A rehabilitative task consisting in producing words which belong to the same phonemic category or the same semantic field.

In discussing jargonaphasia, he insisted that it did not signify a dementia but only a specific type of forgetting. He pointed out that ideation and the memory for words must be distinguished from each other. Ideation is evoked by the perception of physical objects and the action of the sensory nerves. The evocation of words follows ideation, and hence additional neural energy or action is required for it to take place. Therefore, it is understandable that brain disease could impair the memory for words but leave ideation intact so that a patient might be able to recognize an object and know its significance, yet misname it or not be able to name it at all.
