Do “knowledge attributions” involve metarepresentation just like belief attributions do?

The authors distinguish knowledge and belief attributions, emphasizing the role of the former in mental-state attribution. This does not, however, warrant diminishing interest in the latter. Knowledge attributions may not entail mental-state attributions or metarepresentations. Even if they do, the proposed features are insufficient to distinguish them from belief attributions, demanding that we first understand each underlying representation.
