Visual Paired Comparison
The experimental task is an adapted version of the Visual Paired Comparison methodology described in different articles trying to automatically assess dementia such as Bott et al, (2017) and Crutcher et al, (2009).

This eye-tracking paradigm is known as the "Visual Paired Comparison" or VPC. During the familiarization phase participants are shown two identical stimuli for the first time. Then in a test phase participants are simultaneously shown one of the previously seen 'familiar' stimuli and one 'novel' stimulus.
