Two strongly right-handed patients with aprosodia following left hemisphere strokes are described. These patients appear to represent the aprosodia analogue of crossed aphasia--crossed aprosodia--and provide further evidence that the organization of the effective components of language is functionally and anatomically similar to the organization of the propositional components of language in the brain. In addition, both patients evidenced "double-crossed" agraphia involving the left hand.
