*Repetition of Previous Stimulus.*—Here we place any reaction which is a repetition of any previous stimulus from amongst the ten next preceding, at the same time placing *repetition of preceding stimulus* under a separate heading.
*Neologisms.*—Here we place the newly coined words, so commonly given by the insane, excepting such as possess a sound relationship to the stimulus word, for which, as already stated, a special place in the classification has been provided.
Neologisms might be divided into three types, as follows: (1) those which arise from ignorance of language (comfort—uncomfort, short—diminiature); (2) distortions of actual words, apparently of pathological origin and not due to ignorance (hungry—foodation, thief—dissteal); and (3) those which seem to be without any meaning whatever (scack, gehimper, hanrow, dicut). It is, however, impossible to draw clear-cut distinctions between these types, and for this reason we have made no provision in our classification for such division.
*Unclassified Reactions.*—This group is important, in the first place, because it is numerically a large one, and in the second place, because it contains certain fairly definite types of reactions which are placed here for the sole reason that we have not been able to find strictly objective criteria for their differentiation from other types.
It has already been stated that the frequency tables, even together with the appendix, fail to exhaust all normal possibilities of association, so that a certain small number of perfectly normal reactions must fall into the unclassified group. We submit the following examples:
music—listen smooth—suave sour—curdled earth—mound
Another type of reactions found in the unclassified group, though also normal, yet not obviously so until explained by the subject, is represented by those which originate from purely personal experiences, such as the following, given by normal subjects:
blossom—T….. hammer—J…..
The first of these reactions is explained by the subject's acquaintance with a young lady, Miss T…., who has been nick-named "Blossom," and the second is explained by the subject's having among her pupils at school a boy by the name of J…. Hammer.
It would be difficult to estimate the proportion of such reactions in the unclassified group, but we have gained the general impression that it is small. An attempt to place them in a separate group could be made only with the aid of explanations from the subjects; such aid in the case of insane subjects is generally unreliable. Moreover, to class these reactions as strictly normal would perhaps be going too far, since their general value is obviously inferior to that of the common reactions; and in any case in which they are given in unusually large numbers they must be regarded as manifestation of a tendency to depart from the normal to the extent to which they displace common reactions. The next type of reactions met with in the unclassified group is characterized by a peculiarly superficial, or non-essential, or purely circumstantial relationship to the stimulus. Such reactions, though occasionally given by normal subjects, are more often given by insane ones, and seem to be somewhat characteristic of states of mental deterioration which are clinically rather loosely described as puerilism. We offer the following examples, given by normal subjects:
