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: _music--town_ _sickness--summer_ _child--unknown_ _house--enter_ Still another type of reactions to be considered in this connection consists of words which are in no way related to the corresponding stimulus words, but which arise from _distraction_ of the subject by surrounding objects, sounds, and the like. In some cases the experimenter may be able to judge from the direction of the subject's gaze, from a listening attitude, and so on, that certain reactions are due to distraction. In other cases, particularly in cases of normal subjects, the fact that certain reactions are due to distraction may be determined by questioning the subject on this point immediately after making the test; In work with insane subjects, as we have several times had occasion to point out, such aid is generally not available. The group of unclassified reactions includes also one more type of reactions which are of great importance both numerically and otherwise. These are the *incoherent reactions*, that is to say, reactions which are determined neither by the stimulus words, nor by the agency of perseveration, nor by distraction.
