Relating Infant Fixations to Adult Cortical Activation Patterns Using the Natural Scenes Dataset.

ABSTRACT: Visual attention develops rapidly across the first postnatal year, from reflexive eye movements driven by low-level stimulus properties to increasingly voluntary eye movements influenced by higher-order factors. To test the hypothesis that development reflects guidance by increasingly abstract features, we used representational similarity analysis to evaluate the representational link between gaze patterns (N = 47 5-7-month-old infants, N = 46 10-12-month old infants, N = 45 adults) and measurements of fMRI cortical activity patterns from adult participants as they viewed scenes from the Natural Scenes Dataset. We found that similarities across scenes for fixation patterns and neural activity patterns were significantly related only for low-level visual regions in younger infants but were
