► A patient with a selective conceptual deficit for man-made objects and actions. ► No disproportionate impairment of functional compared to sensory knowledge. ► No disproportionate impairment for manipulation compared to functional knowledge. ► Manipulable items were no more impaired than non-manipulable items. ► Hypothesis of a domain-specific conceptual system for man-made objects and actions.
