Fig. 5From: Impact of mask use on face recognition: an eye-tracking studyCorrelation between the change in conditional entropy of the third fixation given the second fixation due to mask use during recognition (unmasked–unmasked condition minus unmasked–masked condition; more positive change indicates larger change toward lower entropy and thus more consistent transition with mask use) and the corresponding performance impairment in d′: The more change toward low-entropy/more consistent gaze transition behavior, the less the performance impairmentBack to article page
