Results from head-camera studies linking visual size and centering of a named object to learning. Panels a and b show examples head-camera images during two naming moments when later testing showed the child had learned the name (a) and not learned the name (b). Panels c and d show the image size (% pixels) of the named target object (black) and the mean of the other in-view, competitor objects (gray) for the 20-second window around the naming utterance (utt) for naming moments that led to the learning of the object name (c) or did not (d). Panels e and f show the overlap of the image of the named target (black) and the mean overlap of the images of the competitor objects (gray) with the center of the head-camera image for the 20-s window around the naming utterance (utt) for naming moments that led to the learning of the object name (e) or did not (f).
