Thus if we know a child has had sufficient opportunity to observe and acquire a behavioral sequence, and we know he is physically capable of performing the act but does not do so, then it is reasonable to assume that it is motivation which is lacking. The appropriate countermeasure then involves increasing the subjective value of the desired act relative to any competing response tendencies he might have, rather than having the model senselessly repeat an already redundant sequence of behavior.
Mom always said people worried too much about their children. Suffering when you're young is good for you, she said. It immunized your body and your soul, and that was why she ignored us kids when we cried. Fussing over children who cry only encouraged them, she told us. That's positive reinforcement for negative behavior.
Children are taught to look down on their nurses (nannies), to treat them as mere servants. When their task is completed the child is withdrawn or the nurse is dismissed. Her visits to her foster-child are discouraged by a cold reception. After a few years the child never sees her again. The mother expects to take her place, and to repair by her cruelty the results of her own neglect. But she is greatly mistaken; she is making an ungrateful foster-child, not an affectionate son; she is teaching him ingratitude, and she is preparing him to despise at a later day the mother who bore him, as he now despises his nurse.
