Learning II has had many names including ‘Deutero Larning’, ‘set learning’, ‘learning to learn’, and ‘transfer of learning’. It is change in the process of Learning I, e.g. a corrective change in the set of alternatives from which choice is made (Bateson 1972 p. 293). So when a change in the set of possible alternative responses is learned it will fall under the category of Learning II.
In other words if the dogs learn to learn to correct their response to a given stimulus they will have classified the contexts of learning I. Or more precisely, if Pavlov’s dogs were placed in a conditioning experiment under completely different circumstances and needed less time to correct their response to the stimulus, this would be Learning II. Learning II is learning to learn.
