In the beginning I was right out of graduate school,
and I only had a couple of months--I was hired sort of late into the project,
and I only had a few months to set up the test battery.
So, I looked through the literature and I said, okay, here are the things
that everybody else has done. I'm going to do it, and we'll be able to assess it.
After about a year or so, I'm realizing that many of the patients we saw--
many of the people we saw who had traumatic brain injuries
that we knew had frontal lobe damage--
they were doing pretty well on these tests.
Fortunately for me, the wives and sometimes parents of these guys
started writing me because we sent them reports after somebody came--
even if this was a research project, we prepared a long report
that went back home with them--and they were saying we missed the boat.
And they were saying a lot of the problems that they were seeing we didn't study,
and this involved social behavior--how they were like at home,
how they got along with their children if they had young children,
what was happening with their work, could they maintain a job,
could they maintain back in school--
and we got lists of problems.
So, thanks to the caregivers--thanks to the wives and parents and
at that time parents of these guys--we were able eventually
to change a little bit of our test battery--certainly for Phase 3 and the current phase,
which has just ended now, Phase 4--
a lot of the studies we did were studies aimed at examining social behavior
in these veterans who have been incredibly dedicated to our study.
They come back all the time.
I think we're now much better prepared
to study everything from aggressive behavior
to attitudes, to the ability of somebody to understand what--
or to at least to guess what somebody else's intentions are in a conversation,
so we're much better able to do that now than we were 30 years ago,
and we're able to take experimental tests
and use them in a way that helps us better understand the outcomes
of somebody who's had a traumatic brain injury, so we're doing that now.

Thanks to the input of the caregivers of Vietnam vets enrolled in a longevity study, researchers have been better able to examine the toll of TBI on a person's social behavior.
