Researchers create virtual reality cognitive assessment
INA – Baghdad
Virtual reality isn't just for gaming. Researchers can use virtual reality, or VR, to assess participants' attention, memory and problem-solving abilities in real world settings. By using VR technology to examine how folks complete daily tasks, like making a grocery list, researchers can better help clinical populations that struggle with executive functioning to manage their everyday lives.
Lead author Zhengsi Chang is a Ph.D. student that works in the lab of Daniel Krawczyk, Ph.D., deputy director of the Center for BrainHealth. Along with Brandon Pires, a researcher at Texas Tech University Health Sciences Center, the team investigated whether VR can be used to effectively test a participant's executive functional load, or how much information a person can process to achieve a goal. Their findings were recently published in Computers in Human Behavior Reports.
The researchers adapted the Virtual Reality Functional Capacity Assessment Tool's (VRFCAT) "kitchen test", where participants plan a trip to the grocery store by comparing ingredients in kitchen cabinets to a list of recipes. Making a grocery list is an everyday task and should therefore accurately capture participants' daily working memory and performance. "Function-led tasks using VR technology allow us to maintain a balance between ecological validity and experimental control," said Chang.
