The effect of rumination on recall of emotional words: comparison of dysphoric individuals with and without a history of nonsuicidal self-injury

ABSTRACT

Prior research and theory has suggested that rumination plays a role in nonsuicidal self-injury (NSSI), and rumination increases recall of negative autobiographical information in dysphoric individuals. Across two studies, we investigated whether rumination (versus distraction) differentially influences the recall of emotional words among dysphoric persons with and without a history of NSSI. Participants encoded unpleasant, neutral, and pleasant words and then were randomly assigned to either focus on the meaning and consequences of their emotions (i.e. rumination) or unrelated thoughts (i.e. distraction) before they were asked to recall encoded words. Across the two studies, we did not find a significant effect of rumination on memory for emotional words among dysphoric people with (Studies 1 and 2) or without a history of NSSI (Study 1). We did find that people were more likely to remember neutral words as opposed to unpleasant or pleasant words across studies, regardless of rumination condition. Together, results from these two well-powered studies provide fairly compelling evidence that rumination after encoding has little to no effect on recall for emotional words in people elevated on symptoms of depression or with NSSI history. These findings can be used to refine theories of rumination and NSSI.     

Mood-congruent attention and memory bias in dysphoria: Exploring the coherence among information-processing biases

Recent studies indicate that depression is characterized by mood-congruent attention bias at later stages of information-processing. Moreover, depression has been associated with enhanced recall of negative information. The present study tested the coherence between attention and memory bias in dysphoria. Stable dysphoric (n = 41) and non-dysphoric (n = 41) undergraduates first performed a spatial cueing task that included negative, positive, and neutral words. Words were presented for 250 ms under conditions that allowed or prevented elaborate processing. Memory for the words presented in the cueing task was tested using incidental free recall. Dysphoric individuals exhibited an attention bias for negative words in the condition that allowed elaborate processing, with the attention bias for negative words predicting free recall of negative words. Results demonstrate the coherence of attention and memory bias in dysphoric individuals and provide suggestions on the influence of attention bias on further processing of negative material.     

Why Me? The Persistence of Negative Appraisals Over the Course of Illness1

This paper examines the relationship of illness appraisals and causal attributions to later psychological adjustment among individuals coping with a chronic illness. Data on threat and challenge appraisals, causal attributions, and depression were collected twice over an 18-month period from patients with recently diagnosed rheumatoid arthritis (RA). Appraisals and attributions were differentially related to psychological adjustment. Challenge appraisals were stable over time but were unrelated to depression. Internal, stable, global attributions about the diagnosis were associated with greater depression at follow-up for subjects who were initially high on the depression measure but were related to lowered depression for individuals with initially low depression. An interaction between initial threat appraisals and depression was also found for depression 18 months later. For individuals with low depression scores initially, threat appraisals were related to greater depression later; when initial depression was high, threat appraisals were unrelated to later depression. In addition, initial threat appraisals mediated the relationship between initial level of depression and rumination (continuing to ask, “Why me?”) 18 months later. These findings are discussed in terms of the failure to achieve some resolution about the place of the illness in one's life and of theories of dysphoric rumination that suggest that negative self-focus contributes to a continuing depressed mood.     

Why ruminators are poor problem solvers: clues from the phenomenology of dysphoric rumination

The phenomenology of dysphoric rumination and its consequences for problem solving were explored in 3 studies. In Study 1, self-focused rumination, compared with distraction, led dysphoric participants to rate their own biggest problems as severe and unsolvable and to report a reduced likelihood of actually implementing their solutions. Clues into the mechanisms behind these findings were explored in Study 2. The results showed that dysphoric ruminative thought is characterized by a focus on personal problems combined with a negative tone, self-criticism, and self-blame for problems as well as reduced self-confidence, optimism, and perceived control. Finally, Study 3 revealed a direct relationship between the negatively biased content of ruminative thoughts and reduced willingness to solve one's problems. Implications of these findings for the consequences of self-focused rumination are discussed.     

