FIGURE 2.

Illustration of the scene children view while sitting in front of the apparatus. In the actual studies, children view a camera image of the adult carrying out her task. Since her behavior is never identical across participants, the illustrations here represent prototypical poses during specific phases of the study. The (left) represents the time during which the adult carried out her task, e.g., stacking cans, standing behind the table. The (right) represents the time the adult spent reaching for the dropped object. Each phase can last from a few seconds to several minutes. During that time, the eye tracker records children’s gaze that can be mapped onto the illustrations to identify focal points of attention. The resulting focus maps reveal areas of low (blue) and high (red) attention.
