It's really difficult working with kids and with babies because they are not cooperative subjects: they are not socialized into the idea that they should cheerfully and cooperatively give you information. They're not like undergraduates, who you can bribe with beer money or course credit.

One way to make a baby cry is to expose it to cries of other babies. There's sort of contagiousness to the crying. It's not just crying. We also know that if a baby sees another human in silent pain, it will distress the baby. It seems part of our very nature is to suffer at the suffering of others.

Having kids has proven to be this amazing - for me, this amazing source of ideas of anecdotes, of examples, I can test my own kids without human subject permission, so they pilot - I pilot my ideas on them. And so it is a tremendous advantage to have kids if you're going to be a developmental psychologist.
