Накратко на български

Връзката между начина, по който помним пространството при травма (например дали виждаме събитието от собствените си очи или обективно), се тества чрез виртуална реалност. Разбирането на този механизъм помага за намаляване на болезнените спомени при посттравматично стресово разстройство.

Looking at it from a different angle: The role of viewpoint-dependency in traumatic intrusions.

Emotional memories guide our behaviour and are critical for our survival. However, they can become dysfunctional and contribute to the development of mental disorders such as post-traumatic stress disorder (PTSD), characterized by distressing intrusive memories. Although it is well-established that emotional experiences can have a memory-enhancing effect, it is not fully understood when and why emotional memories become maladaptive. According to Dual Representation Theory, intrusive memories arise when spatial representations of the traumatic event are insufficiently allocentric - i.e., independent of one’s viewpoint, coding features relative to each other rather than to the viewer. This project consisted of a series of experimental studies with healthy participants, in which we tested the role of allocentric memory formation in an aversive Virtual Reality (VR) scenario that provokes intrusive memories. VR makes spatial elements and viewpoints fully controllable. We attempted to exploit these possibilities in order to measure and train allocentric memory during and after emotionally challenging experiences, with the ultimate aim of reducing intrusive memories.

Цел на проекта

Many victims of psychological trauma suffer from recurrent intrusive trauma memories. According to Dual-Representation Theory (DRT), intrusive memories reflect functional deficiencies in the brain’s hippocampal system, which fails to translate the egocentric perceptual impressions of the trauma into viewpoint-independent (or allocentric) spatial representations. This proposal tests this assumption and explores allocentric memory training as a potential novel intervention against intrusive memories.I propose to induce intrusive memories in healthy participants using aversive scenarios in real-time 3D Virtual Reality, and to afterwards test location memory from the original versus a shifted viewpoint, requiring allocentric memory. Study 1 links allocentric memory to intrusion levels. Study 2 explores the potential of an allocentric memory training. Furthermore, both studies will assess the potentially moderating role of hormonal and sympathetic stress markers known to affect hippocampal learning.The project will provide novel insights into mechanisms of trauma memory, with potentially important implications for theory and treatment. It will be conducted in Prof. Chris Brewin’s research group at University College London (UCL) that is renowned for empirical tests of DRT specifically, and for world-leading expertise in clinical, experimental, neurocognitive and neuroendocrine approaches to psychology, providing an inspiring environment that perfectly fits the interdisciplinary character of this project.
