Figure 2.

Example of an image used to induce visual search during the training period. The child is asked to search for the object/person shown below the image and to point to it with a laser pointer. In this example the first person to search for was a boy dressed in red, then the boy with the blue t-shirt, and so on until the child had found all the people shown below the image. The persons in yellow circles were used at the beginning of the training to ensure that the child had understood the task correctly. After this scene, other scenes were presented, and the child had to conduct an image/person search for 10 min.
