Poster Summary

Delivering cognitive tests on a range of modalities, including smartphones, can increase access to memory screening tools for people at risk of memory impairment in Alzheimer’s and dementia. We have developed a prototype version of our Paired Associates Learning (PAL) test that can be delivered on a smartphone. We tested the smartphone version of PAL by recruiting healthy people over the age of 50 to evaluate usability and comparability in individuals within a population at risk of Alzheimer’s and dementia. 50% of the participants completed the task on a desktop first then a smartphone, the other 50% did the task on a smartphone first. The smartphone and desktop versions of PAL were shown to be highly correlated although average performance was better on a desktop. The usability questionnaire indicated that participants preferred using PAL on a desktop as it was easier to use and more enjoyable. Improvements to the smartphone delivered PAL will need to consider box size, layout and positioning and impact on performance variability.
