Cognitive mapping deficits in XXXX : Evidence from clinical correlates of visuospatial transformations.

@entity1 @entity1109 @entity161
UNASSIGNED: The 'cognitive mapping' component of spatial cognition, namely - the allocentric/egocentric function and its relation to symptoms in @entity161 is relatively unexplored. In this study, we compared @entity161 @entity1 (N=44) to demographically-matched healthy controls (N=43) using computer-administered visuospatial transformation tasks with egocentric and allocentric components and analyzed their correlation with symptoms. Significant diagnosis X task-type interaction effect was seen on task accuracy. @entity1 performed significantly worse than controls in the allocentric letter rotation task (LRT) but not in the egocentric @entity1 rotation task (PRT). Accuracy in the LRT was significantly lesser than in PRT among @entity1 but not among controls. @entity1 were significantly slower as compared to controls in both tasks. Both groups took longer to perform PRT as compared to LRT. LRT accuracy showed significant negative correlation with @entity1109 as well as negative symptoms scores. Angle of rotation, perspective (front-facing/back-facing), orientation (mirrored/normal), and stimulus type (letter/number) were found to significantly influence performance in both groups of subjects. The present data support the finding that there is a differential impairment of allocentric abilities in @entity161 @entity1 . Further systematic research in this area may facilitate better understanding of @entity161 pathogenesis.
