THE object of this paper is to carry the analysis of stutter phenomena deeper than before. In my last year's paper I showed that chronologically the diagnosis of dyslalia mounted step by step from a material external affair, up through the nerves until we came to the basal ganglia. I showed conclusively that it was an involvement that did not exist in any of these places. I further took steps to demonstrate and present evidence that indicated that dyslalia was in its essence some trouble with the personality. I mean by this: that the trouble was located in the nervous system beyond the lower sensory areas of the sensorium; and also above the lower motor areas on the motor side. By the broad term "personality" I mean the total of the activities and interrelations of mental activities that occur above our lower sensory and motor areas. The paper of last year clearly located the trouble vaguely in this region of the personality. Since that time I have been interested to ascertain just what the nature of this changed personality is. In order to do so, I have carried on an investigation that has reached interesting conclusions. To me it is new truth. It may not be all the truth, but as far as it goes, and as for what it is, it surely is truth and a new finding! This research is an effort to show not only where it is but WHAT IT IS. The method was as follows: For the purpose of finding out some of the activities going on in the area of collaboration during speech, I asked my stuttering patients two simple questions. I thus found that their methods of collaboration complied to a certain mental type. Then I carried this same method into the study of normal individuals in the collaboration of their ideas, just before and during speech in order to establish a norm; and to see whether or not it differed from my preliminary test of stuttering cases just mentioned. It did, and therefore I formulated a series of questions in order to pin the type of collaboration down to certain fields of mental action. To make this clear, let me present an outline of these different steps in tabular form.
