Rumination is associated with Major Depressive Disorder (MDD). To better understand this association, researchers have begun to investigate the relationship between rumination and cognitive biases that are linked to MDD. To date, several studies have found that rumination is related to negatively biased memory, but it is not clear whether this relationship is independent of depressive symptoms. To address this question, the present study examined 97 healthy Caucasian women between the ages of 18 and 25. Participants performed an encoding task of self-referent adjectives, followed by a recognition task. The recognition task utilized a remember/know paradigm to separately examine recollection-based memory and familiarity-based memory. Trait rumination was assessed using the ruminative response scale (RRS). Results indicate that high trait rumination is associated with selective enhancement of recollection for negative words compared to neutral words and a trend toward selective enhancement for recollection for negative words compared to positive words. Trait rumination does not affect biases in overall recognition sensitivity or familiarity.
沉思与重度抑郁症（MDD）有关。为了更好地理解这种关联，研究人员已开始研究沉思与与MDD相关的认知偏差之间的关系。迄今为止，多项研究发现沉思与负性偏差记忆有关，但尚不清楚这种关系是否独立于抑郁症状。为了解决这个问题，本研究对97名年龄在18至25岁之间的健康白人女性进行了调查。参与者先进行了自我参照形容词的编码任务，随后进行了识别任务。识别任务采用记住/知道范式来分别检验基于回忆的记忆和基于熟悉度的记忆。使用沉思反应量表（RRS）评估特质性沉思。结果表明，与中性词相比，高特质性沉思与对负性词回忆的选择性增强有关，并且与阳性词相比，对负性词回忆的选择性增强有一个趋势。特质性沉思不会影响整体识别敏感性或熟悉度方面的偏差。
