Narrator: This is Science Today. Computers
can be used for almost everything these days. Now,
they can even measure brain cognition. Dr. Louis Gottschalk,
a neuroscientist at the University of California,
Irvine, developed a computer program to help detect
hostility, anxiety - even brain disorders. All a person
has to do is talk into the computer for about five
Gottschalk: We've done studies of people coming
to a psychiatric outpatient clinic and got speech
samples and other measures and the five minute speech
samples, it gives scores on some fifteen different
psychological states and they tend to agree pretty
well with what the clinician finds out.
Narrator: The computer program is based on
the Gottschalk-Gleser scale, an international diagnostic
tool used to measure cognitive impairment.
Gottschalk: It's capable of summarizing mathematically
each score. So people send us material. Sometimes
on a patient. There's some doctors that get this,
get a five-minute speech sample and send me and use
it as they might a psychological test.
