Recognition may be more or less complete. At its minimum, it is simply a "feeling of familiarity" with the object; at its maximum it is locating the object precisely in your autobiography. You see a man, and say, "He looks {358} familiar, I must have seen him somewhere", and then it dawns on you, "Oh! yes, now I know exactly who he is; he is the man who . . ." Between these extremes lie various degrees of recognition. This man seems to be some one seen recently, or a long, long time ago, or at the seashore, or as a salesman in a store; or as some one you looked up to, or felt hostility towards, or were amused at; and often these impressions turn out to be correct, when you succeed in fully recognizing the person. These impressions resemble the first signs of recognition in the baby's behavior; you say that the baby remembers people because he smiles at one who has pleased him before, and shrinks from one who has displeased him. Recognition described in terms of stimulus and response. Recognition is a form of learned response, depending on previous reaction to the object recognized. To recognize an object is to respond to it as we responded before--except for the feeling of familiarity, which could not occur the first time we saw the object. But notice this: though the object is the same identical object it was before, it may have changed somewhat. At least, its setting is different; this is a different time and perhaps a different place, and the circumstances are bound to be more or less different. In spite of this difference in the situation, we make the same response as before. Now, the response we made to the object in its original setting was a response to the whole situation, object _plus_ setting; our response to the object was colored by its setting. When we now recognize the object, we make the same response to the object in a different setting; the response originally called out by the object _plus_ its setting is now aroused by the object alone. Consequently we have an uneasy feeling of responding to a situation that is not present. {359} This uneasy feeling is the feeling of familiarity in its more haunting and "intriguing" form. We see some one who seems familiar and who arouses a hostile attitude in us that is not accounted for in the least by his present actions. We have this uneasy feeling of responding to a situation that is not present, and cannot rest till we have identified the person and justified our hostile attitude.
