Impairment in active navigation from trauma and Post-Traumatic Stress Disorder
Open accessAbstract
The study investigated the impact of trauma exposure and of Post-Traumatic Stress Disorder (PTSD) on spatial processing and active navigation in a sample (n=138) comprising civilians (n=91), police officers (n=22) and veterans (n=27). Individuals with previous trauma exposure exhibited significantly poorer hippocampal-dependent (allocentric) navigation performance on active navigation in a virtual environment (the Alternative Route task) regardless of whether or not they had PTSD (scoring above 20 on the PTSD Diagnostic Scale). No effect of trauma exposure was found in static perspective taking (the Four Mountains task). Moreover, an associative information processing bias in those with PTSD interfered with ability to use hippocampal-dependent processing in active navigation. This study provides new evidence of impaired active navigation in individuals with trauma exposure and highlights the importance of considering the relationship between trauma and spatial processing in clinical and occupational settings.

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.
