What these studies have shown is that adults learn what they want to learn. Other things, even if acquired temporarily (e.g., for a test), are soon forgotten. Students, children, patients, clients, and subordinates may act as if they care about learning something, and go through the motions, but they proceed to disregard it or forget it—unless, it is something that they want to learn. This does not include changes induced, willingly or not, by chemical or hormonal changes in one's body. But even in such situations, the interpretation of the changes and the behavioral comportment following it will be affected by the person's will, values, and motivations.
