Native contours

In this experiment [Hochberg & Brooks, 1962], a human baby was raised until the age of 19 months under the constant supervision of his parents who avoided exposing the child to line-drawings or two-dimensional pictures of any kind. Although the baby accidentally had opportunities to glance at some pictures on a few occasions, at no point was the content of a picture ever named to him or was other attention drawn to it. All of the baby’s playthings were chosen so that they had solid coloring and no two-dimensional patterning of any kind. Finally, at the age of 19 months the child was shown some line-drawings for the first time, including those illustrated in Figure 1-3. The child was immediately to recognize objects in these drawings with no reported difficulty, and performed equally well when identifying the contents of black-and-white photographs.
