        For some kids who grow up in poverty, the
bond developed with Mom is especially important in dealing with stress.

But the part of the procedure that is most important to the researchers is what happens when the mother comes back.
It's how that baby greets or responds to her mother when she comes back that gives us some picture, some clue of the kind of history that these two have had together.
If a toddler is easily soothed by the mother, researchers conclude that their attachment is strong and the environment the toddler has grown up in is relatively secure. But if the toddler doesn't seem comfortable with the mother and can't be soothed, the researchers conclude that the attachment is poorer and the environment the child is growing up in is probably unstable.
It gives us some sense that that's probably the way in which those two have been interacting together over time.
Which finally brings us back to that original measure of breathing and heartbeats. The researchers found that the children who seemed less sensitive as infants ended up in the middle of the pack when it came to problem behaviors as toddlers. But kids who were sensitive as babies had two very different reactions to their worlds. If the baby had an insecure attachment to its mother, their behavior was deeply troubled, by far the worst. But if they had a secure attachment...
Those were the kids who were doing the best, the absolute best of all the other babies in our sample at a year and a half. They had far and away the lowest reported problem behaviors.
In fact, the behavior of sensitive children with secure attachments compared favorably to the behavior of children whose environments were often much, much easier.
These babies were looking a lot better behaviorally than a lot of babies growing up in middle-class and advantaged samples.
Better than a lot of babies growing up in middle-class and advantaged homes. So the researchers hope that this simple measure, breathing, heart beat, might one day be used to find sensitive children in poverty who need more stability and who prosper when they get it. They believe they found a biological marker which suggests that these children will be more sensitive to their environment, for better and for worse.
