We have already seen that the attention is implicated to a remarkable degree--in what I called "fluid attention" above--in the motor scholar.

The same implication of the attention occurs in all the sensory cases, but presents very different aspects; and the common fact that the attention is directly involved affords us one of the best rules of judgment and distinction.

We may say, generally, of the sensory children, that the attention is best, most facile, most interest-carrying for some one preferred sense, leading for this sense into preoccupation and ready distraction.

This tendency manifests itself, as we saw above, in the motor persons also, taking effect in action, speed, vivacity, hasty generalization, etc.; but in the sensory one it takes on varying forms.

This first aspect of our typical distinction of minds we may call "the relation of the 'favoured function' to the attention." Then, second, there is another and somewhat contrasted relation which also assumes importance when we come to consider individual cases; and that is the relation of the "favoured function"-- say movement, vision, hearing, etc .-- to Habit.
