When we communicate non-verbally our bodies are literally expressing themselves. When Shakespeare said the eyes are the windows to the soul he was implying the eyes are the best non-verbal indicator of our emotional and intellectual state of mind. For example, we think of those who will not look us in the eyes as untrustworthy, dishonest, afraid or insecure. We think of those who have alert, expressive eyes as intelligent, energetic, and emotional. Our eyes have the power to judge, to attract, and to frighten.
Many parents can bring their children to tears, for example, without saying a word.
Our faces often express what we are not saying verbally. Our lips may tremble when we are afraid. Our forehead wrinkles when we are concerned or confused. And when people tap their fingers or feet they are usually feeling impatient. Research shows that those with high EQ are better at reading these non-verbal cues.
