How we see relations: The case of containment and support.

To navigate and act in the environment, it is necessary to recognize objects and the relationships between them. Recognition of objects in visual scenes is rapid and automatic. Are relations between objects in a scene also extracted rapidly and automatically during perception? Here, we considered containment and support, two relations that are fundamental to our understanding of the physical world. Using frequency-tagging electroencephalography on human subjects, we measured stimulus-driven neural responses during rapid visual presentation of images (4 Hz), with a periodic oddball structure to
