Are Chinese moms superior? Developmental psychologist Laurence Steinberg of Temple weighed in on that controversial claim by self-proclaimed "tiger mother" Amy Chua. Chua's book has drawn criticism for promoting harsh parenting techniques. "There are certainly elements in what she is espousing that have scientific evidence that they constitute good parenting. Kids need limits and structure, and it's good for parents to have high expectations for them," said Steinberg. "On the other hand...if parenting becomes too authoritarian ... those parenting practices have been shown to be related to elevated anxiety, depression and psychosomatic problems."
