When public manifestations survive, the extent to which the private stimulus takes over is never certain. In the case of a toothache, the private event is no doubt dominant, but this is due to its relative intensity, not to any condition of differential reinforcement. In a description of one’s own behavior, the private component may be much less important. A very strict external contingency may emphasize the public component, especially if the association with private events is faulty. (p. 423)
