Recent theories of Posttraumatic Stress Disorder (PTSD) suggest that memory dysregulation plays a crucial role in symptom maintenance. However, it is not clear which specific memory systems are involved in PTSD. In this study we used a visual implicit memory paradigm to examine memory bias in individuals with PTSD symptoms. Three hundred nineteen participants provided self-report measures of PTSD, anxiety and depression symptoms. Next they completed a visual clarity-rating task (Amir et al… Expand

Effects of Acute Cortisol Administration on Perceptual Priming of Trauma-Related Material
TLDR
The findings indicate that cortisol influences PTSD-relevant memory processes and thus further support the idea that administration of cortisol might be an effective treatment strategy in reducing intrusive reexperiencing. Expand
Perceptual processing advantages for trauma-related visual cues in post-traumatic stress disorder
TLDR
A perceptual processing bias for trauma-related stimuli may contribute to the involuntary triggering of intrusive trauma memories in PTSD. Expand

TLDR
Compared to the no-PTSD group, the PTSD group recorded fewer nontrauma memories, which were more overgeneral, more often from before the trauma or related to the trauma, were perceived as distant, and led to greater dwelling. Expand
Modification of cognitive biases related to posttraumatic stress: A systematic review and research agenda.
TLDR
Results showed that CBM can indeed modify cognitive biases and affect (analog) trauma symptoms in a training congruent manner and sketched a detailed research agenda targeting the challenges for CBM in posttraumatic stress. Expand
Perceptual processing during trauma, priming and the development of intrusive memories
TLDR
The results provide some support for the role of perceptual processing and perceptual priming in reexperiencing symptoms and were associated with lower verbal intelligence. Expand
Information Processing in PTSD: Evidence for Biased Attentional, Interpretation, and Memory Processes
This comprehensive review surveys current literature on information processing biases in posttraumatic stress disorder (PTSD). The review is organized by information processing systems includingExpand
Temporal allocation of attention toward threat in individuals with posttraumatic stress symptoms.
TLDR
The results suggest that individuals with PTSD may process trauma-relevant information more rapidly and efficiently than benign information. Expand
Combining clinical studies and analogue experiments to investigate cognitive mechanisms in posttraumatic stress disorder.
TLDR
This review illustrates how studies of trauma survivors and analogue studies with non-traumatized populations can be usefully combined and argues that a combination of both approaches is needed to investigate cognitive mechanisms in PTSD. Expand
Enhanced Priming for Trauma-Related Words Predicts Posttraumatic Stress Disorder
TLDR
Priming for accident-related words predicted PTSD at 6 months follow-up, even when initial symptom levels of PTSD and depression were controlled, in line with the hypothesis that enhanced priming for traumatic material contributes to the development of chronic PTSD. Expand
Effect of anxiety on memory for emotional information in older adults
TLDR
Older adults with anxiety tend to recognize less positive information and to present more negative emotions when remembering life events; while individuals without anxiety have a more positive experience of negative memories. Expand

Attentional and memory bias for emotional information in crime victims with acute posttraumatic stress disorder (PTSD).
TLDR
It is proposed that further studies are needed in order to elucidate whether acute PTSD Ss display a preattentive and implicit memory bias for trauma-related material, and suggest that acute PTSD subjects have an attentional andMemory bias for threat-relatedmaterial. Expand
A cognitive model of posttraumatic stress disorder.
TLDR
A cognitive model of persistence of PTSD is proposed that is consistent with the main clinical features of PTSD, helps explain several apparently puzzling phenomena and provides a framework for treatment by identifying three key targets for change. Expand

We used a perceptual identification paradigm to investigate whether Vietnam combat veterans with post-traumatic stress disorder (PTSD), compared to healthy combat veterans, exhibit an implicit memoryExpand

TLDR
It is suggested that aging Holocaust survivors with PTSD preferentially form new associations with trauma-related stimuli as compared with neutral stimuli. Expand
Memory for emotionally neutral information in posttraumatic stress disorder: A meta-analytic investigation.
TLDR
The results indicated that the association between PTSD and memory impairment appears to be robust, small to moderate in size, and stronger for verbal than for visual memory. Expand
Implicit memory bias for threat in posttraumatic stress disorder
We employed a noise judgment task to investigate implicit memory bias for threat in Vietnam veterans with and without posttraumatic stress disorder (PTSD). Subjects first heard neutral (e.g., “THEExpand
Neuropsychological function in college students with and without posttraumatic stress disorder
TLDR
The striking lack of differences in neuropsychological performance between the three groups suggests that college students with trauma exposure, regardless of the presence of PTSD symptoms, may be cognitively resilient. Expand
Trauma-related and neutral false memories in war-induced Posttraumatic Stress Disorder
TLDR
While the groups were equally susceptible to neutral critical lures, the PTSD group mistakenly recalled more war-related lures than the controls, and implications for accounts of false memories in terms of source-monitoring are discussed. Expand
Overgeneral autobiographical memory and traumatic events: an evaluative review.
TLDR
Across studies, there was no consistent association between trauma exposure and overgenerality, suggesting that trauma exposure is unlikely to be the primary mechanism leading to over generality. Expand
Enhanced perceptual priming for neutral stimuli occurring in a traumatic context: two experimental investigations.
TLDR
The role of perceptual priming in intrusions after traumatic events is supported and elaboration showed that elaboration reduced the enhanced perceptualPriming effect and the relative probability of reexperiencing symptoms. Expand
