Cognitive Memory Assessment in 2D and 3D Virtual Reality
(2021) KOGM20 20211Cognitive Science
- Abstract
- The ultimate goal of memory research is to deconstruct how humans form representations of real-life experiences accessible in the future. However, this can be challenging to investigate thoroughly while maintaining both naturalistic exposure and experimental control. To tackle this issue, a platform for cognitive memory assessment in virtual reality (VR) has been constructed. The platform portrays photorealistic environments in which everyday objects are encoded in terms of appearance and spatial positioning. Tests for object recognition and spatial memory are integrated into the behavioral VR task. How we perceive the world differs significantly depending on how immersed we are in the experience and moreover, our memory depends on the... (More)

Tests for object recognition and spatial memory are integrated into the behavioral VR task. How we perceive the world differs significantly depending on how immersed we are in the experience and moreover, our memory depends on the familiarity of the form the content to be remembered is presented in. As a second aspiration, I sought to find out whether 3D through stereoscopic rendering effects specifically aids memory. Results showed quicker identification although no difference in accuracy for object recognition in 3D compared to 2D. Furthermore, spatial memory measured by precise distances was improved in stereoscopic VR perception. In conclusion, a robust, versatile, and unique VR platform has been built, ready to be applied to neuroimaging research on memory, and is perhaps of special interest for researchers focusing on cognitive memory decline such as Alzheimer's disease.
