The Voice of Child Psychology is a small professor who appears to Donald in the 1954 animated short, Spare the Rod, in much the same way as his angel or devil did in previous shorts. He tries to teach Donald the ways of dealing with his mischievous nephews by understanding their psychology. The character is one of Disney's rare attempts at satire; in this case, of the spate of child psychology books that began to appear in the 50's. He was voiced by Bill Thompson.
