All you've got to do is to watch them, to time-sample the behavior, and say, every five minutes, you ask the question, "Is it good, or is it bad?" If it's good, say, "That was really neat, thank you." That is such a powerful training technique.
Alles was Sie machen müssen ist, sie zu beobachten, das Verhalten in Zeitstücke zu teilen und, sagen wir alle fünf Minuten, fragen Sie sich, "Ist das gut oder schlecht?" Wenn es gut ist, sagen Sie "Das war wirklich klasse, danke."
