Narrator: This is Science Today. Anxiety is often
marked by an overwhelming sense of fear or worry.
But neuroscientist, Dr. Louis Gottschalk of the University
of California, Irvine says there are more subtle signs.
Gottschalk: We've produced hard data to show
that people who are anxious may focus on other people.
Or you'd think, well if somebody volunteers "but I
wasn't afraid, I'd jump from that airplane and I wasn't
afraid." They didn't have to say that. And we've demonstrated
that people that use denials - that may not always
correlate so highly with other measures of anxiety,
but it correlates pretty highly with biochemical measures.
Narrator: Gottschalk demonstrated this decades
ago with the Gottschalk-Gleser scale, an international
tool he co-developed to detect more than just anxiety.
Gottschalk: Hostility outward or hostility
towards oneself. We developed scales for how schizophrenic
somebody is, how depressed, how hopeful, how nurturing
or how much human relations somebody has.
