Does your gaze betray you? Recent research shows that despite conscious repression, small movements of the eye do, in fact, indicate your true interest.
Normally, small movements (called microsaccades) of the eye flicker at random. But when an object enters your field of vision that interests you, those movements will tend towards it. Even if you are not aware of the attraction, the eye’s movement will tell.
If three objects are placed in front of you (an apple, a carrot and a chocolate bar) and you are told to stare at a point above them, a careful tracking of your eye’s movement will indicate your dietary preference… Even if you are on a diet.
