Abstract

Involuntary images and visual memories are prominent in many types of psychopathology. Patients with posttraumatic stress disorder, other anxiety disorders, depression, eating disorders, and psychosis frequently report repeated visual intrusions corresponding to a small number of real or imaginary events, usually extremely vivid, detailed, and with highly distressing content. Both memory and imagery appear to rely on common networks involving medial prefrontal regions, posterior regions in the medial and lateral parietal cortices, the lateral temporal cortex, and the medial temporal lobe. Evidence from cognitive psychology and neuroscience implies distinct neural bases to abstract, flexible, contextualized representations (C-reps) and to inflexible, sensory-bound representations (S-reps). We revise our previous dual representation theory of posttraumatic stress disorder to place it within a neural systems model of healthy memory and imagery. The revised model is used to explain how the different types of distressing visual intrusions associated with clinical disorders arise, in terms of the need for correct interaction between the neural systems supporting S-reps and C-reps via visuospatial working memory. Finally, we discuss the treatment implications of the new model and relate it to existing forms of psychological therapy.

  • Intrusive memories of unpleasant experiences are common in most psychiatric disorders.

    “Whereas it was originally believed that intrusive memories of unpleasant experiences were a unique symptom of PTSD, it is now known that this symptom is common in most psychiatric disorders [7].”

    From Memory and Forgetting (2018) · cites this paper as [7]

    The Naturalistic Studies summary (page not provided) says intrusive images and memories are common in many disparate psychological conditions and are often linked to adverse events. This supports their occurrence beyond PTSD, but the paper says “many,” not “most,” disorders; it also discusses intrusive images as well as memories of unpleasant experiences. (LLM, conf=0.82)

  • All clinical theories of PTSD require the existence of a specialized long-term perceptual memory system that is functionally independent of episodic memory.

    “All these theories therefore require the existence of a specialized longterm perceptual memory system that is functionally independent of episodic memory.”

    From Episodic memory, perceptual memory, and their interaction: Foundations for a theory of posttraumatic stress disorder. (2014) · cites this paper as Brewin, Gregory, Lipton, & Burgess, 2010

    The Abstract (page not available in our copy) says some influential clinical theories propose a second sensory memory system, supporting that part of the claim. It does not say all PTSD theories require one; it also describes a clinical account based on increased stimulus priming and contrasts single-system accounts. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Perceptual memories consist of 'sensation-near' representations ('S-reps') which are the product of processing in the dorsal visual stream, insula, and amygdala, and which are specialized for action on the environment.

    “The authors suggest that these perceptual memories consist of 'sensation-near' representations ('S-reps') which are the product of processing in the dorsal visual stream, insula, and amygdala, and which are specialized for action on the environment.”

    From Episodic memory, perceptual memory, and their interaction: Foundations for a theory of posttraumatic stress disorder. (2014) · cites this paper as Brewin, et al., 2010

    In 'A Neurocognitive Model of Healthy Memory and Imagery' (page unavailable), the paper defines S-reps as low-level, sensation-based representations. The revised theory's Summary (page unavailable) associates them with the dorsal visual stream and its connections to the amygdala and insula. The passages do not say that S-reps are specialized for action on the environment. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Very high levels of stress lead to a corresponding reduction of activity in the ventral visual stream and medial temporal lobe, where elements of objects and scenes are normally bound together and encoded in an abstract form.

    “Very high levels of stress also lead to a corresponding reduction of activity in the ventral visual stream and medial temporal lobe, where the elements of objects and scenes are normally bound together and encoded in an abstract form.”

    From Memory and Forgetting (2018) · cites this paper as [7]

    In “Intrusive Images in Posttraumatic Stress Disorder” (page unavailable), the paper says high stress has deleterious effects on hippocampal functioning and predicts weaker contextual representations. Its Summary (page unavailable) links those representations to the ventral visual stream and medial temporal lobe. It does not establish the claimed corresponding reduction in activity across both regions; that states the proposed mechanism more definitively than the paper does. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • According to the revised dual representation theory of PTSD, flashbacks depend on a stress-related excess of activity in the dorsal visual stream.

    “According to the revised dual representation theory of PTSD [7, 15], flashbacks depend on a stress-related excess of activity in the dorsal visual stream, which is specialized for creating images of the environment from a first-person (egocentric) perspective that can be used to direct immediate motor responses to threat.”

    From Memory and Forgetting (2018) · cites this paper as [7]

    In “Intrusive Images in Posttraumatic Stress Disorder” (page unavailable), the revised model links flashbacks to enduring representations formed during extreme stress, and the Summary associates those representations with the dorsal visual stream. But the paper specifies a second necessary condition—their lack of integration with contextual representations—and does not state that flashbacks depend on excess dorsal-stream activity alone. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
