Is shouting the new spanking?

This article really hit home for me. We don't spank our kids, but every so often we do yell at them and then feel pretty bad about it afterwards. This article says that while there are many studies and data around spanking children and its consequences, there is much less certainty about the effects of yelling at them. We would prefer not to yell at them of course, but there are those moments...arghhhh!
