We introduce a novel application of a computerized version of the Trail Making Test (c-TMT), designed to track hand and eye movements during multiple trials to tackle the main limitations of the classic pen-and-pencil version. Adults with mild cognitive impairment (MCI) and a matched control group were studied to obtain fine-grained metrics during the task. Statistically significant differences between groups were found in the scanpath length, while more traditional measures, such as time to complete trials, were not discriminative. We advocate for using new complementary measurements and digital tools in neuropsychology to improve the precision of neuropsychological tests.
