Some relations of grammar and lexicon in aphasia.

A new form of a Sentence Order Test was applied to a group of Broca's, Wernicke's and total aphasics. Sentences cut into three movable cards should be put together. Some of the sentences could be arranged in two different ways. Broca's aphasics prefered to order the parts according to a logical string of lexical items neglecting the grammatical errors. Wernicke's aphasics arranged the material according to the grammatical structure being unaware of the odd lexical meaning. Most of the results of total aphasics were similar to those of Wernicke's aphasics others however performed like Broca's aphasics.
