Researchers hope that it will be able to test for age-related cognitive decline in the future. > The trial recruited 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.
