In misreading, we encounter a psychic situation which is clearly differentiated from that of the tongue slips or pen slips. The one of the two rival tendencies is here replaced by a sensory stimulus and perhaps for that reason is less resistant. What one is reading is not a production of one's own psychic activity, as is something which one intends to write. In a large majority of cases, therefore, the misreading consists in a complete substitution. One substitutes another word for the word to be read, and there need be no connection in meaning between the text and the product of the misreading. In general, the slip is based upon a word resemblance. Lichtenberg's example of reading "_Agamemnon_" for "_angenommen_"[21] is the best of this group. If one wishes to discover the interfering tendency which causes the misreading, one may completely ignore the misread text and can begin the analytic investigation with the two questions: What is the first idea that occurs in free association to the product of the misreading, and, in what situation did the misreading occur? Now and then a knowledge of the latter suffices by itself to explain the misreading. Take, for example, the individual who, distressed by certain needs, wanders about in a strange city and reads the word "_Closethaus_" on a large sign on the first floor of a house. He has just time to be surprised at the fact that the sign has been nailed so high up when he discovers that, accurately observed, the sign reads "_Corset-haus_." In other cases the misreadings which are independent of the text require a penetrating analysis which cannot be accomplished without practice and confidence in the psychoanalytic technique. But generally it is not a matter of much difficulty to obtain the elucidation of a misreading. The substituted word, as in the example, "_Agamemnon_," betrays without more ado the thought sequence from which the interference results. In war times, for instance, it is very common for one to read into everything which contains a similar word structure, the names of the cities, generals and military expressions which are constantly buzzing around us. In this way, whatever interests and preoccupies one puts itself in the place of that which is foreign or uninteresting. The after-effects of thoughts blur the new perceptions. There are other types of misreadings, in which the text itself arouses the disturbing tendency, by means of which it is then most often changed into its opposite. One reads something which is undesired; analysis then convinces one that an intensive wish to reject what has been read should be made responsible for the alteration.