Extending self-regulated learning to include self-regulated emotion strategies

Emotions and their regulation were examined in favorite and least favorite academic courses. Building on prior research, three forms of regulation (suppression, reappraisal, and rumination) were examined. Reappraisal was positively related to positive emotions across contexts and negatively related to negative emotions in favorite courses. Rumination was positively related with negative emotions in both contexts and negatively related to positive emotions in least favorite courses. Surprisingly, suppression was negatively related to activated positive emotions (excitement) in favorite courses, but positively related to positive deactivated emotions (relaxation) in least favorite courses. Person-centered analyses using latent classes revealed that in favorite courses, the use of rumination was critical in differentiating regulatory profiles. In contrast, reappraisal distinguished among the regulatory profiles in least favorite courses. Results suggest that self-regulated emotion strategies are differentially employed based on course preference and highlight the potential utility in considering self-regulated emotion strategies as part of self-regulated learning.     

沉思和分心对负情绪和自传体记忆的影响

探讨在诱发了抑郁、焦虑、悲伤等负性情绪后,沉思和分心对正常成人的情绪主观报告、生理变化和自传体记忆的作用。64名被试被随机分为两组,用故事和电影短片分别诱发了负性和中性（控制组）两种情绪状态。然后进行随机分组,分别进行分心和沉思的反应任务。测量四组被试的情绪主观报告、生理变化以及多种形式和性质的自传体记忆。结果表明：（1）沉思和分心对这些负情绪的调节作用不显著;（2）沉思引起更多的负性记忆,正性复合指数更小,自传体记忆的具体性更弱。结论：沉思导致更多负性记忆,维持了概括性记忆,更有可能加重已经激活的负情绪     

Everyday emotion word and personal pronoun use reflects dyadic adjustment among couples coping with breast cancer

Dyadic adjustment is integral for couples facing breast cancer; therefore, it is important to identify its everyday indicators. A total of 52 couples coping with breast cancer wore the Electronically Activated Recorder (EAR) for one weekend and completed the Dyadic Adjustment Scale to investigate how dyadic adjustment manifests in noncancer‐related word use. Multilevel models revealed that partners', rather than one's own, positive emotion words positively related to dyadic adjustment. Conversely, spouses' negative emotion words and patients' anger words were negatively related to dyadic adjustment. Furthermore, focus on spouses rather than patients (spouses “I” and patients “you”) positively related to dyadic adjustment. Results revealed that dyadic adjustment can be reflected in couples' everyday word use, serving as an objective indicator of marital quality.     

Predicting Cognitive and Social Consequences of Emotional Episodes: The Contribution of Emotional Intensity, the Five Factor Model, and Alexithymia

Emotional events are followed by recurrent thoughts (rumination) and talking about the event (social sharing of emotion). Factors that can account for variations in these consequences were examined (emotional intensity, the Five Factor Model, and two factors of alexithymia). In two samples, participants reported the most negative emotional event of recent months and in one sample also reported the most positive one. Results indicated that emotional intensity predicted social sharing and rumination, while neuroticism was positively related to intrusive thoughts about negative events and extraversion to rumination and social sharing about positive events. Difficulty describing feelings was negatively related to social sharing for negative events and reduced fantasy to rumination for positive events.     

Rumination and overgeneral autobiographical memory

Two studies investigated the effects of rumination on the retrieval of autobiographical memories in high-depressed and low-depressed individuals. Experiment 1 administered either a rumination or distraction task prior to a cued autobiographical memory task. High-depressed participants recalled more overgeneral memories following rumination relative to distraction, whereas experimental inductions did not influence low-depressed participants. Experiment 2 administered either a positive or negative rumination task prior to a cued autobiographical memory task. Negatively valenced rumination led high-depressed participants to recall more overgeneral memories than positively valenced rumination; this effect was not observed in low-depressed participants. These findings accord with the proposal that rumination is a mediating mechanism in the retrieval of overgeneral memories, and extends this proposal by indicating that negatively valenced ruminative content is particularly instrumental in inducing overgeneral retrieval.     

