Atypical exploration behaviors recorded using digit-tracking. a Example of image exploration by a patient suffering from hemispatial neglect (Hemi. Neglect) due to right-parietal lobe damage following stroke and a control subject. The right panels represent the average spatial distribution of the explorations recorded for 32 images in a single examination session. The spatial attention bias can be precisely quantified: for the control subject, 49.6% of their exploration is on the right side of the display (corresponding to a Z-score of −0.1, centile 45, according to a reference population, N = 22), whereas for the patient, 82.7% of the exploration has been recorded on the right side of the display (corresponding to a Z-score of 9.8, centile > 99.999). b Exploration of an image with social content by a 14-year-old non-verbal autistic child compared to a neurotypical control subject. The patient adopts an exploration strategy which avoids human faces (red frame), whereas these are the most explored scene elements in the control population. Please note that original faces have been modified to hide individuals’ identity.
