7.Watch the eye movements of the person.
注意眼部動作
If a person is remembering something they tend to move their eyes up and in a left direction if they are right handed. If they are making something up, their eyes will move up and to the right. Left handed people do similar movements but in the opposite direction. People blink rapidly when they lie or they may rub their eyes. Eyelids also tend to close a little bit longer than a normal blink if a person hears something or sees something they don’t like.
