Though he can articulate correctly, the patients are unable to put his thoughts into symbolic form as spoken or written words. The defect may be for varying occasional misplacement or misuse of words. Emotional speech is less affected than propositional speech. There is a marked tendency for the patients to continue to use one word or phrase though he is attempting to express different ideas. This repetition is called perseveration. The defect can usually be recognized readily during ordinary conversation with the patient but in very mild cases it may be necessary to try such tests as showing him a large series of objects and asking him to name them. Though he fails to do so, he will immediately recognize the correct name when it is suggested to him. This type of defect occurs with a lesion at the poster end of the third frontal convolution (Broca’s area) and the lower part of the precentral gyrus.
