One other fact in connection with repetition should be noted, namely, that the exercise given any connection by the learner, freely, of his own initiative counts more than that given under purposive learning. This method of learning is valuable in that it is incidental and often saves energy and possible imitation on the part of the child, but it has certain drawbacks. Habits formed this way are ingrained to such an extent that they are very difficult to modify. They were not consciously attended to when they were formed, and hence it is difficult later to raise them to the focal point. Hence it is best whenever habits are partial and will need to be modified later, or when the habits must later be rationalized, or when bad habits must be broken, to have the process focalized in attention. The methods of gaining attention have already been discussed. In the second place, if the habit being formed is connected with an instinct, the element of intensity is added. This, of course, means that a connection already made and one which is strongly ready to act is made to give its support to the new connection being formed. Of course the instinct chosen for this purpose must be in accord with the particular habit and with the nature of the learner. They may vary from the purely personal and physical up to those which have to do with groups and intellectual reactions. The added impetus of the instinct hastens the speed of the direction or supervision. The psychology of the value of self-activity is operative. It should be borne in mind, however, that the two kinds of exercise must be of the same degree of accuracy if this better result in self-initiated practice is to be obtained. Not only is it true that repetition makes for automaticity, but intensity is also an aid. Connections which are made emphatically as well as often tend to become permanent. This is particularly true of mental habits. There are two factors of importance which make for intensity in habit formation. First, the focalization of attention on the connections being made adds intensity. Bagley in his discussion of this topic makes "focalization in attention" a necessity in all habits. Although habits may be formed without such concentration, still it is true that if attention is given to the process, time is saved; for the added intensity secured increases the speed of learning. In certain types of habits, however, when incidental learning plays a large part, much skill may be acquired without focalization of attention in the process. Much of the learning of little children is of this type. Their habits of language, ways of doing things, mannerisms, and emotional attitudes often come as a result of suggestion and imitation rather than as a result of definite formation of the new habit.
