Developmental changes in face visual scanning in XXXX as assessed by data-based analysis.

@entity1 @entity735 @entity72 @entity2438
Individuals with @entity72 ( @entity72 ) present reduced visual attention to faces. However, contradictory conclusions have been drawn about the strategies involved in visual face scanning due to the various methodologies implemented in the study of facial screening. Here, we used a data-driven approach to compare @entity1 and adults with @entity72 subjected to the same free viewing task and to address developmental aspects of face scanning, including its temporal patterning, in healthy @entity1 , and adults. Four groups (54 subjects) were included in the study: typical adults, typically developing @entity1 , and adults and @entity1 with @entity72 . Eye tracking was performed on subjects viewing unfamiliar faces. Fixations were analyzed using a data-driven approach that employed spatial statistics to provide an objective, unbiased definition of the areas of interest. Typical adults expressed a spatial and temporal strategy for visual scanning that differed from the three other groups, involving a sequential fixation of the right eye (RE), @entity735 . Typically developing @entity1 , adults and @entity1 with @entity2438 exhibited similar fixation patterns and they always started by looking at the RE. @entity1 (typical or with @entity72 ) subsequently looked at the LE or the mouth. Based on the present results, the patterns of fixation for static faces that mature from childhood to adulthood in typical subjects are not found in adults with @entity72 . The atypical patterns found after developmental progression and experience in @entity72 groups appear to remain blocked in an immature state that cannot be differentiated from typical developmental @entity1 patterns of fixation.
