Tune in tonight. USC prof on NOVA Science Now

Jennifer Vendemia, a psychology professor in the College of Arts and Sciences, is among the world’s authorities on deception and what happens in the brain when people lie.

David Pogue, New York Times technology columnist and host of NOVA Science Now on PBS, put Vendemia’s techniques to the test in late March. The show airs tonight (Oct. 17) at 10 p.m. on PBS.

Vendemia’s research, largely funded by grants from the Department of Defense, maps the areas of the brain that are involved in deception, looking at the precise brain-wave activity that occurs at the moment a person decides to lie. She has worked with the DOD’s Polygraph Institute since 2000.

Her findings have deepened researchers’ understanding of deception. She says multiple regions are involved in lying, and those regions can differ among people. What doesn’t vary, she says, is lying involves a decision, a choice between telling the truth or deceiving that is made in about 800 milliseconds.
