- This brief commentary reflects on the current Special Issue on "Cognitive Bias Modification Techniques: Current findings and future challenges". We consider past perspectives, present findings and future applications of "cognitive bias modification" (CBM) training procedures. In an interview with Marcella L. Woud, Bundy Mackintosh responds with her thoughts as an experienced 'traveler', given her pioneering work at the early stages of CBM research. Elaine Fox provides an overview of developments since the last special issue on CBM that she helped to co-edit in 2009, and Emily A. Holmes reflects on what might need to be done in order to translate the results of CBM research into therapeutic practice. All three conclude that, much as we might wish for a CBM 'tardis' time travel machine, there is much basic and translational science work to be done before the fruits of CBM research will be seen in the clinic. Systematic, thorough, and collaborative efforts will be needed, and we urge researchers to pay more attention to developing appropriate methodologies to enable the 'transfer' of training to clinical symptoms. Given the colossal clinical need to innovate and develop the content and delivery of mental health treatments, CBM research needs to keep travelling slowly, surely, and further. It is important to note that given low intensity of delivery, even studies with small effect sizes may be beneficial at a public health level. We should keep going, but retain strong roots in experimental psychopathology to maintain the quality and understanding of how cognitive factors are central to mental health and to the effectiveness of therapeutic interventions.

- Therapists often assume a special association between mental imagery and emotion, though empirical evidence has been lacking. Using an interpretation training paradigm, we previously found that imagery had a greater impact on anxiety than did verbal processing of the same material (Holmes & Mathews, 2005). Although the finding of a differential impact of imagery versus verbal processing of negative material was replicated, findings did not extend to benign material. Results therefore left open the question of whether there may be a special association between imagery and positive emotion. The current experiment examined positive interpretation training. Numerous scenarios were presented with initial ambiguity as to positive outcome or not, with final information then yielding consistently positive resolutions. Participants were asked to either imagine these positive events or to listen to the same descriptions while thinking about their verbal meaning. Those participants in the imagery condition reported greater increases in positive affect and rated new descriptions as being more positive than did those in the verbal condition. Results suggest that positive training can be enhanced through imagery as opposed to verbal processing. This study also provides the first test of a standardized intervention using an "interpretive bias training" paradigm to improve positive mood.

- The hypothesis that mental imagery is more likely to elicit emotion than verbal processing of the same material was investigated in two studies. Participants saw a series of pictures, each accompanied by a word, designed to yield a negative or benign meaning when combined. Participants were either free to combine the picture and word as they wished (Experiment 1) or instructed to integrate them using either a descriptive sentence or a mental image (Experiment 2). Emotional response was consistently greater following imagery than after producing a sentence. Experiment 2 also demonstrated the causal effect of imagery on emotion and evaluative learning. Additional participants in Experiment 2 described aloud their images/sentences. Independent ratings of descriptions indicated that, as well as being more emotional, images differed from sentences elicited by identical cues by greater similarity to memories, and greater involvement of sensations and specific events. Results support the hypothesis that imagery evokes stronger affective responses than does verbal processing, perhaps because of sensitivity of emotional brain regions to imagery, the similarity of imagery to perception, and to autobiographical episodes.

- The types of appraisals that follow traumatic experiences have been linked to the emergence of posttraumatic stress disorder (PTSD). Could changing reappraisals following a stressful event reduce the emergence of PTSD symptoms? The present proof-of-principle study examined whether a nonexplicit, systematic computerized training in reappraisal style following a stressful event (a highly distressing film) could reduce intrusive memories of the film, and symptoms associated with posttraumatic distress over the subsequent week. Participants were trained to adopt a generally positive or negative poststressor appraisal style using a series of scripted vignettes after having been exposed to highly distressing film clips. The training targeted self-efficacy beliefs and reappraisals of secondary emotions (emotions in response to the emotional reactions elicited by the film). Successful appraisal induction was verified using novel vignettes and via change scores on the Post Traumatic Cognitions Inventory. Compared with those trained negatively, those trained positively reported in a diary fewer intrusive memories of the film during the subsequent week, and lower scores on the Impact of Event Scale (a widely used measure of posttraumatic stress symptoms). Results support the use of computerized, nonexplicit, reappraisal training after a stressful event has occurred and provide a platform for future translational studies with clinical populations that have experienced significant real-world stress or trauma.

Reducing analogue trauma symptoms by computerized reappraisal training - Considering a Cognitive prophylaxis?

- Background and objectives: Distressing intrusions are a hallmark of posttraumatic stress disorder (PTSD). Dysfunctional appraisal of these symptoms may exacerbate the disorder, and conversely may lead to further intrusive memories. This raises the intriguing possibility that learning to 'reappraise' potential symptoms more functionally may protect against such symptoms. Woud, Holmes, Postma, Dalgleish, and Mackintosh (2012) found that 'reappraisal training' when delivered after an analogue stressful event reduced later intrusive memories and other posttraumatic symptoms. The present study aimed to investigate whether reappraisal training administered before a stressful event is also beneficial. Methods: Participants first received positive or negative reappraisal training (CBM-App training) using a series of scripted vignettes. Subsequently, participants were exposed to a film with traumatic content. Effects of the CBM-App training procedure were assessed via three distinct outcome measures, namely: (a) post-training appraisals of novel ambiguous vignettes, (b) change scores on the Post Traumatic Cognitions Inventory (PTCI), and (c) intrusive symptom diary. Results: CBM-App training successfully induced training-congruent appraisal styles. Moreover, those trained positively reported less distress arising from their intrusive memories of the trauma film during the subsequent week than those trained negatively. However, the induced appraisal bias only partly affected PTCI scores. Limitations: Participants used their own negative event as a reference for the PTCI assessments. The events may have differed regarding their emotional impact. There was no control group. Conclusions: CBM-App training has also some beneficial effects when applied before a stressful event and may serve as a cognitive prophylaxis against trauma-related symptomatology.
