After deeper reflection one realizes that, although there is a diversity in the psychic material and in the duration of time of the two phenomena, yet these are by far outweighed by the conformities between the two. In both cases we deal with the failure of remembering: what should be correctly reproduced by the memory fails to appear, and instead something else comes as a substitute. In the case of forgetting a name there is no lack of memory function in the form of name substitution. The formation of a concealing memory depends on the forgetting of other important impressions. In both cases we are reminded by an intellectual feeling of the intervention of a disturbance, which in each case takes a different form. In the case of forgetting of names we are aware that the substitutive names are incorrect, while in concealing memories we are surprised that we have them at all. Hence, if psychologic analysis demonstrates that the substitutive formation in each case is brought about in the same manner--that is, through displacement along a superficial association--we are justified in saying that the diversities in material, in duration of time, and in the centring of both phenomena serve to enhance our expectation, that we have discovered something that is important and of general value. This generality purports that the stopping and straying of the reproducing function indicates more often than we suppose that there is an intervention of a prejudicial factor, a tendency which favours one memory and at the same time works against another. The subject of childhood memories appears to me so important and interesting that I would like to devote to it a few additional remarks which go beyond the views expressed so far. How far back into childhood do our memories reach? I am familiar with some investigations on this question by V. and C. Henri[10] and Potwin.[11] They assert that such examinations show wide individual variations, inasmuch as some trace their first reminiscences to the sixth month of life, while others can recall nothing of their lives before the end of the sixth or even the eighth year. But what connection is there between these variations in the behaviour of childhood reminiscences, and what signification may be ascribed to them? It seems that it is not enough to procure the material for this question by simple inquiry, but it must later be subjected to a study in which the person furnishing the information must participate.
