A couple of interesting bits from my last psych class:
This has been proven false. The main effect of waiting to attend to a crying baby is to get the baby to start screaming louder right away.
Also interesting when considering this with the studies saying that Japanese babies cry less than American babies and that Japanese mothers keep their babies with them more.
Guilt can be constructive when well placed. is when one feels bad about something they did, like if a kid takes or breaks another kids toy, and the adult tells him that the kid with the broken toy feels bad and that he should feel bad about that.
Shaming is destructive. An example is when the parent tells the kid that they're "ashamed of them," that they're such a bad kid for having done this or that and that they can't believe they've given birth to such a bad kid, or things of that nature.
