情绪障碍及其干预:心理表象的视角

心理表象在多种情绪障碍中均表现出病理性特点。研究者基于心理表象主要对创伤后应激障碍、抑郁心境、双相障碍情绪和社交焦虑进行了心理病理学解释,尤其关注闪回和过度概化记忆等两种典型症状,并且重视心理表象在情绪症状维持中的作用。概括而言,研究者强调记忆形成与提取过程的异常、认知与行为的保护性策略的负强化、对事件及自我的认知偏差等三类因素对情绪障碍的致病作用。目前,针对或运用心理表象的干预与训练方法包括减少消极表象、改变消极表象内容、提高积极表象能力、提高记忆的具体性等四类。未来应注重侵入性表象的功能分析以及相关的心理病理学模型研究,并拓展干预与训练研究。     

The differential contributions of visual imagery constructs on autobiographical thinking

There is a growing theoretical and empirical consensus on the central role of visual imagery in autobiographical memory. However, findings from studies that explore how individual differences in visual imagery are reflected on autobiographical thinking do not present a coherent story. One reason for the mixed findings was suggested to be the treatment of visual imagery as an undifferentiated construct while evidence shows that there is more than one type of visual imagery. The present study investigates the relative contributions of different imagery constructs; namely, object and spatial imagery, on autobiographical memory processes. Additionally, it explores whether a similar relation extends to imagining the future. The results indicate that while object imagery was significantly correlated with several phenomenological characteristics, such as the level of sensory and perceptual details for past events – but not for future events – spatial imagery predicted the level of episodic specificity for both past and future events. We interpret these findings as object imagery being recruited in tasks of autobiographical memory that employ reflective processes while spatial imagery is engaged during direct retrieval of event details. Implications for the role of visual imagery in autobiographical thinking processes are discussed.     

Incorporating Imagery Into Thought Records: Increasing Engagement in Balanced Thoughts

Thought records are one of the most effective CBT interventions. However, clients can find them overly intellectual. While clients may logically understand that their balanced thought is accurate, they may not be emotionally convinced, thus reducing the thought record’s effectiveness. In the present paper we describe how imagery can be used throughout the thought record process to enhance clients’ emotional engagement. We describe how imagery can be used to identify negative automatic thoughts, to increase the believability of evidence against negative automatic thoughts, and to increase emotional engagement with balanced thoughts.     

Imagery and verbal thought during rumination and distraction: Does imagery amplify affective response?

Rumination has long been considered a verbal thought process, though emerging evidence suggests that some individuals dwell on maladaptive imagery. This series of studies evaluated imagery and verbal thought during experimentally induced rumination and distraction. In Study 1, imagery and verbal thought during rumination resulted in similar increases in negative affect. Greater imagery during distraction, on the other hand, was associated with greater decreases in negative affect while verbal thought was not related to affect change. Given that greater verbal thought was reported in the rumination condition and greater imagery was reported in the distraction condition, Study 2 evaluated whether the rumination/distraction induction was confounded by concurrent induction of imagery or verbal thought. The rumination prompts induced both rumination and verbal thought and the distraction prompts induced both distraction and imagery. Using a revised induction, Study 3 tested whether imagery and verbal thought during rumination and distraction impacted affective response. Rumination maintained negative affect and distraction relieved negative affect, regardless of the degree to which imagery or verbal thought was experienced. This paper provides evidence that imagery-based rumination is just as impairing as verbally-based rumination and highlights imagery-based distraction as a potentially effective alternative to rumination.     

Prospective and positive mental imagery deficits in dysphoria

We know less about positive mental imagery than we do about negative mental imagery in depression. This study examined the relationship between depressed mood and the subjective experience of emotion in imagined events; specifically, prospective imagery, and imagery in response to emotionally ambiguous stimuli. One hundred and twenty-six undergraduates completed measures of depression, imagery vividness for future events, and a homograph interpretation task in which they generated images and subsequently rated image pleasantness and vividness. As predicted, compared to low dysphoria, high dysphoria was associated with poorer ability to vividly imagine positive (but not negative) future events. These findings were augmented by the observation that high dysphorics provided lower pleasantness ratings of images generated in response to homographs they interpreted as positive. We suggest that an imbalance in the inability to vividly imagine positive but not negative future events may curtail the ability of high dysphorics to be optimistic. High dysphoric individuals are further disadvantaged: even when they interpret ambiguity positively, the resulting images they generate are associated with less positive affect. Therapeutic strategies that address both such positive-specific imagery biases hold promise for depression treatment innovation.     

