that heightened ruminative disposition is associated only with impaired attentional disengagement from depressogenic information, and does not involve facilitated attentional engagement with such information. In addition to resolving this key issue, the present study provided converging support for the previous claim that rumination-linked attentional bias is specific to depressogenic information, and also lends weight to the contention that rumination-linked attentional bias may be evident only when controlled attentional processing is readily permitted by using stimulus exposure durations of 1,000 ms. We discuss the theoretical implications of these findings and highlight key issues for future research.
先前的研究表明，沉思倾向增强的特征是在 1000 毫秒的暴露持续时间内对致郁信息的注意力偏向。然而，目前尚不清楚这种注意力偏向是否反映了对致郁信息的注意力更容易参与，还是对这种信息的注意力难以脱离。本研究旨在解决这个问题。根据最近的理论建议，我们的研究结果表明，沉思倾向增强仅与对致郁信息的注意力难以脱离有关，而不涉及对这种信息的注意力更容易参与。除了解决这个关键问题外，本研究还为以前的观点提供了有力的支持，即与沉思相关的注意力偏向特定于致郁信息，同时也支持这样的观点，即只有在使用 1000 毫秒的刺激暴露持续时间允许进行受控注意力处理时，与沉思相关的注意力偏向才会明显。我们讨论了这些发现的理论意义，并强调了未来研究的关键问题。
