This is true of all questions of educational psychology.
This first distinction between children--as having general application--is that which I may cover by saying that some are more active, or motile, while others are more passive, or receptive.

This is a common enough distinction; but possibly a word or two on its meaning in the constitution of the child may give it more actual value.
The "active" person to the psychologist is one who is very responsive to what we have called Suggestions.

Suggestions may be described in most general terms as any and all the influences from outside, from the environment, both physical and personal, which get a lodgment in consciousness and lead to action.

A child who is "suggestible" to a high degree shows it in what we call "motility." The suggestions which take hold of him translate themselves very directly into action.

He tends to act promptly, quickly, unreflectively, assimilating the newer elements of the suggestions of the environment to the ways of behaviour fixed by his earlier habits.
