In a new study from King’s College London, researchers found that a virtual reality test in which participants “go to the shops” could offer a potentially promising way of effectively assessing functional cognition, the thinking and processing skills needed to accomplish complex everyday activities.
The research uses a novel virtual reality shopping task called “VStore” to measure cognition, which asks participants to take part in tests designed to mirror the real world.
Researchers hope that it will be able to test for age-related cognitive decline in the future.
In the study, the team tested 142 healthy individuals aged 20-79 years.
Each participant was asked to “go to the shops,” first verbally recalling a list of 12 items, before being assessed for the amount of time it took to collect the items, as well as select the corresponding items on a virtual self-checkout machine, pay, and order coffee.
Cognition tests, such as those used to measure the deficits present in several neuropsychiatric disorders including Alzheimer’s disease, schizophrenia, and depression, are traditionally time-consuming and onerous.
Vstore—the technology that the researchers used in this study—is designed to overcome these limitations to provide a more accurate, engaging, and cost-effective process to explore a person’s cognitive health.
The team says the immersive environment (a virtual shop) mirrored the complexity of everyday life and meant that participants were better able to engage brain structures that are associated with spatial navigation, such as the hippocampus and entorhinal cortex, both of which can be affected in the early stages of Alzheimer disease.
Researchers were able to establish that Vstore effectively engages a range of key neuropsychological functions simultaneously.
This suggests that the functional tasks embedded in virtual reality may engage a greater range of cognitive domains than standard assessments.
The team says virtual Reality appears to offer them significant advantages over more traditional pen-and-paper methods.
The simple act of going to a shop to collect and pay for a list of items is something that we are all familiar with, but also actively engages multiple parts of the brain.
The study suggests that VStore may be suitable for evaluating functional cognition in the future. However, more work needs to be done before they can confirm this.