Responses to Positive Affect in Daily Life: Positive Rumination and Dampening Moderate the Association Between Daily Events and Depressive Symptoms

Depressive rumination has been strongly linked to the development and maintenance of depression; however, less attention has been paid to ruminative processes in response to positive affect, and fewer have examined these processes in daily life. The current study sought to address these gaps by exploring depressive rumination and two forms of responses to positive affect, dampening and positive rumination, under ecologically valid conditions using daily diary methodology. One hundred fifty-seven young adults completed 14-day end-of-day diaries assessing positive affect and depressive symptoms in relation to depressive rumination, responses to positive affect, and daily positive and negative events. Daily depressive rumination predicted stronger associations between negative events and daily depressive symptoms. Higher daily dampening was associated with higher daily depressive symptoms and decreased positive affect and predicted lower associations between daily positive events and improvements in mood (including reduced daily positive affect and increased daily depressive symptoms). Higher daily positive rumination was negatively associated with daily depressive symptoms and interacted with daily positive events such that positive rumination had a greater impact on depressed mood on days when positive experiences were low. Results indicate that both depressive rumination and responses to positive affect play a role in influencing daily mood and depressive symptoms.     

Attention and the processing of emotional words: Dissociating effects of arousal

There is debate as to whether emotionally charged words receive preferential attentional processing in normal individuals. Using a digit-parity task, Harris and Pashler (2004) found that threat-related words captured attention on only the first trial, suggesting no attention capture for emotional words aside from an initial surprise reaction. We examined whether sexually explicit words would be more effective at capturing attention in a similar task. Our results with threat words replicated those of Harris and Pashler in that threat words did not lead to an increase in reaction time (RT) on the parity task, relative to emotionally neutral words. However, sexual words led to a marked increase in RTs for over 100 trials. Words’ arousal ratings, but not their valence ratings, predicted the amount of interference. Parity RTs for individual words were also related to memory for the word on a surprise memory test. Sexually explicit words may have more potential to capture attention than do threat-related words. The words presented here as distractors in the digit-parity task, along with their corresponding valence ratings, arousal ratings, and digit-parity RTs, can be downloaded from www.psychonomic.org/archive.     

Gaze-fixation and pupil dilation in the processing of emotional faces: The role of rumination

Sustained attentional processing of negative information plays a significant role in the development and maintenance of depression. The present study examines the relationships between rumination, a relevant factor in information processing in depression, and the attentional mechanisms activated in individuals with different levels of depression severity when attending to emotional information (i.e., sad, angry and happy faces). Behavioural and physiological indicators of sustained processing were assessed in 126 participants (39 dysphoric and 87 non-dysphoric) using eye-tracking technology. Pupil dilation and total time attending to negative faces were correlated with a global ruminative style in the total sample once depression severity was controlled. Furthermore, in dysphoric participants the brooding component of rumination was specifically associated with the total time attending to sad faces. Finally, bootstrapping analyses showed that the relationships between global rumination and pupil diameter to emotional faces were accounted by total time attending to emotional faces, specifically for participants reporting lower levels of depression severity. The results support the idea that sustained processing of negative information is associated with a higher ruminative style and indicate differential associations between these factors at different levels of depressive symptomatology.     

Does worry affect adjustment to bereavement? A longitudinal investigation

Background and objectives: Repetitive thought is a trans-diagnostic risk-factor for development of psychopathology. Research on repetitive thought in bereaved individuals has focused primarily on clarifying the role of rumination, repetitive thinking about past negative events and/or negative emotions. While detrimental effects of rumination have been demonstrated following bereavement, surprisingly few studies have aimed to clarify the role of worry, repetitive thinking about potential future negative events, in adjustment to loss. This study sought to fill this gap in knowledge. Methods/Design: One hundred eighty-three bereaved individuals (85.3% women) filled out questionnaires on sociodemographic and loss-related characteristics, worry, and symptom measures of depression, anxiety, and prolonged grief. After six months, 155 participants completed worry and symptom measures again. Using multiple regression analyses, concurrent and longitudinal associations between loss-related variables, worry, and symptoms of psychopathology were examined. Results: Main results were that worry was strongly positively associated with symptoms of anxiety, depression and prolonged grief concurrently and also predicted higher levels of anxiety, depression and prolonged grief longitudinally. Conclusions: Findings suggest that worry influences adjustment to bereavement negatively and may be a potential target in grief therapy, especially when aiming to reduce anxiety.     

