You may have watched the new series Lie To Me, with Tim Roth, based on the work of Paul Ekman.

The sec­ond episode, which you can watch for free via Hulu.com Here, is pretty inter­est­ing, but the best part hap­pens in the begin­ning, so you only need to watch a few min­utes to learn why what are called “lie detec­tors” are noth­ing but biofeed­back sys­tems that mea­sure phys­i­o­log­i­cal anxiety.

Biofeed­back can be a very effec­tive train­ing tool for emo­tional self-regulation and stress man­age­ment, pre­cisely because it enables a faster feedback-based learn­ing loop.

He trav­eled all over the world with pic­tures of peo­ple mak­ing dis­tinct facial expres­sions and found peo­ple in cul­tures every­where, from mod­ern to stone age, agreed on the emo­tion behind the expres­sion.
