Drawings of the same household by an individual with DTD (A), their unaffected spouse (B), and their unaffected child (C). Notice the lack of metric spatial information present in the drawing in (A), in which only the rough order of rooms is reported. Individuals with DTD are often using a verbal strategy when map-sketching: reporting the order of landmarks experienced on a known route, and using that sequence information to produce a rough map.