Emotional cascade theory and non-suicidal self-injury: the importance of imagery and positive affect

Grounded in Emotional Cascade Theory, we explored whether rumination and multisensory imagery-based cognitions moderated the relationships between affect and both odds of non-suicidal self-injury (NSSI), and frequency of the behaviour. A sample of 393 university students completed self-report questionnaires assessing the constructs of interest. Contrary to expectations, rumination did not emerge as a significant moderator of the affect-NSSI relationship. However, the relationship between affect and frequency of NSSI was moderated by the use of imagery. Further, the relationship between negative affect and NSSI was moderated by positive affect, underscoring the need to consider both negative and positive affect in models of NSSI. Most youth who self-injured reported thinking in images while the urge to self-injure was strong, with 53% thinking in images at least half the time. Future work is needed to explore how positive and negative affect work in concert to govern NSSI, and how imagery might either exacerbate or reduce risk of NSSI.     

Recurrent involuntary imagery in people who stutter and people who do not stutter

Objective

To compare intrusive memories in groups of people who do (PWS), and who do not (PWNS), stutter.

Method

Twenty-one participants who stuttered and 21 matched controls were given a semi-structured interview which explored imagery in speaking situations. The data were analyzed using a Content Analysis approach. Other outcome measures were the Beck Anxiety Inventory, the Beck Depression Inventory, the Post Traumatic Stress Disorder, PTSD, Symptom Scale: Self-Report Version.

Results

Significantly more stuttering participants than control participants indicated both recurrent imagery and associated memories. Content Analysis revealed themes of disfluency, anxiety, negative social evaluation, self-focus and pressure to speak that were common to both groups’ reports. Additional themes of helplessness, shame, sadness and frustration were found only in the images and memories of the stuttering group. No group differences were evident for the number of sensory modalities involved in images and memories, or for ratings of their vividness or strength of associated emotions, or on self-reports of depression, anxiety and trauma.

Conclusions

Recurrent imagery about events in childhood is a potent factor in the memories of PWS. It is worth modifying interventions that have been successfully applied for treating social anxiety for use with people who stutter.Educational objectives: After reading this article, participants will be able to: (a) identify the role of intrusive memories in psychiatric disorders and stuttering; (b) investigate how DSM criteria can be employed with people who stutter; (c) employ anxiety instruments used for assessing psychiatric disorders for stuttering; (d) distinguish between the intrusive memories experienced by people who stutter, and people who do not stutter; (e) apply treatments for intrusive memories in psychiatric disorders to work with people who stutter.     

Individual differences in visual imagery determine how event information is remembered

Individuals differ in how they mentally imagine past events. When reminiscing about a past experience, some individuals remember the event accompanied by rich visual images, while others will remember it with few of these images. In spite of the implications that these differences in the use of imagery have to the understanding of human memory, few studies have taken them into consideration. We examined how imagery interference affecting event memory retrieval was differently modulated by spatial and object imagery ability. We presented participants with a series of video-clips depicting complex events. Participants subsequently answered true/false questions related to event, spatial, or feature details contained in the videos, while simultaneously viewing stimuli that interfered with visual imagery processes (dynamic visual noise; DVN) or a control grey screen. The impact of DVN on memory accuracy was related to individual differences in spatial imagery ability. Individuals high in spatial imagery were less accurate at recalling details from the videos when simultaneously viewing the DVN stimuli compared to those low in spatial imagery ability. This finding held for questions related to the event and spatial details but not feature details. This study advocates for the inclusion of individual differences when studying memory processes.     

Speaking of pain in Greek: Implications for the cognitive permeation of emotions

ABSTRACT

Although item-memory for emotional information is enhanced, memory for associations between items is often impaired for negative, emotionally arousing compared to neutral information. We tested two possible mechanisms underlying this impairment, using picture pairs: 1) higher confidence in one’s own ability to memorise negative information may cause participants to under-study negative pairs; 2) better interactive imagery for neutral pairs could facilitate associative memory for neutral pairs more than for negative pairs. Tested with associative recognition, we replicated the impairment of associative memory for negative pairs. We also replicated the result that confidence in future memory (judgments of learning) was higher for negative than neutral pairs. Inflated confidence could not explain the impairment of associative recognition memory: Judgements of learning were positively correlated with associative memory success for both negative and neutral pairs. However, neutral pairs were rated higher in their conduciveness to interactive imagery than negative pairs, and this difference in interactive imagery showed a robust relationship to the associative memory difference. Thus, associative memory reductions for negative information are not due to differences in encoding effort. Instead, interactive imagery may be less effective for encoding of negative than neutral pairs.
