25. Analytic Eye Movement Patterns in Face Recognition are Associated with BetterPerformance and more Top-down Control of Visual Attention: an fMRI Study

Author

Chan, Cynthia Y.H., Wong, J.J., Chan, Antoni B., Lee, Tatia M.C., and Hsiao, Janet H.

Subjects
eye movement, functional magnetic resonanceimaging (fMRI), face recognition, analytic patterns, HiddenMarkov Model (HMM), top-down visual attention.
Abstract

Recent research has revealed two different eye movement pat-terns during face recognition: holistic and analytic. The pre-sent study investigated the neural correlates of these two pat-terns through functional magnetic resonance imaging (fMRI).A more holistic pattern was associated with more activation inthe face-selective perceptual areas, including the occipitalface area and fusiform face area. In contrast, participants us-ing a more analytic pattern demonstrated more activation inareas important for top-down control of visual attention, in-cluding the frontal eye field and intraparietal sulcus. In addi-tion, participants using the analytic patterns had better recog-nition performance than those showing holistic patterns. The-se results suggest that analytic eye movement patterns are as-sociated with more engagement of top-down control of visualattention, which may consequently enhance recognition per-formance.

29. Eye Movement Pattern in Face Recognition is Associated with Cognitive Decline in the Elderly

Author

Subjects
eye movement, aging, face recognition, holisticprocessing, cognitive ability, Hidden Markov Model (HMM).
Abstract

The present study investigated the relationship between eyemovement pattern in face recognition and cognitive performanceduring natural aging through modeling and comparingeye movement of young (18-24 years) and older (65-81 years)adults using Hidden Markov Model (HMM) based approach.Young adults recognized faces better than older adults, particularlywhen measured by the false alarm rate. Older adults’recognition performance, on the other hand, correlated withtheir cognitive status assessed by the Montreal Cognitive Assessment(MoCA). Eye movement analysis with HMM revealedtwo different strategies, namely “analytic” and “holistic”.Participants using the analytic strategy had better recognitionperformance (particularly in the false alarm rate) thanthose using the holistic strategy. Significantly more youngadults adopted the analytic strategy; whereas more olderadults adopted the holistic strategy. Interestingly, older adultswith lower cognitive status were associated with higher likelihoodof using the holistic strategy. These results suggest anassociation between holistic eye movement patterns and cognitivedecline in the elderly.
