About Paper:

Pointing is a foundational gesture in infants' cognitive and social development. Studies have shown that infants follow human pointing gestures in a spatial cueing paradigm as early as four months. However, most overlook the social cues accompanying pointing naturally. In our pointing study, we employ video clips (from a prior study) captured from an infant's egocentric perspective using a head-mounted eye tracker, depicting a parent pointing to one of two objects in a book.These videos vary in social cues present, such as the parent's face, finger tapping, and hand movements preceding pointing. Data is being collected from 6- and 9-month-old infants using an Eyelink eye tracker to record their gaze. Infants first watch 10-s videos in which a parent points to one object in a book, followed by test trials in which the pointed-at object and a non-pointed-at or novel object are presented side-by-side. Infants' memory for the pointed-at object is measured using a preference score, calculated as the duration of looking at the non-pointed-at or novel object divided by the total looking time at both objects. We hypothesize that these social cues in the videos will capture infants' attention and enhance infants' learning of pointed-at objects.
