Be Negative to Your Children?

Should you be more negative to your children than anyone else? Should you treat your employees better than your children?  That's what's implied in this table from a post at Barking Up the Wrong Tree reporting research from this book.  The question is: if you want the best relationship, what's the ideal ratio of positive interactions to negative.  For example, parents should praise their children 3 times for each time they reprove them, etc.  If the research is right, I was a lousy boss.  

Of course the point is to be mostly positive to everyone.