Perfectionism, anger, and anger rumination

Anger and anger rumination are considered to be detrimental to both physical and psychological well being. Furthermore, perfectionism, as a personality construct, seems to be related to various types of maladjustment. Whereas perfectionism has been characterized as being positive when an individual derives pleasure from striving for excellence yet recognizes and accepts individual limitations, it is deemed negative when the individual has unrealistic expectations and is never satisfied with his or her performance. The present study examined whether positive and negative perfectionism was associated with anger and anger rumination. The Farsi version of the Positive and Negative Perfectionism Scale and the Farsi version of the Anger Rumination Scale, as well as Spielberger's State-Trait Anger Scale were completed by 384 Iranian students. Results showed that anger and anger rumination were, as expected, associated negatively with positive perfectionism and associated positively with negative perfectionism. Positive perfectionism enables individuals to strive for success in a flexible manner and, thus, to experience satisfaction and pleasure rather than dissatisfaction, frustration, and anger. Conversely, negative perfectionism makes individuals vulnerable to emotional distress such as predisposition to experience anger and anger rumination through setting high standards for performance, overgeneralization of perceived failures, negative self-evaluation, self-blame, and measuring self-worth in terms of unachievable goals of accomplishment and productivity. Hence, perfectionism may be regarded as having both adaptive and maladaptive aspects with regard to health.     

Emotional Awareness in Daily Life: Exploring Its Potential Role in Repetitive Thinking and Healthy Coping

Cross-sectional research has found that emotional awareness, which is composed of one’s emotional clarity and attention to emotions, is associated with psychopathology, emotion regulation, and coping. Not surprisingly then, emotional awareness is often a target of cognitive and behavioral therapies. However, little is known about what emotional awareness is related to in daily life, which would inform how and for whom emotional awareness training should be conducted in therapeutic settings. The goal of the current studies was to examine associations among facets of emotional awareness and repetitive thinking (i.e., rumination, worry, and reflection), emotion regulation, and coping in daily life. We conducted two 7-day daily diary studies (n = 172 in Study 1, n = 211 in Study 2) measuring daily experiences of repetitive negative thinking, emotion regulation efforts, and coping. Multilevel models showed that trait levels of emotional clarity were negatively associated, at the between-person level, with daily levels of repetitive negative thinking and positively associated with active coping. Additionally, daily levels of emotional clarity were associated, at the within-person level, with worrying and active coping, whereas daily levels of attention to emotions were associated, at the within-person level, with reflection. Theoretical and clinical implications for emotional awareness, particularly emotional clarity, are discussed.     

反刍思维与注意脱离损坏的关系及其神经机制

反刍思维是一种重复性的消极思维, 会让个体将注意集中在消极痛苦的事情上。研究表明, 反刍思维和注意脱离损坏虽然是相互独立的概念, 但是二者却存在着密切的联系, 具体表现在注意脱离损坏会预测个体的反刍思维以及反刍思维有关的注意脱损坏可能是受到意识控制的。同时, 反刍思维的类型和自我相关性在反刍思维和注意脱离损坏关系中的作用依然需要进一步探究。另外, 注意脱离有关的训练明显地改善了个体的反刍思维。并且, 杏仁核的过度激活, 前扣带回(anterior cingulate cortex, ACC)对自我相关消极信息的调节异常, 右背外侧前额叶(dorsal lateral prefrontal cortex, DLPFC)的活动异常以及与注意有关的脑神经网络的结构和功能的异常可能是反刍思维和注意脱离损坏相互影响的原因。     

Mood-congruent free recall bias in anxious individuals is not a consequence of response bias

The status of mood-congruent free recall bias in anxious individuals was evaluated following incidental encoding of target words. Individuals with high and low levels of trait anxiety completed a modified Stroop task, which revealed an attentional bias for threat-related stimuli in anxious individuals. This group was significantly slower in naming the colour in which threat-related words were displayed compared to neutral words. In a subsequent free recall test for the words used in the modified Stroop task, anxious individuals recalled more threat-related words compared to low-anxious people. This difference was significant even when controlling for the false recall of items that had not been presented during study. These results support the view put forward by Russo, Fox, Bellinger, and Nguyen-Van-Tam (2001) that mood-congruent free recall bias in anxious individuals can be observed if the target material is encoded at a relatively shallow level. Moreover, contrary to Dowens and Calvo (2003), the current results show that the memory advantage for threat-related information in anxious individuals is not a consequence of response bias.
