BOSTON — It's hard to tell if a candidate is being honest, psychologists say it is possible to tell if they are feeling stressed.
Boston College Psychology Professor Joe Tecce says there are three clues anybody can use for the first debate between Hillary Clinton and Donald Trump.
1. Eye blinks
Eye blinks can signal uneasiness. Tecce has been watching file videos of both candidates for months. He found Trump blinks more than Clinton when answering questions, blinking an average of 65 blinks per minute to Clinton's 40 blinks per minute.
2. Head and shoulder movements
3. If they gaze away on a tough question
